A Collaborative Approach That Delivers
More Than a Contractor — A Reliable Partner for Complex Commercial Environments
We understand that commercial clients need more than a one-off service provider. You need a dependable partner — one who delivers consistent quality, respects your operational pressures, and works in full compliance with health, safety, and industry standards. That’s exactly what we offer.
Our approach is shaped by years of experience working across schools, hospitals, office blocks, warehouses, and retail environments. We know that in these settings, door and window systems aren’t just infrastructure — they’re critical to access, safeguarding, compliance, and the smooth running of your organisation.
Understanding Your Environment
No two commercial buildings are the same — and neither are the risks, routines, or regulations that govern them. That’s why we start by understanding your environment.
Whether we’re working in a school where safeguarding is paramount, a hospital that demands sterile working and noise control, or a warehouse that can’t afford even an hour of downtime, we tailor our approach to fit. We’ll consider how people move through your space, where key risks lie, and what times and methods will cause the least disruption — planning carefully so that safety, access, and performance are never compromised.
Clear, Responsive Communication
Time is money, and clarity is key — especially when dealing with critical building systems. From the moment you contact us, we keep communication clear, prompt, and professional.
We provide detailed, line-by-line quotations, confirmed booking slots, and progress updates throughout. You’ll always know what’s happening, when, and why. If something changes, we let you know straight away — no delays, no chasing, and no last-minute surprises.
Compliance and Quality First
Commercial buildings are subject to strict regulations — from fire safety and accessibility to safeguarding and data protection. We understand the importance of compliance, and we never cut corners.
Every project we deliver is completed in line with current legislation and industry best practice. We provide full documentation — including risk assessments, method statements, warranties, and compliance certificates — and our work is designed to stand up to scrutiny from inspectors, insurers, and internal audits alike.
Minimal Disruption, Maximum Reliability
We know how disruptive faulty doors, non-compliant fire exits, or failed access systems can be — and we know how important it is to get things resolved without affecting day-to-day operations.
That’s why we work around your schedule — offering flexible appointment slots, out-of-hours works, and phased delivery where needed. Whether it’s a one-off repair or a large-scale installation, our aim is always the same: to get the job done safely, properly, and with the least impact on your business.
Commercial Installations
Supplied and installed with care. Engineered to last.
We supply and install windows and doors designed for high-use, safety-critical environments. From secure school entrances to automated retail and office entryways, our solutions ensure durability, performance, and full compliance with fire, safety, and accessibility standards.
Working across education, healthcare, retail, warehousing, and office settings, we deliver installations that balance security, functionality, and visual quality. Every product is carefully selected for compliance and durability, with the entire process — from specification to installation — managed in-house.
Our services include aluminium and uPVC window systems, fire-rated doors (FD30, FD60+), and manual or automatic entrances for high-traffic areas. We also install vision panels, anti-finger trap systems, motorised or high-level windows, and acoustic or thermally-rated units for energy efficiency and noise control. All installations are carried out with professionalism and precision. We provide site-specific RAMS, work flexibly around your operations, and ensure a high-quality finish with minimal disruption to your staff, service users, or customers.
Repairs & Make-Safe Services
When safety, security, or access is compromised — we respond fast.
We understand that when a door fails or a window is damaged in a commercial building, it’s more than an inconvenience — it’s a risk to safety, security, and business continuity. That’s why we provide a rapid response service to secure your premises quickly and minimise disruption.
We work with a broad range of commercial clients — including schools, hospitals, retailers, warehouses, and office-based organisations — delivering urgent on-site repairs and professional make-safe services. Whether addressing a compromised fire exit, damaged shopfront glazing, or forced entry to a logistics hub, our experienced engineers respond with precision and care.
Our service covers a wide range of issues, from failed glazing and misaligned doors to malfunctioning automatic systems and defective locks, hinges, or closers. Where immediate repair is not possible, we implement temporary safety measures such as boarding, safety film, or temporary hardware to reduce risk and restore security. Once the site is made safe, we provide a clear, itemised quotation for remedial works — outlining materials, labour, and lead times to support swift, informed decision-making.
Maintenance & Service Contracts
Prevent costly failures. Protect long-term performance.
We offer proactive maintenance services to keep your commercial doors, windows, and access systems operating safely, smoothly, and in full compliance. For environments where safety, security, and continuity are critical — including schools, hospitals, offices, warehouses, and retail spaces — regular servicing reduces the risk of failure and extends asset life.
Our planned maintenance includes scheduled checks on manual and automatic doors, motorised windows, and ventilation systems. We inspect and adjust fire doors, carry out accessibility spot checks, and manage all documentation — including service logs, maintenance reports, and asset registers — to support audits, insurance, and estate planning.
We tailor maintenance plans to suit your operational needs, offering term-time visits, infection-control scheduling, or out-of-hours servicing as required. With GC Doors as your maintenance partner, you minimise reactive call-outs, maintain compliance, and keep your building running without disruption.
Commercial Glazing
High-performance glass systems for visibility, safety, and privacy.
We deliver tailored glazing solutions for commercial and public-sector buildings — including hospitals, schools, offices, and retail spaces. Our installations are designed to enhance safety, support accessibility, control sound, and elevate the appearance of your building, all while meeting relevant compliance standards.
Our installations include fire-rated and laminated safety glass for high-traffic areas, acoustic glazing for noise-sensitive spaces, and privacy options such as frosted, obscured, or switchable glass for education and healthcare settings.
For retail and commercial environments, we offer shopfront and curtain wall glazing that combines clean, modern aesthetics with durability and thermal performance. All systems can be integrated with DDA-compliant doors and screens to ensure full accessibility.
Access Control & Accessible Entry Systems
Secure, inclusive access — tailored to every user.
We provide secure, compliant, and accessible access control and automated entry systems for commercial and public-sector buildings — including schools, healthcare sites, retail units, warehouses, and public facilities.
Our services include intercoms, fob and keypad entry, and automatic door openers with push pads or sensors — all designed to support fire safety, accessibility, and efficient operations. We install DDA-compliant systems for inclusive access and touch-free solutions for hygiene-sensitive environments. From main entrances to restricted zones like plant rooms or staff-only areas, our systems are tailored to your operational needs. All installations are compatible with fire alarm systems and emergency overrides, and include full user training to ensure safe, confident use.
