Structura UK Ltd is a specialist in high-performance glazed façade systems, architectural glazing and façade maintenance. Our Window & Door Refurbishment service is designed to preserve, repair and reinstate the performance and appearance of commercial windows and doors across retrofit, regeneration and refurbishment projects throughout the UK. Whether glass has been scratched, frames have corroded, or aesthetics have faded with age, we deliver lasting restoration that aligns with architectural intent and technical performance requirements.
What We Do
We provide a comprehensive range of refurbishment works for windows and doors, including:
- Glass repair and replacement
- Frame polishing, cleaning and repainting
- Aluminium, steel or bespoke framing refurbishment
- Resin repairs for chips, cracks and surface defects
- On-site or off-site restoration depending on project parameters
- Colour-match spraying to maintain design integrity
- Detailing and finishing to original or enhanced specification
All work can be undertaken at your site or in our purpose-built facilities, ensuring minimal disruption and maximum control over quality and delivery.
Why Refurbishment Rather Than Replacement?
Refurbishing existing windows and doors offers a number of advantages over full replacement. These benefits are increasingly recognised in the built environment sector as part of sustainability ambitions and retrofit best practice:
Cost Efficiency
Reduces waste and expenses associated with new products.
Preservation of Architectural Character
Particularly important on listed or heritage facades.
Reduced Environmental Impact
Keeps original materials in use and avoids embodied carbon of new units.
Improved Longevity & Performance
Modern coatings, weatherproofing and finishes extend life without losing design features.
Custom Work
For bespoke project needs.
How it Works
This structured approach ensures high-quality refurbishment that integrates with broader façade maintenance or retrofit programmes:
1. Initial Assessment & Specification
We start with a specialist survey of windows and doors to assess condition, defects, corrosion and performance shortfalls. This informs a tailored refurbishment specification.

2. Method Selection – On-Site vs Workshop
Depending on access, condition and project constraints, work can be carried out either on-site or off-site in our controlled workshop facilities.
