Your doors look great. Good job.
When weather permits, I'd recommend:
1) Treat the siding with Jomax and bleach, as per Jomax directions. A gal
lon of Jomax should be enough to clean your whole house, as well, if need b
e. If you're up to the task, scrub the siding, also.
1.a.) After the cleaning is done, you might spray all the siding with strai
ght bleach. If there is any deep mold or mildew on the siding, you might w
ant to treat it with concentrated bleach, without rising it off. Do the s
praying on a good dry day, so that the bleach better penetrates into the cr
evices. Any mold or mildew (spores) may be deeper, than just on the wood's
2) Seems you may have to trim the bottoms, up, at least 10". Use a sharp t
ool or screw driver to stab the siding, to see where it is weak, rotted, de
cayed, etc. Don't be afraid to stab hard. Draw your trim line above the d
3) Attach a board below the trim/cut line, so that your circular saw rests
on the board, blade even with the cut line and beveled about 30 degrees.
4) Prime the cut, well, when you prime the rest of the siding. Once primed
, mark the siding (where you made the cut) as to where your wall's studs ar
e (re: #6 below).
5) For your application, wooden drip edges, as I have, may not be the best
application. For a different application, I bought some 10' angled flashin
g, 4" on each leg, from Lowes.... like this http://www.lowes.com/pd_366940-
18591-A3X4X7_4294736325__ , but 10' lengths. I can't find the 10' stuff,
on Lowes link. This sort of drip edge may be better for your shed and bet
ter for installing, than wooden drip edging. Once installed, bend it to an
5.a.) Whether you make your own drip edge or use metal flashing, caulk its
installation, along the upper siding.
6) Once the drip edge is installed, attach the bottom edge of the upper sid
ing to the studs, if need be. That bottom edge might need attaching right
near the cut line, if the next higher attachment is too high.
7) Cut and prime for your replacement lower siding. Cut both top and botto
m edges at 30 degrees. Prime the back side, also.
8) Put a flashing along the lower edge of the building, before installing t
he replacement siding.
The worst part of that job will be cutting the bad siding off. Kneeling an
d cutting with a circular saw, that way, is not fun.... at least for us old
