Cracked putty

[John]

Along the bottom of some of my wooden window frames the putty (brown stuff) has lifted and left a gap between the sealed units and the putty. Not too keen on replacing the putty as it won't match without a further job with the Sadolin. I guess the frames will need replacing soon (1988) but in the meantime I wondered if there is anything fairly fluid that I could encourage into the gap which will set and seal the gap. I thought of Silicone but I wouldn't be able to get it far enough into the cracks and the putty is a bit brittle for applying pressure with the nozzle.

Polyurethane wood glue ? - waterproof, foams to fill gaps & paintable

quicker just to reputty. If your frames need replacing soon, you must be doing something very wrong.

....actually they aren't too bad - but the double glazing gap is small and I want to change them to get the benefit of better insulation before I pop my clogs. I have one bay type which is a bit drafty due to poor construction - but I have applied all the usual fixes - then the foam strips rot away.

How big are the cracks/gaps? Captain Tolley's Creeping Crack Cure maybe what you are looking for but that is for fine cracks that will still allow capilary action to work rather than wide cracks or gaps.

no chance of that paying back its cost in your lifetime plus the next owners'.

Where is it leaking? Silicone lasts for better than cheapo foam. There are also different types of foam, some last many years, some just about manage 1 yr.
