The Pull-Out Shelf Company® is one of the largest custom pull-out shelf distributors in the U.S. They have been making shelves since 1993 as a family owned business. Corporate website: www.PullOutShelfnw.com We are proud to be your local dealer for the Portland/Vancouver area. We have lived in the northwest in the Portland/Camas area all our lives. The northwest has been very good to us. Our mission is to improve the quality of your life by simply creating accessibility. That is exactly what Pull-Out Shelves do.

"Project took parts of two days. A brief visit to take measurements and a longer visit to install pull-out shelving in kitchen cabinets and closet/pantry. In all, smooth operation."

If you demand an ethical, educated, experienced and reliable home inspection company, give us a call. You deserve the best home inspector in the industry and I am committed to providing my very best service and expertise.

"James (company owner & inspector) provides an excellent service ($430). He is knowledgeable (18 years experience), punctual, had a quick turnaround time (37 page report available next day), and provided a wealth of information to explain findings. He also provides a Radon test (not purchased) and a Sewer Scope test (using sonar imaging, $125) separately upon request. I was equally pleased when James provided a home inspection (2014) on another Vancouver home I own."

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."

"My crawl space was flooded due to a hot water leak, major moisture damage and unfortunately I did not know about Willamette restoration and used another company to dry out crawl space but walls in laundry room and entry had to be tore down and that's when Willamette Restoration came into picture and saved the day. They completed the finish work walls, flooring, countertop, painting, replacing cabinets and I cannot say enough about their professionalism, timely manner in getting the job done.

Radon Detection and Reduction questions, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

It is worthwhile to get radon testing done, especially if you haven’t in the past and don’t have active radon monitoring set up in your home. According to the American Lung Association, radon is a potential issue in all states, and testing is the best way to determine if it’s a current problem in your home. Radon testing includes professional tests that determine ongoing radon levels in your property, and it usually includes a mitigation protocol to help you decide what measures to take to protect your home and household members.

Yes, DIY kits are available, but professional testing provides more accurate results and comprehensive reports.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.
