wall meets siding

[TGIN]

I am inclosing a covered porch . The house has double 4 V. siding . Is there anyone that makes a piece that is shaped like the siding to seal to the wall without having to cut the siding out where the wall meets the house to get a good fit .

Nothing like that made that I know of. I suggest cutting the siding with one of those multi-tool saws, it works real slick. Slide in a piece of J-Channel and build your wall to it. Nice fit, tight solid wall connection.

You can also lightly(2 nails) tack a 1x4 or whatever board you have laying around on top of the siding, and set the correct depth of your circular saw, and run it right along the board edge.

TGIN,
Let's say you find something like that, which I have never seen. If you have vinyl siding, how are you going to stop the air and bugs from coming in from behind the siding?

If you want a good seal, cut the siding.

If you don't care what it looks like, use great stuff expanding foam.

They don't make what you're asking about.

It will take less time and make for a better job if you take the siding down, build your porch enclosure then re-hang the siding using J channel where the siding butts the enclosure.

The next best alternative would be to mark your two plumb lines then unlock the bottom piece of siding from the starter strip. Use tin snips to cut the siding. You'll need yellow handle and green handle snips. Cut a few inches on one side of where the wall will be, then use the other snips to cut the other side. Green snips on the left cut, yellow on the right cut.

Be sure to cut the siding short enough to allow for expansion when the weather warms up.

I saw some on hgtv. It was made by a siding company, so there is a chance it will only fit their scale/siding measurements. Basically it looked like a 2x4 with a stepped edge. Kind of like a stair stringer.
