"Jeremy was quick to come to my house to get me a quote and came on a weekend. He was very thorough and gave advice on how to get my insulation needs done. When I scheduled him to come and do the work on my crawl space and partial basement he came on time and done a amazing job and was quick and thorough. I will recommend him to all my family and friends. Will use his services again for sure. I am also going to get him to come fill my walls of my house."

"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."

"Excellent, family-run business. I called on Monday afternoon about adding insulation and the job was *completed* within 48 hours. The estimator (company co-owner) recommended reasonable solutions and did not try to "sell" me on things I didn't need. The installers were very courteous, showed up early, cleaned up well, and even put my stuff they had to move right back where they found it. I wish I called them years ago. Very pleased with this job and company."

Insulation FAQs, answered by experts

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

Yes, energy-efficient homes are increasingly desirable in the market.

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.
