Middlesex's Basement, Crawl Space & Foundation Contractor

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

News & Events From from Middlesex
Your basement can provide valuable “healthy” space. In this day and age, we all have “stuff” in our lives. How many times have you driven past one of those huge storage facilities, only to think, “Wow, wouldn’t it be great to have extra space?” We all have the overflow of “stuff” in our lives to make living more comfortable; we just tend to crowd our livable space with all of it. ...

We got some damages from Ida and we are looking for assistance for a few projects. First, is checking to see if there are damages/cracks to basement wall/floors. Second is replacing damaged drywall (would like to just remove bottom portion to install waterproof option). Lastly, is refinishing the floors with tiles (it was laminated in the past and under the laminate, there are still tiles). Drywall hasn't been removed yet, but I'm looking to move ahead in removing the bottom portion. If someone can let me know how many feet/inches the drywall needs to be removed from the bottom, I can start getting that complete to allow for a better estimate of the other repairs. Please feel free to text or email if that'll work better. Looking forward to hearing back. Thank you.

Hello, My basement is not finished. I literally only have the framing up. No sheet rock, and some insulation. The basement looks to have had water damage at one point. Today 4/2/2020 I have a smell that is coming from the basement and it feels like its the ground from outside smell seeping through my basement walls. I would like to have someone come and give me a free estimate on what is the problem and how to resolve it. What are my options to fixing this issue once and for all.

We have an enclosed front porch that many years ago, long before we bought the house, was an open porch. The crawl space underneath has a dirt floor. There is no foundation all the way around, only corner footings. It is partially vented. There is no access from inside the basement, only a wooden "hatch" underneath the front steps that you crawl through. We have a problem with animals getting in there, chewing up the HVAC flex ducts and nesting, as well as dampness and the enclosed porch being cold. That's is a summary of the issues.
Project Location: Middlesex, NJ
After the recent flooding, I noticed mold growth in the crawl space. Insulation is washed away. The crawl space ceiling is very wet. I'd appreciate contacting me at your earliest convenience.

We are looking to get an idea on how much it will cost to improve our basement. Our house is 90+ years old, and we have seeping issues, and crumbling around the edges of the block. Thanks, Stephanie
