"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."

Insulation questions, answered by experts

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.

An insulated garage door is a great long-term investment if it’s within your budget. They save energy and give the door year-round usability. In other words, the door pays for itself after a few nasty winters. Most modern garage doors already have a fair amount of insulation, so look into those options if you don’t feel comfortable splurging.

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

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.

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.
