# John Cullerton & Sons Ltd
John Cullerton & Sons is a Durham-based building services contractor specialising in electrical and mechanical installations, maintenance and consultancy. With over 25 years' industry experience, the company delivers comprehensive solutions tailored to commercial and industrial clients requiring integrated building systems expertise.
The firm serves businesses across the North East requiring reliable, professional management of their electrical and mechanical infrastructure. Their clients benefit from a coordinated teamwork approach that eliminates the complexity of managing multiple contractors, instead providing single-point accountability for diverse technical requirements.
What distinguishes John Cullerton & Sons is their breadth of integrated offerings. Rather than specialising narrowly, they provide end-to-end solutions spanning new installations, planned and reactive maintenance programmes, complete refurbishment projects, statutory compliance testing, emergency lighting systems, and fire and security alarm installations. This comprehensive capability means clients can consolidate vendor relationships and maintain consistent standards across all building services.
The company prioritises planned maintenance alongside reactive support, helping clients avoid costly emergency situations through proactive system management. Their consultation services allow businesses to optimise energy efficiency and operational performance. Their emphasis on statutory inspections and testing demonstrates commitment to regulatory compliance and risk mitigation—critical considerations for facility managers.
The business model focuses on reliability and partnership rather than transactional relationships, positioning them as a trusted long-term contractor for organisations serious about maintaining operational excellence.
