Job Stories From Keene, NH
Bowing Walls in Keene, New Hampshire, with Matt Clark's Northern Basement Systems.

The Smith family had lived in their home in Keene, New Hampshire, for over 30 years, and they loved everything about it – the cozy atmosphere, the large yard, and the convenient location. However, they had always had one problem they couldn't solve – bowing basement walls.

The Smiths first noticed the problem when they started to see cracks in their basement walls and floor. They tried to ignore it at first, thinking it was just a cosmetic issue, but the cracks got worse as time passed, and the walls started to bow outward. The Smiths were worried about the structural integrity of their home and the potential for a collapse. They knew they had to do something before it was too late.

After researching, the Smiths decided to hire Matt Clark's Northern Basement Systems to permanently support their bowing walls. They had heard good things about the company and were confident they could solve their problem.

When the team from Northern Basement Systems arrived at the Smith's home, they conducted a thorough inspection of the basement and the surrounding area. They determined that the bowing walls were caused by hydrostatic pressure, the pressure exerted by the water's weight against the basement walls. They explained to the Smiths that this pressure could cause the walls to crack and bow, and if left unchecked, it could lead to serious structural issues.

A system design technician from Northern Basement Systems presented the Smiths with a plan to support their bowing walls using a power brace system permanently. The power brace system consists of steel beams anchored to the basement's floor and ceiling, supporting the walls and preventing them from bowing further. The team from Northern Basement Systems was professional and efficient, and they completed the job in just a few days.

The Smiths were thrilled with the results. They no longer had to worry about their walls collapsing, and the cracks in the walls and floor had disappeared. The power brace system was practically invisible, and it didn't interfere with their basement layout. The team from Northern Basement Systems had successfully solved a problem plaguing the Smiths for years.

Since Northern Basement Systems installed the power brace system, the Smiths have not had any issues with their bowing walls. If you are experiencing bowing walls in your basement, Matt Clark's Northern Basement Systems team is here to help. They offer a range of solutions to fit your specific needs and budget. Don't wait until it's too late – contact them today and take the first step towards a safe, healthy home.

Foundation Piers Help Stabilize Home Addition in Keene, NH

When John H. had an addition built on his home, he never expected that the addition might cause more problems than it solved! The addition on John’s Keene, NH home was completed in the 80s and over twenty years of foundation settlement lead to significant cracks in the drywall in the crawl space beneath the settlement, doors that wouldn’t open, and a severely tilted floor. John decided to have someone give him an estimate on repairs before it was too late. He found Matt Clark’s Northern Basement Systems online and filled out the request form on the company’s website. Shortly after, the company got back to him to set up an appointment, and specialist Michael Doherty came to inspect the home.

Michael suggested installing push piers and helical piers to transfer the weight of the structure to more stable soil. The piers help stop further foundation settlement, repair the cracks, and give John working doors and a level floor. 

John plans on contacting Matt Clark’s Northern Basement Systems every year to have his foundation inspected and is confident that the experts will be able to him if any problems should arise.

Keene, NH Homeowner is Thankful for Friend’s Recommendation for a Basement Waterproofer

Pete S. of Keene, NH told a friend about the water in his basement and the friend referred him to Matt Clark’s Northern Basement Systems. Pete set up an initial appointment and was pleased when owner Matt Clark came out to conduct the inspection! Matt knew exactly what the basement needed.

Matt decided that having foreman Refik Bahonjic and his crew install a WaterGuard XL drainage system and TrenchDrain channel drain would work the best to keep the water out of Pete’s basement. They also installed a TripleSafe sump pump and LawnScape drainage outlet to pump water out of the basement and away from the home. Finally, the experts used FlexiSpan to repair the crack in the wall where the water was coming into the basement.

Pete was happy that he spoke to his friend about his wet basement problem and that his friend recommended the perfect company for the job! The homeowner feels confident that his basement will stay dry and has had no issues with water coming into his basement.

Water Leakage Solved and Storage Space Created in Keene, NH Crawl Space

Lou and Cathy G. of Keene, NH thought they had taken the proper precautions to protect their crawl space. They already had a sump pump installed, but space never seemed to be totally dry. A friend of theirs had used Matt Clark’s Northern Basement Systems in the past to waterproof their basement. Lou and Cathy decided to give them a call and set up a free inspection and no-obligation estimate.

After the inspection, it was found that although the sump pump was doing its job, moisture permeating the soil was causing the damp environment. He recommended encapsulating the area to remove all the moisture. Lou and Cathy agreed to make their space dry and a bit more attractive in the process. Matt Clark's team installed CleanSpace drainage matting to collect the water from the soil, along with a CleanSpace liner to help keep the space dry. The couple also opted to include SilverGlo reflective wall insulation in the repair. Not only did the crawl space liner and insulation help create a healthier space, but these products also helped to brighten the floors and walls!

Lou and Cathy are very happy with the work of Matt Clark’s Northern Basement Systems and will no longer have to worry about mold or rot damaging their crawl space. Their home also has added value because the crawl space isn’t just wasted space - it is now a place where they can safely store their belongings!

We need some type of drainage system to get water away from the house. There is little/ no overhang of our 100 year old slate roof (and gutters are not an option) so the water falls against the house. We've had some flooding in our basement as a result that we'd like to prevent.
