This homeowner in Clark, NJ had a damp and wet basement. When it would storm, the rain water would puddle in the basement. Quality 1st Basement Systems installed a full perimeter basement waterproofing system along with a TripleSafe sump pump. The TripleSafe sump pump has three sump pumps in one so that no matter the water levels, the pump will never fail. One of the sump pumps is battery back-up powered so that it will continue to keep the basement dry even during power outages.

A homeowner in Clark, NJ was getting water through his window into his partially finished basement after rainstorms. Quality 1st Basement Systems installed a SunHouse window well enclosure. SunHouse covers up the existing window well. Unlike metal, it will not corrode or grow rusty, so it will withstand the toughest weather. SunHouse window wells look bright and attractive with their bright white trim. The sides are clear, so natural sunlight filters into the basement. Now this basement window no longer leaks and the basement does not get wet during storms.

Sinking Concrete Around Pool in Clark, NJ

A homeowner had contacted Quality 1st Basement Systems when they noticed that the concrete around their pool was settling about an inch. The homeowner could not enjoy their pool as the settled concrete had created several tripping hazards.

Systems Design Specialist, Jeffrey Pitek, suggested Polylevel after examing the concrete near the homeowner's pool. PolyLevel is lightweight and is waterproof, which made it the perfect solution. The Project Manager and his crew injected polylevel into each settled concrete slab raising it back.

Now the homeowner is pleased they can use their pool without worry about tripping hazards.

Clark's Basement, Crawl Space & Foundation Contractor

For over 25 years, Quality 1st Basement Systems has been the trusted basement & foundation company of Clark. 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.
