I'm by no means an expert, but I think water is going to soak up through the concrete sill into the bottom of the timber and rot it out from beneath. As its redwood/pine it'll rot much quicker than the previous sill which was probably oak. The black sealent around the edges is going to do nothing as the concrete is porous and water will just rise through the concrete directly into the timber. That said it is a fix and you'll probably get 5-10 years out of it before the same happens again. If it was me I'd probably have laid a sheet of DPM underneath the wooden sill.
Thanks for your comment. Plastic membrane would be a good idea for the next one I fit. It’s much better than it was and saved money doing it myself. I never see myself as an expert but I do like to have a go at repairing 👍
Couple of things i would add, firstly don't use soft wood for a sill unless you are broke. Try and get a layer of dpm under sill, plug screw holes with matching wood plugs. I think Rich is an amateur diy'er, nothing wrong with that but do some research first.
Just purchased a weather bar/door step for my outhouse, pretty much the same as yours. Thanks for the video, I will doing exactly the same job.👍
Well done
That should sort it out
Thanks for watching

I agree. Maybe using a cement primer and paint will also work.
Thanks Michael. Yes another home improvement done 👍😊
Thanks for this the this is almost identical to the issue I have.
Hope it helps and you manage to replace yours without too much fuss Anthony
Great video, thanks

Thanks for the advice John.
I am most definitely an amateur but am willing to learn.
Hi mate where did you get your replacement sill?
Hi, I got a local timber merchant to cut it for me
Looks like a 2 by 4
Hardwood all the way. That’ll be rotten in 3 years.
Thanks for your comment Nick
2 years in no problems yet.
Just put another coat of varnish on 👍😊
