New York's Basement & Foundation Contractor

For the past 25 years Quality 1st has been New York's trusted basement & foundation company. We are known for the quality of our work and the quality of the exclusive patented products we use. We are your trusted partner for fixing the basement, crawl space and foundation of your home. 

Basement Waterproofing & Crawl Space Repair

Basement and crawl spaces are well known for water and mold issues. We prevent these issues from happening in your home by installing patented interior drainage systems which collect any intruding water and remove it before it can become an issue. The system works, you never notice and your basement or crawl space stays dry and protected. 

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 any leaks already present in your basement with patented basement leak repair. With the leaks fixed and a drainage system installed your basement is permanently safe and protected. We even include a transferable lifetime dry-basement warranty. 

Foundation Repair & Concrete Leveling

We fix foundation issues in New York, simple as that. When you give us a call we will send one of our foundation repair experts to your home to provide a free foundation inspection. The expert will explain what was found and the best, non-invasive methods to fix the issue. We can resolve the problem your home is facing without tearing up your yard. 

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 

We also lift and level sunken concrete slabs inside and outside of your home. We inject PolyLEVEL, a polyurethane foam, beneath the concrete slab where it expands filling any gaps and lifting up the sunken slab. PolyLEVEL does not erode or wash away, is much lighter than traditional mudjacking methods and requires much smaller installation holes. Give us a call to learn more or get started.

I have leaking into the basement and wall damage.

I am a potential buyer on a property. Today I performed an inspection and found several issues with the basement: extensive damp, broken sump pump, some black mould, rusting of supporting steel columns. Before signing an "as-is" contract on the property, I would like to get a quote for remediating the damp and an assessment on whether the structure of the steel columns has been affected by the rust.
