During a pre-purchase inspection, the home inspector for the home buyers tested the home for radon. The levels in the home were 52 pCi/L. The previous homeowner had lived in the home for 35 years and had no idea the radon levels were as high as they were.

Before moving into the home the new homeowner called Erickson Foundation Solutions for a free inspection. 

Design Specialist Stephen Caron inspected the home and determined 2 extraction points would be a minimum requirement to lower the high radon levels. But he recommended installing 4 total extraction points to ensure the radon levels are mitigated to a healthy level. The homeowner decided to start with 2 extraction points instead of 4, and agreed to upgrade to 4 extraction points if radon levels were still high after several months.

Crew Lead Dillon Kingsbury and his team installed two radon systems with the designed two extraction points. The mitigation system was designed to extract from both sides of the home.

Brian had found some water intrusion from the left foundation wall, so he recommended installing UltraSump, IceGuard, and FlexiSpan in the basement. 

Our production team began by digging the basin for the UltraSump. After the Ultra Sump basin was dug and installed, the team fed the drainage line to the exterior of the home. They connected an IceGuard to the drainage line to prevent water from backing up into the basement. Finally, the team used FlexiSpan to seal a crack on the foundation wall that allowed water to come into the basement. 

The team stopped water from entering the home and the buyer completed the purchasing process. 

A homeowner in Moultonborough, New Hampshire, built their home a little over a year ago. The homeowner owns homes in the past that had higher than recommended radon levels. They decided to test their new home for radon just to be safe. Our design specialist dropped off a CRM test to check the levels of radon that are currently in the home. The results from the CRM test were 11.2 pCi/L. Our design specialist Jason recommended installing a radon mitigation system.

Our production team began by chipping out an extraction point in the basement. The team chipped out a small section of concrete to attach a PVC pipe to the extraction point. Next, the team fed PVC pipe to the exterior of the home where they can install the radon fan. The team installed the radon fan onto the exterior of the home. After the radon fan was installed the team added more PVC pipe to the fan to vent the system above the roofline of the home. 

The homeowners were very happy with the radon system that was installed. They no longer have to worry about radon gas in their home. 

A homeowner in Center Ossipee, New Hampshire, had used this home as their second home since the 1970s but now they wanted to use it as their primary residence. To prepare for living in Center Ossipee full time the homeowners decided to have the home tested for radon. The homeowner placed a 24/7 radon monitoring system into the home to test the radon levels. The radon levels in the home were tested for 48 hours and the results came back with radon levels around 37 pCi/L, which was high. The homeowners decided to call EFS for a radon inspection, and our design specialist recommended installing a radon mitigation system with 2 extraction points. 

The production team began by creating the two extraction points in the basement, one in the northeast corner and the other in the southwest corner located in the utility room. The team chipped out a small section of the concrete floor to create the extraction point. The team connected PVC to each extraction point and then connected each extraction point together to lead to the radon fan. The radon fan was installed in the southwest corner of the home.

The homeowner is very happy with the results of the radon system being installed. The homeowners no longer have to worry about high radon levels in their home. 

A homeowner in Wolfeboro, New Hampshire, had the purchase of their new home under contract but wanted to have an eyesore addressed before they moved in. The whole home was in immaculate condition except for the garage floor. The garage had cracks all over and had become an eyesore. The homeowner called EFS because of our expertise in concrete repair and our design specialist recommended installing our 3-part concrete protection system.

Our production team began by injecting PolyLevel under the slab in the garage to fill any void. Once the team ensured that the void (if any) was filled, they then seal all of the cracks in the concrete with NexusPro. The team injected NexusPro into the cracks and smoothed it with a "spoon". After the NexusPro was installed the team then began spraying the concrete with SealantPro. SealantPro is a clear liquid that is sprayed over the surface of the concrete to protect the surface of the concrete from staining and accelerated erosion. 

The homeowner was very happy with the results of the project. They no longer have to worry about the garage being an eyesore for the home.

