Cranbury's Basement, Crawl Space & Foundation Contractor

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

Job Stories From Cranbury, NJ
Return to a Drier Basement Entertainment Area in Cranbury, NJ

Homeowner Kerry was very pleased with the livable space she had in her basement.  Her investment afforded her family a nicely-carpeted area to watch television and for the children to play as well as provide some additional storage space.  What Kerry wasn’t aware of was the way that water intrusion could ruin any family’s entertainment zone, even with an existing sump pump and portable dehumidifier.

Kerry expressed her distress and was immediately referred to Quality 1st Basement Systems by a customer who received great satisfaction from work done by them in the past.  Quality 1st sent a waterproofing specialist out to Cranbury, NJ to inspect Kerry’s basement and design a solution.

Project Manager Jesus Alvarez-Sanchez headed a crew to install the WaterGuard System along basement walls to direct any water seepage to the sump pump for discharge.  Additional protection included a SaniDry XP Air System, engineered to both dry and filter the air.  This powerful system was installed to allow the collected water to drain directly to the sump pump pit, leaving Kerry to never need to empty a dehumidifier catch basin bin again!  Kerry was thereafter assured of a continued dry basement where her family could once again enjoy the space!
