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

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 Andover, NJ
Basement Waterproofing in Hopatcong, NJ

A homeowner living in Hopatcong, NJ became concerned for their basement after noticing water seeping through the floors of their basement. They contacted Quality 1st Basement Systems and scheduled an appointment for an estimate. 

We provided a thorough inspection of the basement and recommended the basement waterproofing system as the best solution. The main components of the basement waterproofing include the WaterGuard French Drain and TripleSafe Sump Pump System. With these systems combined, the basement will stay protected against water intrusion.

A few weeks later, our crew arrived at the home and waterproofed the basement. Since the installation, the homeowner has not experienced any other water issues in their home!

Concrete Sidewalk Repair in Byram Township, NJ

This homeowner in Byram Township, New Jersey noticed their sidewalk was sinking almost 2 inches and cracking. This occurs when concrete is poured over poorly compacted soil. Over time, this soil settles and creates voids in the soil underneath the concrete. If this goes without a repair, this sidewalk will become a tripping hazard, and someone could severely injure themselves.

The homeowner knew this was a problem and they wanted it solved. They contacted Quality 1st Basement Systems and our customer service representative booked them an appointment with our System Design Specialist, Jack Huber. Jack provided a thorough inspection of the sidewalk and suggested they use polyurethane foam to lift and level the concrete. 

A few days later, our foreman Ramon Romero arrived at the job site and began installing the PolyLevel Injection System. This is done by drilling small, penny-sized holes into the concrete and injecting the polylevel into the soil underneath the concrete. This process is repeated until the slab is brought to a level position. PolyLevel is a lightweight and environmentally friendly solution that will not add weight to the existing soil. This is the best solution to repair sinking concrete.

Within 20 minutes the concrete was brought to a level position and the homeowner was happy with the results. They were able to safely walk on their sidewalk without worrying about tripping.
