"The crew that originally came out were very efficient and friendly. They finished almost everything in the time that was stated. The only thing with them that I was concerned with was that they keep asking me what they were supposed to be doing. They knew that they were supposed to doing insulation but didn't have the details. And when i told them that I would have to go back to my paperwork they said that they would call the project manager. On the 3rd day they needed to do one last thing to an outer wall but couldn't do it because it was too cold and they were concerned that if they tried to remove the siding it would crack. They left on a Wednesday telling me that someone would contact me to come back on Saturday to finish the job. Fast forward to Friday, I get a few missed calls and then text messages saying that they had a crew in the area that wanted to come by in 30 mins. I wasn't home but finished up what I was doing to meet them at my house. When they get there they don't even know what the job is that they are supposed to be doing and don't have a ladder tall enough to reach the area. So they decided that they could do the job from the inside and said that they would need to drill a couple holes in my closets to fill the wall with insulation. They were very admit that that the holes would be repaired and the drywall fixed and painted and that someone in the company would call me and a crew would come out to do the drywall repair. So they do their part and leave. After they leave I realize that they put 6 holes in my wall. Not what i was expected but they did a decent job on plugging the hole back up with the piece of drywall that they removed. I waited for someone to call me about fixing the drywall but they didn't call. So after a week of waiting I called the company to ask about it and the mold remediation issue I was having (more on that in a sec). They seemed unaware on the drywall needing to be fixed and said they would send someone out to look at both things. A few days later someone comes out. They were unaware of the drywall repair but were there to look at the mold issue. Now about the mold issue. I will get back to the drywall in a min. So I paid for them to spray something on a strip of mold that we had in our basement and was told that after it has been sprayed that it would like nothing was ever there. Well after them spraying it twice it still looked awful. The wood looked but as black as before they came. So when these guys came to look at it they said that there was definitely no mold there. the problem was with my wood. So much for it looking like nothing was there. Now i have to hire someone else to sandblast it or something. So after these guys looked at the basement they said that they would look at the drywall. They look at it and are like "oh, i don't think we have the materials on our truck to fix this but I will take a look". They did have the materials and would tape it and mud it but weren't really experienced in drywall repairs but they knew enough to do the job. I should have stopped them right there but I thought it would be okay. Well once the mud dried I could tell what an awful job they had done. I will have to either try to fix it myself or hire someone to do it. And I probably should have called them back again but I am really tired of them sending me people that don't know what the job is before they get to my house and are not prepared. Only getting a C because the first crew was decent."

"My house is a little wacky and the proposal was to include all of the crawl space and ceiling surface area. Sadly there was no way to know that a portion of both were inaccessible to insulate. Was hoping to fix issues with freezing pipes by insulating but that is the part they could not access. The scheduling and some staff on the phone is a little dry on the phone. The crew who came to do the job worked their butt off and were super nice. CJ, who drew our proposal, was very nice and knowledgeable. He warned me that his estimation might be a little off but the estimation of the Pepco energy saving percentage back ended up being way off after the energy audit. That made the job much more costly than predicted and I had not planned for that. He was willing to adjust the bill slightly but not significantly enough to really make a difference. Overall, it is going to make a huge difference in the comfort in the house and the crew was very professional."

Insulation FAQs, answered by experts

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.

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

Generally, the cost of ice dam removal is not covered by homeowners insurance because it is often considered preventable maintenance. However, the damage caused by ice dams is frequently covered. Depending on your policy, this can include interior water damage, roof collapses, and damage to shingles. Coverage for personal belongings affected by leaks may vary. It is important to check your policy details or contact your insurer to confirm what your plan covers. Keep in mind that any damage resulting from a DIY attempt to remove an ice dam will likely not be covered.

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.
