Small rot can be treated with specialized liquid wood hardeners and epoxy resins. Nevertheless, if the decay is comprehensive, a "splice repair" is carried out.

5. Re-balancing and Re-hanging
When the sashes are repaired and painted, they need to be re-installed. New, top quality waxed cotton cords are fitted. Because repair work or brand-new glass can change the weight of the sash, the lead or iron weights inside the frames are changed (often by including little lead "make-weights") to make sure the window stays completely well balanced and remains open at any height.
