Your home’s crawl space is often neglected. It’s usually too small to be seen as valuable and most people dread going into their crawl spaces because they are often damp and dark spaces that are so low they hurt your back. However, we feel like crawl spaces can be more valuable than that. We offer a variety of crawl space services that are guaranteed to turn your crawl space, regardless of the condition that it’s in, into an inviting and safe storage space. We can make any repairs that are needed and also encapsulate the space with a durable white plastic that brightens it up and creates a barrier from moisture.

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

A family in Winchester, New Hampshire, had a basement that had been experiencing problems with the walls for some time. The walls were bowing, and the family was concerned that they might collapse. They knew they needed to do something to fix the problem, but they weren't sure what to do.

After extensive research, the family learned about Matt Clark's Northern Basement Systems, which specializes in repairing and supporting basement walls. So they decided to call the company and set up a free inspection.

A system design specialist from the company came to the house and thoroughly examined the basement walls. They determined that the best course of action would be to install special Power Brace Wall Reinforcement Systems to reinforce the walls and prevent further damage.

Once the work was completed, the family was relieved to see that their basement walls were stable and secure. They were grateful to Matt Clark's Northern Basement Systems team for their expertise and for helping solve their basement wall problem. The family knew they could now rest easy, knowing that their home was safe and that their basement was no longer at risk of collapsing.
