Installation of vinyl siding is not a rocket science. So if you got hit with a white hot beam of desire to do it and you believe you can do it, then no doubt, roll up your sleeves and lets start hitting nails.
Let us do something interesting of vinyl siding installation. I think we should go ahead and do that noble job of j channeling a window.
What do we need for that? Very simple hand tools: a vinyl siding shears, a hammer, and 1'' 1/2 or 2'' roofing nails, use 2'' if you have fanfold insulation on. You can use 1'' 1/2 nails if you have tyvek on and plywood walls.
We have tried different ways how to do it and by trial and error we finally got to the best one. The j channeled window looks nice and watertight, stays that way for many years.
Place the side j channel and mark it, then mark the bottom j channel. Do not forget to extend the side j channel above the top of the window frame, make it at least 1 inch above the top of the window.
That's it, we are all set, do the same way on all corners of the window. Remember the top has to be done the last. First goes in the bottom, then 2 side j channels and then the top.
