An all casement whole house replacement puts a crank-out window in every opening that opens, with the hinge sides planned across the house so the windows catch the breeze and clear the walkways, and picture units where you only want the view. JMB Builders measures every opening, orders the house as one order and installs it across the Twin Cities metro. Priced per opening. Send photos and we reply within one business day, or book a free in-home estimate.
- Hinge sides planned room by room before the order

Casements are the window most people pick when they have had both. The sash swings out on hinges and a crank pulls it shut against the weatherstrip on all four sides, so a closed casement seals tighter than a sliding sash. Open, the whole opening is clear, which is why a bedroom casement meets egress in a smaller frame than a double-hung of the same size. The screen is inside, so it stays clean.
The planning is the hinge side. Every casement hinges left or right, and the choice decides which way the sash swings over a deck, a walkway or a bush, and which way it catches the wind. On a whole house we walk each room at the measure and mark the hinge side on the plan, pairing windows so a two-casement opening swings open like a book. Wide openings get a picture unit in the middle with casements on the sides.
Then the house goes on one order, so frames, glass, grilles and crank hardware match. Casements in the same line match the picture units in frame width, so a wall of mixed units reads as one.

How it is priced: per opening
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Casements cost more per opening than double-hungs or sliders in the same line
- Size: tall casements and wide two- and three-unit combinations cost more and may need mulling
- Picture units in place of casements where a window never opens
- Frame material, color, glass package and grilles
- Crank and lock hardware finish
- Insert in sound frames vs. full frame with new trim
- Rot found when the old windows come out, priced as written on the quote
Send a photo of the outside of each window from a few steps back so we can see what the sash would swing over. That sets the hinge side.
How long it takes
Casements are usually built to order; the lead time is on the quote. Install runs two to five working days for most houses, with time at each window to adjust the sash and lock.

Situations and options
Casements everywhere they open
Every operating window is a casement. Single casements in bedrooms and baths, pairs in living rooms, hinge sides planned so pairs open like a book.
Picture units with casement flankers
Wide living-room and dining openings get a fixed picture unit in the center and a casement each side. Matching frame widths in one line keep the wall reading as a set.
Casements with awnings in baths
Awning windows are casements hinged at the top. In a bathroom or over a tub they vent in the rain and sit high for privacy, and they come from the same line.
All-Casement Whole-House Replacement: questions, answered
Can every window in the house be a casement?
Every window that opens, yes. Casements come in single, pair and triple units, and awnings from the same line cover high bathroom openings. Very wide openings usually get a fixed picture unit in the middle with casements on the sides, because a casement sash can only be so wide before it is too heavy for the hinges.
How do you decide which side a casement hinges on?
At the measure, room by room. The sash should swing away from a walkway, a deck chair or a grill, open toward the usual breeze if you can, and in a pair the two sashes hinge at the outside edges so they open like a book. We mark the hinge side on the plan and on every line of the quote.
Are casements good for bedroom egress?
They are the best window for it. A casement opens the whole frame, so the clear opening is nearly the frame size and a bedroom casement meets the egress size in a smaller unit than a double-hung or slider would need. We check the egress opening at every bedroom before the order.
Do casements cost more than double-hungs for a whole house?
Yes, per opening, in the same line. The hardware and the sash construction cost more. Across a whole house the gap is real, which is why some owners do casements in the rooms they open and picture units or double-hungs in the ones they do not.
Where do the screens go on an all-casement house?
Inside. A casement swings out, so the screen sits on the room side of the sash and stays out of the weather. In winter the screens can come out and be stored, which also lets more light through. Most lines offer a finer mesh that is less visible.
Will all-casement windows look right from the street?
A casement has clean vertical lines and no meeting rail across the middle, so a house of casements reads simpler than a house of double-hungs. Grilles can be added to match a traditional house. We hold samples up at the measure and photograph the street side so you can picture it.
