A large crawl space in Sullivan, New Hampshire, was taking on moisture and had conditions similar to a short basement, with nearly five feet of height throughout much of the area. The homeowner wanted a permanent solution to help control water intrusion, reduce humidity, and create a cleaner, healthier space beneath the home.

 

Our team installed a full CleanSpace wall and floor encapsulation system over drainage matting to help direct water movement beneath the liner while protecting the crawl space from ground moisture. A TripleSafe sump pump system was added for reliable water removal, along with IceGuard protection to help prevent discharge line freeze-ups during harsh New Hampshire winters. The system was completed with a LawnScape outlet to ensure proper exterior drainage away from the home.

Crawl Space Repair & Encapsulation Expert

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. If moisture has already compromised your crawl space, we can offer complete wood rot repair for your crawl space.

Job Stories From Sullivan, NH
Crawl Space Waterproofing & Encapsulation in Sullivan, New Hampshire | Matt Clark's Northern Basement Systems

A homeowner in Sullivan, New Hampshire, contacted Matt Clark’s Northern Basement Systems looking for a permanent solution for a large crawl space beneath their home. With nearly five feet of height throughout much of the area, the crawl space had conditions similar to a short basement and was experiencing ongoing moisture concerns.

After completing a detailed inspection, our team designed a full crawl space encapsulation and waterproofing system to help control water intrusion and humidity beneath the home. To begin the project, drainage matting was installed across the crawl space floor to create a pathway for water movement beneath the system and enhance durability.

Next, our crew installed the CleanSpace wall and floor system to help isolate the crawl space from outside moisture and ground vapor. The bright white liner completely transformed the space's appearance while creating a cleaner, more controlled environment beneath the home.

To provide dependable water removal, a TripleSafe sump pump system was installed to handle water intrusion and provide multiple layers of protection. The discharge line was equipped with IceGuard to help prevent winter freeze-up issues common in New Hampshire, and the system was completed with a LawnScape outlet to direct water safely away from the foundation.

 

The completed project left the homeowner with a significantly cleaner, drier, and healthier crawl space designed for long-term moisture protection and peace of mind.
