Crumbling Window Sills

    I have 2 concrete window sills that will need replacing in the near future.
    The metal in one of them is showing and it's looking very corroded and the other one is crumbling at one corner.
    Just wondering what would it cost to replace both of them. TIA

    If the rest of the concrete is sound it is possible to repair concrete sills where concrete has spalled around rusting rebar, although it is labour intensive and requires scrupulous preparation to be successful, using a proprietary repair mix like:

    The alternative is complete replacement- hack off plaster to internal reveals/ jambs, remove window and windowboard. Break out ex. cill. Fit new sill with wrap around DPC, re-fit window and board, replaster/ make good. Depending on window size I'd imagine you could be be looking at up to €200 per window for such a job, maybe more?

    Probably will need to replace the worst of them. Just needed an idea of the price.
    Might be able to repair the other one as its just the corner.
