May not….

Look much but this is a single small glazing cill as I suspect when I fit the new sealed unit (collected this morning) that the existing may deteriorate/break as it’s been there in excess of 20 years.

Bit of research into ready mixed lime mortar and helibar (both required for shed repairs). I need to speak with S (Arteegeedee’s son) as to best place to get both as he is an expert in stonework/lime repair.

If he wasn’t so busy I’d get him to do the work!
