Retaining Wall Replaced and Wall Cracks Repaired in Lebanon, NH

Peter and Alyssa J. knew that trouble was brewing beneath their Lebanon, NH home. Countless cracks had emerged in both exterior and interior walls along two sides of their home, and their retaining wall was cracked even more and bowing precariously. Fearing that they would need to replace their foundation, the couple contacted Matt Clark’s Northern Basement Systems after they discovered that the business did much more than just waterproofing!

Foundation expert Nicholas Farnham came out to inspect the foundation and assured the homeowners that foundation replacement was not necessary.  Nick came in a plan which included replacing a retaining wall and installing wall anchors to straighten the walls, provide extra support against the outward pressure and reattach them to the foundation. Even though the project was extensive, Peter and Alyssa were happy that the work could be done for less money than they anticipated! Soon enough, the cracks were no longer visible and the new retaining wall looked better than ever!

Peter and Alyssa are happy to have found the right team to handle their structural issues.

Homeowner in Lebanon, NH Services Her Waterproofing System Every Year!

A few years ago, homeowner Gayle M. of Lebanon, NH needed her basement completely waterproofed. At the time she had nothing in place to protect her property from the water damage of heavy rains or hard winters. Gayle contacted Matt Clark’s Northern Basement Systems to install a waterproofing system.

Northern Basement Systems installed a WaterGuard XL drainage system and TrenchDrain channel drains to collect the water, a TripleSafe and SuperSump sump pumps to remove the water, and a SaniDry XP dehumidifier to keep the environment dry. Gayle was impressed at the amount of work done in so little time, and felt secure in her home once again.

Every year, Gayle calls upon the experts at Matt Clark’s Northern Basement Systems to inspect her system, clean it as necessary and replace the filter in her dehumidifier. Having the system serviced ensures that everything is working properly and prevents any possible issues from turning into a disaster. Gayle is happy to have an expert she can trust and since they did such a good job the first time, there’s rarely anything that needs to be done!

Home Show Leads Lebanon, NH Homeowners to a Drier, Brighter Crawl Space

Joe and Rosie S. attended the HomeLife Show in Hanover. Thinking about the damp crawl space beneath their Lebanon home, the NH homeowners decided to talk with a representative from Matt Clark’s Northern Basement Systems after hearing an expert talk about the dangers of a damp, unsecured crawl space because and how it can affect the rest of the home. The representative discussed cost-effective options to seal their crawl space and create a healthier environment. Joe and Rosie thought that the company would be a good fit for the job and set up an appointment with specialist Michael.

Expert Michael came out for the inspection and provided a free, no-obligation estimate for the suggested repairs. The couple was lucky – as of yet, they had no major structural or water damage problems. Michael indicated that the foreman install a CleanSpace liner to encapsulate the space to keep out moisture and water. CleanSpace crawl space encapsulation provides a barrier between the crawl space floor and the earth.   

Joe and Rosie are thrilled that their crawl space is now clean and dry, and they also have extra storage space and have added value to their home in the process.

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!

New Homeowner Discovers Water Problem in Hanover, NH Basement

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!

Replacing Carpet with ThermalDry Floor Tiles

Alexei woke up one morning to find that her finished basement had undergone some water damage. This ruined the carpet and left other items damp. She didn’t want to replace the carpet, because the same damages could happen again. She figured there must be something that could better protect her basement floor. After doing some research online, she found the solution. She quickly reached out to Matt Clark’s Northern Basement Systems for help.

Alexei checked out the Northern Basement Systems’ website and found the ThermalDry floor tiles. These tiles are designed specifically for basements. They are warm, comfortable and stylish. Each tile is designed to sit on raised, plastic pegs, forming a small airspace underneath. In this airspace, water vapor circulates and dries out. This causes the tile to be eight to ten degrees warmer than the concrete below it. The tile is made from inorganic material; this will ensure that plumbing leaks or floods won’t damage it. The experts from Northern Basement Systems got right to work knowing that this was the right fit for Alexei’s finished basement.

Now Alexei can rest easily knowing that her finished basement won’t be susceptible to a little water damage. With the help of ThermalDry Tiles, Matt Clark’s Northern Basement Systems can turn any moldy, rotten, foul-smelling basement floor into a warm, beautiful one.

Water in the Basement Diverted in Lincoln, NH

The customers in Lincoln, NH have a wonderful home in the White Mountains.  Unfortunately, they also had a lot of water runoff which made their basement get a lot of water in it. They also had concerns regarding the stairs leading into the basement.  The concrete was sagging, making it unsafe to use.  Tired of dealing with the water and stairs they contacted the experts at Matt Clark's Northern Basement System(1800-DRY-TIME).  The specialist at Northern Basements looked their situation, through a variety of vigorous and precise tests, and came to the following conclusions. 

