"Price was about average, can't complain - don't remember exactly how much or exact service date (disclaimer).  Company screwed up the scheduling.  Installer was busy with personal life and we had to work around their schedule.  Inconvenient.  Came out and sprayed insulation in the garage.  They left the door open to the basement so the entire chemical smell inundated the basement.  The spray was general even but there seemed to be small holes and spaces generally through out the insulation.  When I inquired about the small spaces the response was they generally use the small spray cans you can get at Home Depot\Lowes but that they didn't have any.  I said I would take care of it myself, I had enough inconvenience with the screw up in scheduling.  Other than that went well - it's not that involved, just spray foam. 
They did clean up the mess relatively well, but not perfect."

"The team worked at my house for 2 days.  Day one, the blew insulation in the 10" of insulation in my attic and began installing R19 insulation in the floorboards. Day two, they completed the R19 insulation and ran the aeroseal through the ducts.  The guys did a great job.  Cleaned up after themselves, which my wife really appreciated, and my power bill has gone down drastically.  Just to provide some prospective, my January power bill was $525 in a 1900 SF house!!!  Since Energy Sharks came, my power bill has been less than $130 each month."

"They installed solar panels as per contract. They were on time and removed all material when done. I had roof damage from a storm and they repaired it at no extra cost. So far I am happy with this company and plan on using them again for house repair.

Insulating your attic can help keep your home warm in the winter and cool in the summer. It can also reduce your energy bills. There are different types of insulation to choose from, including fiberglass, cellulose, and foam. Each type has its own benefits and drawbacks. Fiberglass is the most common type of insulation. It's affordable and easy to install, but it can irritate your skin and lungs if you're not careful. Cellulose is made from recycled paper and is a more eco-friendly option. Howe

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

FAQs for insulation service projects in Barnwell, 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.
