"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 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.

"I intended to insulate an one car garage and the attic of the whole house. They were prompt to provide an estimate and very professional and honest on suggesting best solution (ended up with not doing the attic for now). The job was completed fast and really happy with the result. The crew was friedly and respectfull. Kept the place clean after all the blow in insulation."

"It was excellent. They performed insulation quickly and efficiently. The cost was in-line with the quote. I was very satisfied with their work and I would use them again. Their price was fair. "
When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
