Your trusted fire & security partner across Northern Ireland

From the outset, GDC have demonstrated a level of professionalism and reliability that sets them apart. Their engineers carried out a thorough, methodical assessment of our systems — identifying a number of issues that had gone unaddressed by our previous provider. Knowledgeable, personable and exactly the transparent, client-focused approach you want from a fire and security partner.

From the very start the team at GDC presented themselves as complete professionals, engaging with our own maintenance staff to minimise disruption. I've found GDC to be flexible, available at short notice to deal with emergencies, and competitive on the cost of materials and labour — a very important consideration in today's markets.

Excellent service from start to finish. The team were highly professional, knowledgeable and took the time to explain everything clearly. The quality of workmanship was outstanding and the installation completed to a very high standard. I wouldn't hesitate to recommend GDC to anyone.
