"United Insulation did a nice job insulating our walls and attic. The work crew was knowledgeable, personable and very neat. When they were done inside the house, you couldn’t tell they were here. It was very important to them to do a good job. The home is quieter, as we live near the Ohio Turnpike. The A/C runs less frequently and the home is comfortable, even during a recent stretch of 90 degrees days. We’re looking forward to the difference during the heating season and will probably update this review in November/December. Overall, we’re thankful we chose Donny and his crew at United Insulation. You should, too."

"I liked these guys from start to finish. Very friendly, did a great job, and cleaned up after themselves. Didn’t try to add a bunch of extra projects and expenses like other insulation contractors I spoke with. Came in with the cheapest quote too. Insulated my attic and one room."

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"Our experience was with Berry Insulation was wonderful. From the initial insulation evaluation with Paul through the completion of the project with Steve and his team, I was met with professionalism, competency, attention to detail, and respect. Paul, the sales evaluator, alerted me to rebate opportunities from Dominion and made multiple trips to the house, answered email quickly, and made numerous invoice revisions. Regarding the work itself - I was so very impressed with Steve and his project team. He truly was incredibly conscientious in doing a great job. He answered questions and kept me apprised of all steps of the process. Steve was kind and completely professional. The team with Steve -- each and every one of them -- was so very wonderful. Alex did an impeccable installation of the gable vents and the register vent and in all of the rest of his work. Anthony and Andrew were equally as capable and equally as expert in all of their work. I was truly blown away by every person on-site. Truly this was a great team and the house is already noticeably more comfortable! Thank you for all of the service from start to finish."

"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

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

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.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.
