This homeowner was experiencing some serious problems in their crawl space. Not only were their floors sagging, the crawl space was also accumulating water! Luckily, our System Design Specialist, Jeff, was able to come up with the perfect solution for their problems. Our  Team installed SmartJacks to stabilize the sagging beams, leveling the floor on the first level of the home. We also installed a CleanSpace encapsulation to prevent water and moisture from seeping through the foundation into the crawl space area. The homeowners crawl space is now another dry and healthy space in their home.

Keansburg's Basement Waterproofing, Crawl Space Encapsulation & Foundation Repair Company

For over 25 years, Quality 1st Basement Systems has been the trusted basement waterproofing, crawl space encapsulation, basement finishing, gutter installation, and foundation repair company of Keansburg. Our high-quality work and exclusive access to 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.
