Responsible Foundation Repair, Radon Mitigation Company Serving Strafford County, NH

Daniel H. of Farmington New Hampshire had experienced sagging floors in his home. He had known of this issue for a while and finally decided to fix it. 

Design Specialist Paul Magowan came to the home and found out that the support was compromised by insects. Paul proposed that they have SmartJacks installed in their basement. 

Crew Lead Jon Provost and his team came to the home and installed four SmartJacks into the basement of the home. The SmartJacks were installed and were able to boost up the house and level out the sagging floor.

Homeowner Markus R. purchased this home in Dover, NH in late 2020. Upon testing for radon levels in his home, Markus learned that the levels were around 8 pci/l, which is 4 levels above the recommended. He reached out to several companies for quotes for installation of a radon mitigation system. 

Design Specialist Royce Potts provided an exceptional inspection process and quote, and so Markus chose Erickson to complete the radon system for him. 

The installation process was completed by crew lead Branden Edwards, who finished the project in a single day. Based off of Royce's design, Branden was able to install all the necessary pipes in the basement area and up over the roofline, where the harmful radon would vent out. Additionally, when Branden was up on his ladder, he noticed the gutter was clogged up with debris, and so took it upon himself to clean it out for Markus. 

With a radon mitigation system in place, and a clean gutter as a bonus, Markus was very satisfied with the results of the project.

Chris S. of Durham, NH was experiencing some foundational issues under their garage that caused the concrete ceiling to start to crumble. Chris called EFS to see if they could assist in fixing his garage. Design Specialist, Nate Erickson, came out to the property and inspected the garage to see what is causing the ceiling to start to crumble. Nate found that in a cellar under the garage there is a crack that is caused the foundation to weaken. The crack has weakened the foundation which has caused movement and cracked the ceiling. Nate proposed that the Erickson Crew install a galvanized sheet to cover the crumbling ceiling, then installed a couple of beams that will span the width of the garage to secure the ceiling. Then to finish it off install PolyLEVEL to stabilize and level the foundation. 

Crew Lead Scott Crandall and his team came to the home and installed the galvanized sheets on the ceiling and then installed a couple of I-beams across the width of the garage.

After the sheets and I-beams were installed, a second crew came to the home. The PolyLEVEL Crew led by Nick Melo came to the home and injected PolyLEVEL into the areas that were out of level. 

Chris was happy to see that his garage was structurally sound again.

The homeowners of this 1985 home were seeing some 45 degree cracks in their second floor bedroom doors at the corners on both sides. There were some additional cracks in the closets and some nails popping in the stairwell. They were looking to get their home inspected to be sure they didn't have any serious foundation problems. One other thing to note is they two sump pumps, and fairly wet ground around the house which has been partially remediated but guttering and pouring a new basement floor in the addition portion of the house which was built in 1996. The homeowners were looking to renovate the upstairs but wanted to make sure they had no structural issues first.

Design specialist Brian Allen inspected the basement area of the home to determine why cracks were forming upstairs, and proposed the ideal solution for stabilizing the sinnking and settling areas of support. The lally columns under the main support beam in the home were gradually settling, and not providing the home with enough resistance and support. As the columns sank down, cracks in the drywall started appearing above in the home.

Our production team, led by Nick Carelli, installed several SmartJacks under the main support beam. The SmartJacks were placed over a secure footing of engineered fill to ensure they were properly supported for the weight of the home above. Additionally, they assisted the homeowner with better sealing the concrete around his existing sump pumps. 

The with floor fully stabilized, the homeowners were able to begin their remodeling plans in their home.

Homeowner James C. of Barrington was anxious to resolve his concerns with high radon levels in his home. He tested twice over the course of a year, and levels ranged between 5.8 and 13.8, well above the EPA's recommended level of 4.0 pci/l. James and his wife were planning to work from home more often, and so really wanted to improve the air quality where they would be spending the majority of their time. They received several quotes from contractors, and the most important factors to him were price, quality, and competency. 

Design specialist Michael LaMalfa provided James with a thorough inspection and detailed proposal for the radon mitigation system his home needed to help lower the levels of radon. Ultimately, James chose our Erickson team to install the radon mitigation system his home needed.