This homeowner in Sanbornville, NH was concerned with a stream of water entering his basement through some cracks and holes. The water was mainly leaking in through some holes where pool lines and irrigation lines exited the basement to the exterior of the house. The main goal of the project was to seal up these points in the foundation wall so that moisture would no longer be an issue in the basement. In the same vicinity as those water lines, water was also entering the basement through a crack in the foundation wall, right at a corner wall joint. Our waterproofing team sealed up all the necessary sections, holes, and cracks, with FlexiSpan and polymer injections, which will prevent any further water from entering in these locations. The homeowner was pleased with the results and happy with the way the crew cleaned up the work area.

A homeowner in Sanbornville, New Hampshire, had lived in the house for the past 2-1/2 years with little to no issues. That was until 2 days until Christmas 2022 when water started coming into their basement from the feed to their swimming pool. The homeowners decided to call EFS and our Design Specialist Jason recommended sealing around the pool feed using crack injection. Jason also found a crack near the pool feed line that could allow water into the basement. So he recommended sealing that crack as well. 

Our production team installed about 10' worth of crack injection around the feed line and the foundation crack to prevent water from entering the basement. 

The homeowner was very pleased with the entire process of the project. The team was able to install the crack injection into the basement and prevent water from entering the basement. 

A homeowner in Wolfeboro, New Hampshire, purchased their 1940s home 4 years ago. This past August the homeowners noticed sagging on their main floor. Then reached out to EFS for a free inspection and our Design Specialist Jason recommended installing SmartJacks to lift and add supports to the floors. The crawlspace under the floors was only about a foot tall so our team had requested the homeowners remove the floors before our arrival. 

Our team began by marking where each of the SmartJacks will be installed. We then removed and leveled the dirt where each SJ will be installed. The team made sure each footing was leveled before installing the SmartJacks. The team used a supplemental beam to add support across the floor joists so we could lift and level the floor. Our SmartJacks have an adjustable top so we can lift or drop the floor if needed. To finish the job our team lifted and leveled the floor, and then we installed subfloor plywood over the floor joists. 

The homeowner was very happy with the project. They were very impressed with the stability of the floor and how the SmartJacks were adjustable. 

A homeowner in East Wakefield, New Hampshire, was selling their home so they could escape the winters of the northeast. The homeowner has lived in their home for the past 22 years. When they purchased the home radon levels were low, but now the levels are higher than recommended. The levels in the home were around 14 pCi/L and need to be at or below 4.0 pCi/L. The homeowners decided to call EFS for an inspection of their home. Our Design Specialist Josh recommended and designed a radon system for their home. 

Our installation team began by creating an extraction point in the basement slab to collect radon from under the home. After the extraction point was made the team began installing PVC pipe to the extraction point and relaying the PVC pipe to the exterior of the home where we will install the radon fan on the exterior of the home. Once the fan and the PVC pipes were linked together the team then vents the system with more PVC above the roofline of the home where the radon gas can dissipate into the open air. 

The homeowner was pleased with the installation of the radon mitigation system into the home. They were now able to sell the home and move to a warmer climate. 

A homeowner in Moultonborough, New Hampshire, has lived in their home since it was built in 1985. This spring the homeowners went on vacation to Iceland and when they returned they found that their basement was flooded. After the water receded the team called EFS for a free inspection of their basement. Our Design Specialist Jason Vachon performed a full inspection of the basement and recommended installing a perimeter drainage system in the basement to collect any water and pump it to the exterior of the basement. Our perimeter drainage system included 108' of WaterGuard, a SuperSump, an IceGuard, an Exterior Drainage, and a SaniDry Sedona dehumidifier to protect the basement from water. 

