"Sergio and his crew timely completed a complex insulation installation. Near Me Insulation LLC gets highest marks for flexibility in terms of traveling from Burlington to Glacier and completing the work with the highest skill level. The inside of my Ski Barn in Glacier has a height of 35 feet at the peak--several rooms with outside walls needed insulation. Sergio and crew also wrapped pipes and replaced window flashing with great care and expertise. Highly recommended contractor--reasonable price."

"I had insulation blown in between my floor joists supporting the main floor of the house. Installation was timely and meticulous. Mesh fabric was installed tight and secured with staples driven in with an air gun, evenly spaced 1 inch apart. Insulation blown in, filling the space between the joists and every crevice. The fabric gave my cellar a finished look, resembling a drywall ceiling. They left the job clean and better than when they started. They used top-of-the-line materials, tools and equipment. I highly recommend Proficient Insulation Solutions."

"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.
