"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!"

Family owned business with over 17 years of experience handling all of your Insulation needs for residential and commercial. roll insulation, blown insulation ,spray foam, etc.

"I needed my attic insulation updated. It had the original “blown in” loose material from 1975. After 49 years it had deteriorated and compressed. It was only a few inches deep. Also a leak in our old roof (recently replaced) had caused some mold in the old insulation. It had to be removed completely and redone. I called JB Insulation and asked for an estimate. Jose came over and inspected our attic. His experience and expertise was evident by how he explained everything. I felt very confident that I wanted his company to do the job. His price was very competitive and offered us the most value for our money. On the day of the job, his guys took much care in preparing for the job. They covered and taped our floors and wall corners to protect our home’s interior. They used a high powered insulation vacuum and removed all of the old insulation. They installed the new insulation and new baffles all in one day. Our attic looks great and we are really happy with their work. Yes I would recommend JB Insulation."

Insulation questions, answered by experts

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

On average, attic insulation costs $1 to $3 per square foot, so for a 1,800-square-foot attic, you’d pay $1,800 to $5,400, including materials and labor. The cost can vary depending on what type of insulation you use, how many insulation layers you need, and whether you need to remove existing insulation first.

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, including recycled denim and cellulose from natural fibers.

Natural fiber batts and spray foam insulation both work great for soundproofing. Newer materials, such as hemp batts, are more expensive but more effective for insulation and sound blocking. They are also more sustainable. There is also a professional system called Blow-In Blanket Insulation (BIBS) that is soundproof and moisture-resistant. However, BIBS must be installed professionally and can be a costly investment.
