Job Stories From Merrimack County, NH
Basement waterproofing in Franklin, New Hampshire.

In Franklin, New Hampshire, a homeowner was going through the process of finishing off the basement of the home.  The homeowner knew one major issue needed attention before any of the finished work could begin.  A large amount of water would creep into the basement when it rained and continued to seep in days after. 

Being in the construction business, the homeowner knew exactly with whom they would hire to turn the wet, nasty basement into a dry, healthy, useable space.  A phone call was made to the basement waterproofing experts at Matt Clark's Northern Basement Systems to set up a free estimate. 

A system design technician did a thorough inspection of the basement, addressed where the water was entering and designed a custom system to make sure the basement would stay dry, even during a heavy rainstorm. 

A team of highly trained and certified professional installers started installing the custom system.  First, the perimeter of the basement is jack-hammered, and a trench is dug for the placement of water guard drainage. 

Next, a full perimeter drainage system is set in place and surrounded by crushed stone. 

After the water guard drainage system has been installed, it is tied into a Triple Safe Sump Pump.  The Triple Safe has three separate pumps, the primary, a cast-iron Zoeller ⅓ horsepower sump pump set at the lowest level. The second, more powerful Zoeller ½ hp pump set a bit higher in the liner and will handle extra water and serve as a backup.  The third pump will turn on in the case of a power outage; our UltraSump battery backup sump pump will pump 11,500 gallons or more on a fully charged battery.

The Triple Safe will pump out the water via a discharge line that will go through an Ice Guard System and send the water away from the foundation of the home.

To finalize the custom waterproofing design, a state-of-the-art Sedona SaniDry dehumidifier was added to the system.  This will make sure the basement of the home maintains a perfect 55% humidity and is an EnergyStar product.

The owner of the home now can move forward with finishing the basement of the home. 

We checked up with the homeowner a few weeks later to see how his finish work was going and being the experienced carpenter he is, a very cool cabinet was constructed to house the Triple Safe sump pump.

Turning a wet, nasty basement into a clean, dry space in Contoocook, New Hampshire.

Looking to put their home on the market, a family in Contoocook, New Hampshire, called Matt Clark's Northern Basement Systems, after a reference from their real estate agent.  The real estate agent had seen previously sold homes with similar wet basement issues and had clients that worked with Northern Basement Systems to accomplish a dry basement. 

After a free estimate, a custom-designed waterproofing plan, using patent waterproofing products, was installed, ensuring the home's basement will remain dry.  The house is now ready to hit the market and for new owners to enjoy years of a clean, dry useable space.

Turning a wet basement dry in Henniker, New Hampshire, by Matt Clark's Northern Basement Systems.

In Henniker, New Hampshire, a customer who inherited this home recently had done their first walk-through of the house with a general contractor.  With already owning a home, the original owner's priority was to fix the house up and sell it.  The general contractor took the new owner throughout the entire building, pointing out things that would need to be fixed before the house could be listed on the market.  

One of the contractor's major issues was a large amount of water entering the basement.  He pointed out different watermarks on the basement walls, indicating high water levels throughout the home's history.  Fortunately for this homeowner, the hired general contractor had worked with Matt Clark's Northern Basement Systems in the past. 

With a great recommendation from the general contractor, it was easy for the homeowner to move forward with a proposed custom-designed waterproofing system from Matt Clark's Northern Basement Systems.  The custom-designed waterproofing system will ensure the basement will remain dry for years to come and make it an easy sale for their real estate agent.
