I’m in the process of applying Hardi Plank clap board siding over a bay window addition. I was planning on using 5/4 trim at the 2 135 degree outside corners but the location of the windows relative to the corner requires the corner trim to butt against the window trim. The overall effect is a bit over powering. So I was wondering if I could drop the corner trim and butt the clap boards together. One idea was to use a piece of flashing over each course that’s bent around the corner to cap the butt joint. Another idea might be to use custom molding to cap the butt joint. Any ideas …

There was a thread about mitered corners on hardie some time back. I think it may have been Blue or Mad Dog that hd done it.
*Rick,If I read you right, it seems like instead of butting the two types of trim against each other, you will be putting little short pieces of hardieplank there instead, and in this area omitting the regular 5/4 corners.I have not mitered the edges of hardie siding to match. It may work. It's no problem with cedar siding. Another option would be to use a thinner piece of corner trim just in this area or, we had a guy post a while ago about running trim over the hardie-type siding. (I don't know if he did it).The metal caps you mentioned may be okay, I'd probably call the siding manufacturer and see if they have alternatives or at least how they'd recommend attaching the caps, but I've never been crazy about that look on clapboard in the first place. Obviously, the most important thing is getting a good seal on the corners, maybe if you mitered them with a saw and sealed with recommended adhesive?Is this window set real prominently displayed? How wide is your regular trim? Is it just one small area or are there more to do?Good luck, MD
