Colonia's Basement, Crawl Space & Foundation Contractor

For over 25 years, Quality 1st Basements has been the trusted basement & foundation company of Colonia. 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.

Within the past 5 years we have had a number of plumbing issues. I have a concern that even after we had the crawl space "cleaned" that there still needs additional work to do as we occasionally we get a smell throughout the house.

I would like a quote for vapor barrier for crawl spaces. We have 3 under our ranch. we don't walk on it or use it for storage.
Vicinity of Hawthorne Avenue in Colonia
Awful smell from crawl space. Most of the time it smells like something similar to cat urine. When the fan or ac is on the smell is the strongest especially in the kitchen, which is above the crawl space. Also has a humid sense to it. When the fan and AC is off the smell appears and disappears without provocation but is more pronounced in the basement right where the crawl space is located.
