KLIS JOINERY & CARPENTRY LTD
LONDON TIMBER SPECIALISTS
From a snapped cord to timber rot, we repair timber windows of every type across London, often for a fraction of the cost of replacement.
Whether it’s a sash, casement, or bay window, we assess the real condition of the timber and hardware, then carry out the repair that actually solves the problem, not a quick fix that fails again in a year.
Call us if you’re experiencing:
Many timber windows don’t need replacing. We assess each window honestly and recommend repair whenever it’s the more practical, cost-effective option, saving you from unnecessary expense.
Decayed sections are cut back to sound timber and spliced with matching new sections, not just filled and painted over. This keeps the repair structurally sound and true to the original joinery.
Sash, casement, and bay windows all have different mechanisms and failure points. We work confidently across all of them, so whatever style your property has, we know how to fix it properly.

Minor repairs such as a broken sash cord or sticking window typically start from £180 per window. More involved work like re-glazing or minor timber rot runs higher, and full timber restoration on badly decayed sections costs more again. We confirm exact pricing after a free assessment.
In most cases, rotten sections can be cut out and spliced with new matching timber, keeping the rest of the original window intact. Full replacement is usually only necessary when decay has spread extensively through the frame.
