"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."

"They installed new insulation for us in an un-insulated attic space. They were well-priced, on-time, and very easy to work with. Workers all wore protective equipment and were both professional and friendly."

"I’m very satisfied with the insulation work performed under my house. My home is now toasty warm on my feet. Phillip and his worker showed up on time, went about their work and cleaned up the mess created in the process. I am greatful that I found such a competent company."

"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

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”
