How to Mount & Flash Replacement Windows (No Nailing Fin)

Hi everyone, I have seen and read a bunch of different resources discussing how to flash and mount windows. I have yet to see any samples or images on how to flash and mount replacement windows that have no nailing fin. Does anyone have any insight or images on where the window should be aligned to with the framing/sheathing?

New windows come with nailing fins. The windows protrude about an inch outward and are followed by the nailing fin. These are easy to mount because the nailing fin is the back stop point. :confused:

jkirk, thanks for the reply!

I am going to take a few pics hopefully tomorrow. Currently the windows are leaking to I need to take them out and flash them and then reinstall them.

There is brick mold on the outside. Its wood and then has aluminum over it. The bottom piece of the aluminum skin actually tucks in to the bottom of the window.

I will take some pics and post back. The edge caulking sounds right just having a tough time visualizing the gaps etc.

There are things called "masonry clips" for installing windows where due to a brick veneer there is no way to use a nailing fin. The masonry clips are screwed or nailed to the jambs of the new window and bent over the 1 1/2" face of the jack studs and nailed in. The widow is then shimmed and foamed. Tight as a drum.

It sounds like the sheet rock would have to be removed to nail the clips to the jack studs.

Re: How to Mount & Flash Replacement Windows (No Nailing Fin)

I saw that this was posted two years ago and need advice on a similar job. I am looking to replace the wood windows in my late 60's brick ranch. The windows are wood frame, with aluminum slide tracks on the sides. My main question is how I go about replacing them. I am of the impression that I would remove the inside trim, remove the two sashes and then the aluminum tracks and whatever else is in there until I have just a plain wood frame. At this point I would measure the opening and get the window, standard size or custom fit, whichever it requires. Am I going about this the right way or is there something I am missing. I have replaced the single pane, aluminum frame windows in my basement but I had to frame in the area to cover the cinder block construction to have a frame to fasten the window to. I am familiar with the shimming, squaring, plumbing and insulating part, just have never tried replacing wood windows with the brick surround before. Any pointers you guys can give will be a big help. I was thinking to start on one of my smaller windows on the backside of the house so the neighbors don't see me when I lose my cool with the project.

What you are describing is the way "sash packs" work; they are ordered to fit the existing wood jamb/frame and add spring-loaded balances and a weatherstripping system. You can get 15 to 20 years service out of them typically before the seals break down and the glass clouds, and the spring balances malfunction.
