"Very satisfied with the whole process. Gerald did an excellent job. Arrived punctually and observed COVID protocols. Explained clearly what he was going to do and how. Showed us preliminary findings, and obtained our permission to take samples for lab testing. We felt he listened to, and responded to, our concerns. Overall a very professional experience.

"Exceptionally knowledgeable professionals with a service mindset. My office and storage building was flooded from a burst pipe last winter (2021/2022). I called up Affordable Restoration and they helped me through the whole process. They also referred me to a fantastic public adjuster who took care of the whole claim for me. I was impressed on how knowledgeable the Affordable Restoration crew was on not only the flood aspect but also on how to work best with my insurance company. They took the time to educate me throughout the whole process on water, mold, mitigation, restoration and the claim process. After my initial meeting with them, I felt like I was an expert on these topics. This gave me a lot of confidence in working with my insurance claim. It was a breath of fresh air to deal with a contractor that actually cares about you and takes the time to listen and address all of your concerns. Their crews did a great job. They always showed up on time, constantly monitored the site conditions and left the site cleaner than they found it. I'm confident that my building was restored properly and is safe for future use. I would highly recommend working with them."

We are a drug free company with random drug testing. We have been in business since 1992. We have 6 employees to serve you. We do use sub contractors when we need to. Our sub contractors have been with us for years and they do quality work. We are fully licensed, bonded and insured. All our trucks and company vehicles are fully insured. As for our employees and sub contractors we are named second on their policies. This means if their insurance is cancelled for any reason we are notify and we do not let the employee work or sub work for us till it is all taken care of. We only charge for estimate when they are for large jobs. This fee is only charged if we do not do all the work. It takes a lot of time and footwork getting a large job estimate completed. We offer all repairs for insurance claims. We will work directly with your insurance adjuster but we do not work for them, we work for you and make sure you get what is due to you. We work on all mobile homes and been doing repairs on mobile homes for many years also. We work directly with the Department of Labor & Industries and do all the foot work they require to make the job go as smooth as possible.

"I had a fire in my living room ceiling caused by the wood stove flue and when the Fire Department was done, I had a real mess, a hole in the roof, and a cracked wood stove glass door when the fire department sprayed the hot stove. Hawaiian construction was only contracted to do the living room damage but they went far beyond that, which I am so very thankful for. Before they could really begin, my deck needed to be rebuilt because it had collapsed. So the part needed was rebuilt by Ramon and he built it even better than the previous one. I was impressed by how well it was done. Next, they had to replace the whole floor because it was warped from all that water, then the whole wall behind the wood stove and the whole ceiling. I asked them to sheetrock the ceiling rather than the standard manufactured home ceiling, and they did, which looks much better. After all the repairs, they painted the whole living room, then they painted the next adjoining room and the dining room and into the master bedroom and then the master bathroom. They painted all of those rooms, and ceilings. After carpeting the living room, they also carpeted all of the other rooms they had painted as well! They even repaired a hole in the ceiling of the master bathroom, and in the floor. They really surprised me with a lot of the things they did. Even a new kitchen floor. They even replaced my garbage disposal, a complete surprise to me! The insurance company said they would not replace the wood stove because it was the cause of the fire. Then I was really surprised when I walked in the house and found a new wood stove waiting for me. I don't know how they did it but I was very grateful for that and very shocked they had done it. They did tell me they like to do extra work for veterans, a very humble understatement, and they went far beyond just extra work. In fact, they did so much that I may have left something out. Altogether, they repaired, carpeted, painted, and replaced things in three fourths of the entire house, 3 bedroom, 2 bath, when the job was to be for a single room! I can't imagine they even made much for the job. They did so much extra work they may have even taken a loss for all I know. And I'm even late leaving this review, for which I must deeply apologize to Hawaiin Construction. I would highly recommend this company for anyone needing repairs to their home. The work is great and they take care of their clients."

FAQs for radon gas testing projects in Stanwood, WA

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
