"The guys at NW Weatherization did an excellent job installing additional insulation in my attic and crawlspace. They also reattached the exhaust fan boot. I can tell that the added insulation is helping keep my home warmer since the furnace doesn't come on as often and run as long. Thank you Ryan and everyone at NW Weatherization!"

"The estimator implied the insulation job would have a finished appearance, knowing that no sheetrock would cover the ceiling insulation in the shop. The result is far from the implied final product. A VRR product covered the unfaced insulation as requested. Ragged torn and cut edges and millions of staples exposed, no taping. I would not recommend this company for this type of installation. It costed less, but there was a reason. We even offered to pay more to have them finish the job right, but they didn't want to do it."

"They installed new insulation for us in an um-insulated attic space. They were well-priced, on-time, and very easy to work with. Workers all wore protective equipment and were both professional and friendly."

Customers say: True professional

"They did a very thorough crawl space clean up and detailed and well secured installation of the vapor barrier . They were honest, and efficient with positive energy. The issues are with communications from the office. They could be more professional, timely and thorough."

"When I bought my house it was discovered that rats had nested in my crawl space. The rats were long gone but the smell wasn't. Dillon and his crew came out and gave me a reasonable quote. They set up a fan to get the smell out until they could start the work. They went above and beyond cleaning out the old stuff, repaired vents that were coming apart and arranged to get new insulation installed. Super friendly and easy to work with."
