The deck in this South Plainfield, NJ backyard had sinking concrete slabs which created an eyesore and tripping hazards. Quality 1st Basement Systems Foreman, Octavio, injected PolyLEVEL underneath the concrete slabs to lift them back to their original position. PolyLEVEL is lightweight and waterproof, making it the better alternative to mudjacking.

A homeowner living in Plainfield, NJ contacted Quality 1st Basements for a solution to the water they were experiencing in their basement. System Design Specialist, Laura M. went out to meet with the homeowner, inspect the basement and design a permanent solution. 

Laura recommended a full perimeter waterproofing system to prevent future leaks and flooding of the basement. The WaterGuard drainage system would collect the water seepage and direct it straight to the SuperSump pump. Now the basement will stay dry and healthy!

Plainfield's Basement, Crawl Space & Foundation Contractor

For over 25 years, Quality 1st Basement Systems has been the trusted basement & foundation company of Plainfield. Our high quality work and exclusive access to over 28 patented products set us apart in the home improvement industry. When working on basements, crawl spaces and foundations we are the safe choice for your home.

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
  • Bowing Walls
  • Uneven Floors
  • Settling Foundations
  • Uneven Concrete Slabs       
We Use: 
  • Wall Anchors
  • I-Beam Wall Braces
  • Foundation & Slab Piers
  • Crawl Space Jack Posts
  • PolyLEVEL 

Along with general foundation problems we also fix sunken concrete slabs using PolyLEVEL. PolyLEVEL is an expansive polyurethane foam that fills in the gaps beneath the sunken concrete and lifts it back up to a level position. It also does not erode or wash away. If you are looking for the right foundation repair company, you found it. Let's get started.

Job Stories From Plainfield, NJ
Crawl Space Water Profing in North Plainfield NJ

Antoine from North Plainfield NJ needed to have an inspection done in his crawl space. He was having moisture and water issues and decided to have Quality 1st Basement Systems come out to his home to provide him with a free on-site estimate. Mario, one of our design specialists, provided Antoine a quote and installation was completed recently. He had our Clean Space vapor barrier and drainage matting installed, which is part of our encapsulation system, and a SaniDry Sedona Dehumidifier, which will keep the crawl space humidity at a low percentage.
