Why would I reuse old windows in a new build?

Well, if you're building a new house and you don't care about historical integrity, you're not.

But, if you're rebuilding a late 1700's cape from the Cape (Cape Cod, MA), you are DEFINITELY going to be installing the original windows.

It comes down to character. Putting new windows in an old building like this would be like dressing up in a suit to go to prom and wearing sneakers. They are so integral to the character and historical appearance of this structure. That and the fact that they were maintained and repaired over the years, they are in such good shape why wouldn't you?

If you're worried about energy efficiency, there are a few things you can do that make a difference. Number one is keeping up with building maintenance, painting, caulking, and reglazing the windows every ten years or so. A lot of old windows I see were last reglazed in 1956 and they've been suffering in the sun and rain, leaking, rotting, and letting cold air in. Often, they are beyond repair, and the best route would be to talk to someone like Erik Squire of Squire Custom Millworks in Machias, who can build a brand new historic window from scratch. He even sources antique glass for discerning customers.

Number Two would be installing lexan or plexiglass "storm windows" on the inside or outside to keep the wind out and protect the paint and glazing from the elements. You might remove these strategically in the summer to open the windows and get some ventilation.

Number three would be using heavy drapes on the inside. In addition to the properly maintained windows and lexan, drapes would add another layer of protection from the cold and increase comfort on those cold winter days when the furnace is running the fire is blazing in the fireplace.

Although these old windows will never be as weather tight as a triple glazed energy efficient Marvin window for example, they will last a lot longer with proper maintenance. After all, some of the windows we are installing on the Higgins House Historic Rebuild in East Machias are 250 years old. You can't argue with that. By comparison, I defy any manufacturer of vinyl windows to claim their product will last that long. Vinyl degrades in the sun, the seals fail, and after 30 years that tight window is no longer keeping the cold out. The other thing is there's really nothing you can do to fix it. When its time, you are looking at a costly window replacement.

So, why would you install these old windows? If you care about the houses character, and you're willing to do a little work, these windows will protect your house long after you're gone.
