Des Moines Window Pros provides professional aluminum window replacement in Des Moines, IA for residential and commercial properties across Greater Des Moines. Sash that will not stay up. Water tracking behind the stool. Single-glazed aluminum sliders from the seventies sweating onto the sill. That last one is why most people look up this phrase, and it is a diagnosis rather than a shopping list.
Where the water forms tells you what to buy. Sitting on the metal of the frame while the middle of the pane stays dry, it means the frame is the coldest thing in the room and no glass package changes that. Trapped between two lites, it is the sealed unit and a far cheaper fix.
The mechanism is conduction. The extrusion ties outside to inside with nothing interrupting it, so the indoor face of the frame tracks the weather. The state's figures for central Iowa put heating degree days near seven thousand one hundred against roughly eight hundred cooling, so that path runs against you for most of the year.
The fix, where aluminum stays, is a resin barrier cast into a channel milled through the frame, with the aluminum web across it machined away afterward. The outer half and inner half are then held together by something that is not metal. That is the whole of what thermally broken means.
Why residential aluminum fell out of favor follows from that. It arrived before the break did, it was cheap to extrude, and the market moved to frames that do not conduct in the first place. The material is not bad. An uninterrupted one is a bad frame.
On the code, Iowa leaves you exposed in an interesting way. The state energy code excludes the remodeling of one- and two-family dwellings from its scope, so no state ceiling attaches to your replacement and nobody will check the label. Do not read that as permission. And do not accept the reverse claim either, because nothing in this state bars aluminum and a thermally broken unit can hit whatever figure you specify.
Permits are local for the same reason. Iowa Code 103A.10 reaches only state-owned buildings, state-funded projects, jurisdictions that adopted the code by ordinance, and cities over fifteen thousand without a comparable local one. We confirm with the city Permit and Development Center before ordering, because a permit question answered after the glass arrives is an expensive question.
Lead matters here too. The stock carrying these sliders is usually pre-1978, and the frames often sit in painted wood openings. Work that disturbs that paint runs under EPA Lead-Safe Certified containment whichever way the job goes.
Aluminum stays right on the commercial side, with polyamide thermal struts in the framing, entrances with a ten-inch bottom rail, and tenant fit-outs where a landlord's allowance sets the scope. We do that work and we specify the break on it.
The recommendation. A new aluminum frame does not belong in a Des Moines bedroom. Where the slider is sound and the budget is short, an AERC-rated low-e storm panel over it buys real surface temperature for a fraction of a replacement. Where the frame is bare metal and finished, change the unit rather than reglazing a bridge.
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 aluminum window replacement
The difference between aluminum window replacement that lasts and aluminum window replacement 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.
