GMG carry out planned and reactive maintenance to meet the needs of all our customers, who include the NHS, Network Rail and local housing associations.

With an impressively knowledgeable technical department, every construction problem posed by our clients is met with the same focused determination to find a long-term and low-maintenance solution.

Hardly surprising that 90 per cent of the GMG order book on maintenance is via referral or from repeat clients who know they can rely on our unmatched expertise.

Planned maintenance, also often referred to as scheduled maintenance, is a proactive strategy involving the carrying out of work and inspections at regular intervals to ensure property repairs are anticipated and acted on.

Reactive maintenance is as simple as it sounds – premises are left to operate without interference, and the occupants react to issues as and when they occur, instructing GMG to carry out work.
