Casement Window Repair & Restoration London
London’s older properties are filled with beautiful timber and wooden casement windows but with age comes wear. Rotting sills, sticking sashes, draughty frames and failed seals are all common problems that, left untreated, can cost you significantly in heating bills and eventual replacement costs.
At Restore My Window, we specialise in casement window repair, restoration and refurbishment across London. Whether your timber casement windows need minor adjustments or a full overhaul, our experienced team can bring them back to their original condition, without the disruption and expense of a full replacement.
We provide a fully personalised service tailored to your property. From period Victorian terraces to Georgian townhouses, we have the expertise to handle all wooden casement window types with care and precision.
Maintaining Your Casement Windows
Timber casement windows are particularly vulnerable to moisture if they are not properly maintained. Worn or cracked paintwork allows water to penetrate the frame, leading to timber decay, rot and swelling, which in turn causes sashes to jam and seals to fail.
As part of our casement window repair service in London, our team carefully removes all affected rot and replaces it with precision-fitted hardwood sections, ensuring a seamless finish that matches your existing frames. We take great care to preserve the original character of your wooden casement windows wherever possible.
Our casement window maintenance and repair work includes:
Re-aligning and easing sticking or jammed sashes
Replacing rotted timber sills and frames with hardwood
Reusing original ironmongery, brass hinges, catches and handles, where they are still serviceable
Fitting new locking ironmongery upon request, including modern multi-point locking systems
Repainting and refinishing to protect against future moisture ingress, carried out as part of our residential and commercial painting service
Whether your property has softwood painted frames or hardwood casements, we offer a long-lasting repair that extends the life of your timber windows by decades.
Casement Window Restoration & Refurbishment
For timber casement windows that have been significantly neglected or damaged, our full casement window restoration service is the ideal solution. Rather than ripping out original windows and replacing them with modern alternatives — which can strip character from period properties and diminish their value, we restore them to their former standard.
Our casement window refurbishment process covers every element of the window: the frame, the sash, the glazing, the seals and the ironmongery. The result is a wooden casement window that performs like new whilst retaining the authentic look that makes your property distinctive.
This service is particularly popular with homeowners in conservation areas and older London neighbourhoods, where preserving the original fabric of a property is both a priority and, in many cases, a planning requirement.

Casement Window Reglazing
Alongside our repair and restoration work, we can upgrade the glazing in your existing timber casement window frames, replacing single-pane glass with slim-profile double-glazed units. This means you benefit from modern thermal and acoustic performance whilst keeping the original frames and style of your wooden casement windows completely intact. No planning headaches, no loss of character.
Benefits of double glazing your casement windows
- Noticeably reduces outside street noise — particularly valuable in busy London areas
- Significantly improves thermal performance and energy efficiency
- Enhances home security with upgraded locking ironmongery options
- Easy to maintain — no specialist cleaning products required
- Preserves the original style and character of your timber casement windows

Casement Window Repair & Restoration — Frequently Asked Questions
Common signs include draughts around the frame or sash, sashes that stick or are difficult to open and close, visible rot or soft timber in the sill or frame, cracked or missing putty around the glass, condensation between double-glazed panes, and rattling or loose ironmongery. If you notice any of these issues, it is worth getting a professional assessment before the problem worsens, early repair is almost always more cost-effective than full replacement.
In most cases, repair and restoration is the better option — particularly in older London properties. Original timber and wooden casement windows are often of higher quality than modern replacements, and restoring them preserves the character and value of your home. Replacing windows in conservation areas or listed buildings may also require planning permission, whereas repair work typically does not. Our team will always give you an honest assessment.
