Job Stories From Gorham, NH
Basement Wall Repair in Gorham, New Hampshire, by Matt Clark's Northern Basement Systems.

The Smith family lived in a beautiful home in Gorham, New Hampshire, with a spacious basement they used as a playroom for their children. One day, they noticed that their basement walls were beginning to lean inward, causing cracks in the ceiling and at the top of the walls. They were worried their home was in danger of collapsing and didn't know what to do.

One of their friends recommended contacting Matt Clark's Northern Basement Systems, a company specializing in basement waterproofing and structural repair. They called the company and scheduled a free estimate, and soon a team of experts arrived at their home to assess the situation.

The team consisted of a system design specialist and a structural engineer, who worked hand in hand to identify the cause of the wall failure. They discovered that the walls were not correctly supported and were at risk of collapsing. They recommended installing a Power Brace Wall Support System to keep the walls and prevent further damage permanently.

Matt Clark's Northern Basement Systems quickly emerged and installed the Power Brace Wall Support System. The system consisted of steel beams attached to the walls and anchored to the floor and ceiling, providing the walls with the support they needed to stay upright. The installation process was completed in a few days, and the Smiths were impressed with the speed and efficiency of the work.

With the Power Brace Wall Support System in place, the Smiths were relieved that their home was safe and secure. They were also happy that they could save their beloved basement, which they had turned into a playroom for their children. The children could now play and have fun in their basement without any worries.

The Smiths were grateful to Matt Clark's Northern Basement Systems for saving their home and providing peace of mind. They recommended the company to their friends and family, and they continued using the basement as a playroom for many years.

Water in basement

Water seeping into the basement. I believe it is coming in through a crack.

Uneven floor on lower levels

Hi, We've gotten water in our basement twice now with heavy rains once in the spring and a few weeks ago when it rained several inches (we bought the house in 2019, not sure what was happening prior to 2019 but likely it's been an ongoing problem). Most of the time it stays dry but we would like for it to stay dry all of the time, even if we have heavy rain and during spring thaws. There is a pit and a pump but the water is coming up through the floor in a different spot. We're looking to have a solution installed. Thank you! Jennifer

I currently have water in the basement that is seeping through the floors and at times the walls. When we bought the house it had a sump pump already installed, however, it does not consistently work and the water levels get to near the top of the pit.
