"Perfect. <br /> An estimator came to my 1929-built building to take a look and bid on the removal of the kitchen flooring on 12/10/2015.  He was very helpful, walked through the whole place and offered some suggestions of where asbestos might be lurking.  I decided to treat the multiple stacked layers of linoleum and vinyl floor as if it were asbestos-containing and he wrote me up an estimate.  He also left me with bags and directions for any testing that I wanted to do elsewhere in the space. <br /> Prior to job day I removed cabinets and other floor-sitting items from the kitchen.  They arrived on 1/5/2016, setting up a containment zone in the kitchen and abated the flooring within about 3-4 hours.  After final tests to ensure that the environment was clear of asbestos fiber they ended the job, having removed all waste materials from site.   <br /> We are very pleased with their efficiency, knowledge, price of work, and quality.  They made it quick and easy to safely continue renovating our space. <br />"

"I received my radon results in a timely manner. I did not hire them specifically, (so, I cannot say I would hire them again) the local company contracted them for this service. The home inspector I hired, handled this service for me and included the results in his report."

"We specifically requested Keith Cook as our inspector because he inspected a friend's home and had a high degree of attention to detail. I'm happy to report that he didn't let us down when conducting our inspection. He arrived early and began inspecting the exterior. He climbed onto the roof and even into the attic! He didn't miss a thing...no even loose or missing screws on household fixtures. Keith knows his stuff and takes the time to explain it to you. He's funny and very efficient...our inspection report was emailed less than 8 hrs after completion of the inspection. Additionally, a member of the company called me to report the results of the radon test immediately upon completion. This is an A+ company and Keith rocks!"

FAQs for radon gas abatement projects in Granite Falls, WA

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
