"We had siding, windows, and insulation installed at a fair price. Brandon and his crew were very professional, personable, and did excellent work. They responded quickly to all of our requests. We would highly recommend Home Comfort Keepers. Don & Eileen Emerson"

"The custom lentils around the foundation came out beautifully. You would never know they
are not the original, and the new one was poured thicker than the old one, so should last
a long time! The sidewalks came out perfectly and the crawlspace area is very nice. Throughout
the whole process, I dealt with Brian Flanagan who kept me informed of the work and personally
inspected and pointed out minor imperfections I didn't even notice and fixed them. I am very
happy with the customer service, the price and the work performed. I would definitely hire them
for any additional work -- I'm already in contact with Brian about attic insulation."

"We had them come out to give me a price on adding more insulation to 2 sides of our house. And to put new guttering on the 2nd floor . While here they talked us into insulating the attic too. We agreed the attic would be a good job for the guys to do in the winter. We signed papers and gave them a $2500.00 dollar check for the down payment . The salesman Josh said he be in touch with us the next week to see when they could do it. Josh had come out on sat October 7th. Well I tried to send photos of our house to Josh 2 times . So after a week & half I called the office. And ask did he work there?She said yes she would have him call . But no call . So I called office and she gave me there email and I sent pictures to her. I had.questions on the photos, and asked them to call . Ii called in again to see if anything was being done, and secretary said the boss said they were working on a schedule and someone would call me. At this point we are 3 weeks out from our signing and cant get a call from anyone. We are at this point not happy, and figure our $2500.00 is gone. So my daughter called to see if there was a process to get our money back. And I got my 1st. Phone call . 1 day from being 4 weeks of signing. And this guy as nice as he was said we probably won't get it back because we signed a contract. . I have delt with other companies , and any time I sign a contract ( that big ) some always calls to go over it , or to ask if you have questions. But now I don't want them, I'm just going to get someone else .if I can get my money back. If they can't return my calls, why should I think there going to do what I want them to do?.?"

Insulation FAQs, answered by experts

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.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

Yes, you should insulate your copper pipes to help regulate their temperature. Well-insulated copper pipes will be protected from freezing and can conserve energy by keeping hot water warm for longer. Foam rubber insulation tubes are the best pipe insulation to prevent freezing since they fit tightly around the pipes while still maintaining some flexibility.

Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.

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.
