Topic tags/keywords: exterior window sill question

Hi everyone,

I’ve been using this site for a while now to help me out on several projects and now I’m posting for the first time.
My wife and I recently bought a house (built 1920) and are having many of the exterior window sills replaced due to dry rot. My wife all out refused to let me do the sills saying id take too long and hired a crew that her friend said did an amazing job at her home. Well today the crew started on windows and took my lunch break to come see how they were doing.

First thing I noticed was that the trim and sills were not angled away from the glass. I’ve never seen one level, all I could imagine is standing water or water somehow making its way in? Correct me if I’m wrong here? I asked the main builder why he chose not angle and he said that he flashed/taped under it. Will that work well enough on its own?

Second, as I went back to work I was looking at my pic and I’m pretty sure he used red oak trim. I had always thought red oak was for interiors only?

Thanks, and sorry for venting-I just want the job done

I don’t see much of an issue with using oak, but I do have a problem with the sill laying flat regardless of what was done underneath. That is just a bad idea and a poor window construction technique.
