Environmental Works LLC
Environmental Works LLC
We're innovative, hard working and we get the job done right from the science to the site. From our administration team, to the project managers and field crews, our employees are highly skilled and thoroughly trained professionals. We specialize in air quality testing and mitigation (Radon), underground tank decommissioning, sewer inspection & repair, plumbing services, directional drilling, environmental site assessments and environmental restoration.
"I hired Environmental Works on the recommendation of a co-worker. Not only was it the least expensive of the three bids I received but it was also the only company that offered a lifetime guarantee on its work. The entire installation of a radon mitigation system in my home took less than six hours. The company guarantees that its radon mitigation system can keep radon levels below 2.7 pCi/L. A three-month radon monitoring test, completed ten months after the installation of my mitigation system, indicated radon levels at 1.4 pCi/L. I am very pleased with the work that was performed at my home."

"I was very happy to find Avos-Inc. could complete the whole project using their ingenuity. Another fence company could have done the fence section but said they could not do the brick post portion. Avos removed the fence sections attached to the brick pillar. They built a new 8' fence section and reinstalled the two fence sections. They used 3 men-power and crane or jack equipment to lift the column up to remoter the grout at bottle and top of split. I appreciated that Avos was able to remove the brick pillar without it breaking, as that saved me money since I didn't have to have a new brick pillar built. The new fence section has a durable powder coat finish and looks very professional. Thanks for getting yet another home maintenance project off my list. Kudos to my neighbor who cut down the tree on his property that was creating the problem. Also, Avos coordinated very well with my neighbor on the timing of the fence work and the tree removal done by the Tolleson Family Tree Care of Washougal, WA."