The home had a large footprint and so required two extraction points in order to ensure the radon levels were properly lowered. Crew lead Scott Crandall and his team successfully installed the entire system in a single day, and James has had peace of mind knowing his radon levels are now safely below 4.0pci/l.

Daniel H. of Farmington, New Hampshire was experiencing sagging floors. He called Erickson Foundation Solutions about a free inspection.

Design Specialist Paul Magowan came to Daniel's home and inspected his basement to see what could be done about the sagging floors. After the inspection, Paul proposed to install Smart Jacks. 

Crew Lead Jon Provost and his team came to Daniel's home and installed the Smart Jacks into the basement to stabilize the main support beam. 

Sharon and Paul D. of Farmington, New Hampshire recently purchased their home. They received a radon test when they purchased their home. The levels from the test came back at 7.9 pCi/L, which is high. They decided to call Erickson Foundation Solutions to see if someone could come out and educate them on Radon. The reason that Sharon and Paul want to hear more about a radon mitigation system is that one of their parents is coming for a visit. Paul and Sharon don't want to expose them to anything harmful. 

Design Specialist Paul Magowan came to the home and inspected the basement. He proposed that installing a radon mitigation system would help bring down the 7.9 pCi/l to a healthier level. The goal would be to have the pCi/l below 4.0 pCi/L, and Paul Magowan feels confident that a radon mitigation system will do that. 

Crew Lead Branden Edwards came to the home and installed the radon mitigation system into the basement. Sharon and Paul were very pleased to have the radon mitigation system installed before the parents arrived.

Sharon B. of Somersworth, NH had a home that had been with her family for 4 years. Her daughter also lived in the home, and they were planning to finish the basement area in order to create more living space for the grandchildren to play. The basement was damp and showed signs of mold concerns, especially in the spring when the ground outside was wet and humidity was up. Before making plans to remodel and finish the basement, they wanted to address this moisture concern. The last thing they wanted to happen was complete their finished space and have it destroyed by water.

Design specialist Jason Vachon met with the family to discuss their concerns and inspect the basement area. Jason designed a waterproofing system that would eliminate the risk of water damaging any of the basement and keep the moisture levels low. Jason also discovered signs of settlement, as well as noticed the front foundation wall was bowing in slightly, something to keep an eye on for future movement.

For the time being, Sharon and the family decided to complete the waterproofing aspect of the project. A Fast Drain and sump pump system was installed along the length of the wall that showed signs of water entering. Any water entering here in the future would be pumped out and discharged far away from the home's foundation walls. They will also keep an eye on the foundation wall cracks and the bowing wall. In time, they may also need to address these concerns before the problems or cracks get worse.

This homeowner in Lee, New Hampshire was experiencing radon levels in their basement between 8-9 pCi/L. They decided to call EFS for a free inspection.

Crew Lead Branden Edwards and his team arrived at the home and installed a radon system with 2 extraction points and sealed the cracks. 

This homeowner in Dover, New Hampshire was experiencing deteriorating fieldstone in their investment property. They decided to call EFS for a free inspection.

Design Specialist Jason Vachon arrived at the home and inspected the basement. Jason recommended installing an auxiliary wall to the fieldstone foundation to stop the wall from deteriorating from the inside. The basement also needed masonry block repair and over 100' of Water Guard and a Super Sump to be installed. 

Crew Lead Spencer Ladd and his crew arrived at the home and installed the auxiliary wall to the fieldstone foundation. The team also repaired the masonry blocks that needed attention. Finally, the team installed Water Guard and a Super Sump System.

Design Specialist Brian Swindell conducted an interior and exterior inspection of the home. Brian found cracks and movement caused by the car hitting the home. Brian recommended installing Geolocks and sealing the cracks in the foundation. 

Crew Lead Nick Carelli and his team arrived at the home and installed 5 Geolocks and 30' of crack sealant into the foundation wall. 

This homeowner in Farmington, New Hampshire was concerned about the radon levels in their home because of their young baby. To make sure that doesn't happen the homeowners decided to call EFS for a free inspection. 

Design Specialist Jason Vachon dropped off a radon test at the home. During the following days, the radon test continuously monitored the level of radon in the home. After the test was complete Jason came back to the home to collect the radon test and to go over the radon test results. The test results came back at 8.3 pCi/L which is high. Jason recommended installing a radon mitigation system in the home to help protect the new baby. 

