    We bought a Townhouse in Maryland and the fourth week here, the garage door spring broke. My neighbor across the street recommended ADP Garage Doors. I called late afternoon. And by 7p Jacob the technician was here. It would have been fixed right then, if not for the fact that the spring I needed had to be cut. He returned the next morning by 11 o'clock with the new spring. It's installed, works fantastic. He corrected three other problems while here. Thanks Jacob! I was expecting a 3 day project and it was done in hours.

    I called ADP Garage Door, a locally owned business, on Saturday evening. The owner, Dima, answered and confirmed that I did not need to use the 24-hour emergency service. He scheduled a technician for Monday morning between 9:00 and 11:00 a.m. At 7:00 a.m. Monday, I received a text confirming that technician Jake Hoffman would arrive during that window; the message also included his photo. Jake arrived on time, was pleasant and professional, and completed the repair before noon. The price was fair, and communication was excellent throughout the process. The company’s website lists prices for most standard services, and my invoice matched the posted price exactly.

    Highly recommend this company!! Jake was open, honest, and helped me!!! I didn’t feel taken advantage of which is rare these days. The install was quick and easy! 😊👍🏼

    My garage door suddently failed to open. I called several local companies, but ADP offered the quickest service. Dima and his team came about two hours after I placed my call. Dima immediately diagnosed the issue (broken spring) and within an hour I had a functionning garage door again. The guys who worked on the repair were very pleasant and professional and I would not hesitate to use this company again in the future.

    What an outstanding company. I've had door services done in the past. Jake went way above and beyond. He figured out that the tracks were not level on my garage door and leveled things out. I had noticed the door closed on one side first but didn't realize how serious of a problem that was. He also resolved some noise problems we were having. A+ service start to finish....Jakes was extremely detail oriented and did much more than I expected. I will only use ADP in the future for my garage needs.

    I called in because my garage door was not opening properly and it was also very heavy when I was trying to open it myself.
    Their technician named Jacob came out the same day and was able to fix the problem and get the door running way better than I thought it would. and he was very knowledgeable about garage doors and just a good guy to talk to all around.
    He also gave me a range of options for what kind of service he could do from a complete replacement down to just a basic fix for my existing garage door which I appreciate.
    I'm very happy with the work he did and the price seemed reasonable to me.
