"I had Proficient Blow in Insulation into the walls of our Mount Vernon 1920 house. The inside temperature was 10 degrees warmer without us doing a thing differently, that was in January last year. We also had them insulate a 1000 square foot addition. Quality and affordable work every time. Thanks guys!"

I own a 1937 farmhouse in Whatcom County. I had concerns about the insulation in the crawl space and the attic. The owner of RGS came to my home and spent an hour inspecting the areas I was concerned about after which he sat down with me, explained what was needed and gave me a bid to do the work. The owner is as professional, knowledgeable and courteous as any business owner I have ever met. He quoted me a great price and gave me the highest quality of service I could have hoped for. I was so happy with RGS that I asked him to inspect the crawl spaces of two rental properties I own in Bellingham. I highly recommend that you ask RGS for to bid on any of your insulation needs. You will not be disappointed.
