siding install question

rbyham

I am ready to install siding on a new addition. the addition created two inside corners where the side walls come away from the existing house. As I side the new room with matching siding how do i create the inside corners? I am thinking some sort of 1x1 batten in the corner to let each side butt up against flat surface. Is that the way to go and if so what materiel should be used? Thanks.

You don’t mention what type of siding but a 2x2 (1 ½” x 1 ½”) is pretty common. You can go smaller but nothing under 1”.

If you’ll be caulking the face of the siding the corner should protrude no less than a ¼” past the butt of the siding giving you enough room for a bead of caulk.

Of course if this is vinyl siding they make an accessory for the inside corners.

There are vinyl or vinyl composites that eliminate water issues and possibly painting. For vinyl siding, there are premade corners available from most manufacturers.

Follow-on question: Is it better on an outside corner to take the siding up to the corner and then put the vertical trim boards overtop? Or to install the trimp boards first, and then but the siding up to the trim boards? On my house - built in 2000, they seemed to use a bit of both techniques -- mostly trim, then butt siding, but some of placing the trim atop the siding.

Just thinking about it, the trim, then butt siding approach seems like a simpler solution so long as there is a nailer in the framing for the siding.

Thanks quickfish... My siding is 7/16 x 12" some sort of wood product. Sorry I did not catch the name. It does have a faux wood grain exterior if that helps. Comes already primed but will need to be painted. I was thinking something 2x with me needing to cut the original wall siding back in order to insert the 2x2. Correct? Any recommendations on material to use? I have a 2x2 piece of pine in my hand the other day but that will need primed and painted too. Just wondering if there are any options. My soffit trim material was some sort of Masonite product that looks like it might hold up better than something soft like pine. I guess I am mildly surprised that some standard trim piece is not the way to go - not arguing just trying to think it through... Thanks!

A 2x2 is pretty standard. I use Cedar but you could also use treated pine or fir a composite material or pvc.
