Sash Window Repair & Restoration in Gloucester
We restore original timber sash windows across Gloucester — from the Georgian townhouses near the Cathedral and the Docks to the long red-brick Victorian terraces of Kingsholm, Barton and Tredworth. Our workshop is a short run up the A40, so surveys, joinery repairs and refits happen without the long lead times of a national installer, and almost always without replacing the window.

Period windows in Gloucester
Gloucester's period stock falls into three broad groups, and each fails in its own way. The Georgian and early Victorian townhouses around Brunswick Road, Spa Road and the Docks carry tall box-frame sashes with slender glazing bars and, in the best-preserved examples, original crown glass that is well worth saving. The dense Victorian terraces of Kingsholm, Barton & Tredworth and Wotton have smaller two-over-two horned sashes in soft red brick openings where the sill and bottom rail take the worst of the weather. Later Edwardian villas along Denmark Road and Stroud Road tend to have heavier sashes with deeper bottom rails and, often, decades of paint locking them shut.
Sitting low on the Severn plain, the city gets long damp spells and driving rain on west and south-west elevations. That moisture, combined with pollution and traffic vibration on the main radial roads, is why so many Gloucester sashes are stiff, rattly and rotten at the base while the rest of the frame is still perfectly sound slow-grown pine.
We also get a steady stream of work reversing 1980s and 1990s uPVC replacements. Where the original box frame survives behind the plastic, we can rebuild a matched timber sash and put the correct proportions back into the elevation — usually the single biggest improvement you can make to a Gloucester period frontage.
Rotten sills and bottom rails
Standing water on south-west facing openings rots the sill and bottom rail first. We splice in matched timber rather than replace the sash.
Snapped cords and seized pulleys
Common in terraces where windows have been painted shut for years. New waxed cords, cleaned pulleys and rebalanced weights restore one-handed operation.
Rattle and draught on main roads
Traffic on Bristol Road, Barton Street and London Road makes loose sashes rattle. A routed perimeter brush seal quiets the window and cuts road noise.
Failed uPVC replacements
Plastic units in period openings look wrong and often trap damp in the reveal. We rebuild in timber to the original profiles.

How a Gloucester job runs
Step 1
Free survey
We visit anywhere in Gloucester, open every sash, probe the timber and price the work window by window in writing.
Step 2
Workshop joinery
Sashes come out and travel to the workshop for splicing, new sills and glazing bar repairs; openings are boarded and made secure the same day.
Step 3
Seals and balance
Brush pile is routed into the sash edges and meeting rail, new beads fitted, cords renewed and weights rebalanced.
Step 4
Refit and finish
Sashes are refitted, checked for smooth operation, and paintwork and putty lines made good before we leave.
Conservation areas and listed buildings in Gloucester
Gloucester City Council designates conservation areas across the Cathedral precinct, the Docks, Brunswick Road and parts of Kingsholm, and there are listed buildings scattered through the city centre. In those settings replacing original timber sashes with modern units normally needs consent, while like-for-like repair and internal draught proofing generally do not.
We confirm your property's designation at survey stage, keep the work reversible where the designation requires it, and where consent is needed we prepare the profile drawings and specification for the council so the application reflects what will actually be installed.
