"I called Carolina Energy Conservation to have some new insulation put in my attic. The estimater came out within a few days of the phone call, and I received a detailed e-mail about what to expect. Matt gave me a good run down of what I needed to make my upstairs floor more comfortable. He called ahead of time, was on time, and was very professional. The estimate was for 4,000 board ft of insulation, 800 sq ft of radiant barrier installed, and an attic tent/hatch. Total cost was about $1600. They asked for a down payment of 30% up front, which I paid. Matt told me I would recieve a call to schedule the work within 1-2 business days. That never happened. After 1 week I called and spoke with Mary, who informed me their office manager who does schedules was out sick the previous week. She assured me he would call me back to setup a time for the work to be done. That never happened either. Fast forward another week. I called a 2nd time, and finally got an apointment setup for the following week. The two guys they sent to do the job were friendly and professional. After a few hours they let me inspect the work, and it was completed to my satisfaction. I normally have to set my AC to 73-74 in the summer to keep my upstairs comfortable, and the HVAC turns on quite often. Now I can set it to 76-77 and it remains comfortable, and the HVAC doesn't run as often. All in all I am happy with the overall experience, guess they just got hung up on scheduling."

"They didn't end up doing the work. They were really high on what they wanted to do. Other people who looked at the porch said that it was not causing an issue with any water intrusion and that there doesn't seem to be any signs on the posts that this could have been recent, it could have been long ago. So no work was done. It was a front porch that had just the level concrete on one side was dipping just a little bit. I think they were going to pump it up from underneath or something like that to level it out. I would say that their response time and their professionalism of getting the quote to us on a timely manner was good. The quote was high and yet the work was not necessary according to other quotes. They should be honest to say when repairs are necessary and when they are not. The guy who showed up was nice and professional and was on time. There was a decent response time."

FAQs for insulation service projects in Florence, SC

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.
