A homeowner in Swanzey, New Hampshire, needed help with an ample, wet crawl space.  They reached out to the waterproofing experts at Matt Clark's Northern Basement Systems.  A System Design Specialist inspected the entire crawl space inside and out, then drafted a custom-designed waterproofing system, using patent waterproofing products and a Clean Space Encapsulation System,  to both keep the water out and to control any moisture.  The homeowners can now enjoy a clean, dry, moisture-controlled space.

Job Stories From Swanzey, NH
Basement Waterproofing & Encapsulation in Swanzey, New Hampshire.

An ancient home in Swanzey, New Hampshire, had a nasty unfinished basement with stone walls.  The basement was a constant nightmare for the homeowners.  During the transition of the winter to spring seasons, a good amount of water would enter through the stone walls and floors.  The homeowner decided to have the professionals at Matt Clark's Northern Basement Systems remediate the situation and make sure water in the basement would be a thing of the past.

Matt's team of responsible, highly trained certified installers installed a Full perimeter water guard system, a Clean Space Wall System, a Trench Drain, and a Triple Safe Sump Pump, with an exterior Ice Guard System.  

The once nasty, wet basement is now a clean, dry, useable space, ready for the homeowners to enjoy.

I am looking for an estimate to have a sump pump system installed in the basement. Thank you, Ed
Project Location: Swanzey, NH
Our basement is seeping. We have a block foundation and poured floor. It looks as if the entire first row of blocks is seeping. We have been cleaning up water for the last week. We understand that we have to try and deal with it until it's done but something has to be done in the future. We have a finished room that is now ruined. It's not a foot of water but we are constantly using the shop vac & squeegee. Assuming it will need to be dug up and sealed from outside, but looking for professional opinion and quotes. Thank you for your time-Cally
