Des Moines Window Pros provides professional custom window installation in Des Moines, IA for residential and commercial properties across Greater Des Moines. The 2019 to 2023 American Community Survey puts about 27,000 of Des Moines' roughly 97,000 housing units at 1939 or earlier. In that stock the custom question is usually somebody asking us to reproduce a decorative lite.
Our first answer is normally not to. An original leaded or art-glass transom can be taken out, releaded where the cames have sagged, and reset into a new frame, or left in place while the operating sash below it is replaced. A reproduction costs more than the restoration and still reads wrong from the sidewalk, because the glass itself is not made the same way anymore.
Where a made-to-order unit is genuinely the answer: a rotted round-top, a bay with angled flankers, an oversized stair-landing lite, or a foursquare front window whose size has no catalog equivalent. Those get templated, not measured. Measurement in a hundred-year-old house is a discipline of its own anyway, since a finished unit cannot be trimmed on site and a custom one cannot be exchanged.
Lead changes the order of operations, and on this stock it almost always applies. Taking a template means disturbing paint, so containment goes up before the tape comes out, and the work runs under EPA Lead-Safe Certified practice: poly down, the opening contained, the debris bagged at the opening rather than carried through the house.
Local historic district rules add a step on some blocks here, because exterior work is reviewed before a saw touches anything at all. That review runs on its own calendar, it sits ahead of the fabrication calendar rather than beside it, and a one-off ordered before the decision arrives is a unit you may own and still not be cleared to install.
The permit question has no statewide answer in Iowa. Iowa Code 103A.10 makes the state building code apply only to state-owned buildings, projects built with state money, jurisdictions whose governing body adopted it by ordinance, and cities over fifteen thousand people lacking a comparable local code. Here it is the city's call, and we confirm with the Permit and Development Center before anything is ordered.
Do not let a bidder quote you an Iowa energy requirement on this work either. The state energy code writes the remodeling of one- and two-family dwellings out of its own scope, so there is no state U-factor to meet and no solar heat gain ceiling to clear. The label still matters. You are simply the only person who will read it.
The recommendation, which costs us a line on the quote more often than not. Much of the old-growth wood sash in this city is sound, and sound sash with a storm panel hung over it will outperform a bad replacement and outlast a good one. So buy a one-off where the shape is already gone. Repair, reglaze or relead where it is not, and keep the original glass in the opening it was made for.
Our 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 custom window installation
The difference between custom window installation that lasts and custom window installation 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.
