Replace All the Casements That No Longer Crank
The casements were the first to go: the cranks grind, the sashes sag and will not pull tight, and the seals leak.

To replace all the casements that no longer crank, JMB Builders lists every crank-out window in the house, usually three to eight, and puts them on one order while the sliders, picture windows and double-hungs stay. One style across the house is a normal job for us, priced per opening, matched to the windows you keep. Twin Cities metro. Send photos and we reply within one business day, or book a free in-home estimate.
- Every casement in the house on one order, priced per opening
- The other styles stay and are matched at the measure
- New casements crank, lock and seal again
In a lot of houses the casements wear out before anything else. A crank-out sash hangs on hinges and an operator arm, and after enough years the gears strip, the arm bends, the hinge track wears and the sash drops. Then the sash does not pull tight to the seal, the window drafts, and the glass fogs when the seal finally lets go. The fixed and sliding windows next to them have no moving parts to wear and are still fine.
So replace the casements and leave the rest. Three to eight casements across the house go on one order in one frame color, glass and grille pattern. They go in as inserts where the frames are sound and full frame where a sill has rotted under a sash that never closed right.
The match is to the windows that stay. At the measure we note the frame color, grille pattern, glass tint and interior finish of the sliders and picture windows you keep, and order the casements in the closest current line. Some owners take the chance to switch one or two to a different style, such as a double-hung where a casement always hit the deck railing. That still goes on the same order.

How it is priced: per opening
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- How many casements and the size of each, tall or twin units most of all
- Insert into sound frames or full frame where the sill under a sash has rotted
- Brand, series, frame material, glass package and grilles
- Any casement switched to a different style, such as a double-hung or awning
- Hardware finish, and whether you want the cranks to fold flat for blinds
- Second-story casements that need a ladder set or roof brackets
- Interior finish: trim kept, new stops, or new casing
Note on each photo whether the window still cranks, locks and seals. That tells us which frames are likely sound for an insert.
How long it takes
Lead time depends on the line and is written on the quote. Three to eight casement inserts: one to two working days, every opening closed the day it is opened.

Situations and options
Casements for casements
The same style back in the same openings, with new operators, multipoint locks and fresh seals. The least visible change and the tightest-sealing window going back in.
One or two switched to double-hung or awning
A casement that always swung into the deck railing or the walkway comes back as a double-hung or an awning in the same opening, in the same color and glass as the rest of the order.
Casements plus the fogged picture window
If one fixed unit has lost its seal too, it goes on the same order. Mixed styles on one order is normal, and it keeps the glass tint the same across the wall.
Replace All the Casements That No Longer Crank: questions, answered
Can I replace just the casement windows and keep the rest?
Yes. Replacing one style across the house is a normal job for JMB Builders, usually three to eight casements on one order, each priced per opening. The sliders, picture windows and double-hungs you keep are checked at the measure so the new casements match them in color and grilles. Send photos and we reply within one business day, or book a free in-home estimate.
Why did my casements wear out before my other windows?
A casement has a crank operator, an arm, hinges and a track, and all of them move every time it opens. Gears strip, arms bend, hinge tracks wear and the sash drops until it no longer pulls tight. A slider or a fixed window has almost nothing to wear, so it lasts longer in the same house.
Is it worth fixing the cranks instead of replacing the casements?
If the glass is clear, the sash is straight and the frame is sound, a new operator can be the right fix for one window, and we do that work. When several casements have stripped cranks, sagging sashes and fogged glass together, the parts add up to most of a new window without the new seal and glass, and replacing them as a set is the better buy.
Can the new casements match my sliders and picture windows?
Usually close, and we check at the measure. Frame color, grille pattern, glass tint and interior finish of the windows you keep are noted, and the casements are ordered in the closest current line. If the old line is gone, we show you where the new ones will differ before you sign.
Can I switch a casement to a double-hung on the same order?
Yes. Mixed styles on one order is normal. A casement that hit a railing or sat over a walkway can come back as a double-hung or an awning in the same opening, in the same frame color and glass as the casements on the order.
How long does it take to replace all the casements?
Three to eight casement inserts usually take one to two working days, moving room to room. Full-frame installs where a sill has rotted, or second-story casements that need a ladder set, add time. Each opening is removed, set, sealed and trimmed the same day.
