Window & Door Repairs & Maintenance
Professional Window & Door Maintenance, Repairs & Replacement
Keep your aluminium doors, entrance systems and windows safe, secure, weather-tight and operating as they should. Dortech Maintenance provides responsive repairs, planned maintenance and replacement solutions for commercial, public and high-traffic environments across the UK.
Protect Performance. Reduce Disruption. Extend Asset Life.
Windows and doors in commercial buildings are under constant pressure. Heavy daily use, poor alignment, failed hardware, broken glazing, water ingress and worn seals all lead to reduced performance, increased risk and avoidable disruption. Our role is simple: identify issues early, repair faults properly, and keep systems operating safely and reliably.
Need support with a fault, repair or maintenance plan?
Whether you are dealing with a sticking door, failed lock, leaking window, broken glass or ageing entrance system, Dortech Maintenance is here to help.

Window Maintenance, Repairs & Replacement
Faulty windows create more than inconvenience. They can lead to safety concerns, drafts, leaks, loss of efficiency, poor security and expensive long-term deterioration. We help building owners and managers restore performance quickly and professionally.
From sticking opening vents and failed restrictors through to broken glazing, failed gaskets and water ingress, our engineers diagnose the issue and recommend the most effective solution.

Planned Maintenance vs Reactive Repairs
Waiting until a door or window fails often leads to greater disruption, higher repair costs and more serious associated damage. A structured maintenance plan helps identify wear early, protect component life and reduce unplanned failures.
Without Planned Maintenance
- Small issues remain unnoticed until failure occurs
- Emergency call-outs and urgent repairs become more frequent
- Misalignment causes locks, pivots and hinges to wear faster
- Leaks and failed seals can worsen and affect surrounding areas
- Security and safety issues may develop unexpectedly
With Planned Maintenance
- Faults are identified earlier and dealt with proactively
- Hardware can be adjusted, lubricated and preserved correctly
- Building users experience fewer failures and less disruption
- Asset life is extended and budget control improves
- Doors and windows remain safer, smoother and more reliable