Our Installation Team led by Gunther and Paul began by chipping concrete from the perimeter of the basement so we could install our perimeter drainage to collect any water that attempts to enter the basement. Next, the team installed the SuperSump and plumbed it to the outside of the home where we installed an IceGuard and an exterior drainage line to guide water away from the foundation. After, the team mixed up concrete and covered the WaterGuard and around the basin of the SuperSump to lock everything into place. After the concrete had cured, we installed our SaniDry Sedona next to the sump pump so the dehumidifier could drain into the basin of the pump. 

The homeowner was very pleased with the results of the project. Now the homeowners do not have to worry about water entering and flooding their basement.

A homeowner in Conway, New Hampshire, had just finished building their home in May 2023. Before they moved into the home an inspector looked over the entire home and had the home tested for radon. The results of the test came back with high radon levels. The results averaged around 21.3 pCi/L which is very high. The recommendation for the National Radon Defense is to have levels below 4.0 pCi/L. The homeowner decided to call EFS for us to design a radon system to lower the levels in their home. Our Design Specialist Jason Vachon met with the homeowners and inspected the basement to find the best space to install a custom radon mitigation system. Jason designed a system with 2 extraction points to lower the high radon levels to below the recommended amount by the National Radon Defense. 

Our installation team led by Steve Dumais began by creating the two extraction points in the slab of the basement. We used a 3" coring drill to make each extraction point. This will allow us to install 3" PVC pipes at each extraction point and feed them to the exterior of the home. On the outside of the home, we installed our radon fan and connected the PVC pipes. After the PVC pipe was secured to both the extraction point and radon fan we then vented the system above the roofline of the home so radon cannot re-enter the home. 

The homeowners were very happy with the result of the project. When the home was re-tested for radon after the system was installed the levels were under the recommended amount of 4.0 pCi/L.

The owner of a home in Freedom, New Hampshire contacted EFS after noticing some trip hazards on their detached garage slab. Jason Vachon, a design specialist from EFS, met with the homeowners and inspected the garage. He discovered that the slab had cracked and there were tripping hazards. Additionally, the front of the garage had sunk about 5 inches. Jason recommended installing 5 Push Piers, PolyLevel, and NexusPro to stabilize the foundation, lift the structure back to its original height, and seal the cracks in the garage.

Neal Foley and Nick Melo led the EFS installation team, which began by exposing the foundation of the garage. The team then installed Push Pier brackets onto the foundation and pressed 3' sections of piers until sufficient pressure was achieved. Once the piers were fully installed and the foundation was stabilized, the team backfilled over them and moved on to installing PolyLevel inside the garage. They created small port holes using a 1/2" drill bit to inject the PolyLevel beneath the slab, filling any voids and lifting any areas that needed lift. The team then plugged the holes with universal concrete and began sealing the 210' of cracks throughout the garage with NexusPro.

A homeowner in Middleton, New Hampshire, has owned their home for the past three years and is planning to finish their basement. To ensure proper support, they contacted EFS, and our Design Specialist, Jared Pavluvcik, inspected the existing supports. Jared determined that three SmartJacks needed to be installed, two to support a beam where a wall was knocked down and the third to replace an existing lally column.

Our installation team, led by Eric Witham, began by chipping out concrete from the basement slab to install footings below the slab. Then, they attached the supports to the beam above and used an adjustable top bracket to lift the beam and ensure it was level. Next, the team removed the lally column, replaced it with a SmartJack, and set up a temporary post. 

With the three SmartJacks installed, the homeowners were now confident to finish the area.

A homeowner in Bartlett, New Hampshire, purchased their home as a vacation home and moved things into the home in April 2023. While using the home during the summer months they had noticed condensation building up in the basement. They were worried this could lead to a full-blown water issue in the home while they weren't at the home. They called EFS to look at the basement so they could proactively get in front of this issue. Our Design Specialist Jason Vachon met with the homeowners and inspected the basement. Jason recommended installing a SuperSump, TrenchLock, IceGuard, and Exterior Drainage into the basement to eliminate the concern for water entering the basement. 