Crew Lead Dillon Kingsbury installed a new radon mitigation system into the home. 

This homeowner in Durham, New Hampshire had recently inherited this home from his parents. He would like to have the home tested for radon. 

Design Specialist Michael LaMalfa brought a radon test to the home and set it up in the house to test how high the radon levels are in the home. When Michael came back to review the test results he found that the results were around 15 pCi/L. He recommended installing a radon mitigation system in the home. 

Crew Lead Dillon Kingsbury and his team installed a radon mitigation system into the house to bring down the radon levels to below 4 pCi/L.

A homeowner in Barrington, New Hampshire, had an issue where the floors in their home were sagging in various areas. The supports in the basement were timber and allowed the floors to sag and slope. The homeowner decided to call EFS for a free inspection. 

Our design specialist examined the floors and the supports and recommended installing SmartJacks with supplemental beams.

The crew installed 5 SmartJacks and 16 feet of supplemental beam.

A homeowner in New Durham, New Hampshire, had water coming into their finished basement. The water was ruining the finished space and the homeowners don't want to redo the basement again. 

Our design specialist recommended installing TripleSafe, WaterGuard, and IceGuard in the basement to collect the water and prevent it from ruining the finished space in the basement.

Our production crew installed The TripleSafe and WaterGuard into the basement in the basement and installed the IceGuard on the exterior of the home. 

The homeowner was relieved that their basement will no longer be damaged by unwanted water. 

A homeowner in Somersworth, Massachusetts, had some cracks in their foundation that they are concerned about. One year ago the home had the main beam replaced, and since then they have seen cracks in the foundation. Our design specialist Brian looked around the basement and the main living area of the home and found noticeable cracks in the foundation and other indications in the main living space. Our specialist recommended adding support to the foundation walls and under the main beam. 

Our production team installed PowerBraces on the foundation wall to strengthen the walls. The PowerBrace is a beam that is slightly taller than the foundation wall, the beam is mounted to the base of the wall with a plate and is secured into place by connecting to the joists. Using the bracket to connect to the joist the team can tighten the PowerBrace as much as they can to straighten a wall that has begun to bow. The team installed PowerBraces every few feet around the entire perimeter of the basement. After the team finished installing the PowerBraces the team began prepping to install the SmartJacks. To prep for the new supports, the team chipped out concrete where each SmartJack will rest. The team opens a 2'x2'x18" hole under the concrete and filled most of the hole with engineered fill then the top of the fill is covered with concrete for the SmartJack to rest on. Once the supports are connected to the main beam the team sets the footing of the SmartJack in concrete to lock them in place. Our team was able to address their foundation concerns and add stability to their foundation walls and the main beam of their home. 

Homeowners Carolin and Mark reached out to Erickson Foundation Solutions after noticing the old, wooden beams in her crawl space were showing signs of rot and sagging. Her main concern was that the rot would eventually lead to the wood beams giving out and the floor, or entire home, would begin to sink or collapse. Rot also means their is moisture in the air, which means there is also poor air rising up into the living space as well. 

Our specialist, Jason Vachon, conducted a thorough inspection and provided Carolin with a thorough analysis of her entire crawl space basement area, all within a few hours. The main concern Jason identified were the sistered beams and lack of support. The beams and joists spanned large distances, and as the wood aged and showed signs of rot, they began to bend and crack. Overall, the first floor of the home was going to need more supports from within the crawl space in order to properly stabilize the floor system. 

Jason also recommended crawl space encapsulation to cover the dirt floor and foundation walls. CleanSpace would be the perfect fix to address the moisture coming into the crawl space through the walls. The vapor barrier system, combined with a SaniDry dehumidifier, would most certainly provide a permanent solution to the moisture and rot concerns being faced by this damp crawl space.

Carolin was impressed by Jason's professionalism and the solutions he provided throughout his inspection. 

A homeowner in Barrington, New Hampshire, had a detached garage that had some cracks in the foundation. The homeowner wanted to install a jacuzzi on the second floor of the garage but they were worried about the strength of the foundation and wanted to address some water concerns in the basement of their home. They reached out to EFS for a free inspection. Our design specialist Brian recommended several of our products to address all of the issues in their garage and basement. The products that Brian recommended using were PowerBraces, Geolocks, FlexiSpan, SmartJacks, NexusPro, UltraSump, and IceGuard. 

