"I like working with this company. Rob Blake, the owner, is very professional. I called him because a hot water heater problem had revealed that the foam from a 2011 job had not filled the cavity in the wall as thought during the 2011 job.  I did not know if this only applied to the water heater closet or to the entire cabin.
Rob's response to my call was "That's why you have a lifetime warranty!"  Wow.  Not used to that.  Rob came out the next day and crawled around under the cabin and poked wires into outlet cavities and showed me that the foam was only thin in the water heater closet, and given the construction of the closet, that made sense.  Rob wanted to schedule a return within a few days to fix the problem before the weather got cold.  I asked him to bid the top floor of my house to do at the same time.
The fix was free and the top floor of my house was 3200.  So altogether, I have spent $7100 with retrofoam, to insulate three houses; one about 750 square feet; one about 450 square feet and one about 4,000 square feet.  
As with the first job, the workers were polite, professional, hardworking and very thorough. They were very nice about things like taking down a bird feeder for me - not part of their job at all, and they were happy to help me with it.  They do have to come inside to listen for something when certain walls are being injected; they were always very polite, wiped their feet and so on.  They worked from 8 to 5 every day, and they did an excellent job of cleaning up after themselves.  The job was planned for two days but took three.  They were very inobtrusive with my renter whose water heater closet they redid.  In fact, they removed some fiberglass insulation near the water heater placed during the water heater repairs not only because it was ineffective but because the type that was there was a potential fire hazard (the paper side was near the water heater).  This is pretty typical of them; they have gone above and beyond on every job for me.  They really do work as if they were insulating their own homes.  Very nice.
The only almost-rough spot is that my cabin and my house had to be drilled right through the exterior siding, and after the holes were plugged, we needed to repaint the house.  The 750- square foot house needed to be painted anyway so I didn't mind, and I planned the big house job to coincide with a painting soon after because I remembered that from last time, and it also was due for a repainting.  Rob tells me that only five houses so far have had to be done this way; but I would ask him before the job if the house will need to be repainted as it would have been a pretty rude shock to not realize this ahead of time.  I understand that most jobs do not result in a repainting, this was about the type of siding we had on our houses.
In fact. Rob offered to supply the labor to restain the plugs to match the siding, but since we are repainting soon, we didn't see any need.
The insulation has been astonishingly effective.  Not only in retaining temperature, but also the houses are now so very quiet.  This has been an excellent investment in our house, and we are very happy with the outcome.  Also, this is a very professional, easy to deal with company.

"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."

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

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.
