Job Stories From Belknap County, NH
Two Wet Crawl Spaces Repaired Underneath One Laconia, NH Home

David R. of Laconia, NH faced a nightmare twice the size of other homeowners. Both crawl spaces beneath his home had wet dirt floors. His old access well, which had rotted and corroded over time, probably contributed to water reaching below. David wanted a professional opinion on what to do to fix his crawl spaces. Researching products that would fix his problem brought David to Matt Clark’s Northern Basement Systems’ website. He called to discuss what the company could do for him and set up a free, no-obligation estimate.

 A SmartSump sump pump installed in one crawl space and a SmartDrain in the other would help expel the excess water. CleanSpace drainage matting and a crawl space liner would also keep the space dry, since the matting transports the water to the drainage system, and the liner seals the interior of the space.

David is happy with the results of the crawl space waterproofing and repair job and has since seen his energy bills decrease dramatically! The homeowner is thankful that he contacted the experts at Matt Clark’s Northern Basement Systems.

Waterproofed Basement Adds Storage Space for Laconia, NH Homeowner

Sue C. of Laconia, NH recognized that her basement was leaky, but she did not feel pressured to have it fixed until she ran out of storage space in the rest of the house. Sue heard of Matt Clark’s Northern Basement Systems and decided to check out their website. After submitting a request for an estimate online, a representative called Sue and set her up with an appointment with a waterproofing expert.

Northern Basement Systems installed a complete waterproofing system, including TrenchDrain channel drains and a WaterGuard XL drainage system. They also installed a SuperSump sump pump and a LawnScape drainage outlet. An IceGuard drainage line device was also added to ensure proper water drainage even if the lines freeze or become clogged. Finally, the team covered the basement with CleanSpace waterproof liner to help protect Sue’s belongings.

Thanks to a job well-done by the team at Matt Clark’s Northern Basement Systems, Sue has peace of mind knowing that damp conditions will never damage the irreplaceable items in her basement!

SaniDry XP Keeps Finished Basement Comfortable in Laconia, NH

Jim and Natalie S. of Laconia, NH had their basement finished a while ago, but the air always seemed to be damp, so they found themselves never really wanting to spend time in their basement. The couple was worried that they may have remodeled their basement for nothing. They decided to contact a basement specialist to inspect their basement and suggest any possible options for repair. A Google search provided the homeowners with a few options of waterproofers in the area, but Matt Clark’s Northern Basement Systems seemed to the best fit for the job. They had numerous certifications and great reviews!

Basement expert Justin Lanfranconi inspected the basement and suggested installing a SaniDry XP dehumidifier to remove moisture from the atmosphere. Rather than installing the system in the finished room itself, where it would be unsightly, the team placed it in the adjacent, unfinished part of the basement. Wall ducts installed in the finished area of the basement connected to the dehumidifier and offered a discreet method for conditioning the environment.

Before contacting Matt Clark’s Northern Basement Systems, Jim and Natalie were not even sure that their problem could be fixed. Not only did the company prove the couple wrong, but the team also outdid itself when they took the basement’s appearance into consideration. Now, space is an enjoyable place to relax on the weekends!

Drain and Sump Pump Installation in Laconia, NH

These homeowners called Northern Basement Systems after their finished basement rug floor started getting very wet. They were concerned about water damage to their belongings and investment in this space. We provided a free estimate and then began the project right away. The team started by cutting the walls and pulling back the carpet to access the bottom wall to install WaterGuard and the TripleSafe Sump Pump systems. After installation, the team framed and sheet rocked around the system and concealed it to return the space to its original condition prior to the water entering the basement. This left the homeowners with a worry-free solution to keep their finished space dry.

Crawl Space Vapor Barrier and Support in Gilford, New Hampshire

Tom of Gilford, New Hampshire was in search of a permanent solution for his dirt crawl space with some water damage. He found Northern Basement Systems online and called to book his FREE ESTIMATE

We then provided Tom with the best solution for his crawl space to ensure that it remained dry, clean, and warm. First, the installation specialists placed 2 adjustable SmartJack Supports to add supplemental support to the home. Next, the installation team laid down CleanSpace Drainage Matting and CleanSpace Liner. This CleanSpace Crawlspace Encapsulation System will keep any debris or water from entering the crawl space area year-round. Next, our team sprayed closed-cell polyurethane foam 3" thick on the perimeter walls. The foam was then painted with intumescent paint to meet fire code regulations. Lastly, the installation team installed a SaniDry Sedona Dehumidifier to improve air quality and reduce humidity. 

With these systems in place, Tom's home is now safer, cleaner, and warmer. Don't wait to fix your basement or crawlspace! Call Northern Basement Systems at 855-DRY-TIME to book your FREE ESTIMATE!

Basement Waterproofing in Belmont, New Hampshire.

