Most of those questions are aesthetic and largely personal. You may not be able to match the muntin size or style exactly, but the naked eye is easily fooled. Whatever you decide to go with, make it something that you will happily put in the rest of the home when you are done. If you haven't tried Ultra Windows in Houston, I would give Randy a holler there.

Yeah. I have the partial double drip cap right now on my windows (only over the window, and then over the whole trim board above the window), and would like to get the full width drip caps for more security. Been watching install videos from Marvin about good practices, and seems like my contractor is on the right page. One issues that arises that I would love an opinion on: my house does not have Tyvek or other wraps close to the windows. Original windows were set and nailed in, and then the cedar wrap put around, and THEN Jumbo D paper installed for the stucco butting up to the trim. When they take the cedar off and the window out, I will have a bare opening with 6" around the perimeter of it with no wrap, or wrap into the opening. Is it worth it, and can they do it in a way to not disturb the stucco, to "wrap" the window opening? Of course they will need to make sure they layer it in a way to ensure proper drainage plane. Is this something I should advocate to be done as well?

IGUs (Insulated glass units) are replaced as a unit and can't be field repaired on one side. Can the window sash be easily removed from the window? If so take it to a glass shop and get an estimate on the repair. If the frame comes off easily then one can take just the IGU to a shop and have it replaced, then reinstall in the frame. I can see three options: 1) have the tree guy coordinate the reapir with your tenant, 2) Call a local glass company, have them go to the property amd do the repair and deduct it from the tree guy's invoice. 3) Ask your tenant to handle the repair and compensate him/her accordingly. You don't say the size of the window and you're picture doesn't hint at the level of effort to remove and replace the IGU on this particular window, so it's difficult to guestimate the level of effort to fix it.

John, Some pictures will help out us by letting us see what you see. As a general rule, if you are setting a pocket/insert style window...you will have to cut through or removing the flange if we are talking about a vinyl window.
