Wood Window Options: Primed, Clad, Insert and Divided-Lite
Primed-for-Paint Wood Windows
A primed window arrives with a base coat only, and the finish coats are your job or the painter's. The clock starts early: one manufacturer's finishing guide says a primed exterior must be painted within 14 days of installation or exposure to weather, and a primed interior right after installation. Line up the painter before install day. Ask whether the quote includes painting or stops at the primer.
Aluminum-Clad Wood Windows
Clad windows keep exposed wood on the inside and wrap the outside in aluminum, vinyl or fiberglass for weather resistance. Cost guides say cladding can add years and efficiency, and it adds to the material bill. On an older house, look closely at the corners: the National Park Service notes that clad windows can show joints in the cladding that make them look very different from a painted wood window.
Wood Insert Windows for Old Frames
An insert (pocket) window fits inside the existing frame, so the interior casing and exterior trim stay put. Survey data says inserts usually cost less because the frame is reused. Soft or rotted jambs rule it out. Whether an insert or a full-frame tear-out fits your openings is a measuring question.
Simulated Divided Lites on Wood Sashes
Simulated divided lites (SDL) copy the look of old multi-pane sashes on a single insulated glass unit. The Park Service's replacement-window guidance describes the version that comes closest: a three-dimensional grid outside, spacers between the panes and a grid inside, with the outer grid matching the old muntin profile and fixed tight to the glass. Ask which grid the quote includes.

Wood Window Cost: What Moves the Price
National guides price wood above vinyl at every size, and the window type swings the number more than anything else:
Hopper
$150 to $350, the cheapest wood unit.Double-hung
$400 to $1,000.Casement
$600 to $2,000; cranks and hinges add to the price.Bay or bow
$1,500 to $7,500, often with two installers.Quantity
ordering 10 or more can cut the per-window price by around 20%.Old-window disposal
$50 to $200 if the contractor lists it separately.
Survey figures come in lower than range guides: homeowners in one 2026 survey paid about $544 per installed wood window, against $472 for vinyl. Repair is cheaper up front, around $400 against $1,200 for a new wood unit in one guide, and makes sense when the frame is sound and only hardware or a seal has failed.
Wood Windows in Lowell's Pre-1940 Housing
Two rules come with an older Lowell house:
Lead paint
Pre-1978 homes need lead-safe work when sashes and stops come out.Historic districts
A house in one of the city's review districts may need Historic Board review before exterior windows change, and restoring the old sashes is sometimes the better answer.
On lifespan the guides disagree. One puts wood at 30 to 60 years and calls it the longest-lasting, easiest-to-repair frame; an older NAHB study put it at upwards of 30 years; another guide gives the longevity title to fiberglass. They do agree on upkeep: wood needs more maintenance than other frames and can rot, so budget for paint.
On the order itself, one 2022 contractor note put wood lead times at 20 weeks or more when supply was tight. Ask for a current ship date in writing before you plan around a season.
