Vancouver Window Replacement provides professional double-hung and single-hung windows in Vancouver, WA for residential and commercial properties across Southwest Washington. A double-hung has two sashes, two balance pockets and a meeting rail sitting in the middle of the glass. Every one of those is a place where air gets through, and it is why the type usually tests worst of the operables on both numbers the code cares about.
Section R402.4.2 caps fenestration air leakage at 0.3 cfm per square foot, tested under NFRC 400 or the joint AAMA, WDMA and CSA standard and labelled by the manufacturer. A hung window meets that figure with brush pile seals sliding against a jamb liner. A casement meets it by pulling a compression gasket shut against a stop. The two mechanisms are not equivalent, they do not age the same way, and the tested results reflect it plainly.
Which is why our default recommendation on a tall, narrow opening in Southwest Washington is to change the type entirely. A casement in that same rough opening will normally certify both tighter and lower, and on a house where you are also trying to land the whole batch under 0.30, that one swap is frequently what makes the numbers work without buying a single upgrade.
There are three good reasons not to swap and we take all of them seriously. The elevation has to match, because a street-facing wall of hung windows with one lonely casement in the middle looks exactly as wrong as it sounds. The opening sits over a walkway or a deck where a swinging sash becomes a head-height hazard. Or the house is old enough that its proportions are genuinely the point.
When a hung window is the right answer, the parts to interrogate are the balances and the jamb liner, not the glass. Constant-force coil balances comfortably outlast spiral balances in a house where the sashes actually get opened. A rigid jamb liner keeps the pile compressed after ten winters; a thin flexible vinyl liner relaxes, and a relaxed liner is a draught you cannot adjust out.
Single-hung deserves a mention because it is quietly the better buy in certain rooms. One fixed sash means one fewer balance system, less operating leakage area and a lower price for the same opening. In a bedroom where nobody has opened the top sash since the house was built, choosing single-hung is simply free money you can move elsewhere.
Tilt-in sashes are the feature people ask about and the one we genuinely support. In a two-storey house on a Clark County hillside lot, cleaning from inside is not a luxury, it is the only realistic option. The part to specify there is the tilt latch itself, in metal rather than moulded plastic, because that is the component that breaks.
If your existing double-hungs are sound in the frame and only the balances have given up, say so at the measure. Rebuilding balances and weatherstrip on a decent frame costs a fraction of a replacement, and no compliance calculation gets triggered at all.
Our licensed and insured team brings the right materials and equipment to every job — area-weighted U-factor across the replacement batch, NFRC 100 whole-product U-factor certification, warm-edge stainless spacer in a dual-seal sealed unit, the 0.3 cfm per square foot fenestration air leakage limit, pultruded fiberglass with a glass-matched expansion rate, welded uPVC sash with foam-filled chambers — and backs the work with a written workmanship warranty. We serve Vancouver and nearby communities including Camas, Washougal, Battle Ground, Ridgefield.

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 area-weighted U-factor across the replacement batch, NFRC 100 whole-product U-factor certification, warm-edge stainless spacer in a dual-seal sealed unit, the 0.3 cfm per square foot fenestration air leakage limit, 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 Vancouver 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 Southwest Washington means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Vancouver Chooses Vancouver Window Replacement
- ✓Every quote carries the area-weighted U-factor for the whole batch, because that is the figure the code is actually asking about
- ✓We tell you which openings belong in the same order, since the average is taken across the units on one job and phasing costs money
- ✓We will not install an unlabelled unit, because Table R303.1.3(1) assigns it a default U-factor and that default fails on the spot
- ✓We quote the sealed unit before the window, and we will take the smaller job when the sash and the hardware are sound
