"Insulation Northwest did a fantastic job insulating my 1944 house recently, with Drill & Fill in ground-floor walls never before insulated, plus a complete insulation of the second floor attics and interior walls. They were super-careful cutting and drilling my old cedar shakes, replacing them perfectly and caulking them afterwards. They worked around plants without damaging a thing while doing the walls outside. I have old lath and plaster walls but blowing in the fill left not even a hairline crack or any trace on the inside. Much appreciated! They spent two long days at my house and they were clean, friendly, professional, and helpful . This is my second time hiring Insulation Northwest and I give them my highest recommendation."

"Great service and a pleasure to work with. The whole process from the initial estimate through the installation of the additional insulation in our attic was easy and fast. Work was completed on time and on budget. They even completed the paperwork for rebates from our local power and gas companies, which knocked about half off the total cost. Would definitely recommend."

"The job was done timely. They went out of their way to make sure everything from replacing the insulation to a thorough rat abatement was done right and explained everything to me. They even installed some bird spikes for me."

Insulation questions, answered by experts

Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.
