"Insulation Northwest did a fantastic job insulating my 1944 house recently, with Drill & Fill in ground-floor walls never before insulated, plus a complete insulation of the second floor attics and interior walls. They were super-careful cutting and drilling my old cedar shakes, replacing them perfectly and caulking them afterwards. They worked around plants without damaging a thing while doing the walls outside. I have old lath and plaster walls but blowing in the fill left not even a hairline crack or any trace on the inside. Much appreciated! They spent two long days at my house and they were clean, friendly, professional, and helpful . This is my second time hiring Insulation Northwest and I give them my highest recommendation."

"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!"

"Erick with AG construction came to my rental a week ago. He had the proper equipment to crawl under the house and determine what I needed to fix broken heat pipe, replace vapor barrier and replace insulation from a plumbing leak. I also had signs of rodents. He gave me a bid that was reasonable and was able to have his team on the job within a week. I stopped by as the work was being done and saw old insulation in bags headed for the dump. The area was left clean and his photos of the job look great. This is a very professional company and I would use them again for any crawl space work."

"I hired Acorn Attics to insulate my house and I couldn’t be more happy with their work. Phil and his crew were on time, friendly and incredibly hard workers. He worked with me on scheduling and made sure to keep our project moving even when we had a setback with another repair. I highly recommend them. They will get the job done. Thank you Acorn Attics and Crawl Spaces!!"

Insulation questions, answered by experts

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

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.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.
