Quacker's Waterproofing & Basement Repair, LLC
Quacker's Waterproofing & Basement Repair, LLC
Quacker's Waterproofing & Basement Repair has been family owned and operated since 2001. No subcontractors or commissioned sales people are used. Cost is determined by the job. Due to our experience installing waterproofing systems, fixing foundations as well as our Radon testing and mitigation experience gives us the skill sets to install Radon resistance waterproofing systems. Most of our competitors don't have this combination of skill sets there before may waterproofing systems that are installed can potentially contribute to elevated radon levels in their customer's home. We can solve most foundation/basement problems as well as improve our clients indoor air quality which is a very high priority for us. It is our commitment and responsibility to insure our customers have healthy homes and we are do nothing to compromise that. We are not tied to or required to use any propriety systems or products that many companies are vested in. We use the systems and products that we feel provide the best solution for our client's problem. For customers who want a more finished look than a normal crack injection, we offer a special surface seal that can be removed from the surface of the wall after a crack is injected leaving only the repaired crack line visible. We can also paint the basement walls to make both crack repairs and carbon fiber repairs much less visible. In addition to radon testing and mitigation we really are positioned to be a one stop shop. There are several brand name products and systems we use on a regular basis. "Fortress Stabilization" carbon fiber wall stabilization products, "Stabilizer" top and bottom adjustable I-beam brackets used with vertical I-beams for wall stabilization, and "Kryton" crystalline waterproofing products used when crack injection and other waterproofing methods will not be effective, We also use "RadonAway" radon mitigation fans for all of our radon mitigation system installation. Due to our experience repairing foundation wall cracks many times we can provide an accurate repair price over the phone with just a good discription from the client or a clear picture of the crack.
"it went fine, he came to see the problem & a week later he fixed it. water is no longer coming in."
