Des Moines Window Pros provides professional casement and awning windows in Des Moines, IA for residential and commercial properties across Greater Des Moines. On a casement the frame usually outlives the hardware by twenty years, so the honest first question is whether you need a window or a crank. We stock operators, hinge arms, keepers and multipoint locks, and we will fit them rather than sell you a unit.
The reason casements are worth having in a heating climate is the way they close. A hinged sash pulls into a compression seal all the way round, where a slider or a hung window has to rely on a sliding weatherstrip that wears. That is why casement air-leakage ratings on the NFRC label usually beat every other operating style in the same line.
It is also why the hardware takes the punishment. A dual-arm operator lifts and pulls a heavy insulated sash against that seal several hundred times a year, and the gearbox, not the vinyl, is what wears out. A worn operator lets the sash sit proud of the seal, and the draft you feel is a mechanical fault, not a glazing fault.
So we diagnose before we quote. If the sash still closes square and the corner joints are tight, you are looking at an operator, a hinge track, a set of roto keepers and new weatherstrip. That is a service call. If the sash has racked, the corners have opened, or the frame is out of plane, no hardware will pull it shut and the unit is finished.
Awning units get their own conversation because of where they sit. Over a kitchen sink, high in a bathroom, or in a basement bay, they are often the only ventilation in the room, and a stuck awning is a moisture problem before it is an energy problem. Fixing the operator on those is close to always the right call.
The bigger money question stays the same as everywhere else on this site. A run of casements across a great room can price out past what it would cost to air seal the attic plane, insulate to R-49 and deal with the band joist, and the second package will do more for how the room feels in January than the first one will.
When replacement is right, specify the hardware rather than accepting whatever the line ships with. Stainless hinge tracks instead of plated steel, a multipoint lock on anything over about thirty inches wide, an egress-clear hinge if the opening is in a bedroom, and an operator you can still buy a spare gearbox for in eight years' time.
Screens on a casement hang inside the room rather than outside, which surprises people and changes the order of work. We check the screen frame and the roto gear together, because a bent screen frame fouling the crank handle is a five-minute fix that has been mistaken for a failed window more than once in the houses around this city.
Our licensed and insured team brings the right materials and equipment to every job — dense-pack cellulose and attic top-plate air sealing done ahead of glass, AERC-rated low-e interior and exterior storm panels, warm-edge spacers in replacement insulated glass units, pultruded fiberglass lineals with a glass-matched expansion rate, polyamide thermal struts in commercial aluminum framing, EPA Lead-Safe Certified containment on pre-1978 openings — and backs the work with a written workmanship warranty. We serve Des Moines and nearby communities including West Des Moines, Ankeny, Ames, Urbandale.

Materials, equipment and how we do casement and awning windows
The difference between casement and awning windows that lasts and casement and awning windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with dense-pack cellulose and attic top-plate air sealing done ahead of glass, AERC-rated low-e interior and exterior storm panels, warm-edge spacers in replacement insulated glass units, pultruded fiberglass lineals with a glass-matched expansion rate, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Des Moines job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in Greater Des Moines means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
