Before After
Water Damaged Georgia, VT Basement Water Damaged Georgia, VT Basement

The homeowner in Georgia, Vermont had experienced water damage in their basement.  The majority of the basement had carpeted floors, which got the worst of it.  They also received damage to the lower parts of their walls, that was drywalled.  The owner contacted Matt Clark's Northern Basement Systems in search of a way to refinish their basement with products geared more to waterproofing and looking good.  Matt's System Design Specialist introduced the family to a couple of different products, that would both look good and withstand the potential of water damage.  Matt's team fixed the lower drywall areas with an Everlast Wall Restoration System and replaced the old wet carpet with brand new Thermal Dry Carpet.  The Everlast Wall Restoration System provides a solution for homeowners who have experienced wet, damaged or moldy walls in their finished basement, and protects against any future damage. This wall system includes metal studs and an inorganic, mold-resistant wall product that replaces the bottom 32" of your home's drywall. An inorganic base molding and decorative chair rail make this an appealing, long-lasting solution.  The ThermalDry Carpeting doesn’t roll out over the floor; it’s manufactured in square tiles that snap together. With ThermalDry carpet tiles, there’s no foam pad to soak up water. Instead, there’s a waterproof plastic base designed with a built-in drainage plane and thermal break. Water drains through ThermalDry carpet rather than soaking in, eliminating worries about mold, mildew and moisture damage.

Job Stories From Grand Isle, VT
Cracked Foundation in Grand Isle, Vermont

Paul contacted Northern Basement Systems because he was concerned about his foundation. There were large cracks in several places and he was worried about the wall falling in. We provided a site inspection and a FREE ESTIMATE with a solution that could alleviate his concerns. 

Our installation specialists installed 5 PowerBraces against the wall that was cracked to stabilize the wall and keep it from bowing, buckling, tilting inwards, or even falling. These PowerBraces are steel I-beams that are secured to the joists above the wall with steel brackets. This system is also easily adjustable, allowing for tightening of the brace to attempt to raise the wall back to its original position. This system doesn't involve any exterior excavation making the install quick and with very little disruption.

With this PowerBrace Foundation Wall Repair System in place, the homeowner no longer has to worry about his foundation or home! If you have concerns about your home's foundation, don't wait! Call 855-DRY-TIME for your FREE ESTIMATE with Northern Basement Systems!
