"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"He showed up ready to go, very knowledgeable knowing how to and why it would be a good choice for our project. our basement needed extra insulation so our pipes don’t freeze, i’m super happy with the job, and the clean up was done right away. couldn’t tell he was even there working. i really appreciate when you don’t have to clean up after a contractor it shows a lot of respect."

Insulation FAQs, answered by experts

No, you shouldn’t wrap a towel, old T-shirt, or other porous fabric around your faucets. These materials absorb water, which can make your faucet more likely to freeze. Instead, you want to use waterproof, insulative covers that can seal tightly around the spigots for the best protection against frozen outdoor faucets and pipes.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

An insulated garage benefits from roof vents to ensure proper ventilation and prevent moisture buildup. Insulation can trap moisture in the garage, especially during temperature fluctuations, and roof vents play a crucial role in expelling the moisture in the air. Including roof vents promotes air circulation, preventing condensation and enhancing overall air quality.

Not necessarily. A higher R-value simply means that the insulation has a higher heat resistance and performs better in terms of how much heat passes through the material. This can be better for some homes, or it can be too high of an R-value for other homes. Again, your climate zone determines whether the insulation is better for your home.

No, 55 degrees Fahrenheit is not too cold for a house, as it’s a temperature that will keep your pipes and appliances from freezing. Well-insulated homes can even go to 50 degrees, but check with an HVAC pro before opting for such a low temperature. Stick to 55 degrees to be on the safe side.
