"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."

"Edgar listened to my request to perform the tasks of insulating the HVAC ductwork and hotwater lines before installing the R30 batts in the joists. He did a good job in cleaning up the fallen insulation pieces from the floor, but there was still residual insulation dust on the floor and on my storage boxes. The tape he used to secure the ductwork insulation batts kept coming undone after he left, which I later re-taped myself. Overall, the quality of the work was great, but the cleanup could only be rated as 'Good'."

"If you want someone to do a project in an unfinished basement, I would recommend Right-Way. However, if you want someone to do this work in a room with special conditions, as we did, I would not recommend them. The sales person was very professional and up-front. The workers were very pleasant and cleaned up fabulously after their work. They did a good job with the actual installation. They also demonstrated how to use everything very well. Our complaint is that we carefully explained to everyone that they were working in a finished room with a carpet that was not a basement (that was obvious) and that the walls were going to be deeper after we had insulation installed in the room. However, they installed the sump pump was too close to the wall without enough room for regular 2x4 studs and sheetrock and there was a cleanout that was also too close and stuck up so that we could not replace the carpet. The workers were also told to carefully remove the molding and paneling because we wanted to reuse it. Either they were not very careful or there was some other problem, but there was little we could use. Although someone came back to remove the cleanout and recessed the access to the sump pump, the bottom line is that it isstill partially under the new wall and our contractor (who spoke to the workers before they started jack-hammering the floor) had to do extra work to put the room together. I feel that whoever planned the job didn't think through the fact that we weren't going to use the cleanout in the first place (who would bring a hose into a finished room?) and that you need at least 4" clearance for a 2x4 studded wall. We do now have a room that is a lot more protected from water and everything is back where it should be, but it was a lot more complicated than it needed to be."

"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

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.

Upgrading insulation offers several benefits, including improved energy efficiency, which leads to lower heating and cooling costs. It also enhances indoor comfort by regulating temperature and can provide noise reduction. Additionally, better insulation has a reduced environmental impact and can increase your home's value and overall livability.

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.

DIY insulation installation is feasible, particularly for basic rolls or batts, if you have the right protective gear and knowledge. However, hiring a professional ensures even, full coverage for maximum efficiency.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.
