H. MOORE AND SON WINDOWS & DOORS REVIEWS

We have lived in our house for 38 years and have always used Moore & Sons for replacing our windows and patio doors and adding windows. Their work is always first rate and the workers are friendly and skilled. This week while I was washing my windows, I inadvertently removed one completely and couldn’t get it back in. I called Moore and Sons, and within 20 minutes two workers were at my house and put the window back in for me, no charge. That is the kind of great service this company gives! Monica and Larry Wade

We Had Windows Installed by H. Moore. They Were Prompt, Professional, Neat, Friendly and Did an Incredible Job. I Would Highly Recommend Them and Am 100% Satisfied. Thanks for The Great Job.Al.

We had H.Moore and Sons install a new entrance door at our house and we were very happy with the end result. The door itself was well made and installed perfectly. The tradesmen that installed the door did an excellent job .

Great job from these guys! From start to finish they were professional in every way!

KD EXTERIORS REVIEWS

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.

Had KD work on two of our houses over the past few years and the work they do is impeccable. Highly recommend them for any exterior work that needs to be done. They cut in a new window for us and you'd think it was always there from when the home was first built in 1912!!

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.
