"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."

"It went very well from the estimate process. Rory took the time to explain the process. As I had questions, he took the time to talk to me and explain in detail. Deb coordinated the scheduling extremely well. Among the estimates I got they were the most reasonably priced. I started out only doing the attic. They did such a good job, I decided to go ahead and have the crawlspace insulated as well by Madrona Insulation. BTW, shout out to a terrific installation crew!"

"We had a wonderful attic insulation experience with Madrona Home Services! They had the best pricing, including the Puget Sound Energy discount and they managed all the paperwork. We were able to schedule two weeks after the quote, and their team worked fast and efficiently on installation day. They removed old saw dust insulation and laid down batting, as well as going above and beyond by creating an 8x8 storage platform. Our house feels noticably cozier with consistent temperatures. 10/10"

"Acorns Attic was hired for a rodent removal job and I had some insulation replaced since it was dirtied with rodent droppings. Phil and team did a great job. They took plenty of pictures of before and after. I haven’t had rodents since they patched up the openings and the insulation looks great!"

Insulation questions, answered by experts

The R-value is a rating that measures an insulation's thermal resistance—in other words, how well it insulates. A higher R-value provides more protection for your pipes, and all pipe insulation materials should have an R-value listed on the product description or label. Each insulation type has its own R-value, which typically falls between one and five for most pipe insulation. When making a selection, Energy.gov recommends choosing a pipe wrap that is at least one inch thick, and the International Code Council (ICC) suggests choosing a material with an R-value of at least 3.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

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.
