"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"Home Genius Exteriors did a great job on my gutters. It was extremely fast and easy to be honest. I was really surprised at how quick the process was. The project manager met with me and we did a walk-through. I was truly satisfied with the work that was completed."

"Rightway Waterproofing is the company you want to come and waterproof your basement. I had initially set up a job looking for pros through Angie's List. I was contacted by Rightway Waterproofing via phone and email but did not respond as life happens. Well it rained really heavy again in August and I had more water in the basement. I reached out to them on a Friday and Albert contacted me immediately. They were able to come out on Monday to look at my property. Jake was thorough and friendly. He let me know what he thought we needed, explained everything thoroughly and gave us a quote which was completely reasonable. We accepted the bid and work was to commence on Thurs as they had an opening. Work was completed in one day. The area was kept pristine and they did an amazing job. The crew was courteous to my family. I could not recommend them more. I hope to have them out again at some point to finish my basement area as well. Try to keep in mind that during the season of covid many families are looking for ways to make more space in their homes or to have to home projects done. If you are waiting for work to be done just know that it is worth it! Thanks Rightway!!!"

"I can?t say enough good things about PeakPro Insulation! Before they came out, my attic wasn?t insulated at all and my house constantly fluctuated in temperature. When their team arrived, they introduced me to solar radiant barrier insulation. The difference was noticeable immediately. After the job was done, every room in my house finally felt consistent in temperature, and even my attic felt cooler while they were working up there. On top of that, they left the attic looking beautiful and clean. Highly recommend"

Insulation FAQs, answered by experts

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.
