Job Stories From Laconia, NH
Drain and Sump Pump Installation in Laconia, NH

These homeowners called Northern Basement Systems after their finished basement rug floor started getting very wet. They were concerned about water damage to their belongings and investment in this space. We provided a free estimate and then began the project right away. The team started by cutting the walls and pulling back the carpet to access the bottom wall to install WaterGuard and the TripleSafe Sump Pump systems. After installation, the team framed and sheet rocked around the system and concealed it to return the space to its original condition prior to the water entering the basement. This left the homeowners with a worry-free solution to keep their finished space dry.

SaniDry XP Keeps Finished Basement Comfortable in Laconia, NH

Jim and Natalie S. of Laconia, NH had their basement finished a while ago, but the air always seemed to be damp, so they found themselves never really wanting to spend time in their basement. The couple was worried that they may have remodeled their basement for nothing. They decided to contact a basement specialist to inspect their basement and suggest any possible options for repair. A Google search provided the homeowners with a few options of waterproofers in the area, but Matt Clark’s Northern Basement Systems seemed to the best fit for the job. They had numerous certifications and great reviews!

Basement expert Justin Lanfranconi inspected the basement and suggested installing a SaniDry XP dehumidifier to remove moisture from the atmosphere. Rather than installing the system in the finished room itself, where it would be unsightly, the team placed it in the adjacent, unfinished part of the basement. Wall ducts installed in the finished area of the basement connected to the dehumidifier and offered a discreet method for conditioning the environment.

Before contacting Matt Clark’s Northern Basement Systems, Jim and Natalie were not even sure that their problem could be fixed. Not only did the company prove the couple wrong, but the team also outdid itself when they took the basement’s appearance into consideration. Now, space is an enjoyable place to relax on the weekends!

Waterproofed Basement Adds Storage Space for Laconia, NH Homeowner

Sue C. of Laconia, NH recognized that her basement was leaky, but she did not feel pressured to have it fixed until she ran out of storage space in the rest of the house. Sue heard of Matt Clark’s Northern Basement Systems and decided to check out their website. After submitting a request for an estimate online, a representative called Sue and set her up with an appointment with a waterproofing expert.

Northern Basement Systems installed a complete waterproofing system, including TrenchDrain channel drains and a WaterGuard XL drainage system. They also installed a SuperSump sump pump and a LawnScape drainage outlet. An IceGuard drainage line device was also added to ensure proper water drainage even if the lines freeze or become clogged. Finally, the team covered the basement with CleanSpace waterproof liner to help protect Sue’s belongings.

Thanks to a job well-done by the team at Matt Clark’s Northern Basement Systems, Sue has peace of mind knowing that damp conditions will never damage the irreplaceable items in her basement!

Two Wet Crawl Spaces Repaired Underneath One Laconia, NH Home

David R. of Laconia, NH faced a nightmare twice the size of other homeowners. Both crawl spaces beneath his home had wet dirt floors. His old access well, which had rotted and corroded over time, probably contributed to water reaching below. David wanted a professional opinion on what to do to fix his crawl spaces. Researching products that would fix his problem brought David to Matt Clark’s Northern Basement Systems’ website. He called to discuss what the company could do for him and set up a free, no-obligation estimate.

 A SmartSump sump pump installed in one crawl space and a SmartDrain in the other would help expel the excess water. CleanSpace drainage matting and a crawl space liner would also keep the space dry, since the matting transports the water to the drainage system, and the liner seals the interior of the space.

David is happy with the results of the crawl space waterproofing and repair job and has since seen his energy bills decrease dramatically! The homeowner is thankful that he contacted the experts at Matt Clark’s Northern Basement Systems.
