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

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.

Job Stories From Princeton Junction, NJ
Crawl Space Sealed in Princeton Junction, NJ

A homeowner in Princeton Junction, New Jersey noticed their crawl space was attracting water and moisture. This happens because the poorly backfilled soil around the foundation becomes saturated during heavy rainfall. This saturated soil creates hydrostatic pressure, which pushes water to seep through the walls and floors in the crawl space. This can have many negative effects such as pests, dust mites, musty smells, damp carpets, increased energy bills, and even mold growth.

The homeowner contacted Quality 1st Basement Systems and our System Design Specialist, Javier Romero, was able to provide an inspection and help them find a solution to this issue. Upon his inspection, Javier noticed the moisture in the crawl space and he suggested they encapsulate the crawl space.

Our foreman arrived on the site and began the installation process of the CleanSpace Vapor Barrier System. This system is thick and durable like a pool liner and will seal the crawl space from the earth's elements. This process is done by removing dirt and debris from the crawl space, leveling uneven surfaces, and then carefully fitting the system and holding it in place with drilled-in fasteners and spikes. 

When the job was complete, the homeowner was pleased with the professionalism they observed on the job, and with the outcome. Now, they have a usable space for storage that will be protected from water and moisture.
