Heritage Joinery Services in Cheltenham
All work is carried out by master carpenters and joiners equipped for both precision on-site repairs and off-site workshop fabrication. From sash window overhauls to period front doors, casements, French doors and original shutters, every job is specified for conservation areas and listed buildings across Cheltenham and Gloucestershire.
Our combined workshop joinery and on-site carpentry capability allows us to custom-craft bespoke timber sections off-site while completing seamless, clean installations at your property.

Sash Window Overhaul & Draught Proofing
A full sash overhaul takes the window apart, frees sticking sashes, renews broken cords, rebalances the weights and services the pulleys so both sashes glide and lock properly again. Discreet brush pile seals are then routed into the staff beads, parting beads and meeting rail.
The result is a window that stops rattling in a Cheltenham westerly, loses far less heat, and looks exactly as it did from the street. Nothing original is thrown away where it can be repaired, and all work is carried out by master carpenters and joiners on site.
- 100% conservation compliant — no change to external sightlines
- Up to 80% reduction in window draughts and rattle
- Renewed cords, weights and pulleys with smooth operation restored
- Typically 10–15 years of service from the brush seals

Heritage Slimline Double Glazing
Slimline double glazed units are fitted into your original timber rebates, so the frames, glazing bars and putty lines stay as they are. Units are specified to suit conservation areas and listed buildings, with heritage glass options where an authentic reflection matters.
Each sash is dismantled in our workshop, the rebates carefully deepened where required, and the glazing bedded and finished in linseed putty before refitting on site. Thermal and acoustic performance improves dramatically without losing a single original moulding.
- Fits inside original frames — no replacement windows
- Conservation-grade slim units with heritage glass options
- Significant heat retention and noise reduction
- Linseed putty and microporous heritage paint finish

Timber Rot Repair & Sill Replacement
Decayed sills, bottom rails and cills are cut back to sound timber and spliced with matched Accoya or Sapele rather than filled or replaced wholesale. Joints are scarfed, glued with marine-grade resins and pinned so the repair outlasts the surrounding timber.
Only where more than roughly half a member has failed do we make a new section — in which case it is reproduced to the exact original profile in our workshop and installed cleanly at your property.
- Accoya & Sapele timber splicing with a 50-year rot-free guarantee on Accoya
- Original profiles matched exactly for conservation areas
- Marine-grade epoxies and traditional scarf joints
- Far cheaper than full window replacement

Period Front Door Restoration & Porticos
Specialist repair, timber splicing and weather-sealing for Georgian, Victorian and Edwardian solid timber entrance doors, fanlights and the surrounding timber porticos. Dropped doors are re-hung, worn rebates rebuilt and weather bars renewed.
Mouldings, panels and fanlight bars are reproduced in our workshop when original sections are beyond saving, then painted in microporous heritage paint. Ironmongery is serviced or sympathetically replaced so the door closes and seals as it should.
- Georgian, Victorian and Edwardian door expertise
- Fanlight, architrave and portico joinery reproduced to match
- Weather-sealing and draught exclusion without altering character
- Brass and period ironmongery serviced or renewed

Timber Casement Window Repairs
Draught-proofing, rot removal, hinge servicing and frame alignment for traditional wooden casement and cottage windows in conservation areas. Binding casements are eased and re-hung, and corroded hinges and stays are replaced with period-correct hardware.
Perimeter seals are fitted discreetly into the rebate so the window closes tight against wind and rain. Decayed bottom rails and cills are spliced in matched timber and finished to suit a Cotswold or Cheltenham conservation setting.
- Draught and noise reduction with concealed seals
- Hinge, stay and catch servicing in period-correct hardware
- Rot removal and matched timber splicing
- Suitable for conservation areas and cottage properties

Timber Bifold & French Door Rot Splicing
Surgical removal of decayed bottom rails and stiles on glazed patio, bifold and French doors. We cut back only to sound timber and splice in durable Accoya or Sapele, sealing with marine-grade epoxy resins to save the existing door set.
Doors are re-hung, tracks and hinges adjusted and the threshold weather-sealed, so the set runs smoothly again. This is routinely a fraction of the cost of a replacement glazed door set, with no disruption to the glass.
- Saves the existing door set — no full replacement
- Accoya & Sapele splicing with marine-grade epoxy
- Tracks, hinges and thresholds realigned and sealed
- Existing glazing retained wherever possible

Heritage Shutters & Interior Window Joinery
Precision repair and restoration of original internal timber folding shutters, architraves, window sills and internal timber linings. Painted-shut shutters are freed, knuckle hinges serviced, and missing leaves reproduced to match the surviving panels.
Interior joinery is finished to a decorator-ready standard, with mouldings run in our workshop to copy the originals. Working shutters add a genuine layer of insulation and security to a period room.
- Painted-shut shutters freed and made fully working again
- Missing leaves, architraves and linings reproduced to match
- Extra insulation, blackout and security for period rooms
- Decorator-ready finish in heritage paint systems
