"We’re building a new 1000 SF home and these guys did a great job. Easy to communicate with, showed up when they said they would and knocked the entire job out in a day. City insulation inspection passed without any issues the next day. SPF was even kind enough to upgrade to higher R-value insulation in some of our 2x8 walls at no added cost. Highly recommend!"

"We had Lake Atitlan Insulation remove our old insulation and replace it with R-38. I enjoyed working with Nanni from the initial meeting to the final step of installing the insulation. Very knowledgeable lady and truly exceptional customer service. A highly recommended insulation contractor."

"The workers were on time. Very efficient. They did a blower door test and found the air leaks and insulated these areas. Blew installation above the garage, cleaned out the crawl space and put new installation there and basement. Found a water leak from my toilet,Thank goodness. Covered everything in the basement and swept and cleaned up after. I would recommend them!"

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.

Insulation FAQs, answered by experts

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

You can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency. 

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.
