"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"Every time it rained we would get water in our garage and basement. Thought about getting water proof system installed for years and finally got it done with Rightway. We have had 2 serious rains since the system was installed and have not had a drop in our basement.
If you have the same issues as us i highly recommend you finally get it done and use Rightway and you will not regret it.

"When Mike did the free estimate, he told me it wasn't the walls where we were losing heat. It was my crawl space. Also, totally above the work of insulating the space, he noticed an air duct was disconnected. He got the straps needed to fix the vent and didn't charge me. Excellent customer service. He was neat, on time, and quick with the insulation."

"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"

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.
It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.
Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
