Best for: Traditional homes; easy top-and-bottom cleaning access
The most common replacement window in American housing, and the default in most homes built before about 1990. Two sashes stacked vertically in a single frame; both operate, and on modern units both tilt inward for cleaning from inside the house.
When double-hung is the right choice
It’s usually right when you’re matching what’s already there. Double-hung reads correctly on traditional architecture — colonials, foursquares, farmhouses, brick ranches, and virtually every pre-war home in Nashville and Knoxville. Swapping to a different operating style on a historically consistent facade tends to look wrong even when people can’t articulate why.
It’s also the practical choice on upper floors. Both sashes tilt in, so second- and third-story windows get cleaned from inside rather than from a ladder.
It’s the wrong choice when ventilation is the priority. A double-hung opens to a maximum of half its area, and the sash itself sits in the airflow. If you’re replacing a window over a kitchen sink or in a room that needs to move air, ask about casement instead.
What’s different about installing a double-hung
This is the style where shimming discipline shows up fastest. A double-hung has two moving sashes riding in balance channels, and those channels are only parallel if the frame is set true. A frame that bows even slightly under fastening pressure will bind one sash, usually at the top of its travel, and put uneven load on the balances.
The result gets reported as “the window is defective.” It usually isn’t. It’s an installation that pulled the frame out of plane.
The second thing specific to this style is the balance system — the mechanism that holds a sash where you put it. It’s warranted for life by ProVia, but only against defects. A balance struggling against a bowed frame will wear out early, and that’s an install problem the product warranty doesn’t cover.
We shim at every fastening point and verify the frame is square before fastening, then operate every sash before the job is signed off. One-handed operation is the field test. Here’s the full standard.
What we install
