Window replacement frustration

I have watched all the videos I can find on Youtube but still have some questions.

I have one window to replace in a bathroom that I have completely remodeled. After completing the bathroom I thought I'd just hire a window company to do it. However, I discovered that no one will replace just one window or if they will, the price is outrageous. So I figured I would just do it myself. My frustration has been in getting assistance with ordering the window. Everywhere I go, the staff are basically useless and can do nothing beyond entering numbers into their software. When I ask questions about particular measurements they don't even know what the measurements are for.

My house is from the 50's, in Edmonton, and the current window looks like a 40(?) year old aluminum pocket type built into a frame a few inches inside the rough opening. The exterior trim is capped with aluminum (which I want gone). I intend to remove everything down to the original rough opening. The interior trim is all gone now so I can easily measure the width and height of the rough opening.

1. Is the requested "jamb width" measured from the interior drywall to the exterior stucco surface? Or is it from the drywall to the sheathing surface under the stucco?

2. I am having trouble planning for the stucco. I envision the brickmold attached to the window slipping nicely into the space between the stucco but I'm not sure how to make this happen. How do I know how much of the stucco to cut back to allow the brickmold to fit? The stucco does not need to be cut to remove the old window, only to expose enough rough opening 2x4 for mounting and to accommodate the brickmold. If I order a 2 inch brickmold does that mean that I should cut the stucco back about 2 inches from the rough opening?

Every window I've ordered, after choosing a particular type of window, has only required width and height dimensions (in that order, width is always the first number). Now, if you're doing a casement window (crank out style), you would then also need the jamb depth, or the distance from sheetrock surface to at least the outside of the rough opening (no stucco or finished surface).

I would say that jamb width would refer to opening width, but it is an unfamiliar term to me. If you've chosen a brand/type of window, then go to the manufacturer's website, they should tell you exactly how the opening needs to be measured for that particular window. If you can't find it on the site, then I'd contact customer service and get clarification from them. With this information in hand, you can then go to a local supplier to order the window, that is, if you can't order directly from the manufacturer, which could cut out middleman mark-up and middleman idiocy.

Ok so first off I find it ridiculous that the window supplier would not be way more helpful then they are and even come out and measure for you if need be.If you are dealing with a big box store then what your describe would not surprise me but if it is a local lumber store they should have more experienced people.

I don't completely envision the exterior of this exiting window so a picture will help me out here please.

Sadly, it was 3 different big box stores that gave me the run around. I figured at least one would know what they are doing. Guess not. ;)

Anyway here is the outside:

Here is the inside, The drywall edges are on the edges of the rough opening:

Ok You have a very wide exterior trim on three sides and even the bottom is pretty decent.So the stucco should really be a non issue. I would think you will actually have to fill in around the exterior of the new window brick moulds. So I would figure out a "box size" from the existing RO. Measure the RO and deduct 3/4"and that will be your frame size and leave you 3/8" of space to insulate all the way around.You can then ask for either 1-1/2" or 2" reno BM.

If you do not want to fill in around the BM to match up to the stucco you could also order nail fin windows instead and then build your own BM trim work outside using PVC trim or whatever you want.

For the depth of the frame for either case you would measure from face of exterior sheeting to face of drywall. Now in most cases with older homes this will be a non standard depth because the exterior will be 3/4" wood instead of 1/2" plywood and if the home is really old the stud widths may be different then 3-1/2" as well. So you can either custom order the depth to what you want or order a standard depth window (in your case likely 4-1/2") and make it work.

I personally recommend you look at getting "AllWeather " windows. You will have a dealer up in Edmonton for sure.

Thanks for the reply Shannon. I'll go check out All Weather tomorrow.

I guess my concern about the stucco was because if I toss out that frame that the aluminum window is in then the rough opening gets much closer to the edge of the stucco. But I guess I can always just place the window when I get it and grind off any stucco that needs to go to get a good fit.

If that was normal 1-1/2 wood brick mold I would normally just measure the outside of the existing BM and deduct 1/8". I would then order my new window with 2" reno BM to those dimensions knowing it would fit through the RO, but in your case that BM is wider then standard 1-1/2" BM so the window would not fit into the RO.

AllWeathers 2" reno BM projects 1-3/4" wider then the jamb dimensions and their 1-1/2" projects 1-1/4 more then the jambs.

BTW if you order BM windows instead of the nail fin I would recommend BM on all 4 sides instead of a sill on the bottom. I think its a better ,more secure install that way.

A third option I guess is also to leave the old frame in place, remove the aluminum insert and order the new window to fit inside of the old frame with BM sitting on the metal outside. Your depth of frame would then be measured from face of old BM (metal) to face of drywall inside room.

That's great info regarding the BM relationship to the jamb dimensions. Thanks.

Didn't get to the window store today but I did manage to get a better view of what's under the capping. It is a 2 1/2" wood BM plus a 1/2" stop. I determined that there is a distance of 1 1/2" from the rough opening to the outside of the BM.

So assuming a 3/8" insulation gap and a 1 3/4" BM projection, should leave a 1/8" gap from the BM to the stucco. In theory, and assuming my calculations are correct?? :?

A 1/8" gap should be easy to caulk at least for the top 3 sides. I'll have to investigate more on the sill side.

That is a normal BM under that then. It looked so wide in picture I thought it was something different.
You should be able to do what I do. Measure the outside dimensions of BM and sill , deduct 1/8” from those two dimensions and order your window with 2” Reno Bm all the way around.

OK, so thanks to your help I was able to get a window ordered and it arrived today. It is an All Weather Windows Horizon 7100 Slider. However, the installation instructions are woefully inadequate. I can get it into the hole, caulk it, shim it, etc. What I don't know is where exactly to locate the installation screws. It does not screw through the front of the brickmould but screws through the side jambs. There are no holes marked. I'm assuming I can put 3 or 4 screws into the 40" side jambs but what about the head jamb? Looking online, I see some brands call for screws in the head jamb and some that don't. Any ideas for these screw locations?

Generally you could place 1-2 screws in the head jamb depending on the width. If its under 36" then one near the middle will do if its wider place screws about every 16" or so.Be careful not to pull the frame out of shape if you are screwing in locations without shims.

Well I got the window in today. Just a quick question about caulking around the brickmold where it meets the stucco. I plan to caulk around the top and sides but what about the bottom? Should I leave it open? Just leave open gaps? Seal it up? Thanks.

I have nothing to add as far as your question, but I am in the exact same predicament as you...single bathroom window to replace.
I contacted about 15 companies, went to the big box stores and even desperately sought out help on Craigslist.
Luckily, we're in good hands on this forum.

I hear you. The window was the very last thing I did on my bathroom remodel. I demo'd the original plaster right down to the studs and sub-floor, replaced the bathtub, vanity, and toilet, put in new drywall, learned to do porcelain tile with a heated floor, put in new lighting, painted, and installed a new door. Out of all that, the window was by far the most difficult job to find info on and to learn to do correctly. After finally finding a lumber yard that could help me measure and order the window, even they wouldn't return my call when I asked for installation advice. I even tried calling the window manufacturer and was told they are just people working in an office and that I should call a contractor to find how to install them. Just for the basic install questions like I asked above. Unbelievable. What is it with the window business?

Thankfully, I got most of my answers answered here and on Shannon's videos. My final task is to put on the interior trim today. My window jambs ended up to be slightly narrower than they should have been due to the house's thick old-school sheathing boards) so I've got be a little creative with the trim. But I'm pretty sure I can handle it.

Thanks again Shannon for all your help.
