Kennett Square's Basement, Crawl Space & Foundation Contractor

For over 25 years, Quality 1st Basement Systems has been the trusted basement & foundation company of Kennett Square. 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
  • EverBrace® Wall Repair System
  • 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 Kennett Square, PA
Foundation Repair in Kennett Square, PA

In Kennett Square, PA, a homeowner started noticing worrying signs around their home — new nail pops and some troubling floor creaks. Although nothing overly alarming seemed visible in their mostly finished basement, a small crack spotted in one corner of the unfinished part had them on edge. We sent out a System Design Specialist from our Sales Team who performed a thorough inspection. Yes, those nail pops and creaking floors were minor, yet they were evidence of an underlying issue that could not be ignored. The type of concern when missed could spiral into more significant, more costly damages down the line — something we aim to help homeowners prevent. Understanding the homeowner’s worry, our specialist recommended the installation of Push Piers, a dependable and minimal impact solution tailored to ensure the foundation's integrity.

Basement Waterproofing in Kennett Square, PA

At Quality 1st, we recently had the opportunity to help a homeowner in Kennett Square, PA, who was struggling with an issue many homeowners fear: moisture in their basement. After contacting our Customer Care team, we quickly arranged for a System Design Specialist to visit their home. Upon thorough inspection, our specialist uncovered that the primary culprits were ineffective water drainage and a lack of a reliable sump pump system. Armed with this knowledge, we proposed a tailor-made solution to address these issues head-on: the installation of our WaterGuard interior drainage system and a TripleSafe Sump Pump. The WaterGuard system is ingeniously designed to intercept water at the perimeter of the basement, directing it efficiently to the TripleSafe Sump Pump. 

Basement Waterproofing in Kennett Square, PA

Not long ago, a new homeowner in Kennett Square, PA, encountered a daunting challenge. They'd just moved into a new home, only to discover that the basement, essentially a gravel pit, was far from the ideal space they'd imagined. After contacting our Customer Care team, a System Design Specialist from Quality 1st promptly visited their home. Upon thorough inspection, we prescribed a comprehensive solution tailored to both address the immediate concerns and prevent future problems. We recommended the installation of our proven products: WaterGuard for superior drainage, a SuperSump sump pump to handle the meanest of rains, CleanSpace liner for wall protection against humidity and pests, and a SaniDry Sedona to keep the air dry and healthy, effectively targeting the heart of their basement issues.
