"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."

"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

Insulation can be easy to install, depending on the condition of your walls, but there are many safety considerations and potential challenges involved. For example, most types of insulation are made from materials that can cause irritation if inhaled or if they come into contact with your skin. Additionally, installing insulation incorrectly can actually make moisture issues in your home worse.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Water heater blanket prices range from $20 to $40 on average, though you typically won’t need to spend more than $30 for all the tools and materials required for installation—which include the blanket itself, heavy-duty scissors, and electrical tape. Blankets with higher R-values will also be slightly higher in price.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.
