Des Moines Window Pros provides professional double-hung and single-hung windows in Des Moines, IA for residential and commercial properties across Greater Des Moines. The double-hung is the most common window in this city and by far the most over-replaced. Half the calls we take about them concern a sash that drops when you let go of it, and that symptom points at the balance rather than at the window around it.
On a post-1960 unit the balance is a cartridge or a spiral rod inside the jamb liner, and it is a stocked part. Swapping a pair of balances, a set of tilt latches and a worn liner costs a fraction of a new unit and takes under an hour once the sash is out. We quote that job and we do that job.
On a genuine weight-and-pulley window the answer differs but costs no more. New sash cord or chain, a cleaned pulley, a rebalanced iron weight and spring bronze at the parting bead will make a hundred-year-old sash run better than it has since the war, and it keeps the original glass in the house where it belongs.
Replacement wins on the failures that keep coming back. Meeting rails that no longer meet, so the lock will not throw. Bottom rails gone soft at the joint. Aluminum triple-track units where sash and storm have both given up. Nineties vinyl whose welded corners have opened at the sill. Those are not worth another service visit, and we will say so on the first one.
If you do replace, insist on a lock that pulls the rails together rather than one that merely holds them closed. A cam lock with a proper keeper compresses the weatherstrip at the meeting rail, which is the leakiest line in the whole assembly, and two locks across a wide opening is not an upsell here, it is the correct specification.
Insert versus full-frame is the other decision and it is mostly a money decision. An insert keeps your existing jambs and costs you two to three inches of glass. A full-frame tear-out costs more, disturbs the interior trim, and is the only honest option once the sill or lower jamb is rotten. We probe the sill before recommending either one.
Do not let anyone sell you triple glazing on a double-hung before the attic is finished. The third lite adds weight, which loads the balances, and it adds cost the same dollars would beat in insulation. Once the shell is tight it becomes a reasonable comfort upgrade on the coldest rooms, and we will happily price it then.
We will also tell you when the answer is simply weatherstripping. Quality sealant at the exterior casing, a new sash lock and a spring bronze retrofit at the stiles will fix a draft in a sound double-hung for a couple of hundred dollars. We would far rather do that than take four thousand dollars for work the house did not actually need.
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 double-hung and single-hung windows
The difference between double-hung and single-hung windows that lasts and double-hung and single-hung 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.
