Job Stories From Strafford County, NH
Smart Jacks Installation, Farmington, 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.

Radon Mitigation System, Dover, NH

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.

Garage Stabilization, Durham, NH

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.

Sagging Floors, Barrington, NH

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.

Radon Mitigation, Barrington, NH

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.

Radon Mitigation System, Farmington, NH

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.

Waterpoofing Basment, Somersworth, NH

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.

Sagging Floors, Barrington, NH

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.

Water Ruining Finished Space, New Durham, NH

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. 

Cracks in Foundation Wall, Somersworth, NH

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. 

Crawl Space Inspection, Dover, NH

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.

Detached Garage Has Foundation Issues, Barrington, NH

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.  

Activating a Passive Radon System, Dover, NH

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.
