"He repaired cracked granite countertop and matched it perfectly. He then sealed and polished countertop. Found him to be very professional. Will definitely call him again."

"AGS was fantastic to work with, from Todd, the salesperson who came to my house, all the way to Luke who delivered a sink grid to replace the incorrect one I originally received. I had contacts with so many of the employees of AGS (Baris, Oscar, Baran, Tiffany, and more whose names I don’t remember) and each one was thoughtful, knowledgeable, helpful, and friendly. Their customer service is top-notch. I had a few minor glitches that were attended to immediately (e.g., the sink grid). I went to the showroom so I could actually pick out my granite stone. It was not a close ride but definitely worth it. The office staff and even the employees in the back with the stones could not have been more helpful. The "showroom" is really nice with lots of granite and quartz to choose from. I LOVE my new countertops, sinks, and faucet. I will definitely be recommending AGS to any of my friends who are in the market for new countertops."

"Pat and his team did great work all around. My basement is dry for the first time and has stayed dry since the work. Stone pointing was done right by shaving down old cement before pointing. Chimney looks great! I would definitely recommend Quinn Brothers for mason work and basement waterproofing."

"John did great work. He tiled my basement kitchen and two bathrooms. Prep work and final work product were top notch at reasonable prices."

"Beautiful job! The kitchen counters have nevaska granite, and perla venata quartzite for the kitchen bar. Went in one Saturday, founds the ones we liked, took samples home to test for staining, etching, scratches - both passed with flying colors. Went back the next Saturday to pick our slabs, they came and measured, went back for placement on the stone and they installed the following Friday. They were in and out in a little over 2 hours. Very nice bunch of guys who did a beautiful job, didn't break or ruin anything - it was a pleasure to have a job run smooth and everything look better than when they came. We love the new stone, it looks like we have a bigger kitchen and the stone is so beautiful - we couldn't be happier. I would definitely recommend KOL - they have an extensive selection, will answer ALL the questions you may have, and do a wonderful installation."

"After repair work was done, the shower is like new. The shield prevents the buildup of soap scum, making cleaning easier than ever. Also had my granite counters sealed. This is a great product, and the service I received was top notch."

"Everything went as expected and very well. We have had it for 5-7 years and I have no stains or scratches on it."

"The representative at the office explained everything about the install including the time frame. Everything went smoothly form the choice and approval of the slab, to the measurement and installation. Everything matched the time frame on the schedule and everything was done efficiently, from measuring to plumbing to old counter top removal and disposal to installation. I am thrilled with the outcome and would choose Colonial Marble and Granite for any future project."

"Niko and Walt did an excellent and professional job of tearing out and installing a new backsplash in our kitchen and tile floor in our laundry room. The work was done promptly, clean and at a reasonable price. Will definitely use them again in the future if needed."