Our team started by addressing the foundation walls. They began by installing 4 PowerBraces to the foundation wall in the garage. The PowerBraces works by using an L bracket mounted on the floor to brace the I beam against the wall. Then by using our system mounted in the rafters we applied outward pressure to stabilize the wall. After the PowerBraces were installed the team began installing the lone Geolock behind the staircase in the garage. The team started by digging a trench 10' away from the wall. The team then sends a rod through the foundation wall into the trench. On either end of the rod, the team attached Geolock Plates. After the plates were secured the team tightened the rod using a power drill. Once the plates were tightened the team backfilled the trench. Next, the team installed FlexiSpan on the wall to address some vertical cracks. The team chipped out some concrete at the bottom of the crack. This will create a path for the water to travel away from the home. After the concrete is chipped out, the team installed porous foam over the length of the crack and set it in place with an impermeable membrane that adhered to the wall. Following the team installing the Flexispan in the garage the team began installing the SmartJack. The SmartJack will add support to the floor when the homeowners install the jacuzzi on the second floor of the garage. The team started by chipping out some concrete where the SmartJack were going to be installed. The team dug down and filled the hole they dug with engineered fill and concrete to create stabile footing. The team waited for the concrete to cure. After the concrete was cured the team attached the SmartJack to the main beam and over the new concrete footing. After the SmartJack was secured the team covered the footing of the SmartJack with concrete to make sure it won't move. Following the installation of the SmartJacks the team moved into the basement to install some waterproofing. 

The team installed FlexiSpan and NexusPro into the basement to seal up some cracks that are allowing water into the basement. Next, our team installed an Ultra Sump in the corner of the basement. Any water that entered the basement will be collected by the UltraSump. Attached to the drainage line out of the Ultra Sump is an IceGuard that will prevent water from freezing in the drainage line. 

The homeowners are happy with the results of the project. They no longer have to worry about water in their basement and foundation concerns in their detached garage. Now they can install the jacuzzi on the second floor of their garage.  

A homeowner in Dover, New Hampshire, was checking the mail one day when a letter showed it was radon awareness month in their mailbox. Inside the piece of mail, they said they would send a free radon test kit to their home. The homeowners filled out the piece of mail and sent it back to get their free radon test. When the homeowner finally received the radon test in the mail they set them up and proceeded to test their home. The results of the test were between 8.4-10.6 pCi/L, which is above the recommended amount. Our design specialist John noticed during his inspection that the home had a passive radon system. John recommended activating the passive system into an active radon mitigation system. 

Our production team began by finding the passive radon system in the home. The team checked what condition the system was in, and decided to redo the radon pipe with PVC piping. The radon system started in the basement and made its way through the home and into the attic where it is vented through the roof. The team installed the radon fan in the attic where radon-filled air is pushed out of the home by the radon fan. By activating the radon system the radon levels in the home were reduced.

The homeowners are happy they no longer have to worry about the radon levels in their home. 

A homeowner in Lee, New Hampshire, planned to remodel their finished basement. The basement currently had high moisture and water coming in. The homeowner wanted to stop the water from coming in and reduce the moisture in the basement before they start remodeling the space. Our design specialist Brian recommended installing FlexiSpan, an UltraSump, Ice Guard, WaterGuard, and a SaniDry into the basement to stop the water and moisture from entering the basement. 

Our waterproofing team began by setting up a trench for the WaterGuard perimeter drainage system. The team used a jackhammer to chip out 42' of concrete big enough for our WaterGuard to be installed. The team fed the WaterGuard through the trench, they made sure to lead the WaterGuard to the area where we were installing the UltraSump. To install the UltraSump the team dug a basin big enough, then the team laid the sump pump into the basin and plumbed it. After the team plumbed the UltraSump they poured water down the WaterGuard to see if the water would collect in the sump and test the pump. After the team verified that the sump and perimeter drain worked, they moved on to seal a crack in the foundation that was allowing water into the basement. The team used FlexiSpan to seal the crack on the foundation wall. The FlexiSpan will act as a channel to collect the water that was entering through the crack and guide it into the perimeter drainage system. After the FlexiSpan was completed the team poured concrete over the WaterGuard and around the UltraSump basin to conceal it. The final step after the concrete cured was to install the SaniDry Sedona and connect its discharge line to the UltraSump. 

