"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 attic insulation installation projects in Seattle, WA

The best type of insulation for your attic depends on your climate, budget, and whether your attic is new construction or an existing space. For example, structural insulated panels are ideal for new builds and offer excellent energy efficiency. In warmer climates, reflective insulation can reduce cooling costs, while blown-in, loose-fill, and spray foam insulation are great options for filling irregular spaces in existing attics. It's important to consult with a local attic insulation prol to determine which insulation type best suits your specific needs.

Absolutely. Insulating your attic reduces heat loss in winter and heat gain in summer, leading to lower energy bills and a more comfortable home year-round. It can also increase your home's resale value, as energy efficiency is a desirable feature for buyers. Investing in attic insulation is a smart way to improve your home's efficiency and comfort.

Yes, you can usually add more insulation to your attic over the existing material to improve its effectiveness. If your current insulation is dry and in good condition, adding layers can enhance thermal resistance. However, if the existing insulation is wet, moldy, or damaged, it should be removed and replaced to prevent health issues and ensure proper insulation performance. It's important to have a professional assess your attic insulation to determine the best course of action.

Insulating an attic can take anywhere from five hours to two days. The project length depends on the insulation material you choose, for example, spray foam insulation takes about one to two days to install. Another factor is if you need to remove old insulation before adding in new insulation.

Yes, you can over-insulate an attic, although this isn’t as common as under-insulating your home. Too much insulation can lead to inadequate ventilation, blocked vents, and poor air circulation, resulting in mold or trapping in heat. To avoid these issues, contact your local insulation professional about finding the right R-value for your home.

You typically do not need to hire an electrician for standard attic insulation projects if you're simply adding or replacing insulation. However, if your insulation work involves moving electrical wiring, installing new fixtures, or addressing any electrical issues, you will need to hire a licensed electrician. It's important to ensure that all wiring is properly handled to prevent safety hazards and comply with building codes. If you suspect any problems with your attic's electrical system, consult a local electrician before proceeding with insulation.
