Foundation Repair & Radon Mitigation Specialists in Derry, NH

This homeowner in Derry, New Hampshire, has lived in their home for the past 7-8 years. The home was built in 1984 but when they bought it in 2015 they noticed that the bulkhead allowed water to leak into the basement. Now 7-8 years later the bulkhead is still allowing water into the basement so they decided to call EFS for a free inspection of their bulkhead and basement. Our Design Specialist Bryan Barnard met with the homeowner and inspected the bulkhead and the basement to find a solution to stop the water from leaking in. After his inspection, Bryan recommended installing a new bulkhead.

Out Installation Team led by Bob Labrie and Brendan Edwards began by removing the old bulkhead from the home. Once removed, the team began to install the new bulkhead. We made sure to seal around the edges of the bulkhead to make sure water couldn't travel under or around it and get into the basement. Once everything was installed the team did a walkthrough with the homeowner to show them everything that was installed. 

The homeowner was very pleased with the look and functionality of the new bulkhead. 

A homeowner in Derry, New Hampshire has lived in their early 1900s home for almost 2 years and has noticed that the floors were sloping. The homeowner decided to call EFS for a free inspection. Our Design Specialist recommended installing SmartJacks into the basement to eliminate any sagging and sloping of the floors.

Our team began by chipping out sections of concrete in the basement so we could install our SmartJacks to the floor system of the home. Once the concrete was chipped out the team installed our footings and then cut our SmartJacks to size so we could attach them to the floor system. The team attached the SmartJacks to the floor system by using an adjustable top and some heavy-duty screws. Once attached the team was able to use the adjustable top and lift up on the floor system. After the floor was adjusted the team then mixed concrete and set the footings of the SmartJacks in concrete. 

The homeowner was impressed by our SmartJacks fixing the sloping and sagging floors in their home. 

A homeowner in Derry, New Hampshire, has lived in their home for the past 13 years. About 2 years ago the homeowners have noticed water entering their basement from their bulkhead. They tried to repair the issue themselves with a bandaid fix but less than a year later the fix didn't hold up. Now the homeowners would like to find a permanent fix so they reached out to EFS for a free inspection of their basement. Our Design Specialist Victor inspected the basement and recommended using a combination of WaterGuard, TrenchGuard, CleanSpace, and an UltraSump to collect any water that enters the basement. 

Our installation team began by installing our UltraSump on the wall next to the bulkhead. The team chipped out some concrete and removed some dirt so they could install the sump pump flush with the floor. Then they plumbed the sump to the exterior of the home and installed an IceGuard and an exterior drainage line too. Next, the team chipped out the perimeter of the bulkhead and along the wall that the bulkhead was on so we can install our WaterGuard against the walls to collect any water. The WaterGuard will all lead back to the UltraSump so it can send the water out of the basement. Additionally, on the bulkhead walls, the team installed CleanSpace to direct the water to the WaterGuard which will be sent to the UltraSump. 

The homeowner was very pleased with the results of the project. They haven't seen any water in their basement since EFS installed the perimeter drainage system. 

A homeowner in Derry, New Hampshire, had moved into their home at the beginning of 2022. The house was built in late 2021 and after living in it for almost a year they noticed a crack in their garage and the garage apron was deteriorating. The homeowners wanted to preserve their new home and prevent things from getting worse. They decided to call EFS for a free inspection and our Design Specialist recommended repairing the apron and sealing the apron. 

Our production team began by chipping out the apron of the garage. After the old apron was removed the team then set up a form to pour a new one. Once they poured and smoothed the apron they had to wait for it to cure, so they then used NexusPro to seal the crack in the garage. To prevent any further cracking the team injected some PolyLevel under the garage slab to fill any voids under the concrete. 

The homeowners were very happy with the results of the project. They don't have to worry about their garage deteriorating anymore. The homeowner can now focus on keeping the rest of their home in good condition for years to come. 

The owner of a duplex in Derry, New Hampshire, has owned the duplex for 12 years. The duplex was built in the 1980s and they noticed the Bulkhead door that leads into the split basement had seen better days. The owners would like to replace the bulkhead door, so they decided to call EFS for a free inspection. Our design specialist measured the bulkhead opening and recommended a bulkhead for the owners. 

Our production team began by removing the old bulkhead from the duplex. After the old bulkhead was removed the team then began to set up the new bulkhead. The team installed the bulkhead and made sure it was secured and sealed correctly. 

The owners were happy with the look of the new bulkhead. 