The homeowner is happy they can proceed with remodeling their basement without worrying about water entering their basement. 

A homeowner in Dover, New Hampshire had built this home in 1990. They have lived in the home for over 30 years and in late 2021 they noticed water entering their basement. The water has left the foundation wall looking unsightly so the homeowner decided to call EFS for a free inspection. Our design specialist Jason examined where the water was entering the basement and recommended installing FlexiSpan over where the water was entering.

Our Crew Leader Anthony began by taping around the affected area. Then he chipped out some concrete at the base of the wall to create a drainage point for the FlexiSpan. After he chipped out the concrete, Anthony then laid the FlexiSpan over where the water was entering the basement. The FlexiSpan will collect the water in a channel and guide it down a drain. Once the FlexiSpan membrane was installed, Anthony then poured some crushed stone into where the drain was, then he tied in the FlexiSpan in with the drainage, and lastly mixed some concrete to seal it up.

The homeowners were happy that water will not be entering their basement anymore. 

A homeowner in Dover, New Hampshire, lived in a home that was built in the early 1900s. The foundation of the home is half fieldstone and half poured concrete. The homeowners have lived in the home for 10 years and have always had water entering their basement. They decided its time to repair the problem so they call EFS for a free inspection. Our Design Specialist Isaac recommended installing 50ft of WaterGuard, a SuperSump, IceGuard, SaniDry, and a buried downspout. 

Our production team began by chipping out the concrete along two of the walls in the basement. The team chipped out the concrete so they could install 50ft of WaterGuard. At the end of the WaterGuard, the team dug a basin to install our SuperSump to pump out the water that the WaterGuard collects. After the WaterGuard was laid against the wall and the SuperSump was installed into the basin, the team then poured concrete around the basin and over the WaterGuard to conceal the system. While the concrete was curing the team installed the SaniDry next to the WaterGuard. The team set the dehumidifier up so it will drain into the WaterGuard. The team then plumbed the SuperSump so it would drain the water away from the home. On the drainage line from the sump, the team used an IceGuard to prevent the drainage line from backing up into the basement. Continuing after the IceGuard, the team buried the drainage line away from the home. 

The homeowners were very pleased with the results of the project. They no longer have to worry about water entering their basement. 

A homeowner in Rochester, New Hampshire, had lived in their home for the past 20 years, and every year since they purchased the home they had water enter their basement during periods of rain. The homeowners decided to call EFS for a free inspection. Our Design Specialist Jason inspected the home and recommended installing perimeter drainage around half of the basement and tying that into a new Super Sump, and then installing a FlexiSpan, and a Crack Monitor. 

Our production team started by installing a Supers Sump into the basement and then they installed 52ft of WaterGuard around half of the basement. After, the team then installed FlexiSpan to the foundation crack in the wall. After the WaterGuard, Super Sump, and FlexiSpan were installed, the team then installed a Crack Monitor and plumbed the drainage line for the Super Sump. 

The homeowners were very pleased with the results of the project. They no longer have to worry about water entering their basement. Our crew took two days to install our products and prevent water from entering the basement permanently. 

A homeowner in Rochester, New Hampshire, lives in a home that was built in 2004. The homeowner moved into the home in 2016 and then a couple of years later they started to notice cracks in the interior walls of the home. They contacted a structural engineer to see what was wrong with their home. They found that there isn't a foundation footing under their garage or their great room. The engineer declared the home as a structural failure. With this new information, the homeowners were forced to call a foundation company in their area. They reached out to EFS for a free inspection of their home. Our Design Specialist Victor provided a full inspection of their home while using the information that the engineer provided to the homeowners. Victor recommended installing Push Pier around the home and using PolyLevel to Frost mitigate around the home and fill the void under the slab in the garage. 

Our team was instructed by Victor's design to install Push Piers on the interior of the garage foundation and install more Push Piers on the outside for the foundation surrounding the great room. The team installed 11 Push Piers on the interior foundation of the garage and 13 more Push Piers to the foundation around the great room. After the piers were installed, the team then used PolyLevel to Frost Mitigation around the garage and then fill the void under the garage slab. 

Erickson was able to take this home that was deemed a structural failure and repair it. The homeowner was very thankful they contacted EFS to repair the foundation of their home.
