Homeowner in Princeton Junction saw uneven slabs on her concrete patio. Due to the rarity of the concrete, replacing was not an option. Also due to the ornate details, the customer wanted to avoid mudjacking since it would ruin the look of her patio. With PolyLEVEL, the concrete leveling was done in only one day, could be walked on almost immediately, and looks great!

Concrete is cold and porous which means that it was letting moisture and cold air into this crawl space. The cold air was causing cold winter drafts throughout the first floor of the home. Quality 1st Basement Systems installed a crawl space encapsulation system to seal off the space from the cold concrete floor. Under the CleanSpace crawl space encapsulation system lies SilverGlo crawl space insulation to further improve the temperature of the crawl space. This home is now healthier and warmer...and costs less to heat and cool!

Basement Waterproofing & Crawl Space Repair

Basements and crawl spaces consistently have issues with water, mold and rot. To prevent these problems from occurring in the future we install a patented interior drainage system. Water and moisture that enters the basement is captured, controlled and safely removed via the basement drain before you ever notice it. The drainage system also works as part of crawl space encapsulation. 

We Provide:
  • Basement Waterproofing
  • Crawl Space Encapsulation
  • Exclusive, Patented Products
  • Humidity Control
You Receive:
  • Permanently Dry Basement
  • Clean Protected Crawlspace
  • Protection against Mold
  • Improved Home Value

We also fix basement leaks with permanent basement leak repair. With our system in place there is no need to fear basement flooding. We want your basement to be safe for years so our work comes with a transferable lifetime dry-basement warranty. 

Foundation Repair & Concrete Leveling

Whatever the issue we are the trusted foundation repair contractor. Our foundation repair experts will visit your home, identify the issue and recommend the right solution. We provide permanent foundation repairs using non-invasive methods. There is no need to tear up your entire yard to fix the foundation.

Repairs for:
  • Wall Cracks

We Use:

Deepest drop is approx. 3 inches along where the garage floor meets the house and runs pretty evenly along the entire length of the floor (22.5 feet).
