Sash Window Repairs Hampstead
Sash Window Repairs in Hampstead, NW3
Block Restoration repairs and restores timber sash windows in Hampstead, from single flats to whole mansion blocks. Most buildings here are Georgian houses, red-brick Victorian and Edwardian villas and mansion blocks, many in conservation areas, and their original sashes are worth saving. Every job starts with a proper inspection, because the right repair depends on finding the cause, not just the symptom.
Common Problems We See on Hampstead Buildings
Hampstead’s older brick buildings sit on clay, so movement cracking is common, along with soot-stained and eroded brickwork, failed pointing and timber windows that have taken decades of weather on exposed, hilly sites.
Our Sash Window Repairs Services in Hampstead
- Full sash overhauls: removing the sashes, freeing and easing them, renewing cords and pulleys, and refitting so they run smoothly.
- Rot and timber repairs: cutting out decayed timber and splicing in new wood or resin repairs, keeping as much original material as possible.
- Draught-proofing: fitting brush-pile seals and new beads to stop rattles and draughts without changing how the window looks.
- Re-cording and re-weighting: replacing broken sash cords and balancing weights so windows stay open where you put them.
- Glazing and putty: replacing cracked panes and failed putty, and slimline double glazing where planning allows.
- Redecoration: preparing and painting in microporous paint as part of a planned external decoration cycle.
How We Work
- Inspection and survey: we look at the building close up, photograph defects and identify what is causing them.
- Itemised specification and quote: you see each item priced separately, ready for leaseholders or Section 20 if needed.
- Access and permissions: scaffold or access equipment, local authority licences and resident notices handled for you.
- Work on site: carried out by experienced operatives using materials and methods suited to the building.
- Handover: joint inspection, completion photos and a record of works for the building file.

Frequently Asked Questions
How much do sash window repairs cost in Hampstead?
A single sash overhaul with new cords and draught-proofing is typically a few hundred pounds per window. Larger timber repairs or work across a whole block are priced per window after a survey. Repairing is usually far cheaper than replacing with like-for-like timber sashes.
Should I repair or replace my sash windows?
In most period buildings in Hampstead, repair is the better option. Original timber is often better quality than modern replacements, and most rot is local. We only recommend replacement where a sash is beyond economical repair.
Can I have double glazing in a conservation area?
Often yes, using slimline double glazed units in the existing or matching sashes, but it depends on the building and whether it is listed. We advise on what is likely to be acceptable before any work.
How do I stop my sash windows rattling and letting in draughts?
A full overhaul with draught-proofing usually solves it. New parting beads and staff beads with brush-pile seals close the gaps, and the sashes are rebalanced so they sit tight in the frame.
Can you repair sash windows across a whole mansion block?
Yes. We work with managing agents to survey every window, price each one separately for Section 20, and carry out the work alongside external decorations so scaffold is only needed once.
