Customer Reviews

★★★★★ Kathy L. - Silver Spring, MD
John put in a new garage door for me. He is most professional and competent. I am a happy customer.

★★★★★ Jetty Viot - Gaithersburg, MD
He did a good job and got the door fixed. His prices were reasonable and he seemed very experienced. When I initially called him, he was able to tell me over the phone how to get my door opened so I could leave to go to work. Then in the evening he came and actually repaired the door.

★★★★★ David G. - Kensington, MD
Jon was great. I bought a new opener and system and he installed. Showed up on time, price was right, and he made some recommendations on the best type of system to buy at my local Home Depot. A+ all around.

★★★★★ James Boyd - Silver Spring, MD
Jon Rosenthal was amazing. I realized one of the springs on our garage door had broken around 11:30 am. After doing some research on Angie's List I called Jon at 12:30 pm. I explained the problem to him including the inability to open the door even when disconnected from the door opener. Jon indicated he had a full schedule that day but would fit me in since our house was on the way home. He gave me a fair price and a time (7-7:30 pm). Jon and his assistant arrived as promised and replaced both springs on the double door. They also lubricated all the rollers which significantly quieted the operation of the door. They were done in about 30 minutes. I was very appreciative Diamond Garage Doors went the extra effort to fix our door that same day. Awesome customer service!!!
