Concrete Door Sill and Installing new Composite Door

Postby DIY-genie » Wed Apr 08, 2020 4:41 pm


New to here so hopefully I'm posting this in the right place.

I'm looking to replace an existing wooden front door and frame with a new composite door set.

The question I have is the existing door has a concrete sill with a metal strip inset as per the attached picture. I suspect it's going to be hard work to remove it so I'm looking for opinions on my options, which I see as:-

1. Leave the existing sill in place, angle grind the metal strip down to the level of the concrete and then fit a composite door set with a shallow threshold on top of the existing sill.


2. Removed the existing sill and replace with a sill supplied with the door set.

Any advice or previous experiences welcome as I'm struggling to decide which is the best option at the moment.

Hi DIY-genie,
Much better to remove the old cill - borrow/hire a small breaker.
