"I contracted with TVP for engineering plans for a home addition in February, 2023. The sales person Phil McDodson, made an agreement to stay with the project through to the permit but walked away as soon as the county required additional information. At that point Janae Spinney stepped in and would not quit on me until that promise was complete. A special thanks to Joseph and Caleb for getting us through to the end. Every engineer and staff member with TVP was polite, knowledgeable and saw the job through. It was just approved January, 2025. Great company and I appreciate all you did for us!"

Summit Pest Management is a professional pest exterminator serving Portland and surrounding areas. Summit specializes in pest control, wildlife management, rodent control and commercial pest control.

"Bill was very willing to discuss the issue with me when I contacted him. He was also very knowledgeable about powderpost beetles, which was not true for several other pest management companies I contacted. I arranged to have Bill inspect the window frame and cavity after the window contractor removed it. He was very professional and identified the window frame as the location from which the beetles originated. Bill made several recommendations to the window contractor and took some beetles I had captured back to his office for detailed examination. The same day, he called me back and identified them as Lyctid powderpost beetles. Bill stated his opinion that further treatment of the window cavity was unnecessary. Although the window contractor would have paid Bill's inspection fee ($195) and for any treatment, Bill didn't charge anything! I was both surprised and impressed, and would highly recommend Summit for both professionalism and integrity."

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."

Structural Engineering questions, answered by experts

Through proper drainage solutions and compacting the foundation soil.

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

If your home's foundation was damaged due to shifting soil, the same problem will reoccur unless you stabilize the structure by adding posts in the bedrock.

Any issue that affects the structural integrity or soundness of a home is considered a structural issue. In addition to foundation cracks, other signs of structural issues include roof leaks, bowing walls, sloping floors, gaps around windows and doors, and more.

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.
