Rapid Response to Repair Requests (866-847-5500)

Granite offers around the clock and coast-to-coast repair service 24 hours a day, 7 days a week, 365 days a year. Our network of licensed and bonded technicians can be anywhere within 4 hours. For all repair calls, it is our goal to provide a status call back phone call within 1 hour of the customer’s initial repair call.
When you have a problem, we don’t ask you to go to a website to find the solution online. We ask that you give us a call and speak with one of our live, repair representatives who will help you solve the problem. If you need repair service, our repair representative will schedule an appointment for you, or have a technical crew dispatched to your location within minutes of your call.
The Granite difference is built on providing unparalleled customer service on each and every call, for each and every customer, which means earning your trust on every call, every day. We answer immediately and work with you to resolve your issue as soon as possible.
