"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!"

Pacwest Floors of Bothell is more than just a flooring store. We are a smaller company with the same pricing as a larger store or chain. What that means is that you get the unbelievable pricing like a chain store, but receive the attention to detail and customer service that the larger stores sometimes struggle with. Our appointment only showroom offers a large selection of every type of floor-covering and counters. Pacwest also has the expert installation crews that they have been working with for over 20 years and the owner of the company has been in the industry for 35 years! We guarantee you will be thrilled with both the pricing and customer service!

"We purchased a home and our first undertaking was to install tile in the formal dining room and carpet in the library. The owner, Eric, spent a lot of time with us understanding the "look" we wanted and helped us choose the products accordingly. He has a great selection from which to choose, btw. We scheduled the installation about a month in advance. Eric's tile guy was AMAZING. I've never seen a contractor work so fast, meticulously and competently. He tore out the old flooring and laid the tile on day one. Left no mess and hauled away all the old flooring. He came back the next day and grouted the tile. It looks fantastic. It is one of the most "wow-factor" rooms in our home. The next day, the carpet guy arrived and we had our new carpet installed in a couple of hours. Again - a hard-working, fast and very competent worker. Overall, we have been extremely happy with this whole process. Not only was Eric great in helping us decide what to get - but his crews were efficient, fast and do great work. I've hired a lot of contractors in my years, but this has to have been one of the better experiences. I'd use them again. HIGHLY recommended! A+"

Insulation installs or upgrades FAQs

R-value measures how well insulation resists heat flow, which directly affects your home's energy efficiency. The higher the R-value, the better the insulation. By calculating the R-value needed for your specific climate and home design, you can choose the right insulation materials and thickness to keep your home comfortable and reduce heating and cooling costs.

You don't need to remove your old insulation before adding new insulation, as long as it's in good condition. Adding new insulation over existing materials can improve your home's energy efficiency. For example, you can install blown-in insulation around fiberglass batts or place rigid insulation over existing layers to enhance the overall R-value. However, if your current insulation is wet, moldy, or damaged, you should remove it to avoid health risks and maintain optimal performance.

Installing insulation typically takes five to twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the type of material and your home's layout. If you need to remove old insulation, have a larger home, or hard-to-reach areas, the project may take longer.

The International Association of Certified Home Inspectors has said foam board insulation can last up to 100 years if properly installed. Some insulation materials can suffer from water damage or start to sag over many years, thus reducing their insulating ability. Foam boards shouldn't suffer from sagging but have the potential to get damaged. Any broken pieces of foam board can reduce its insulating effectiveness.