1. Install WaterGuard sub-floor drainage system and install WaterGuard Port for access to the system.

2. Install TrenchDrain allowing water from stairs to flow into the Water Guard.

3. Install inside and outside discharge. 

4. Install SmartJack supports to support the floor joist system above for the stairs.   

5. Fix the wall crack with FlexiSpan crack repair system and route to Waterguard drainage. 

6. Install TripleSafe pump system with twin liner, 1/3 hp cast iron primary AC pump, 1/2 hp cast iron AC back-up pump, and UltraSump battery back-up pumping system with charging/control box with alarm, and 120 amp sealed maintenance free battery. Includes 3 CleanPump stands, airtight lid with an airtight floor drain, and WaterWatch alarm system.     

7. Install IceGuard to prevent floods from clogged or frozen discharge line


After completing the installation of the Water Guard, TripleSafe Pump, Flexi Span, and the Ice Guard our customers in Lincoln, NH now has a nice dry basement.  With the Smart Jacks now in place and supporting the stairs they also are worry-free when they use their stairs.

Muddy Water in Lyme, NH Basement

The homeowners in Lyme, New Hampshire was fed up with a water issue in the basement.  They purchased the home three years ago and for three years water had seeped into the basement.  The water would start to come into the basement around spring time and wouldn't even start to dry out until August.  This made it a huge hassle for them.  They couldn't even use the big basement space for storage with out having things on raised platforms.   

 Tired of not being able to use their space they contacted Matt Clark's Northern Basement [email protected]  Matt sent out of his System Design Specialist for the customers FREE ESTIMATE.  After doing the inspection the conclusion was made the best way to keep the customers basement permanently dry was to install a few different products. 

 First Northern Basement Systems installed a CleanSpace Wall System.   The CleanSpace Wall System uses a thick (20mil) white poly sheet material to completely cover basement foundation walls. CleanSpace is installed by fastening the material to the rim joist atop the foundation wall, and by installing press-fit plastic fasteners into the masonry.  As part of your waterproofing system, it creates an effective moisture and vapor barrier. The wall covering forces all wall seepage and moisture to flow into your perimeter drain system. The white poly surface eliminates the need to paint basement walls, providing a bright, stain-resistant finish that never needs repainting or maintenance.  Next, WaterGuard was installed around the perimeter of the basement.  WaterGuard effectively captures wall and floor seepage before it reaches your basement floor. When WaterGuard is installed together with our sump pump system, your basement has complete protection. Water enters the system via inlet holes and flows through the drainage pipe to sump pump. Finally a SuperSump Plus was installed to pump out any water in the WaterGuard.  The SuperSump has a premium plastic sump liner is the attractive alternative to an open sump pit. Perforations in the liner capture ground water, and a larger opening connects to the interior drainage system. The liner's airtight lid keeps out pests and debris, while also eliminating the safety hazard of an open sump pit.  It has a WaterWatch Alarm in case of a power outage, tripped circuit breaker or other malfunction shuts down your sump pump, this alarm will sound when water level rises above the sump pump intake. It has a Zoeller cast-iron, 1/3 HP pump where as inexpensive sump pumps with plastic housings are prone to overheating and burnout. All Basement Systems sump pumps are equipped with powerful, top-quality Zoeller sump pumps. The unit installed in our SuperSump is one of the best, capable of pumping up to 2,280 gallons per hour.  The water from the Super Sump will pump out of the house to a discharge line away from the home.  The homeowners now have a permanent big dry space the can enjoy.  No more putting their storage on risers and no more water in their basement.

Extemely Wet Basement in Plymouth, NH

This home had a high water table and water flowing through channels in the basement to a sump pump pit with a broken sump pump. This system makes the basement unusable, muddy, wet, musty, and damp. These homeowners were in search of a better solution for both them and their home. 

Our system design specialist visited the home and suggested several solutions to keep the basement dry and make it more usable. First, our team installed a full perimeter WaterGuard Drainage System to collect and transport the water that is attempting to enter the basement. Next, they installed our most reliable pump, the TripleSafe Sump Pump System to pump the water out of the perimeter drainage. The last part of this full basement waterproofing system was to install a SaniDry Dehumidifier to filter the air and reduce moisture that causes the musty smell and promotes the growth of mold. 

With these systems, this basement will remain dry, much cleaner, and improve the health of the whole home. Call 855-DRY-TIME to see how Northern Basement Systems can help you and your home!

Responsible Basement Waterproofing in North Haverhill, New Hampshire, by Matt Clark's Northern Basement Systems.

When a family in North Haverhill, New Hampshire, added another member to their team, they also needed to remodel the home's basement to accommodate. 

The family started the remodeling process by removing some of the old things in the basement, and it was then that they realized the carpet along the perimeter of the basement was wet.   They continued to remove all of the belongings in the basement, and the more they moved out, the more areas of wet carpet they found.

Dumbfounded by all of the wet areas in the basement, a decision was made to contact the basement waterproofing experts at Matt Clark's Northern Basement Systems.

Northern Basement Systems sent out a System Design Technician to give the homeowners a free estimate with a permanent solution to their water issue.

During the inspection, the Technician found multiple areas where water was entering the basement of the home.  After the inspection, a custom-designed waterproofing plan was proposed to address each area of concern in the basement.  

The homeowners were overwhelmingly pleased with the proposal, moved forward with the project right away, and now enjoy a newly remodeled and dry basement.
