Job Stories From Nashua, NH
Heavy Rainstorm Puts Nashua Homeowners Basement in Jeopardy

An unkempt and neglected basement can lead to devastating problems in the future. Unfortunately Nashua, NH homeowner Stephani M. discovered after a heavy rainstorm that her basement was a breeding ground for moisture and mold.  Looking for a solution, Stephani called none other than Northeast Basement Systems after seeing an advertisement in her local newspaper.  

Not long after, Stephani was met by Northeast sales representative and basement specialist Tom Armano. Tom Armano has been representing Northeast since 2003 and has diagnosed hundreds of basements.  Stephani explained her situation to Tom and took Tom down to inspect the basement.  After a careful yet thorough evaluation, Tom determined that the devastation was linked to the perimeter of the foundation.  He found that ground water was seeping through the walls and with nothing to stop it, it would continue until the basement was flooded.  To solve this problem, Tom recommended installing the WaterGuard Interior Drainage System.  This waterproofing would be installed along the perimeter of the basement, catching all incoming water from the foundation and diverting it safely away from the foundation.  After explaining to Stephani the installation process and how the product works, he called in Aaron Rice and his production team to install it.  

In a little under a day, Stephani had a basement that was ready to handle heavy rainstorms, would no longer flood, and a mindset that is now stress free- all thanks to the professionals at Northeast Basement Systems.

TripleSafe Dries Up Nashua Homeowners Basement

Steve. H is a homeowner who is passionate about his house.  Therefore when he found his crawl space was taking in excessive moisture he immediately bought a top of the line TripleSafe Sump Pump to eliminate the problem.  Yet, when he found that a ongoing problem was still occurring, Steve knew he needed help and called on the professionals at Northeast Basement Systems to help him out.

Tom Amano, a sales representative and waterproofing specialist for Northeast met Steve at his Nashua home to take a look at his crawl space.  When Tony inspected the crawl space he found that although the TripleSump Pump was installed it had no way to drain water on the other side of the crawl space. Luckily for Steve, Tony knew exactly what to do to fix his problem.  Tom recommended that a WaterGuard Drainage System be installed along the perimeter of the crawl space; this drainage system will direct all the incoming water toward the sump pump.  In combination with this a TripleSafe liner was installed along the ground of the crawl space.  This speciality liner is made so that water will not seep into the confines of the crawl space all while directing the water toward the sump pump.

Steve loved the recommendations and thought this would be the best course of action.  Upon agreeing with the recommendations, primary foreman Aaron Rice was brought out with his production team to install the necessary products.  In a little under one day, Aaron and his team installed the products and were happy to hear that the following week the products were working perfectly.

Cinder block foundation, 1950s house. Part of the basement where the water heater, laundry, and HVAC system are set up is a bit lower than the other half. We get a bit of water that seeps in under the old tile floor once or twice a year. Not a huge problem but I'd like to look into a waterproofing project to allow us to use the space more efficiently.

My house was built over a creek :( It hasn't been an issue (meaning that the sump well/pump kept the basement dry) until last year. And now, it's like every time there's a "gulley washer" or several days of rain, the water comes in. I'm hoping for a reasonably affordable, long-term solution.

Hi, we are having a problem with an old basement window where during the spring thaw we had water seeping in through it into the basement. We would like to see what options we have such as replacement, adding a window well or even removing the window and closing in the wall space with cement.
