• iMac repairs

    Greenwich Communication Centre has been delivering high-quality Apple iMac maintenance and repair services since 2006. Our expert engineers are on hand six days a week to provide cost-effective and speedy solutions to any out-of-warranty iMac computer.

    What we will do to repair your iMac

    When you bring your iMac laptop in-store, our engineers will diagnose the problem and provide a full quote for its repair. We’ll ask you to pay a small fee for the diagnosis, which will be deducted from the final repair costs.

    As well as fixing the immediate problem, we’ll give your laptop a full check-up to make sure it is up-to-date and running effectively. This will help prevent faults from occurring in the future. All our work is guaranteed for quality. Any recurring problems will be fixed at no extra charge.
