Quality 1st Basement Systems fixed this sinking concrete slab permanently. The crew injected PolyLevel underneath the concrete. Once the PolyLevel expanded, it lifted the concrete up to a level position. Now this Stewartsville, NJ property is safer with PolyLevel.

The front porch of this Greenwich, NJ family home had settled, creating a 5 inch gap between the siding and the concrete. The homeowners were very concerned since it happened rather quickly and so they wanted to get it fixed right away. System Design Specialist, Ken Peare, inspected the entire wrap around porch and measured almost 3 inches of settled concrete. He recommended PolyLevel to be injected underneath the slab, where it would expand and harden, raising it back to level. The homeowners were amazed that after 15 minutes of the job completion, they were able to use their porch.

A homeowner in Stewartsville, New Jersey had their floors sloping towards the middle of their house and there was also water in their basement. The homeowner contacted Quality 1st for a free estimate and our System Design Specialist inspected the basement. SmartJacks were installed to help support the home and provide stability. SmartJacks are installed by attached steel support beams to the floor joists and a sturdy base at the floor. SmartJacks can easily be adjusted at any point if the home requires it. Now this home is supported and the homeowners do not have to worry about their home being unstable.

Stewartsville's Basement, Crawl Space & Foundation Contractor

For over 25 years, Quality 1st Basement Systems has been the trusted basement & foundation company of Stewartsville. 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
  • Egress Windows
You Receive:
  • Permanently Dry Basement
  • Clean Protected Crawlspace
  • Protection against Mold
  • Improved Home Value
  • Less Leaks & Better Energy Efficiency

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
  • EverBrace® Wall Repair System
  • 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.
