Replacement roof windows for old, draughty or damaged VELUX windows.
Specialist VELUX window replacement support for homeowners with ageing, leaking, damaged or poorly performing roof windows.
When a repair is no longer the best long-term answer.
Older roof windows can become harder to use, less efficient and more prone to leaks, draughts, condensation or general wear. In some cases, replacement is the most practical and cost-effective long-term option.
AR Windows helps homeowners understand whether their existing VELUX window can be repaired or whether a replacement roof window would provide a better result. We focus on clear advice, careful fitting and practical solutions that suit the property.
When an older roof window may need upgrading.
Some roof window problems can be repaired. Others suggest the window may be too old, too worn or too inefficient to justify repeated repairs.
Repeated leaks
If leaks keep returning, replacement may be more sensible than repeated short-term repairs.
Draughts and cold spots
Older windows can lose performance over time, making rooms feel colder or less comfortable.
Stiff or awkward use
Windows that are difficult to open, close or lock may be worn, misaligned or beyond economical repair.
Misted glazing
Condensation between panes can indicate failed glazing or reduced thermal performance.
Visible wear
Damaged frames, worn seals, tired mechanisms and old components can all point towards replacement.
Older roof windows
If the window is very old, a modern replacement may improve comfort, reliability and usability.
A replacement roof window can improve more than appearance.
A modern replacement can help restore confidence in your roof window, improve the feel of the room and make the window easier to use day to day.
Better comfort
Improve the feel of rooms affected by draughts, cold spots or older glazing.
Improved usability
Replace stiff, awkward or unreliable roof windows with easier modern operation.
Fresh appearance
Upgrade tired or visibly worn roof windows for a cleaner, smarter finish.
Future options
Consider blinds, solar operation, maintenance support and other roof window upgrades.
Choosing the right route for your roof window.
AR Windows can help you decide whether repair, maintenance or replacement is the most practical route based on the condition of the window.
Repair may be suitable when
Repair may be the better first step if the roof window is generally in good condition and the issue is limited to one part, seal or mechanism.
- The window is not very old or badly degraded
- The issue appears localised and repairable
- The frame and glazing are otherwise performing well
- Servicing or maintenance may solve the issue
Replacement may be better when
Replacement may be more sensible when the roof window is old, inefficient, repeatedly failing or no longer cost-effective to repair.
- The window is old, draughty or repeatedly leaking
- There are major problems with glazing, frame or operation
- Repairs are unlikely to provide a lasting result
- You want to improve comfort, usability and appearance
