"We were considering upgrading our insulation but weren't sure if it was worth the investment. After consulting with Lake Atitlan Insulation, they convinced me it was the right choice. The insulation they installed not only made our home more comfortable but has already saved us money on energy costs."

"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!"

"Salvador arrived when he said he would, stayed for a few hours. He showed us what he was doing and took the time to explain the results and what our options are to improve the insulation in our house. We received a quote in the mail a few days later, which covered everything we had talked about, broken down in pieces (attic, basement, exterior walls) in case we can't do it all at once. I also spoke to Rob one phone and he was very willing to work with us on what we will do ourselves. Great experience overall. We have already hired them to insulate the attic."

Insulation questions, answered by experts

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

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.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.
