Having new doors or windows installed is a major investment in your home — one that impacts your security, energy efficiency, comfort and kerb appeal. At GC Doors, we ensure that investment delivers long-term value with professional installation services that are clean, careful, and built to last.
Whether you’ve purchased products from us or already have your own, we’re here to help. We offer both supply and installation, as well as installation-only services for homeowners who need expert fitting for products they’ve sourced themselves. Either way, you’ll benefit from our same high standards, expert workmanship, and full compliance with UK regulations.
We understand that installation work can feel disruptive — especially in a busy home. That’s why we operate with one guiding principle: we treat your space with the same care and respect we’d expect in our own. From protecting your floors and furniture to leaving every area spotless when we’re done, our installers work efficiently, respectfully, and with your comfort in mind. We don’t rush. We don’t cut corners. And we never leave until the job is done right.

Preventative Maintenance for Long-term Peace of Mind
When safety, security, or access is compromised — we respond fast.
Some repairs can be avoided altogether with the right care. This is especially true for older properties or homes in high-traffic areas, exposed to harsh weather conditions or constant wear and tear from daily use. At GC Doors, we offer preventative servicing plans designed to help you stay ahead of common issues — saving you time, stress and unnecessary costs in the long run.
Our preventative maintenance includes routine checks on key components such as hinges, locks, seals, glazing and ventilation points. These subtle yet essential parts of your windows and doors often show the first signs of wear, and early intervention can make all the difference. By identifying and addressing small problems before they escalate, we help you avoid expensive repairs or premature replacements.
This kind of proactive care not only extends the lifespan of your existing installations but also improves day-to-day functionality. Doors open and close more smoothly, windows seal more effectively, and your home stays better insulated — which can help lower energy bills and improve overall comfort. It’s also a smart way to protect the value of your home, ensuring that everything remains safe, compliant, and in excellent working order. Because at GC Doors, we understand it’s not always about replacing everything. Sometimes, it’s about restoring what you already have and making sure it continues to serve you well for years to come.
Residential Maintenance & Repairs
Small Fixes. Big Difference.
Even the best-fitted doors and windows can develop issues over time — hinges begin to creak, seals wear out, locks become stiff, or glass starts to mist. Left unresolved, these minor faults can compromise your home’s energy efficiency, security, and comfort. At GC Doors, we offer responsive and reliable residential repair and maintenance services to keep your doors and windows performing at their best. Whether it’s a one-off issue or part of your long-term home upkeep, we deliver fast, effective solutions with minimal disruption.
We understand how frustrating it can be when a window won’t open, a door won’t shut properly, or a lock starts to fail. That’s why we aim to resolve most issues in a single visit — giving you back your peace of mind, and your property its full functionality.

Stiff or sticking doors and windows. Broken or worn-out handles, hinges, locks and latches. Damaged or cracked glass, including single, double and triple glazing.
