Of course, sash windows are notoriously prone to rotten timber – particularly in antique abodes where a conduit for water ingress has occurred by paint failing over the years. The good news is that rot does not always mean new windows. In many instances, a little bit of expertise can repair the frame and preserve your home’s fundamental character.

Where rotted timber can normally be salvaged
If the rot is localised (e.g. to a section of bottom rail, sill or just one corner) it can frequently be cut away and replaced with fresh wood in a technique often referred to as splicing-in. Which is great as long as the surrounding wood isn’t completely rotted and if your window is still structurally straight. With a repair, the area is fixed and then treated with primer to ensure that you do not have this issue returning.
More suitable for repair
Repairs can border on a patchwork that will soon give way if the rot is extensive, deep or involves almost all of one or more rails, stiles and even its box frame. You might also have to consider replacement if the window was repaired inappropriately previously, is excessively warped or there is still water intrusion happening that can’t be resolved (i.e., flashing fails as well as leaks, very high condensation issues).
If it is a fine line to call either based on the condition of several spots, then it may be time for an evaluation and some deliberation when breaking down repair versus replacement.
Whatever path you decide on, the cure for hardwood sash windows is always prevention: good preparation work, right line of paints and rectifying water entry will keep these timber sash windows looking wonderful forever.
