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.