Our installation team led by Anthony LoCascio began by chipping out concrete along the foundation wall where the condensation was occurring. We chipped out 12 feet of concrete so we could install our sump pump and perimeter drainage. We installed the drainage and sump into the basement along the same wall as the water system. Next, the team plumbed the sump pump to the exterior of the home where we installed our IceGuard and EDL. The drainage line was 20 feet long to carry water away from the foundation wall so it could not re-enter the basement. After the exterior drainage was installed the team then mixed up concrete and poured it over and around the drainage and sump pump basin. Once the concrete cured the system was locked into place and would pump out any water that entered it. 

The homeowners now had peace of mind whenever they were at their other home. They didn't have to worry about water collecting inside the basement. 

A homeowner in Wolfeboro, New Hampshire was selling their home after living in it for over a decade. The house was on the open market and gathering interested buyers but the buyers would be scared when they would see a crack in the foundation on the back of the garage. After this had happened a few times the homeowners decided to take the home off of the market and fix the problem. 

The homeowners called EFS for a free inspection of the home. Our Design Specialist Jason Vachon met with the homeowner and looked at the foundation of the garage. Jason recommended installing 3 Geolocks on the back wall of the garage to pull the foundation wall back to its original position.

Our installation team led by Edward N. began by marking where each of the the Geolocks would be located on the foundation wall. Next, the team chipped out some concrete in the garage so we could dig a trench and install Geolock plates under the slab. The team set a threaded galvanized rod through the foundation wall and into the trench. Two plates were installed on either end of the rod and then they were tightened to straighten and stabilize the foundation wall. Once secured the team filled in the trench and poured new concrete. 

The homeowner was impressed with the results of the project. They were now able to put the home back on the market with confidence it would sell. 

A resident of Middleton, New Hampshire, purchased a lakeside cottage two years ago. They had noticed that the floors in their cottage were twisting and sagging. So, they contacted EFS for a free inspection of the supports under the floor system. Our Design Specialist, Jason Vachon, met with the homeowners and inspected the supports. After the inspection, he recommended replacing 12 supports with 12 SmartJacks and 64' of Supplemental beam to stabilize and level the floor system.

Our installation team, led by Ed N., set up temporary posts in the crawlspace to support the floor while they removed the old supports and installed the new SmartJacks and Supplemental Beam. The team installed big plate footings on the dirt floor to provide a base for the SmartJack to support the floors. Once the footings were secured, the team cut the SmartJacks to the correct size and installed the top brackets and Supplemental beam. Once all of the supports were in place, the team began to tighten the top brackets to lift and level the floor system, using laser levels to ensure that the floors were perfectly flat.

Finally, the team cleaned up the crawlspace and showed the homeowner their new SmartJacks. The homeowner was very pleased with the results of the project.

Scott and Tamara of Mirror Lake, New Hampshire are in the process of multiple home projects. One of the projects that they are prioritizing is creating a safe and sustainable crawl space. Knowing the importance of a strong foundation, Scott and Tamara reached out to our Erickson Foundation Solutions team to enhance their crawl space.

After discussing concerns with one of our Customer Care Specialists, an appointment to meet with one of our Design Specialists was scheduled. Jason Vachon came and inspected the crawl space, as well as other areas of the home. After consulting with Scott and Tamara, Jason recommended installing our CleanSpace vapor barrier and SaniDry Sedona dehumidifier. The CleanSpace vapor barrier encapsulates the walls and floor of the crawl space. This keeps moisture out of the crawl space, which prevents high humidity, condensation, wood rot, and insects/critters. It also acts as a form of insulation, which helps with drafts and cold floors. The SaniDry Sedona dehumidifier creates a comfortable living space by improving air quality. Mold and other toxins are removed, creating a safer environment for the entire home.

After installing these two systems, a waterproofed crawl space has been created. Scott and Tamara are thrilled knowing that the rest of their home projects will be supported by a solid foundation.
