I have a house that had stone built on the outside of the blocks which has now been removed
The window sills are extra wide to suit the stone work which now need to be replaced, the double glazing windows are sitting flush with the outer block
The window sills have to move back to the correct place along with the windows as the house is going to be plastered and no more stone
The DPM is in the cavity where in should be so its just the job of the sills being replaced and new windows fitted
I was wondering is the sill work something that could be done by myself with the correct advice or should I leave it to a proffesional?
