Get matched with top stone restoration & polishing pros in Wilmington, DE

"My slate floors look great after having them refinished and polished. Would highly recommend."

"I LOVE my 2 newly renovated bathrooms. Jeff did a beautiful job tiling my new shower, building me a linen closet, and installing a new bathtub, shower system, shower door, and fans. He is great to work with, very fair and has a lot of integrity. I highly recommend him. I made an awesome pick!"

"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."

"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 was perfection! He was on time and very professional. I had to cancel on him in December 2017 and I called him back to reschedule in March 2018, we set up install for April. He called me back a few days later with an opening for yesterday, 3/14/18 I was so happy he thought of me to call for the opening! He covered my floors and was so quiet I did not even know he was there. He cleaned up everything that you could not even tell he was there. I highly recommend this company to everyone! You will not be disappointed. I love my kitchen back splash. Thank you, John."

"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."

"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."

"Very detailed & quality craftsmanship. I would not hesitate to hire for additional projects."

"Excellent job done in timely and professional manner fence look great!! Wife very happy"
