Job Stories From Sullivan County, NH
Spring Melting Causing a Homeowners Basement to Flood Time and Time Again in Claremont

Shawn and Kayla Sullivan of Claremont, NH were plagued with a common problem many homeowners face: a leaky basement due to rain and snowmelt in the spring. The problem didn’t affect them every time it rained but was a serious issue for them nonetheless.

Their problem was like so many others that we face and after their free inspection, we were able to provide a solution that fit their needs.

To deal with the water coming into the basement DryTrak was installed. DryTrak is similar to WaterGuard in that it funnels all water to a pump; however, DryTrak is used for monolithic foundations and sits on top of the basement floor. For a pump, Shawn and Kayla decided to go with the TripleSafe pump containing two pumps in the event that one pump fails or that one pump can’t keep up with the amount of water, and a battery backup in case of a power outage. Along with the waterproofing, we installed a ThermalDry wall system that stops water vapor, drains wall leaks, and reflects up to 97% of the indoor heat back into the basement. ThermalDry wall systems are also perfect for homeowners that are considering finishing their basement at a later time.

In the end, Shawn and Kayla were very satisfied with the work and now have the peace of mind that their home won’t have water problems every spring.

Bowing Walls in Lempster, New Hampshire, with Matt Clark's Northern Basement Systems.

When the Thompsons noticed cracks forming in the walls of their basement and a noticeable inward bowing, they knew they couldn't ignore the problem any longer. Concerned about the structural integrity of their home, they reached out to Matt Clark's Northern Basement Systems for help.

Upon inspection, the experts at Matt Clark's Northern Basement Systems confirmed the Thompsons' fears: their basement walls were indeed bowing inward due to hydrostatic pressure from the surrounding soil. Left unchecked, this could lead to further damage and compromise the stability of the entire structure.

To address the issue, Matt Clark's team devised a comprehensive bowing walls repair plan tailored to the Thompsons' needs. The first step involved installing carbon fiber reinforcement strips along the interior surface of the bowing walls. These strips were strategically placed to provide additional support and prevent further inward movement.

Next, the team addressed the root cause of the problem by installing a foundation waterproofing system to alleviate hydrostatic pressure around the basement walls. This included installing a drainage system and triplesafe sump pump to redirect water away from the foundation and

With the bowing walls repair complete, the Thompsons could rest easy knowing that their home was once again structurally sound. No longer would they have to worry about the integrity of their basement walls or the safety of their family, thanks to the expertise of Matt Clark's Northern Basement Systems

When a homeowner in Claremont, New Hampshire, contacted Matt Clark's Northern Basement Systems for assistance with a severely bowed and cracked basement wall. Upon inspection, our team identified structural issues that required immediate attention. To address this, we recommended installing the PowerBrace wall support system.

The PowerBrace system is designed to stabilize and potentially straighten bowed or leaning basement walls over time. Our skilled technicians carefully installed the PowerBrace beams against the damaged wall, securing them to the basement floor and joists above. This installation provided crucial support and prevented further movement of the wall.

Over the following years, the homeowner noticed a remarkable improvement in the stability of their basement wall. The PowerBrace system effectively halted the progression of wall damage, giving the homeowner peace of mind and preserving the integrity of their home's foundation

Basement Waterproofing in Meriden, New Hampshire, by Matt Clark's Northern Basement Systems.

When the Roberts family of Meriden, New Hampshire, wanted to convert their basement into a home gym, they faced constant water intrusion, making it impossible to use the space effectively. They contacted Matt Clark's Northern Basement Systems for a permanent solution to their water problem.

During the inspection, the team identified that the basement was prone to water seepage through the foundation walls. They recommended installing a perimeter drainage system and a high-capacity sump pump. The Roberts were eager to proceed and scheduled the work.

The crew arrived on time and began excavating a trench around the interior perimeter of the basement.

The sump pump also included a battery backup for uninterrupted operation during power outages.

Once the system was in place, the team restored the basement floor and cleaned the area. The Roberts were impressed by the crew's professionalism and thoroughness. They could now create a home gym without worrying about water damage.

The Johnson family in Claremont, New Hampshire, had been dealing with a persistent water problem in their basement for years. Every heavy rainstorm would bring in water, leading to a damp, musty smell and the constant worry of potential damage to their stored belongings. They had tried DIY fixes, but nothing seemed to provide a long-term solution. That’s when they called Matt Clark’s Northern Basement Systems.

Now, the Johnsons can finally rest easy, knowing their basement will stay dry, even during the heaviest storms. With the professional waterproofing system in place, they have reclaimed their basement as a safe and usable space for storage and recreation.
