A homeowner in Claremont, New Hampshire, was very uneased when she noticed her lally columns were getting very rusted at the bottom.  She researched the companies who could help her out and found Matt Clark's Northern Basement Systems to have the reviews and examples of prior work to give her high confidence in hiring them for the job.  After her free estimate, the crew went to work replacing the rusted lally columns with galvanized steel SmartJacks.  Her i-beam is securely supported, and the integrity of her home is back to being safe.

Job Stories From Claremont, 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.
