Our experience with EcoTech was great from start to finish. We hired EcoTech to weatherize our house. They insulated our attic and walls with an environmentally-friendly insulation. Then they sealed the air leaks in our basement and insulated the floor over our crawlspace. Throughout the project, their crew was on time, left our space clean, and their crew was very friendly. Before they started this work, they tested for the presence of radon, since weatherizing a house can cause radon levels to rise if it is already present in the home. Radon is the second-leading cause of lung cancer in the U.S. They discovered that we had a radon level of 20 pCi/L, five times higher than the EPA's allowable limit of 4 pCi/L. We were stunned! They were able to put in a radon mitigation system which included our dirt crawlspace and concrete foundation basement. The radon levels in our house are now below 1 pCi/L, well below the safe level. Our energy bills have also decreased significantly - this January's natural gas bill was half of what it was last January. I'm thrilled to have a more energy efficient house, and being radon-free is a big plus! EcoTech was very patient and understanding throughout our project. When we had to put our radon mitigation project on hold for a couple of weeks to take care of an unforseen challenge with our partial crawlspace, but the crew at EcoTech was very patient with us and worked around our other foundation contractor to make sure that both jobs were coordinated effectively. Marshall managed our energy efficiency project seamlessly in partnership with the Clean Energy Works Portland program and Energy Trust. And I can't say enough good things about Ted, who managed our weatherization and radon mitigation projects.
