Sash window repair
Windows that stick, rattle, won’t stay open or let the cold in can almost always be repaired. Shaun has been putting box sash windows right for over 40 years.
What goes wrong, and how Shaun fixes it
Old box sash windows were built to be maintained. Most faults have a straightforward, traditional repair, so the originals can stay.
Sticking or painted shut
Years of paint build-up and swollen timber jam the sashes. Shaun frees them, eases the edges and beads, and gets them sliding again.
Broken sash cords
When a cord snaps, the sash drops or won’t stay open. The sashes come out, new cords go in, and the weights are rehung and balanced.
Rattles and draughts
Worn beads and gaps let sashes rattle in the wind. Beads are adjusted or replaced, and brush-seal draught proofing can be fitted at the same time.
Draught proofing →Rot in sills and bottom rails
Rotten timber is cut out and new timber spliced in, then primed and painted, rather than replacing the whole window.
Loose joints and glazing bars
Joints are re-glued and pinned, and broken glazing bars are remade to match the originals.
Beyond repair?
If a sash really is past saving, Shaun makes a new one in the workshop to match the rest.

Why repairing is usually the better choice
Most old sash windows don’t need replacing, just proper care. The timber in older windows is often better quality than much of what is available today, and a well-repaired sash window can keep going for decades.
Repairing usually costs far less than new windows, keeps the character of the house, and matters for listed buildings and conservation areas, where replacing original windows can need consent.
Shaun will give you an honest opinion. If a window is past saving, he’ll say so, and he can make a new sash or window to match.
Sash window repair questions
How much does sash window repair cost?
It depends on the size and condition of the windows and what they need. Shaun will visit, look at the windows and give you a clear, no-obligation price.
Can you repair just one window?
Yes. Whether it’s one sticking sash or a whole house of windows, Shaun is happy to quote.
Do you replace broken sash cords?
Yes. Re-cording is one of the most common repairs. The sashes are taken out, new cords fitted and the weights rehung so the window balances properly.
Do you work on listed and period homes?
Yes. Shaun has over 40 years’ experience with period and listed properties and repairs like-for-like wherever possible.
