There are companies that do ne windows to look like old ones . Those are probably not energy efficient at all so nice new ones that look the same but are douple paned would be IMO the right choice . They will not be cheap but you will save a ton on heating and cooling when done.Kolbe is a compant that does this maybe start there .BTW you will get also a company that is going to try to save those since yes there are places that will take them.

I should add that the window replacement company said these will be destroyed when they’re removed, which also kind of bums me out, but more for sentimental reasons. Is there any resale value in old windows of this sort?

Rehab them. They’ve lasted a hundred years. Modern replacements will last thirty. Look at indow interior storms if needed.

Undoubtably they will be.

No, once removed they will be worth nothing realistically.

Get a price rehab them and then make a decision. What area of the country? How heating or ac dominate is your climate? They are steel (non thermally broken), single paned, push-out french casement windows that will only get so tight and or energy efficient even with a full rehab. Really comes down to your climate and the dollars you are willing to spend. Personally were it me, I would replace them, although not with Andersen's but a steel look aluminum window like ArcadiaT225's.

@millworkman thanks for the feedback. Location is northeast (tri-state area). Our energy costs are through the roof, no pun intended. I'm sure a huge part of that is these windows, though there are many other inefficiencies here.

I stated Andersen, but I really need to clarify on what she chose replace these with. She has good taste, but what I saw didn't have the character of these old ones. Of course "character" has its trade offs :-)

Check out this blog that deals with everything about old houses--this page is for windows:

Character typically comes at a price point for sure. Northeast I would definitely highly consider replacing.

Rehabbed or not, as a buyer, I would probably think those windows are a heat/cooling sinkhole and that I would have to replace down the road. Your choice of course. I had a 1927 architecturally spectacular home before. Limestone exterior, beautiful crown plaster moldings, slate roof. My windows were wood. I didn't view original windows as a plus.

People in a nearby historic district voted to dissolve their district because replacing the casement windows there would cost a fortune

We had an old house, 1911, with beautiful original wood windows. For those we were able to remove the single paned glass and router in a channel to put in double paned low e units. Because we kept the framing, the appearance didn’t change. That technique won’t work with your metal windows though. I’d replace them with some architecturally worthy windows. You can also try to salvage and repurpose an old window as a mirror to hang in the interior of your house.

You will never have this much clear glass with a replacement window. These were built into the masonry as the house was constructed so the frame is hidden.

An energy audit that included thermal infrared images would show where the main heat leaks are. After you see the images where the problems will leap out at you, it will be easier to direct your money at fixing the main problems. The windows or lack of insulation in the attic could be the worst problems.

No matter what you do, it's an expensive fix, but PLEASE DO NOT REPLACE THESE WINDOWS WITH Anderson VINYL FRAME WINDOWS! It will destroy the appearance and value of your home. With some research, you'll find replacement Tudor windows.

I would replace them, more so the colder the temps.

Given your location, not sure restoration, event with some sort of interior storm window (not even sure how that would work here) is worth consideration. The idea that replacement windows only last 30 years is also an unproven assertion.

WOW no insult meant but ever tried to fix a ‘new’ window when a part breaks? Most of the time they end up in the trash. Countless questions on here from people with name brand windows a few years out of warranty and all they need is a crank or weatherstripping and it’s unavailable. Glass is replaceable until the gasket dries up and can’t be replaced. There is a place for replacement windows but they simply can’t be repaired when they inevitably fail. This window can be fixed for another century and work as well as it was designed to do (which I realize is nothing like a new window)

Hopes makes steel replacement windows but they are expensive.

My house was originally designed with steel windows. It never had them, it had mostly plate glass held in by wood stops, and most of them had been replaced by vinyl replacement windows by the time I bought. I looked at the steel windows but they were out of budget.

This is not my house, but it is by the same architect, built around the same time, early 1960s.

This is what I had when I moved in, some sort of vinyl replacement window:

As you can see is nothing like what the architect had originally specified.

And this is what the windows were replaced with. The are not as minimal as the steel, especially from the outside. But I chose the narrowest muntin. This is a wood clad window with a greenish black exterior and the casement portion of the inside has been painted black to look more like steel. (Not the entire unit, just the narrow part of the casement you can see inside and the muntins are black). They don't look identical to steel, but they evoke the idea.

Note that these are not replacement windows, we replaced the entire window in the masonry opening.

One is a bit different as it's a French casement in case we need to get something upstairs that won't go up the steps. We also had to fir out a bit and insulate. The house was mostly masonry construction with no insulation whatsoever. It wasn't just the windows that were an energy problem.

The point is, that if you buy the right window, there may be something between the original and something that ruins the esthetics of your house, closer to the generic replacement end of the cost scale than full on restoration.

@HALLETT & Co.

No disrespect taken. You are right on the engineered obsolescence aspects of ALL American commercialized products. Have you tried to fix a washing machine or a toaster...they are more expensive to fix than throwaway. Drives me crazy.

There are a few good suppliers out there that stock consumables for window companies as they phase them out. I have fixed some old windows with the right parts.

If the window weren't in the NE and the application of a storm window mostly infeasible, I would also recommend to keep them. We certainly appreciate the sustainability of some products. Not sure a steel casement in the NE fits that description here. Maybe with a removable interior storm...but how much money do you have tied up in that largely unusable combo by that point.

Are there any covenants in your neighborhood concerning replacing older windows?
