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."

"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

In Longview, prioritize immediate action for foundation cracks, roof sagging, or signs of water intrusion, as these can worsen quickly and impact safety. Less urgent projects, such as non-structural renovations or deck upgrades, can often be scheduled for dry seasons. Always factor in local weather patterns, permit processing times, and contractor schedules when planning your project timeline.

Helpful?

In Longview, be wary of quotes that lack clear details about scope, omit references to local building codes, or fail to address site-specific risks like soil movement or flood zones. If a professional avoids discussing permit timelines, doesn’t provide recent local references, or skips a site visit, these are warning signs. A reputable expert will explain deliverables, address local hazards, and outline inspection requirements.

Helpful?

New homeowners in Longview should start with a thorough evaluation of the home’s foundation and framing, especially if the property is older or near the Columbia River. Assess for moisture issues, check attic and crawl spaces for structural integrity, and review previous modifications for code compliance. Addressing these areas early helps prevent hidden damage and ensures your home meets local safety standards.

Helpful?

Homes in Longview with visible wall or foundation cracks, uneven floors, or recurring moisture problems often benefit from structural upgrades. Properties built before modern codes, especially those in flood-prone areas or with older framing, are strong candidates. If you notice persistent sticking doors, shifting walls, or have plans for major renovations, a structural assessment can help protect your investment and improve safety.

Helpful?

When planning in Longview, consider the area’s high rainfall, potential for flooding, and soil stability, which can affect foundation and drainage design. Some neighborhoods may have historic preservation guidelines that influence project scope. Seasonal storms and power disruptions can also impact construction schedules, so plan ahead to minimize delays and ensure your project aligns with local environmental and regulatory requirements.
