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 Gilmanton, NH
Fixing a Basement in Gilmanton, New Hampshire, by Matt Clark's Northern Basement Systems.

After inheriting a home in Gilmanton, New Hampshire, a decision was made to sell the home.  The new owner lived across the country and was an extremely busy person.  They decided they would hire a contractor and realtor to help with the process.  During the inspection of the home, the contractor noticed many signs of water entering the basement.  

Having worked with Matt Clark's Northern Basement Systems many times throughout the years, he had great confidence in recommending them to be waterproof and structurally repaired the home's basement. 

Northern Basement Systems went into the basement and structurally supported a failing wall with a Power Brace System. 

After, Northern Basement Systems installed a custom-designed waterproofing system to ensure the basement would turn into a dry, clean useable space.
