KD is 5 star group. Very fair pricing, first class workmanship. I would use them again.
Joe Brander
Friendly staff and very clean. They have bird baths, fountains, fireplaces, windows, doors and so much more. We were invited as a vendor for a craft show there and it was fun. They had hot dogs, pop, candy floss, baked goods. I would highly recommend going and checking this place out if you plan on doing anything for your home or redecorating it with anything for the outdoors. The bird baths are gorgeous along with all the many cement sculptures they have also. Beautiful work.
Tino Ruffolo
Great company and great workers. Even in bad weather, the crew was slugging it out. Our house looks brand new. Great workmanship. They answered our call right away while other companies did not respond. I highly recommend this company.

Made an appointment for a quote. He didn’t show, I called and finally showed 90 min later. Was personable when he finally showed and took measurements. He told me he would have quote to within a cpl of days. Two weeks of not hearing anything, I called. He apologized and told me my quote would be ready the next day. It’s been a month and still no quote. I feel that if they didn’t want my business he should have just said that and not wasted my time.
