Sash window repairs in Cardiff
Broken cords and stuck sashes are two of the most common problems with sash windows, and both can almost always be repaired. We get traditional timber windows running the way they were built to, without replacing them.
The sash window is a time-tested design and, when well maintained, should never need to be replaced. Most of the problems we see come down to a few worn or broken components, rather than a window that has had its day.

Broken sash cords
When a cord snaps, the top sash drops or the bottom sash won't stay open. We take off the staff bead, lift the sashes out, open the weight pockets and fit new cord to both sides, so the sash balances and stays where you put it. We always replace the cord on both sides to reduce the chance of the other side failing and to ensure that the sash is properly balanced. For normal sashes we use a 6mm diameter waxed cotton Ibex Marine cord.
Stuck or painted-shut sashes
Layers of paint glue the sash to the beads and frame. We cut through the paint, ease the sash free, clean the stiles and rebalance it so it slides smoothly.
Rattling and draughts
Worn parting beads leave gaps that let in cold air and let the sash rattle. We replace the staff and parting beads and can draught-proof the window at the same time.
Rot in sills and rails
Rot usually starts in the sill and the bottom rail of the lower sash, where water sits. We cut out the decayed wood and splice in new timber, then prime and seal it, rather than replacing the whole window. Where possible, we try to use locally sourced timber such as Douglas fir.
Cracked or broken glass
We reglaze with care and can match old glass where it matters, sourcing salvaged glass with the same aesthetics as the original.
Locks and fittings
We repair or replace catches, sash lifts and fasteners, and can fit restrictors.
If the damage runs through most of the window, a full restoration may be better value than separate repairs.
Why repair rather than replace
Repair preserves your original joinery and glazing, which matters most in period houses, listed buildings and conservation areas. It's also usually cheaper: see how much sash window repair costs.
Common questions
My sash window is stuck or painted shut. Can you free it?
Usually yes. Freeing and rebalancing a window is a common job.
My sash window rattles. Can that be fixed?
Yes. Rattling is usually worn parting beads or a loose fit, and draught proofing cures it.
Do you repair broken sash cords?
Yes. It's one of our most common repairs, and new cords make both sashes open and close properly again.
How much does a sash window repair cost?
It depends on the window and its condition, so we price from photos and confirm once we've seen it. Our cost guide gives typical prices.
