"I was very pleased with Home Genius Exteriors, and would highly recommend them to all friends and family. Jimmy was honest and very professional, and seemed to really know about roofing and all the types of shingles. And how to properly correct the leak I was having."

"I received the best estimate from Chris with Koala Insulation of the midlands. Chris guided me every step of the way from answering every phone call and every text message at any time. Chris was very thorough in his work and providing me the best quote I have received. I highly recommend Chris and koala insulation. I am very happy with my results and their work!"

"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."

"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.

"Like anyone that notices their home is starting to crack and move you feel overwhelmed. After hiring a structural engineer to tell us what what was going on we began the search for a foundation specialist. I interviewed three companies and after research selected CNT Foundations.
We are very happy with the outcome. They met all my criteria and deserve this recommendation. I expect excellence, attention to detail and integrity when I pay for a service. Victor and his three man crew met all these standards. I was kept informed, involved and allowed to observe what they were doing. The job site was left clean, my home was not damaged and the job was finished on time. Victor was on onsite to supervise every phase of the operation and address my questions. There was immediate follow-up to see if I was satisfied and I my account was adjusted when the cost of the service was less than expected. Before you go with a company that advertises on TV everyday give these guys a try. You will be glad you did.
