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.

Specializing in water damage mitigation, fire and smoke damage, mold removal, mold testing, indoor air quality testing, air duct cleaning and dryer vent cleaning for the residential, commercial and industrial markets. We also specialize in repairs, rebuilding, remodeling after disasters. We work well with all insurance carriers to get your home or business back to better than before the disaster!

"Sansara did a fantastic job in restoring our lower level bathroom and family room after a frozen/busted water pipe flooded the area. Jamie and his crew were on the scene shortly after the water mitigation work was completed by Sansara’s mitigation team. The rebuild process was quick and the carpentry work was professional. The damaged areas were restored beautifully and looks like nothing ever happened. I highly recommend Sansara if you ever need mitigation and rebuild or, just want to remodel."

Radon Detection and Reduction questions, answered by experts

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.

To determine whether you have radon in your home, you must run a test. Radon gas has no odor or color, so you won’t notice a concentration of radon. You could purchase a DIY test at a local hardware store, but it may not deliver completely trustworthy results. The best way to test and receive accurate results is to hire a local radon detection specialist.
