I put glass, multi pane french doors on them. 

Off the top of my head, I'd say replacing them with new vinyls is the way to go, especially when you mention storms being involved, so these are older, single-pane windows I'm guessing.

There are hundreds of strains of mold, and several strains are considered toxic, and not always easily visible to the eye.These types of projects can be tedious and costly due to having to replace a lot of building materials and the remediation work involved. 

We always used new paint, but after replacing the entire piston assembly once (about $300), we began straining it anyway.

Our business model supports having a healthy blend of both: 1) Properties we own - allowing us to create value through equity and 2) properties that generate passive income for us would the financial strains of ownership.We just acquired a SFH 2 weeks ago.  

This is why you stick with cheap single pane aluminum windows.cheap and easy repairs.Originally posted by @Nathan G.

I've had a strained relationship with this tenant since buying the building, and she is using what's left of her security deposit as part of her rent for the last month.  

If you attack the frontage windows to get dual pane, use the Anderson wood frames and not the vinyl plastic stuff - - just ruins the architecture. 

A demonstration panel I saw at a store, allowing customers to tap on four samples with a small mallet, was marginally informative.

They were original single pane aluminium so I didn't wait.
