"My crawl space was flooded due to a hot water leak, major moisture damage and unfortunately I did not know about Willamette restoration and used another company to dry out crawl space but walls in laundry room and entry had to be tore down and that's when Willamette Restoration came into picture and saved the day. They completed the finish work walls, flooring, countertop, painting, replacing cabinets and I cannot say enough about their professionalism, timely manner in getting the job done. They went above and beyond my expectations and their cost was far less than a quote by another company. If you want excellent workmanship Willamette Restoration should be your company of choice."

"I have heard this company used to be a very solid company for a long time. Apparently things have gone downhill. After I sent the information they needed to obtain a permit for the asbestos removal, I asked to schedule a date to have the work done. I received no reply. Six days later, I sent a followup message, asking if we could schedule a date. Again no reply. I was therefore very surprised to receive a call a few days later, that the workers were already at my condo, on a day when I was out of town, and they couldn't do the work, because there was furniture still in the rooms. Maybe I should have known that I needed to remove the furniture, but I was never told this, either on the phone or in the quote they sent. And in any case, I had no way of knowing what day they were coming, since they didn't reply to my messages. I was given a choice: either they not do the work, and I pay for the workers' wasted travel time (my condo was a 3-hour round trip from their office), or I pay them $450 to move the furniture. No explanation why it would cost $450 to move the furniture from two small bedrooms into an adjacent room, but I basically had no choice. Afterwards, I explained that it was not fair for them to charge me for this furniture removal, when it was their own fault: they never told me the furniture needed to be removed, or even when they were coming. Their response? Pay up. The work itself seems to have been completed well. My issues are with the lack of communication, the surly tone of the office staff, and the extortive practices."

FAQs for radon gas abatement projects in Sandy, 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.
