When the homeowner noticed vertical cracks in their basement wall they called Quality 1st to do the job. System Design Specialist, Ken Peare, did a full inspection of the basement to make sure that these cracks were the only cracks in the foundation of the home. Foreman, Melvin Cardoza, installed FlexiSpan into the cracks sealing them to prevent water from coming through. First bead of Sealant is placed inside the crack to stop crack leakage. A FlexiSpan Foam Drain Strip is then placed over  as a second form of protection against water leakage through the first seal, followed by the permanent seal overlay.

Our team installed our CleanSpace Vapor Barrier System along against the walls of this Lambertville, NJ basement to protect against mold and moisture. The Vapor Barrier stops water seepage and moisture creating a dry and healthy space downstairs in the basement.

Concrete slabs sink and settle when the soil beneath it can no loner support the weight. Our concrete lifting and leveling solution known as PolyLevel, provides the concrete with the additional support it needs to prevent future settlement. 

Above, you can see we injected the polyurethane foam underneath the slab, raising back to level.

Lambertville's Basement & Foundation Contractor

Quality 1st Basement Systems has been serving Lambertville residents for over 25 years. We provide you permanent solutions for basements, crawl spaces and foundations. We are known for our quality work and patented basement products. For basement waterproofing, crawl space encapsulation, foundation repair, concrete lifting we are Lambertville's trusted contractor.

Basement Waterproofing & Crawl Space Repair

If you are dealing with flooding, moisture or mold in your basement or crawl space we can solve the problem. We waterproof and protect basements by installing a perimeter drainage system along the interior of the basement. Any water entering is collected and channeled to a high-volume sump pump where it is pumped out and away from your basement.

We also install an energy-efficient dehumidifier designed specifically for the basement. By controlling the relative humidity moisture is controlled and mold is prevented. Our basement work in Lambertville comes with a transferable lifetime dry-basement warranty. 

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

Similar to the basement we also waterproof the crawl space by sealing and encapsulating it with heavy-duty vinyl vapor barrier. If needed a crawl space sump can be installed along with a dehumidifier. Like the basement this controls moisture in the space preventing mold and rot.

If the floor above the crawl space is cold we can add proper insulation to make it more comfortable. Instead of a debris filled nest for mold and racoons your crawl space will be a clean dry area you can use for extra storage space! 

Foundation Repair & Concrete Leveling

If your home is facing structural issues stemming from the foundation we can restore the foundation and prevent future issues. Using warranted foundation repair products we repair the foundation using non-invasive techniques, no torn up fixed foundations. Give us a call to have one of our foundation repair specialists visit your Lambertville home for a free inspection. 1-844-268-0860

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 

For homeowners dealing with sunken concrete slabs we have simple solution, PolyLEVEL. PolyLEVEL is a polyurethane foam that we inject below the sunken concrete slab. The foam quickly expands to fill the empty space and raise the slab back to its original position.

PolyLEVEL is a definite improvement over the mudslurry that most contractors use. Not only is it lighter, but it doesn't wash away, is injected through smaller holes and cures faster.

We have a cement walkway between our house and our neighbors house. It runs right up to the foundation. Last year our basement was dry. Since we had power washing of that area we are now getting water through small cracks where to two meet. a small puddle will form in basest at bas of floor and wall. I am seeing this in more ares now and for the first time I have seen wet walls. We need work done on the outside and maybe work done on the inside. There isa weird drop off crack where the walk way was redone. I believe water is seeping under there causing problems as well. Thanks

We just moved into a new property and the floors on the first floor are sagging in one area. In the basement, there is a clear gap between one joist and the floor boards. hoping to have someone jack-up or replace that joist in order to provide additional support and prevent further sagging.
