We Are Conway's Most Dependable Basement Waterproofer Contractor

A homeowner in Conway, New Hampshire, had been dealing with a long-standing problem beneath their home — a damp, musty crawl space that never seemed to dry out. Over time, the moisture started to take a toll on the structure above. The homeowner began noticing soft spots in the floors, creaking noises, and a persistent odor that spread through the house. Concerned that these problems would only get worse, they reached out to Matt Clark’s Northern Basement Systems for help.

When the team arrived, a detailed inspection revealed what was happening. The crawl space had significant moisture buildup, and several wooden support beams had begun to weaken from humidity and rot. The dirt floor lacked a vapor barrier, allowing moisture to rise freely, and there was no drainage system to manage water seepage. The lack of structural support was causing visible sagging in the floors above. To permanently fix the problem, the crew designed a custom solution focused on both moisture control and structural reinforcement. The first step was installing a SmartDrain® System — a low-profile drainage solution explicitly designed for encapsulated crawl spaces. It collects any water or plumbing leaks beneath the vapor barrier and includes a WaterWatch® alarm to alert the homeowner if water is ever detected. Next, the team installed several SmartJack® Support Systems to stabilize and lift the sagging floors. These galvanized steel supports can be adjusted over time and provide a permanent fix that won’t shift or deteriorate like traditional wood posts. Finally, the space was sealed off to reduce humidity, improving both the home’s air quality and overall comfort.

Once the work was complete, the crawl space was transformed from a damp, unstable area into a clean, dry, and structurally sound space. The musty smell was gone, the floors above were solid again, and the homeowner could finally relax knowing their home was protected for the long term. Another crawl space in Conway, New Hampshire, was permanently repaired by the trusted experts at Matt Clark’s Northern Basement Systems.

In Conway, New Hampshire, a homeowner had just about had enough of their crawl space. Every time they went down to check it, they found damp air, a musty odor, and visible moisture on the dirt floor. The insulation was hanging down, the air felt heavy, and the space had become a breeding ground for humidity and discomfort. It was the kind of crawl space most homeowners hope never to see — and they wanted it fixed once and for all.

That’s when they called Matt Clark’s Northern Basement Systems. After a full inspection, the team found that years of moisture buildup had taken its toll. The crawl space lacked a proper vapor barrier, allowing moisture from the ground to evaporate into the home. Without a controlled environment, the air upstairs was being affected too — musty smells, uneven temperatures, and even higher energy bills.

The crew designed a custom plan to completely transform the crawl space into a clean, dry, and healthy part of the home. They installed the CleanSpace® Encapsulation System, a durable 20-mil vapor barrier that now covers every inch of the crawl space floor and walls. This bright white liner completely seals out ground moisture, instantly making the area look cleaner and more colorful. To maintain consistent air quality, a SaniDry™ Sedona Dehumidifier was added — one of the most potent, energy-efficient dehumidifiers available. It now works around the clock to remove excess humidity and keep the air fresh and dry.

By the time the job was complete, the transformation was remarkable. The homeowner could hardly believe it was the same crawl space. The odors were gone, the air was clean, and the home above felt noticeably more comfortable. What was once a damp, neglected area is now a sealed, protected, and energy-efficient space — another success story for the team at Matt Clark’s Northern Basement Systems.

A family in Conway, New Hampshire, began noticing uneven floors in their home. What started as a few creaks and soft spots soon developed into visible dips, causing furniture to tilt and making doors harder to close. At the same time, the crawl space beneath the home was damp and unprotected, with exposed soil and rising moisture creating a musty odor that permeated the living space. Concerned about both comfort and safety, the homeowners knew it was time to call in an expert.

They reached out to Matt Clark’s Northern Basement Systems, the trusted choice for crawl space repair in Conway, NH.

During our inspection, we confirmed that the crawl space was suffering from two major issues. The wooden supports beneath the home had begun to fail, leaving the floors above unstable. Additionally, the crawl space lacked a vapor barrier, allowing moisture to seep in and create an unhealthy environment continuously. To solve the problems once and for all, we recommend a combination of CleanSpace encapsulation and the SmartJack Support System.

Our crew first installed the CleanSpace® liner, a heavy-duty encapsulation system that seals the crawl space from ground moisture. This not only created a cleaner, brighter appearance but also protected the home from humidity and dampness. With the space properly sealed, we turned to the structural concerns. The failing wooden posts were replaced with SmartJack® supports—engineered steel columns that can be tightened and adjusted over time if needed. The SmartJack system lifted and stabilized the sagging floors, restoring the strength and safety of the home’s foundation.

Once the project was complete, the homeowners immediately noticed the difference. Their floors were level again, the musty odor was gone, and they had peace of mind knowing their home was protected with permanent solutions from Matt Clark’s Northern Basement Systems.

Winters in Conway, New Hampshire, can be long and bitterly cold, and one local family felt it every day through the floors of their home. No matter how high they turned up the thermostat, the floors stayed chilly, and drafts seemed to seep in from below. Additionally, their crawl space was damp and uninviting, with exposed soil and ineffective fiberglass insulation that had begun to sag and deteriorate. They worried about energy costs and the toll the cold, damp environment might be taking on their home’s structure.

Wanting a real solution before another winter set in, they contacted Matt Clark’s Northern Basement Systems, the local experts in crawl space winterization in Conway, NH.

During our inspection, it was clear why the family’s heating system was working overtime. The crawl space lacked a proper vapor barrier, and the old insulation provided little protection against the cold from creeping upward. To provide long-lasting comfort and safety, our team recommends a CleanSpace Crawl Space Encapsulation System paired with SilverGlo Insulation Panels.

The installation began with the crew carefully sealing the crawl space with the CleanSpace® liner. This heavy-duty barrier locks out ground moisture, brightens the area, and transforms the crawl space into a clean, controlled environment. Next, we insulated the crawl space walls with SilverGlo™ panels, which not only provide superior insulation but also feature a radiant barrier to reflect heat into the home. Together, these systems create a thermal and moisture barrier designed to handle the harshest New England winters.

When the project was complete, the once drafty crawl space had been transformed into a dry, energy-efficient part of the home. The homeowners immediately noticed warmer floors and a more comfortable living environment upstairs. Most importantly, they had the peace of mind knowing their crawl space was properly winterized and protected for years to come—all thanks to the team at Matt Clark’s Northern Basement Systems.
