    We got Passive Sills from https://passivesills.com/ 5 years ago when we built our house.

    They look absolutely dreadful now - they've gone moldy/stained and just look dirty. I'm afraid to scrub them as the coating is quite delicate. The front window is very large, and the sill is actually warped due to an issue during installation (long story) so one end of the sill bends downwards - it looks dreadful.

    Anyway, was wondering if this type of aluminum capping could be a good solution for us? I did think of painting them but this could be a more durable solution.

    Would you recommend, and can you comment on this supplier?

    Have you tried a treatment (something like 'Mosgo') to treat the mouldy discolouration. What you are seeing may well be just organic growth which is easily treated. This won't help any warping though!

    Ring the cill suppiler, they’ll reel you what to use.


    the powder coated cills are the job, but you’d have to redo the render at get them to work - note the upstand at the edge of pc cill