A home in Derry, New Hampshire, had been put on the market. A potential buyer asked if someone from EFS could inspect the home's foundation before they think about purchasing the home. Our design specialist inspected the home and found some bowing and settlement in the foundation walls. The potential buyer was still worried about the foundation issues. The design specialist presented a solution. The solution was to install 7 PowerBraces to the back foundation wall and prevent the wall from bowing further.

The potential buyer ended up purchasing the home. After the purchase was complete, our production team installed the braces onto the foundation wall to add strength and rigidity to the wall.

A home in Derry, New Hampshire, recently had EFS install Geolocks to the rear of the garage to stop the garage from collapsing. Our team stabilized the garage foundation and then needed to level the garage slab and seal the cracks in the slab.

In the past 2-3 years they started to notice some cracking in the detached garage floor along with some sinking in some areas.

They decided to call EFS for a free inspection.

Michael found that the back of the garage is getting pushed out causing a crack in the foundation. Michael recommended installing Geolocks to pull that back wall in.

Design Specialist Chris Greenwood did a full interior and exterior inspection of the home. During his inspection, Chris had found some more cracking on the exterior of the foundation. Chris found the root cause of the cracks in the foundation is because the home is sinking on one side. For a foundation to start sinking it could be that there is poor water drainage, poor soil under the home, and some other root causes. Chris advised the homeowner that installing Push Piers to the home will stop the home from sinking. The homeowner agreed.

Crew Lead Scott Crandall and his team arrived at the home and installed 10 Push Pier to the foundation.

Jennifer C. of Derry, New Hampshire had previously been a customer of Erickson Foundation Solutions in 2018. Previously, she had water entering her basement from the back of the home. She had a Fast Drain System and 2 sump pumps installed in her basement. Currently, she has water entering her basement from the front of her home and would like to have that repaired. Like she did in 2018, she reached out to Erickson Foundation Solution for a free inspection. 

Design Specialist Jason Vachon arrived at Jennifer's home and inspected her basement for cracks. Jason found two cracks in the foundation that are right behind where the front stoop is. Jason recommended to Jennifer that it would be a good idea to have the EFS crew install Sentry Seal around the front of her foundation so that no more water can enter the basement. 

Crew Lead Brandon Edwards and Installation Specialist Kyle DeChane and Brian Somers came to the home and installed Sentry Seal. The team had to dig and expose the foundation. Once the foundation is exposed, they attached the Sentry Seal to the foundation wall. The Sentry Seal will not allow any water to enter the basement.

This homeowner in Derry, New Hampshire lives on Beaver Lake and has been experiencing unlevel floors and the corner of their porch is sinking. Design Specialist Royce Potts came to the home and walked through the home and the basement to better understand what conditions the house was in. He suggested that they install SmartJacks in the crawlspace of the home to add support and lift it some. 

Crew Lead Scott Crandall and his team came to the home and installed the SmartJacks into the crawlspace. Using the SmartJacks gave the home some interior support and some lift. The homeowners were very happy with the results of the project.

This customer was having a sunroom installed on top of their existing deck. The deck was not built for supporting a structure above, and so additional supports were needed below. There was only about 3.5 feet of space beneath the deck, and so getting underneath to dig and pour new concrete piers would not be an easy task.

EZ Posts were an ideal solution, as the existing deck floor was going to be completely covered by the sunroom. This allowed our Erickson Foundation Supportworks crew to cut small holes into the surface of the deck. Through these holes we were able to install EZ posts with our Bobcat using pier extensions.

A project which would have taken 2-3 crew members one or more days to complete was finished within 4 hours. The EZ Posts were installed at depths ranging from 7 to 9 feet. We removed some concrete pillars in order to install two of our EZ Posts, these concrete pillars being only two feet deep. It was a good decision to replace them!

This homeowner in Derry, NH contacted us as she noticed a large crack in her garage wall near a corner. Upon inspection, our design specialist observed there were few signs of settling within the house aside from windows being slightly stuck. However, on the outside of the garage, there were significant signs of sinking which would then lead to extensive damage within the home. 

The solution; push piers to raise the sinking corner 3-4 inches and prevent the foundation from sinking any further. 

We excavated the outside of the garage down to the footing of the foundation. We found the general contractor who built the home placed the footings and foundation directly on stumps and trees, which of course is a big mistake. As the trees decomposed, the ground began to sink and took the foundation with it. 

Our push piers were securely fastened to the bottom of the footings on the foundation and driven down 10-12 feet, beneath the sinking soil and into the bedrock below. This will prevent the home from sinking any further. We also slightly lifted the footing up to the bottom of the foundation to reconnect them, however chose to not lift the house too much as there was little damage within the house. Lifting the house too much could possibly have cracked the drywall.

Problem solved and customer satisfied.
