"The staff was friendly and professional. They demonstrated a desire to get to work asap which made the selection easy. Also got a spray foam insulation bid for crawl space and we will go with SPF for this large expense. Spay foam crawl supports our heated floors so that more heat will heat people opposed to rats in the crawl..."

"Insulation Co (Jo Estrada) had insulation installers come to our century old house to remove old attic insulation, do a bit of mold remediation, insulate the bathroom fan exhaust, cover the two previously open gable spaces at either end of our roof, then blow in new cellulose insulation. All this took a day, and all was cleaned up like nothing happened. Polite, efficient, professional, and the price was competitive."

"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!"

"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

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Yes, spray foam insulation can be applied to your ductwork and effectively insulate your ducts. Blanket insulation is the easiest insulation product to DIY since it is easy to wrap around ducts. However, spray foam insulation can also benefit your HVAC system if applied to air ducts.

DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.
