"Lake Atitlan Insulation did an excellent job in my attic. They removed the old insulation, installed a solar attic vent, replaced the bathroom vent duct, and added new blown-in fiberglass insulation. They also installed radiant barrier on all the attic roof rafters. The work was completed professionally and thoroughly. I highly recommend them."

"It went very well from the estimate process. Rory took the time to explain the process. As I had questions, he took the time to talk to me and explain in detail. Deb coordinated the scheduling extremely well. Among the estimates I got they were the most reasonably priced. I started out only doing the attic. They did such a good job, I decided to go ahead and have the crawlspace insulated as well by Madrona Insulation. BTW, shout out to a terrific installation crew!"

"We had a wonderful attic insulation experience with Madrona Home Services! They had the best pricing, including the Puget Sound Energy discount and they managed all the paperwork. We were able to schedule two weeks after the quote, and their team worked fast and efficiently on installation day. They removed old saw dust insulation and laid down batting, as well as going above and beyond by creating an 8x8 storage platform. Our house feels noticably cozier with consistent temperatures. 10/10"

"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!"

"My 1959 home with unique siding presented specific challenges on this job. Some of the plug work done was PERFECT, and much of it was not, resulting in unsightly exterior appearance and challenging sanding and finishing being required by me, the homeowner. This company COULD have done all the plugs perfectly, but chose not to do so. In addition, I had to request a receipt for the work, and I was not provided with a written copy of the verbal warranty stated by the owner of the company."

Insulation questions, answered by experts

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

For a DIY solution to protect an outdoor faucet from freezing, you can craft a cover using spare rags, a durable plastic bag, and duct tape. However, be aware that this method may not be as effective as a store-bought cover. Fabric like rags or old towels can absorb water, which could freeze and cause problems. While a DIY cover can work as a temporary stopgap, a proper outdoor faucet cover is inexpensive (often $5 or less), easy to install, and readily available, making it the recommended long-term solution.

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.”

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.
