Worth Replacing Existing Windows?
 
My current windows are aluminum framed single pane, and pretty old, but there are two sets. The inner one has the aluminum frame set inside the casing around the opening. The outer one has a flange that appears to be fastened to the outside of the casing.

Is it worth replacing these with double-pane vinyl windows?

Without knowing more about the home and your motivation for replacement, it is impossible to say.

That window is certainly not efficient and by the time you retrofit it and the storm to be air tight, you are going to have a bunch of money in a very outdated and inefficient product.

Combine that with the fact that you are going to repair some paint, caulking, and wood rot repair (most likely) the logic behind replacement becomes even more sound.

Do those bricks tilt downward - away from the window?

If they're flat - or only slightly angled - that would explain why there's water flowing into the window area and not away from the window area. Even if you just swap out for a new window you'll eventually have the same problem unless you repair this brick issue. And if it's in the window and the sill then it's down the wall, too.

My approach to things like this is to take out all the water damaged area, identify all the reasons for the damage, and repair things so recurring damage is adverted forever.

If the brick sills are sloped in, that is wrong and needs to be fixed ASAP.

The caulk is mighty! But do not rely on the power of the caulk to save you of all ails!

The brick on the sill does slope away slightly.

Snav, what would you do to "repair the brick issue"? Is it really that big a deal?

Next question is, what sort of vinyl frame do I go with? Block frame, Z-bar, J-channel? Whichever I go with is going to need some exterior trim/casing; I guess the real question is how much.

Insert frame with wrapping will work fine if done properly.

Is that block frame?

What kind of "wrapping" is best?

Insert is what is referred to as a block frame.

Wrapping is what is considered trim wrapping (i.e. aluminum capping).

Thanks. So is aluminum better than vinyl/extruded poly? And where does one get such products around here?

Block frame for sure in that opening. Aluminum or Vinyl is personal preference. You can order windows at most home improvement stores, Home Depot and Lowes for sure.

If a sill doesn't have enough of a tilt to it the water will puddle towards the window - other issues that you have like the algae growth occurs as well.

It doesn't take much to tilt the bricks downward: a careful removal of the existing sill bricks - removing the entire or partial row beneath and then setting the old brings in new mortar with a new angle.

When I took out our kitchen window I didn't sill the opening with bricks - instead - I built the new framing for the window with an angled base on the sill, no ledge. This lets all water wash off and will give us no problems in the future like cracked mortar and other things.
