"On day 1 they removed (sucked out) 3 levels (and three different types) of insulation. They were very neat and cleaned up afterward. They showed me pictures of the cleared attic. On day 2 they blew in new insulation, sealed an unused vent (which was causing a draft) and installed a new attic hatch (old one was broken, unsealed and not insulated causing a draft). Everything was done as agreed and in the timeline expected. They are also a partner with Energy Trust of Oregon which is a bonus."

"Acorns Attic was hired for a rodent removal job and I had some insulation replaced since it was dirtied with rodent droppings. Phil and team did a great job. They took plenty of pictures of before and after. I haven’t had rodents since they patched up the openings and the insulation looks great!"

"I got a rebate from the state for having this service done. Their were two men that came out and they were able to get it done within two days. They put insulation in under our home and in the attic. I did notice a difference in our home after this. They were very professional and you could not even tell they were there."

Insulation questions, answered by experts

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

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.

Winterizing your outdoor plumbing keeps your outdoor spigot from freezing and potentially bursting. This includes draining residual water out of the pipe and spigot after turning the valve off, then removing garden hoses and other attachments from the spigot before winter comes. Insulating the pipe that leads to the spigot and installing a freeze-proof faucet also help, as does installing an outdoor faucet protector.
