AWM Windows provides professional skylight and roof window glass replacement services for homes across London and surrounding areas. If your skylight glass is cracked, misted, leaking, cloudy or no longer insulating properly, we can assess the problem and recommend the most suitable solution.
In many cases, the full skylight or roof window does not need to be replaced. If the frame is still in good condition, we may be able to replace only the failed glass unit, helping to restore insulation, appearance and performance at a lower cost than full replacement.

We replace cracked, broken, misted, and failed glass units in skylights where the existing frame remains in good condition. This service restores clear visibility, improves insulation, and helps reduce energy loss. By focusing on glass replacement instead of a full skylight installation, you can save costs while extending the life of your current skylight.
Our roof window glass replacement service is ideal when the frame is still structurally sound. We install high‑quality glazing that enhances thermal efficiency and restores natural light to your space. This option avoids the expense of a full roof window replacement while ensuring long‑lasting performance.
We provide replacement glass solutions for VELUX‑style and similar roof windows, tailored to fit perfectly with your existing frames. Upgrading the glass can improve insulation, reduce condensation, and restore clarity. This ensures your roof windows continue to perform well without the need for a complete unit change.
Failed double‑glazed units often show condensation or cloudiness between the panes, reducing visibility and efficiency. Our misted glass replacement service restores clarity and insulation, helping to maintain a comfortable indoor environment. This cost‑effective solution avoids unnecessary full window replacements.
Damaged skylight or roof window glass can compromise safety and energy efficiency. We safely replace cracked or broken panes with durable, high‑performance glass. This restores both the security and functionality of your windows while preventing further damage to the frame or surrounding structure.
Our inspection service checks the condition of seals, frames, and potential leak points around skylights and roof windows. Identifying issues early helps prevent costly water damage and ensures your glazing performs at its best. We provide clear recommendations for repairs or replacements to keep your property protected.


In many cases, the issue is with the glass unit rather than the full skylight or roof window. If the frame is structurally sound, replacing the glass may be the most practical and cost-effective solution.
However, if the frame is badly damaged, rotten, warped, leaking due to roof or flashing issues, or no longer suitable for repair, a full replacement may be recommended. AWM Windows can assess the condition and advise on the best option.
For a faster quote, customers can send us clear photos of the skylight or roof window from inside the room, close-up photos of the damaged or misted glass, and any visible label, code or manufacturer details if available.
If possible, please also include the approximate glass size and the property location. This helps us provide a quicker and more accurate estimate.
