"Jeff and his team are amazing. Reasonably priced and the quality of their work along with thoroughness is outstanding. He was clear with what he will do, took pictures along the way. One day when I was at work, he also sent me videos of the work showing that the newly installed sump pump is working, etc. Very professional. I will recommend and hire Jeff and his team in a heartbeat next time I need such a service."

"We used Tri Stone to install all-new siding on our house in Graniteville and couldn’t be happier with the transformation. The house honestly looks completely different now. Everything was fitted neatly, the crew cleaned up after themselves and the whole project was handled very professionally. We’ve already had people comment on how much better the house looks. Great work."

"Arrived on time and an did excellent job and cleaned up the entire site."

"Went above and beyond to help us with our brick wall and floor in our shed. They installed a pump for the water and repaired the wall. The helped us with some other things in the shed that we asked for the day of as well. Overall really great work and professional. We will use them again and would highly recommend."

"We contacted many contractors and Nelson was the most competitively priced. We are so glad that we choose Nelson because his crew worked tiredlessly to complete the job during Covid. You can tell that Nelson has been doing this for a long time because the timing and estimated completion date was on point. He is reachable and contantly kept us up to date. You can definitely rely on him. Nelson was on site nearly everyday to make sure that our patio pavers were installed perfctly. Nelson also worked with us closley to ensure that our custom bench was built as designed and it came out perfectly. He helped us locate custom pavers that were not readily available due to the shortage of materials caused by the pandemic. I would recommend his services to anyone."

"Our experience with C&G was extremely positive. Guy was completely above board about everything, throughout the process. We inherited a mold problem from a previous owner and he walked us through the process, adhered to all state guidelines (including ensuring that independent parties did the testing and restoration work after C&G did the remediation), and did a fantastic job taking care of the problem. He also helped us out with an entirely separate water issue one day when he was in the neighborhood. We are huge fans and would recommend him to anyone."

"We had been living in our house for 5 years and although the kitchen was a new addition, every winter my wife & I had noticed how noticeably the temperature differentiated especially after the winter of 2014/15.  And because it was a dirt floor with some wood and old construction debris strewn about.  I was not so keen on staying down there.  In doing my own investigation there was some piping and insulation under floor.
So when investigating estimates we called a number of "green" companies.  Out of the three companies that came, only Frank Petrullo with Eco Green Solutions, noticed the mold and a water leak coming from fridge line.  He took the time to show me where the water was coming, how mold had proliferated on the wood floor joists and beams.  The dirt floor was somewhat moist and light was visible from outside along foundation rim contributing to the mold and moisture in crawl space.  He explained each of our options and detailed the steps in sections of each estimate.
We opted to have a plumber fix the water leak, then franks crew came in, cleaned up the mold, then layed down the crawl space membrane, finally insulating floor & rim joist.  All in under two days.  The crew showed up on time, left the open sections of the house clean, and we immediately noticed a difference in kitchen and rest of house.  Walking around bare foot in kitchen is more comfortable, the kitchen is less noisy, and house humidity is maintained.

"When we moved into this old Victorian we didn't realize we would have a problem with water showing up in our basement every time we had a big rain.
I called A-1 and another company to consult on the problem.  They, of course, were very familiar with this problem and recommended a french drain system into a sump with appropriate pumps to send the water outside.  The salesman (Bob) did a great job of explaining what they would be doing, the materials, and their knowledge of working on old houses.
Because of the vintage of the house (1901) it's a little tricky installing the french drain; normally you put the drain right at the base of the foundation wall; because the foundation in old houses are relatively fragile, you need to put the drain about a foot away from the wall and add a plastic liner to ensure water coming in at the base of the wall is channeled into the drain system.
I liked both company's proposals but decided to go with A-1.
Their crew (maybe 8-9 guys) showed up right on schedule to start 4-day job.  Initially, the foreman thought it might take 5 days but they were able to finish in 4.  I must tell you this was a huge, messy job BUT they did a great job of minimizing the impact on our house.  They helped us consolidate all of our stuff in the center of the basement, built a plastic barrier to protect it, then went to work.
They outlined the location of the drain line and the sump, then began jack-hammering which lasted two days (no napping in our house during that time).  They broke up the basement floor to dig the trench; that left a huge amount of debris to haul out, one 5-gallon bucket at a time.  They lined the trench with the appropriate fabric, then drain rock, then installed the drain pipe. They dug the sump and installed the 2 sump pumps and connected the whole interior system. They drilled through the wall to get the pump output line outside and trenched the line about 40 feet into the yard where they dug a dry well.
Then the finish work: mixing concrete and covering over the drain pipe in the basement. When they finished it was almost as though they hadn't been there. The basement looked as good as before; the yard (and our new landscaping) was undisturbed.
What I especially liked was the things they did to go over and above--things I wouldn't have thought to ask about: they removed a couple of brick columns along the wall that were leftover from now removed waste lines; they added two access drain lines tied into the main system for things like a dehumidifier.
I am very satisfied with all of their work--I definitely got my money's worth. So far, we have a dry basement.

"I am very relieved! A day or two after my foundation crack was sealed a brutal storm occurred.  I'm happy to report that there was not one drop of water in my basement."
