"I contacted them for minor moss removal and treatment. The owner came out to look it over and told me I didn't really need removal, that treating it twice would take care of the problem without removing any granules from the shingles. He showed up a few days later and treated it. Although I don't see any remaining moss, I am going to follow his recommendation and have him do it again in the fall. The price was quite reasonable and the people were nice to deal with."

"We hired Lex Construction for siding replacement and exterior paint, which included replacing two windows, some general construction to repair bulges in the studs and some roofing/fascia board repair. Of all the companies we had bid, we really felt like Mike listened to our vision and didn’t feel the need to rearrange it to his preference. He also gave us some great suggestions and recommendations, some which we decided to go ahead with and some not. The price was really reasonable, and we ended up adding the front deck replacement mid-project. Both Mike and Troy were responsive and courteous, and did a great job, as well as the contractors that covered the roofing and paint. A few minor details were missed between what we discussed and what they executed, but nothing major. Overall we were really happy with them, and plan to use them again for additional projects we have in mind. We highly recommend them for your next project!"

"Chris came out to do the initial assessment. I had been reading about crawlspace treatments, so I had questions about encapsulation and 16 mil vapor barrier. Rather than upselling, he told me that; 1. The insulation I had was hanging down all over the place, meaning it wasn't accomplishing anything, so he recommended removing it. He said that replacing it wouldn't help much and would not be cost effective. 2. Since I had no water issues the 16 mil vapor barrier wouldn't be of any value to me and the standard 6 mil material would do just fine for about $1000 less. I had asked for the right solution, not the cheapest, so I very much appreciate his recommendations. The actual job went off as scheduled with no problems. They sent me pictures, which was great, since I don't ever intend to go under there again. I also had a number of interactions with the office manager, Julie, and found her to be pleasant and responsive every time."

FAQs for radon gas abatement projects in Sherwood, OR

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.
