At Edgeline Restoration LLC, we are your local experts in water, mold and fire damage restoration as well as indoor environmental testing. We serve all of Snohomish and King county. Call us today at (206) 355-8282 for more information!

"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 mold & toxic material test projects in Seattle, WA

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
