Job Stories From Hanover, NH
Water Entering a Family's Basement in Hanover, New Hampshire, with Matt Clark's Northern Basement Systems.

The Johnson family had lived in their home in Hanover, New Hampshire for over 20 years, but they had always struggled with water entering the basement. Every time it rained, they would have to rush to the basement to bail out water that had seeped in through the walls and floor. The damp, musty smell that resulted was not only unpleasant, but it was also harmful to their health. They had tried a variety of temporary solutions over the years, such as sealing the walls and installing a sump pump, but nothing seemed to work permanently.

One day, Mrs. Johnson was talking to a neighbor who had recently hired Matt Clark's Northern Basement Systems company to waterproof their home. They had been having the same problem as the Johnsons, but after hiring Matt Clark's team, they had not had any water in their basement since. Mrs. Johnson was skeptical but desperate, so she decided to give them a call.

When the team from Northern Basement Systems arrived at the family's home, they conducted a thorough inspection of the basement and the surrounding area. They explained to the Johnsons that the water was entering the basement due to a combination of factors, including the slope of the land around the house, the type of soil, and the age of the home. They then presented the Johnsons with a customized plan to waterproof their home permanently.

The plan included installing a drainage system around the house's interior perimeter and installing a high-quality sump pump to remove any water that managed to enter the basement. The team from Northern Basement Systems was professional and efficient, and they completed the job in just a few days.

The Johnsons were thrilled with the results. They no longer had to worry about water entering the basement and damaging their belongings. The damp, musty smell was gone, and their health improved. They were grateful to the team from Northern Basement Systems for solving a problem that had plagued them for so long.

In the years since Northern Basement Systems waterproofed their home, the Johnsons have not had a single issue with water in the basement. They have recommended the company to their friends and neighbors, and many of them have had similar success stories. If you are experiencing water in your basement, the team at Matt Clark's Northern Basement Systems is here to help. They offer a range of waterproofing solutions to fit your specific needs and budget. Don't wait until it's too late – contact them today and take the first step towards a dry, healthy home.

Crawl Space Repair & Encapsulation Banish Odor from Hanover, NH Home

George O. was tired of the musty smell from his crawl space invading his home. Desperate for a solution, George called Matt Clark’s Northern Basement Systems based on a recommendation from a colleague. Crawl space expert Michael Doherty came out to inspect the Hanover, NH home and look for the source of the odor!

Michael explained that removing moisture and keeping the crawl space dry was the only way to get rid of the smell – and keep it away! Foreman Matt Ostroud and his team encapsulated the crawl space, which solved several problems, smell included! After seeing the crawl space, the waterproofers suspected that plumbing leaks were partially to blame for the moisture and odor. They installed a SmartDrain crawl space drain and plumbing leak system to ensure the removal of any water that enters the crawl space. A SaniDry XP would help keep the air dry, preventing odor. Finally, the whole interior would be kept clean and dry with a CleanSpace liner and drainage matting.

George’s original concern was just with the smell of his crawl space. But having the space encapsulated provided the homeowner with many more benefits. His home is now more energy efficient, saving him a substantial amount on utility bills. And the space is clean enough to use for storing valuables!

New Homeowner Discovers Water Problem in Hanover, NH Basement

After researching businesses near Hanover, she chose Matt Clark’s Northern Basement Systems because she was impressed with their high standards and stellar customer reviews. She contacted them immediately and set up and appointment with waterproofing expert Justin Lanfranconi.

After Sharon approved the quote, Northern Basements team installed the products that Justin recommended. Sharon’s basement is now fully protected against the elements!

To keep the interior dry, a SaniDry XP dehumidifier and CleanSpace liner were also installed.

Foundation Settlement & Garage Floor Cracks in Rental Home in Hanover, NH

Ursula B. rented out her Hanover, NH home. When Ursula received complaints about cracks in the floor of the garage attached to the home, she owed it to the renters to call a professional and have the garage inspected. After doing some research, she decided that Matt Clark’s Northern Basement Systems was the right contractor for the job. Owner Matt Clark came out to conduct the inspection. He discovered that the garage had been built on loose soil and was quickly sinking into the ground, causing major cracks to the foundation. Matt assured Ursula that lifting and supporting the foundation right away would restore the garage to its normal place and ensure that the rest of the home would not be compromised.

After Ursula agreed to the plan that Matt proposed, Matt's team arrived to get started. They excavated the property and coated the foundation with additional concrete to seal and strengthen it. Next, they installed eight push piers. These long steel rods attach to the foundation and extend deep into the ground, anchoring in a more stable soil stratum. The foundation piers help to transfer the weight of the structure and prevent further settling and cracks.

Matt Clark’s Northern Basement Systems restored Ursula’s garage and her peace of mind. Her tenants can continue to live there safely and she can offer them a home she’s proud to own!

We recently had water in the basement for only the second time in 15 years - both times when the ground froze and it rained. I THINK the water came up through the drain in the floor. Thinking I might need a sump pump installed. You water proofed our basement crawl space a number of years ago.

I just bought an old home with crawl space. I need to have overall quote to clean the crawl space, overcome heat ill-insulation and have good insulation and sealing, prevent water accumulation and prevent rodent and insects infestation and easy access to all parts of the crawl space (some parts are inaccessible). Also, there are some un-even floors. I need to check the urgent things. If visits are on Saturdays, that will be the best.

Jason Yehle (Hazen Hill Construction) referred me to you -- I have water coming through my basement slab around the boiler/water tank platform, coming from spots that have clearly been patched before. There's always been a little bit of water (quarter to half-dollar sized) coming through for the last 5 years or so but we recently did a home reno and the problem seems to have worsened during the construction. Could also be from a radon pump installed relatively nearby. Wondered if you could come by and assess. Might have you take a look at a garage slab crack as well. We're in Hanover.

Our Foundation is part concrete slab, which I believe was part of the original foundation. There is also a small basement for portion of the footprint (I would say about 1/3). Another maybe 1/3 of the foundation I believe is on cinder blocks. That is the part that I am specifically concerned about and would like some evaluation around. Thanks. +Razvan
