"Highly professional and extremely accommodating. There were bats in my attic when they went in to redo the insulation. They calmly (as they could) told me the situation and came back at a later time with no added cost. Did an excellent job, and had a incredible attitude throughout. Cannot recommend enough. Thank you!"

"They provided blown in insulation for my home. They were able to schedule an appointment quickly and showed up on time. Their price was approximately market price (not a bargain). They did a satisfactory job, but their cleanup left a lot to be desired and they had to quickly repair something that was accidently damaged during the blow-in process. The employees were nice and professional, but didn't seem to be experts in the field. Their office was helpful in answering questions and handling payment processing and energy tax rebate questions."

Insulation FAQs, 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.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.
