Moisture Barrier Installation in Maspeth, NY Moisture Barrier Installation in Maspeth, NY

A homeowner in Maspeth, NY was concerned about their crawlspace after noticing dampness and moisture throughout the area. Our System Design Specialist, Javier Romero, fully inspected the crawlspace, and suggested our CleanSpace Moisture Barrier would be the perfect solution. Our CleanSpace Barrier provides a clean and bright look for the crawlspace, and prevents moisture and humidity from passing through. Our foreman, Wilver Cardoza, and his crew installed the CleanSpace along the walls and floor of the crawl space to seal the area and protect it.

Maspeth's Basement, Crawl Space & Foundation Contractor

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

Job Stories From Maspeth, NY
Water Seepage Through Large Cracks In Basement, Maspeth, NJ

A homeowner living in Maspeth, NJ noticed small foundation cracks on the outside of their home. Upon further inspections, water had begun to seep through the foundation walls into their basement. Looking for a solution to their problem, they headed straight to the internet where they discovered Quality 1st Basement Systems and decided to contact them for a free estimate.

System Design Specialist, Bob Peters, did a full inspection of the basement and provided a solution that would best solve their problem. Bob recommended FlexiSpan and a SuperSump Pump to prevent further water intrusion and keep the basement dry. The crew installed FlexiSpan inside the small foundation cracks. FlaxiSpan is a 100% waterproof seal that stays bonded with wall movement, and seals the crack permanently -- warrantied! 

After the crack was sealed, the crew installed a SuperSump pump to keep the basement dry. Both products reassured the homeowner that their basement would stay completely dry through any future rainstorm, leaving the homeowner very satisfied and of course relieved.
