"Did not do work, but pricing was competitive with everyone else.  Invoice got lost in junk e-mail, so did not think I ever received invoice, but I found it a month or so after job was completed again.  If\when I have another job will call All Foam and make sure Invoice doesn't get lost in junk e-mail!

"Summary: Hire them - period! This review has 2 parts: 1) Diagnosis of existing system by Phil, the owner and 2) Removal of old / existing system and installation of new system led by Danny, the lead installer of the FOUR! (4) men on our job. 1). DIAGNOSIS of "Old" System My wife and I bought a townhouse in Greenville and I knew (per the inspection) that the old system was "shot". Consulted seller's realtor for an HVAC Company recommendation as well as Angies List, where I saw the reviews for Energy Sharks. Submitted online contact form and had a call by the owner Phil within the hour. Set up the appointment THE NEXT DAY to inspect existing system. I was not able to be onsite but Phil checked it out and then spent time to explain the issues with the current system, and educated me in PLAIN ENGLISH why the system he recommended, along with the addition of an additional return to help supply the necessary airflow, was what would be needed to provide the level of comfort which we desired. Price was competitive and definitely less than Realtor's referral, who didn't even mention the return / airflow problem. Bottom line, Phil did his job and gave me a quote that I thought was fair (and thousands less than the other quote)... 2). REMOVAL of old system and INSTALLATION of new system. The crew of FOUR (4) MEN arrived at 7:15am and immediately got to work. They put in drop cloths everywhere they would be working and went about their work in a steady manner. A HUGE shout out to Danny, the lead installer. ASK FOR HIM on your job! He kept me constantly apprised of what was going on, where there were some holes in the ceiling that pre-existed, where the new return could be and should be, etc. Can't tell you how competent the entire team was. Each of the men did their part and they worked very efficiently. Less than 4 hours later, they were done. Got a quick tutorial and they were on their way. Summary: Prompt service, fair pricing and excellent communication means I am pleased to refer them - without reservation. Great job Energy Sharks! A+"

"l  spoke with three other solar installation companies and was unhappy with the level of professionalism and the knowledge of the salesperson. I had decided to cancel the idea when I came across Sunpro in an ad. I was attended to immediately, a very impressive assessment was done to analyze the amount of electricity I have been using through the years and exactly how many solar panels I would need to cover my power needs without overpaying for panels that were not needed.
Everything was documented for me in a very professionally done color booklet with all the facts, figures, and graphs that made it very easy for me to understand the entire process, costs, benefits, and etc. During this process I was advised what Government rebates were available for the installation of solar panels AND that if a structure was needed to mount the panels to, rebates might also apply to the cost of the structure. We had been considering adding a patio to our home and Sunpro showed us the benefit of building the patio now which would provide the exact location and angle for the panels to capture the maximum amount of sunlight.
The entire job was done in a surprisingly short time and the quality was superb. The patio (including stamped and colored concrete) turned out beautifully. Frankly, I don't think I have ever been truly satisfied with any work that has been done on my home until this experience. Even the city inspector remarked at the excellent quality of the work that was being done.
In addition, the Sunpro system included making the entire house energy efficient by spraying foam insulation in the attic and sealing the entire house. This extra step (which was never suggested by the other companies) has made an amazing difference in the way the home feels and it allowed for fewer panels needed to provide the power my family requires (saving me money).  I have found out since the installation that Sunpro used certain components in their system that were far superior to what the other companies had advised. These small and inexpensive upgrades have made this system far more efficient than what I had been shown by the other companies.
The owner of Sunpro provided amazing supervision for the entire job. Sunpro also provided ALL the documentation I needed to apply for the rebates and tax credits. Everything was put in an organized folder to give to my CPA. The entire process went perfectly. Since then, Sunpro has done other work for me that has also been done perfectly. I don't know if solar panels are right for everyone, but this is definitely one of the best decisions I have ever made. since the installation, I have not pain an electric bill. In fact, at this time the electric company owes me electricity.
I might add that in my particular case, the entire project costs LESS than what it would have cost me to build the patio alone.
Frankly, it is my policy to NEVER recommend anyone. I have taken the time to write this extensive recommendation only because I am 100% satisfied with the way the job was handled and the quality of the work and materials and the outcome of the entire project.

FAQs for spray foam insulation 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.