A homeowner in Belmont, New Hampshire, sat in the basement of his home.  As the rain grew louder and louder, he knew it was only a matter of time before his old rusty sump pump would fail.  With each load of water that the old pump struggled to pump-out, he thought of how many hours and hours of his life that were wasted cleaning up water in his basement.  You see, by now, that old rusty sump pump has failed, much like it has every time, and this unfortunate homeowner has a basement full of water.  He'll sometimes spend up to five hours cleaning up the mess left behind by the pool of water. 

Well, this time, the homeowner was fed up.  He decided to no longer waste any time cleaning up water, he was going to get this fixed; and fixed the right way.

He made a phone call to a long-time friend, who happened to be in the construction & concrete industry for over 30 years and now owned their own company.  He told his friend what was happening in his basement every time it rained and asked if his company could do the job for him.  The homeowner's friend told him his company did not do such specialized projects, but would highly recommend Matt Clark's Northern Basement Systems.  The friend had used Matt Clark's Northern Basement Systems to waterproof many projects for his company through the years and always had outstanding quality results.

Having a fantastic recommendation, from a close friend, made choosing Matt Clark's Northern Basement Systems a natural and confidant choice for the homeowner in Belmont, New Hampshire.  The homeowner called 855-dry-time and set up a free estimate with a System Design Specialist.

After the inspection, the System Design Specialist goes over a custom waterproofing plan to address the multiple areas of the basement where the water was entering.  

Matt's team of highly trained, certified waterproofers went to work right away to make sure this homeowner would never waste another day of his life cleaning up water in the basement.  First, a Clean Space Wall System goes along the entire perimeter walls of the basement.  Next, a trench dug to install a full perimeter Water Guard Drainage System.  The Clean Space will tie into the Water Guard, doing this allows both the water entering via wall seepage and water entering up through hydrostatic pressure to flow to the newly installed, Triple Safe Sump Pump.  Unlike the old insufficient sump pump, the Triple Safe Sump Pump has three separate pumps.  The Zoeller M53 pumps up to 2,220 gallons per hour, and the Zoeller M98 pumps up to 3,900 gallons per hour.  The third pump is a battery back-up.  This pump will kick on in the event of a power outage and provides owners will nice ease of mind.  The Triple Safe will then pump water out of the basement through discharge lines and discharge away from the basement. 

The homeowner now has a healthy, clean, dry useable basement.  Best of all, anytime it rains, the owner no longer worries about a pool of water to clean up in his basement.

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.

Moving in and Finding a Wet Basement in New Hampton, New Hampshire, with Matt Clark's Northern Basement Systems.

When John F couldn't stand being in California for one more minute, he decided it was time to pack up and move back to his New England roots of beautiful New Hampshire.  John knew his job was able to be performed remotely, and that's exactly what he was going to do.  He had a vision of turning his new basement into a large office, making it easy for him to maximize his workflow and potential.

John purchased his new lakefront home without visiting it, leaning on his home inspector/contractor for inspection and recommendation.  While the home inspector did put in his note that there look to be possible signs of water entering the basement at some point in time, the home inspector noted that the basement was dry upon inspection.  The home inspector gave John the number to Matt Clark's Northern Basement Systems in case water ever started to be a problem.

Well, fast forward to John settling in his new home and being there for the first heavy rain storm of the spring.  Thankfully John hadn't fully remodeled his basement for office use yet because when John went to work in his basement that night, he saw pools of water in different locations.  Luckily for John, most of the water didn't destroy anything but knowing he had big plans to remodel and furnish his basement for work fully, something had to change.

John was delighted that his home inspector had given him the number to a basement waterproofing company.  The following day John called 855-Dry-Time and set up an estimate with one of the Northern Basement System Design Technician.

After a thorough inspection, the System Design Technician went over a custom-designed responsible waterproofing system which would make sure John's basement would stay dry, and he could proceed, worried free, with the remodeling of his basement.

Matt Clark's Northern Basement Systems turned John's wet basement into a dry, useable space.  He could remodel the entire basement for an office for work and hasn't seen a drop of water in his basement since.

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

The heavy rain splash against the living room windows as Patrice, a homeowner in Sanbornton, New Hampshire, anxiously paced his living room.  Patrice knew it would only be a matter of hours before his basement would start to fill with water, and he would sometimes spend the entire night trying to keep up with the water shop vacuuming up.  

Well, after spending most of the night shop vacuuming, but this time not being able to keep up with the water and watching his basement flood, Patrice had enough.  Patrice found a few waterproofing companies but ultimately hired Matt Clark's Northern Basement Systems based on their great reviews, past work, and a recommendation from his cousin, who had work from Northern Basement Systems a few years prior.  

Northern Basement Systems installed a custom-designed waterproofing system consisting of patent waterproofing products specifically designed to make sure water doesn't reenter the home's basement.  

Patrice now can enjoy his dry, clean useable basement, and best of all, he says he no longer gets that uncomfy anxious feeling when the rain starts falling.
