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."

Structural Engineering questions, answered by experts

Generally, you can tell if a home is bolted to the foundation by checking the foundation for plates. If you see that your foundational plates connect to wood or bolts protruding from them, this means that you have a bolted foundation. However, it's always wise to bring a home inspector in to confirm if your foundation is secure.

Costs depend on material choices, labor, and the extent of structural modifications.

Structural engineers typically conduct inspections during a home sale or renovation, looking for signs of structural damage in various structures throughout the building, such as load-bearing walls, joists, beams, roofing trusses, foundations, and chimneys. Some of the warning signs that structural engineers check for include:

  • Dry rot

  • Infestation

  • Shifting or cracking foundations

  • Erosion

  • Water damage

  • Sagging, shifting, or damaged walls, ceilings, or roofing support

By careful planning and reinforcement to maintain structural integrity.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.
