"I stupidly let a bubble into my brake lines. I asked for a quote from Direct Tire in Watertown they said it'd cost $128. I went to Diamond Deep and they said 1 hour of labor plus materials came to be $75. That sounds about right for bleeding the brakes. Dropped the car off at 8AM, it was done at 10:30AM same day. The brakes work better than before I even screwed them up. Plus they found a nail in my rear tire and patched it up, which explained why my tire pressure light kept coming on. Overall, a great experience."
"This garage is the best!!! You want to talk about great customer service!! Frank's garage was referred to me by triple AAA since I am not local and had a car problem with an Audi. Frank went above and beyond to help me repair the car (all of this was done over the phone) and fixed the problem in a day only because he insisted he keep the car over night to be sure he repaired it. I was so impressed with his level of service I called Triple AAA back to let them know how pleased I was and to be sure to refer Frank's garage for foreign car repairs. Thank you Frank! you are a gem."
"Known Joel my whole life my father worked for him for years i work in the automotive field and i refere big jobs to Diamond. "
"I have went there the first time for an oil change and figure out an air leak on a tire. Told the person on the counter to check it and if needed to change the tire. When I came back, the person told me the issue was a nail in the tire so they have fixed it for a much cheaper price than if the tire had to be swapped. They have gained my respect, future business and a 5 star review on being honest and cost-effective. Thanks for the great service!"
"Diamond did a great job replacing my brakes. They're fast, convenient, fair and thorough. Management could not have been more friendly and helpful. I'd recommend them to anyone!"
"The service is quick and friendly. I needed new brakes on my car and they were able to get me premium pads and rotors at an incredibly great price. I've..."
