"The work was clean and the owner as well as, all of the employees were professional and friendly. The only criticism would be the failure to clean up the job site. They did haul most of the rubbish away but the employees left chunks of drywall mud and screws on the floor of the garage, empty bottles in the yard, and leftover materials, fiberglass insulation, were thrown carelessly on top of my personal belongings. Despite the messiness, I would hire this company again. ?"

"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

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

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.

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.
