"when we noticed that the insulation in our attic was wet, we called Home Comfort. They came, look at the insulation, confirming it was wet and we had mold in our attic. They removed the wet insulation, put in new insulation after the mold was abated. The also added more vent tiles in the attic and sprayed insulation around the sole plates in our basement."

"Everything was fine until I got the final bill. The estimate they gave was different and the final bill was different. They had put extra charges. When I called them about it, they didn't back down. They also said that because of the extra insulation they used they did they couldn't reduce the cost. Other than that, the job was done fine. At one point, the insulation had blown in, they had a little problem, but that was worked out."

"Neil did the job fantastically and explained what he was doing throughout, always asked for an inspection to make sure it was done to my satisfaction. Pricing was extremely fair and he was timely and quick. Would highly recommend for any insulation work you need done. Can’t speak on the other work he does, but if it’s on par with what he did for me, then you’d be doing well."

"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?.?"

"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 FAQs, answered by experts

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

Yes, insulated vinyl siding increases the R-value of your home. Depending on the quality and brand of the insulated vinyl, you can get an R-value that is up to 5 times greater than traditional vinyl siding. This can be fantastic for homeowners who are trying to lower their utility costs.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.
