- Aluminium windows and doors
- Balcony and patio doors

- Replace damaged glazing beads where required
- Repair and maintain traditional sash windows, including cords, weights, pulleys and associated components
- Carry out sealing and perimeter silicone works internally and externally
- Make good around installations following window or door replacement
- Take accurate measurements for replacement windows, doors, glazing and components
- Identify suitable replacement parts and assist with sourcing materials
- Produce clear site reports, photographs and recommendations following inspections
- Provide accurate information for quotations and identify the most cost-effective repair solution
- Communicate professionally with residents, landlords, property managers and clients
- Ensure all works comply with relevant health & safety requirements and industry standards
- Keep work areas clean, safe and tidy and remove waste upon completion
