The Professional Sash Window Repair Process
Professional sash window repair Edinburgh follows a structured, time-tested process that preserves original timber while restoring full functionality:
Step 1: Inspection and Assessment
We inspect every component: test sash cords, check for rot (especially at cills and bottom rails), assess putty condition, measure draughts, and check pulley operation. We provide a detailed report and fixed-price quote.
Step 2: Sash Removal
We carefully remove inner and outer sashes from the box frame, numbering components for accurate reassembly. We protect your home with dust sheets and temporary coverings.
Step 3: Strip Paint and Repair Timber
We remove old paint layers using heat guns and scrapers (never caustic chemicals that damage timber). Minor rot is repaired with epoxy resins. Extensive rot may require timber splicing.
Step 4: Replace Cords and Pulleys
We install new cotton cords on brass pulleys, matching the original weight specifications. We replace worn pulleys and ensure smooth operation.
Step 5: Draught Proofing Installation
We fit brush seals to meeting rails and new parting beads. Quality draught proofing reduces heat loss by up to 80% while maintaining smooth operation. This is one of the most valuable sash window repair Edinburgh upgrades.
Step 6: Re-glazing and Puttying
We replace broken panes with matching glass. For single glazing, we apply new linseed oil putty, which remains flexible for decades. For retrofitted double glazing, we install slim-profile sealed units.
Step 7: Reassembly and Balancing
We reinstall sashes, balance weights precisely, and test operation multiple times. Windows should open and close smoothly with finger-tip pressure.
Step 8: Finishing
We prime bare timber with microporous primer and apply two top coats of microporous paint. Microporous paint allows moisture vapour to escape, preventing future rot.
All sash window repair Edinburgh work is fully guaranteed. We use only traditional materials — cotton cords, brass pulleys, linseed oil putty — to ensure your windows perform perfectly for decades to come.

Not every sash window repair Edinburgh situation is the same. Here is how to decide between repair, restoration, and replacement:
Choose Repair When:
- Broken sash cords only
- Single draughty window
- Localised rot (less than 10% of frame)
- Sticking due to paint buildup
- Windows under 15 years old
Choose Restoration When:
- Multiple problems across the same window
- Windows are 15-30 years old with good bones

- Original timber is sound but neglected
- You plan to stay in the property long-term
Choose Replacement When:
- Extensive rot across entire frame (over 30%)
