"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!"

FAQs for insulation install or upgrade projects in Seattle, WA
Yes, insulating an unfinished basement delivers meaningful benefits even if you don't plan to finish the space. Proper insulation reduces heat transfer through basement walls, which can account for up to 30% of a home's total energy loss.
This improvement enhances comfort throughout your home while potentially reducing energy costs. Insulation also helps manage moisture levels, protecting your home's structure and improving indoor air quality.
Rigid foam board and spray foam insulation provide superior moisture resistance for basement applications. These materials create effective vapor barriers while delivering high R-values per inch of thickness. Rigid foam boards resist water absorption and can withstand occasional dampness, while spray foam creates an airtight seal that blocks humidity infiltration.
For basements in humid climates or with moisture concerns, these options outperform fiberglass or wool alternatives.
Insulating basement walls provides the greatest benefit by reducing heat transfer through your foundation. This approach helps maintain consistent temperatures throughout your home and keeps floors above the basement warmer during cold weather.
Ceiling insulation might be appropriate if you specifically want to isolate the basement from living spaces above. In most cases, addressing the rim joists and exterior walls delivers the best performance for energy efficiency and moisture management.
Many building codes require vapor barriers when insulating below-grade spaces like basements. These barriers help control moisture migration through foundation walls and floors. Certain insulation types, including rigid foam and spray foam, provide inherent vapor barrier properties. When using fiberglass or wool insulation, a separate vapor barrier becomes necessary. Always check local building codes for specific requirements in your area.
Signs that basement insulation needs replacement include persistent cold spots, unexplained increases in energy bills, visible moisture damage, musty odors, or mold growth. Physical deterioration, such as compression, sagging, or discoloration, also indicates potential problems.
In older homes with outdated insulation materials, upgrading to modern options with higher R-values can significantly improve performance. When in doubt, professional inspection can help determine whether repair or replacement represents the best approach.
