Repair or replace window sill
Decayed or rotten wood sills
areas of decay which do not affect the structural integrity of
the sash window can be cut back to sound wood and filled with
a 2 part exterior resin filler. Larger sections of rotten timber
will probably neccessitate the removal of the sill and replaced.
All new wood sill are properly seasoned and painted with a presevative.
b) Sills: Decayed sections should be cut back to sound wood and
new pieces of timber should be glued and screwed in place using
external quality wood glue and non-ferrous (eg brass or stainless
If the ends of the sill have decayed, it will probably be necessary
to replace the whole sill. This can be difficult as the best join
with the box frame is achieved if the new sill is inserted from
underneath. To allow this, either internal plaster and brickwork
or the external (stone) sill may need to be removed. If neither
of these is possible (if, for example, there are elaborate architraves
or shutters) it may be better to cut off the bottom of the inner
lining, ensuring that the sill is glued and screwed to the pulley
and outer linings. In extremes, it may be necessary to insert
the sill in two pieces, halved in the middle with an overlapping
joint, glued and screwed.
