"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."

"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."

"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"

FAQs for insulation service projects in Dover Afb, DE

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
