Replacing window and doors, installing siding; I have a plan, am I missing anything?

[confusedcarp]

I want to replace a window and install new doors and siding on my detached workshop. After much research, I've come up with a step by step plan. However, since I've never done anything like this, I'm hoping someone can please take a quick look at my plan and let me know if there's anything I've missed or if the order needs to be tweaked.

1. Prep exterior - remove trim, scrape flaking paint
2. Remove front door and jam
3. Remove window
4. Reposition window studs and cut opening to size replacement window
5. Install new patio door studs and cut opening to size
6. Dry fit replacement window and doors and adjust as necessary
7. Patch vent holes with plywood
8. Seal bottom of exterior sheathing
9. Install drip flashing along bottom of sheathing (needed?)
10. Install exterior house wrap
11. Tape seams
12. Install tape flashing around window and door openings
13. Install window
14. Install doors
15. Install Drip flashing above doors and windows, tape house wrap down over flashing
16. Paint and install corner, window, and door trim
17. Install soffit, fascia, and roof drip edge (this is a retrofit, doesn't exist yet, might do before or after panel siding depending)
18. Install panel siding
19. Cover panel seam on gable ends with painted trim
20. Caulk nail holes and seams
21. Paint
22. Install gutters

In particular, I'm a little unsure of the siding/trim steps. I'll be installing LP SmartSide panel siding and I wonder if I can (or should) trim it after it's installed rather than before. I have seen installation videos showing either way. It'd be easier to do it afterwards, but easy doesn't equal right. Any thoughts?

If your doing the siding and windows/doors get new construction windows with the J channel built right in. Not sure if you can use LP smart siding with that type of window but they are superior in shedding water.

I own and can use a siding brake but still prefer to use new construction windows. They do make some prety good flexible and liquid flashing now but they are very pricey.

#1 Is having the financial means and time to do the project! Remember; “Time is Money”!

#2 Is having the ALL materials on-hand BEFORE you start- there is a severe shortage of just about everything.

Now your list can start…


And my own point- LP’s siding is starting to have some issues. It’s starting to sound like the same thing that happened previously on their “lp knot” siding. You may want to reconsider your siding choice.

Thank you for your tip! An integrated J channel sounds like it'd be very convenient. Unfortunately I'm limited to one particular window only (the joys of living in a small market). It's new but no j-channel. I think this will be okay because I'm using panel siding which doesn't require j-channel.

All good things to consider, thank you!

Fortunately, #1 is covered on both counts. I've been using a spreadsheet to budget material costs based on what I can source locally. I anticipate it's going to take a lot longer and more money than I'm initially budgeting but such is the way of projects especially when one is starting with limited knowledge

#2 is definitely a good point. There are shortages everywhere! I planned around what's in stock at my local stores and so far have sourced (and ordered) most everything I need. I still need trim, cauk, nails, and soffit. I'll be sure I have (or can get) them before I start.

Whoops! Too late. The siding is on its way already. Here's hoping there isn't a problem
