Happy Customer
City & State: Silver Spring, MD

I picked Diamond from a garage door manufacturer's website because of its proximity to my zip code. I like to support local businesses. And just 2 days after my initial call, today December 9th, I met with Jon about replacing my house 30 year old garage door. I found him to be a no non-sense straightforward guy who put me at ease immediately. No upselling, no gimmicks! He tells you exactly what you need and immediately offer the best possible price...upfront. I did not hesitate to schedule my installation for Monday the 12th, deciding to move forward without the 2nd estimate I had already scheduled with another company. I knew it wasn't necessary because it was easy to recognize that he is the real deal. Why? No required deposit! He wants to get paid after the job is completed. I believe that policy is indicative of his assurance that I was not going to find a better company or a better price should I choose to continue to shop around! And based on my past experiences I can say with confidence that Diamond Garage Doors is a world apart from many other garage door companies I have dealt with in the not so distant past that have unscrupulously jack up prices because they thought that I didn't know or had no way of knowing how much things truly cost. I was so pleased with my encounter with Jon that I decided to go on a limb here and write this review even before my door got installed next Monday! I will update if anything changes but I don't expect any unpleasantness!

John put in a new garage door for me. He is most professional and competent. I am a happy customer.

Clearly Knows His Stuff
City & State: Fairfax, VA

Cannot say enough about Diamond Garage Doors. Jon clearly knows his stuff. I got a good feeling when talking with him over the phone and things just got better once he came to do my repair. All works great and I highly recommend him and will use him again as needed.

Polite, Professional, Responsive
City & State: Bowie, MD

Jon has been polite, professional, responsive and reliable. He offers advice on the phone and comes out if we aren't able to fix the problem ourselves. He's been a real pro and a pleasure to work with!
Description of work:
We purchased the garage door from Jon in 2014 (which he installed) and he came back today for a service call.

City & State: Bowie, MD

Jon is awesome! I had a bad sensor, and he came out and took care it in a matter of minutes and tuned up my doors. He did not try to oversell me. He is completely trustworthy and I will never use the big stores again. I will always use Diamond!

Was Helpful, Explained Everything
City & State: Ashton,MD

Fixed garage door that wasn't opening properly, did maintenance on both doors -- applied oil, told me why the first door wasn't working properly (which was helpful), and told me that if i needed a tool to fix part of the door, just give him a call.

Member Comments: He did a good job, was helpful, explained everything he was doing so I understood why he was doing it, and gave me some good tips on maintenance of my garage doors going forward. It went well!

Great With Communication
City & State: Ashburn,VA

Took my call in the evening. Had me text him a picture of the garage door and fit me in the very next day. Was very great with communication explaining everything to me and letting me know what was going on and why he needed to do what was needed

They Are Very Good
City & State: Potomac, MD

They are very good. I have used them again. I had to call them up a week ago, but they told me over the phone what to do and I did it and it fixed the thing.
Description of work:
For garage doors, we used a company called Diamond. They replaced one of the motors.

Very Happy with Service
City & State: Chevy Chase, MD

Very happy with service. Jon gave the estimate over the phone, arrived when he said (next day), and gave us a safe system for our toddler. He didn't oversell us on new door, etc., which we appreciated.
Description of work:
Replaced garage door opener (including sensors and keypad) on old very narrow door. Noticed springs were shot so replaced springs and pulleys. So tight they had to figure out how to make the sensors work.

Right away he was able to diagnose the problem. He was so respectful. The price was fantastic. The workers were immaculate, quiet and honest. He gave us a 3 year labor warranty, too.

Efficient, Knowledgeable and Respected My Time
City & State: Washington, DC

Great. Someone wrote, "fast and painless." That about sums up my experience. I would only add that I shopped around a fair amount, and Diamond was by far the best vendor. They are absolutely specialists. Garage door are not just a sideline or a franchise job they read about in a book. From start to finish, they were efficient, knowledgeable and respected my time and wallet, and delivered and installed a quality door on time and within budget.

Would Absolutely Use Him Again
City & State: Silver Spring, MD

We had a wonderful experience and would absolutely use him again, well worth the $$, quality, friendly, fast service! Thank you!!
Description of work:
Jon came right out and fixed and tuned up our garage door even though I called him around 7-730 at night!

Fully Satisfied with the Diamond Team
City & State: Silver Spring, MD

Jon, owner, was very responsive and friendly. He stopped by and gave me a free quote for garage opener (2) installation. Jon was also very helpful in providing a recommendation for openers in case I did not want to purchase the ones he sold. I purchased openers from Sears and Jon's team installed them the next day.
The technicians were fantastic. They were courteous, friendly and talked shop as much as you wanted to. The Diamond team programmed the openers, tested them, provided me with some helpful info for future troubleshooting and removed all the old hardware, after completing an excellent job. Installation was cheaper than what Sears offered and the team was able to install the next day. Fully satisfied with the Diamond Team.
Description of work:
I had two faulty 16 year old garage door openers that needed replacement.

Definitely Would Use this Company Again
City & State: Cabin John, MD

My garage door wasn't working. It was a mistake on my part--I missed a little black lever that somehow had gotten moved. Diamond offered to not charge me for the call (though I would not have figured out the problem on my own--I didn't even see the very small black lever) but I had them do a usual service call on my door. I definitely would use this company again.

Provided Helpful Information
City & State: Kensington, MD

Jon was very responsive - came out to give me a free estimate and returned an hour later to do the work the same day I contacted him. His pricing was fair and he provided helpful information about what might have caused the tension cable to become unattached so that we can avoid that problem in the future.


Description of work:
Reattached tension cable & performed tune-up (tightened bolts, lubricated tracks, adjusted sensor position, corrected position of door when open...)
