Fast, reliable service. They explained the work while they were doing it and got us back in business quickly. Price was reasonable and they were able to come out in just a few hours. Won’t hesitate to call them again!”

My experience with Diamondback was wonderful! From the receptionist/scheduler, Tina, to our technician, Paul, our service was prompt, friendly and professional! 5 stars from this homeowner!”

Jessie Silvers

I called and got a friendly and prompt response. They listened to our problem and current situation and we’re accommodating to both! The technician was very polite and professional! He was up front with us about the situation and the cost and wasn’t pushy about what we should do. He gave us the information and let us make our own decision. We will definitely use them again!”
