Customers say: Quick response

"Ted Riddick did an excellent job of performing a mold test in our basement, at the buyers request. I was very leary at first, because we recently cleaned the carpets and were concerned and/or confused that mold could be in our basement. We certainly would have known if we had mold in our basement or water coming causing a mold situation. Needless to say no mold was found, and my worries were alleviated. Mr. Riddick is a seasoned inspector, with a deep knowledge all areas of home inspections. He was professional, kind, did a great job."

"Mark did great work and made the radon abatement system blend well with the house. The office response time was slower than I would have liked, but the price and quality of work was worth the wait. All of the people I interfaced with were extremely helpful and nice. I would highly recommend this company."

"Buying a home is stressful process itâ s very hard to find people you can trust today. The best part of this experience was the home inspection. Jared and the inspectors were easy and helpful from the start. They did a fantastic job of helping and explaining things to me. I price shopped before hand and talked to a few other companies and decided to go with the inspectors and do not regret it. Top notch work from top notch people! Do not hesitate to do business I know I will call them again!"

"Things went well. We had a poor sales experience due to a previous salesperson that did not fully disclose the situation I would experience, however Floodbusters did make the situation right and warrantied the product to ensure that my experience moving forward was the best it could be given the complexity of my basement situation. They continue to work with me and believe me if you have any situation like I do in regards to Iron Ore and the devastation it delivers to your waterproofing system, this crew through my experience is the team now to hire."

Radon Detection and Reduction questions, answered by experts

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

Installation typically takes 1-2 days, depending on the system and property layout.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
