"I am very pleased with the work that was done on my home. Palm construction took on two renovations projects at my house. Other companies weren’t willing to entertain the simultaneous projects. They were even able to start ahead of schedule. My bathroom fixtures were moved around to function better, give me more space, and the space was fully renovated. I am in love with the tile work that they did. In my kitchen they were able to change the layout, to give me the open concept I wanted. I was able to switch from electric to a gas range and the cabinetry that was installed is beautiful/high quality. The entire process was virtually stress free with the communications and updates I was given. All the timelines were met and exceeded. I would highly recommend Palm construction for any home project."

"Ray and Jacob came right out, quickly diagnosed my problem, and did exactly what they needed to fix it permanently. Super competent and really nice guys (Go Seahawks!). Ray also did a full inspection of my crawl space and attic for free as he knew I was planning to put the house on the market. Ray is certified for both mold and pest control and does not mind getting dirty to do a thorough inspection. I would give ten stars if I could!"

FAQs for radon gas abatement projects in Federal Way, 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.
