"Lake Atitlan Insulation did an excellent job in my attic. They removed the old insulation, installed a solar attic vent, replaced the bathroom vent duct, and added new blown-in fiberglass insulation. They also installed radiant barrier on all the attic roof rafters. The work was completed professionally and thoroughly. I highly recommend them."

"This company is fantastic! 1. Out of the 5 companies I was considering for insulation replacement (yes 5), their quote was the only one that was itemized and understandable. You knew each task you were paying for as well as what the workers were promising to deliver, which is extremely important when dealing with contractors. I found this out having met with 20+ over the last month. 2. They had the most reasonable price, and Rory in particular worked to volunteer his expertise on what our situation needed/did not need with an honesty that is hard to come by because it did not come off as self-serving or trying to take advantage of our lack of expertise. 3. They were reliable, on time, and very communicative every step of the way. They touched base frequently about our complicated situation, they were available for price discussions, and they were direct in communicating arrival and finishing times. I was extremely impressed. 4. The individuals at this company went above and beyond the call of duty. Rory was a pleasure to deal with; he reminds me of the neighbor you want to have because he has great advice, good contacts if you need work outside his company, and reasonable suggestions for what you can do to fix things, and to boot he was extremely available. He even answered our many calls with random questions off-work hours AND he volunteered to come out himself again outside of work hours just to help figure out the steps to fixing our problem. Debbie was affable and an organized presence on the phone. The other staff we worked with- Santiago, Rafael, Luis, and Felix- were all extremely courteous and hardworking during the projects. 5. They worked to coordinate with other contractors without me having to micromanage anyone. I had a roofing company, arborist/tree service, and vent cleaners on site. They were able to navigate their own working space and work in tandem on the roof with the roofers to replace the insulation on the cathedral portion of the house when the underdeck was ripped off, as well as add baffles appropriately. 6. They brainstormed to fix problems we were having at extremely reasonable prices. Example: The attic portion of my home was missing half the ceiling (had to be removed because of extensive mold damage) and they helped me place drywall so we could replace the insulation on the timeline we initially agreed to. It saved my husband and me a lot of money and heartache. What more could you want from a company? The biggest impression I walked away with is that this company actually cares about your situation. My husband and I were purchasing a new home in need of a lot of repairs. We have a toddler and I am third-trimester pregnant. With the move, the unpleasant relationship we had with the previous owners of our home, the strain on our finances, and the overwhelming stress of finding new problems everywhere we looked, I can only say I am extremely grateful we went with Madrona Home Services. Thank you!"

Customers say: Quick response

"We contacted them to do blow-in and crawl space insulation, but they were very thoughtful and thorough in looking at all the factors with our house and recommending against blowing in the walls and ceilings. In the end we only did the crawl space. I was impressed with their honesty and high ethical standards. They could have easily taken our money and blown in the walls and ceilings, but they seem to truly care about getting good results and giving customers top value. The work they did on the crawl space was excellent. It feels strange to call insulating a crawl space beautiful, but they truly did a beautiful job and we are thrilled to have cold air no longer seeping into our house from below."

"My 1959 home with unique siding presented specific challenges on this job. Some of the plug work done was PERFECT, and much of it was not, resulting in unsightly exterior appearance and challenging sanding and finishing being required by me, the homeowner. This company COULD have done all the plugs perfectly, but chose not to do so. In addition, I had to request a receipt for the work, and I was not provided with a written copy of the verbal warranty stated by the owner of the company."

Insulation questions, answered by experts

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

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.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

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.
