Planned Sash Window Refurbishment for Commercial Buildings
Sash windows are a key feature on many period, heritage and traditional commercial properties. Over time, timber decay, failed paintwork, broken cords, loose putty, draughts and poor operation can make them difficult to maintain. Refurbs delivers structured sash window restoration works that improve the condition of existing windows without moving straight to new installation.

Timber Repairs and Coatings Matched to Each Window
Sound preparation comes before decoration. We assess timber condition, existing paint, glazing and moisture exposure, then specify compatible repairs, primers and finishing coats. Opening edges, joints and moving parts need careful attention so the windows remain usable after painting.

Sash Window Restoration — Common Questions
Can existing timber sash windows be repaired instead of replaced?
Existing sash windows can often be repaired where enough sound timber remains. We assess decay, joints, sills, glazing and operation before recommending local repairs, refurbishment or any sections that need replacement. The aim is to retain serviceable material and the character of the window.
Can draught proofing improve sash windows?
Suitable draught seals can reduce unwanted air leakage and rattling. We first check the condition and operation of the window, then select a detail that allows the sashes to move correctly and suits the building. Any ventilation requirements and heritage restrictions are considered before work is agreed.
Can you repair sash cords and improve opening and closing?
Yes. The proposed work can include replacing failed cords, checking pulleys and weights, easing sticking sashes and adjusting compatible ironmongery. We assess the cause of poor operation before agreeing repairs, rather than assuming every window needs the same work.
What needs checking before work on listed sash windows?
The extent of repair, glazing changes, draught-proofing details and any replacement can affect whether consent is needed. For listed buildings or properties subject to local restrictions, agree the approach with the relevant conservation or planning team before work starts. We can use the agreed requirements when planning the repair scope.
Can sash window restoration be phased around an occupied building?
Work can be phased where access, security, protection and the repair method allow. We agree which windows or areas are available, how openings will be protected and the drying or curing time needed between stages. Temporary restrictions may be necessary while repairs and decoration are carried out.
