Window Trim Replacement Cost: $350–$1,600 (Average $900) per Window in 2026

Author: CostGuideHQ Editorial·✓ Fact-checked·Updated July 2026·7 min read·6 sources·US national averages, USD
Quick answerQuick answer: Replacing window trim costs $350 to $1,600 per window, averaging around $900 nationally. Small single-hung windows run near the low end; bay and bow windows run $800 to $1,600. Material (wood, vinyl, PVC, or composite) and whether the job is interior or exterior drive the rest of the spread.
  • Window trim replacement averages $900 per window nationally, with a typical range of $350 to $1,600 depending on window size (HomeAdvisor, Angi).
  • Bay and bow windows cost the most to trim, $800 to $1,600 installed, versus $350 to $650 for single- or double-hung windows (HomeAdvisor, Angi).
  • Interior trim materials (hardwood, MDF, polyurethane) and exterior-rated materials (vinyl, fiber cement, cellular PVC) are priced separately, since exterior casing has to handle weather that interior casing never sees (This Old House).
  • Rotted wood casing or frame repair runs $150 to $800 depending on how much material has to be cut out and replaced (HomeAdvisor).

What affects the cost?

  • Window size/type, installed — single-hung $350-$600, double-hung $400-$650, picture window $500-$900, bay window $800-$1,500, bow window $900-$1,600 (HomeAdvisor, Angi)
  • Interior vs. exterior material — interior casing typically uses hardwood ($0.75-$5.50/linear ft), reclaimed wood ($1.25-$12), MDF ($0.60-$7), or polyurethane ($2-$6), while exterior casing needs weather-resistant vinyl ($0.80-$30), fiber cement ($0.70-$5.50), cellular PVC ($0.50-$5), or wood ($1-$10) (This Old House)
  • Trim style/profile — colonial runs $0.62-$0.92 per linear foot, craftsman $0.82-$1.94, architectural $1.57-$16.62, and traditional profiles span $0.52-$24.78 (Fixr)
  • Labor rates — trim carpenters charge $66-$121/hour and handymen $37-$68/hour for casing work (Fixr), while HomeAdvisor's broader trim-installation page cites a similar $75-$125/hour
  • Old trim removal and disposal, typically $50-$150 per window (HomeAdvisor, Angi)
  • Rot damage — repairing a rotted wood window frame/casing runs $150-$800 depending on extent, and cost varies by material: wood $100-$350, aluminum $150-$350, vinyl $150-$500, fiberglass $300-$600, composite $400-$800 (HomeAdvisor)
  • Finishing — painting or staining unfinished trim adds $1-$6 per linear foot, or roughly $50-$150 in minor touch-up repairs per window (Angi, HomeAdvisor)
  • Permits — required in some areas, typically $25-$150 (HomeAdvisor, Angi)

How much does window trim replacement cost?

Replacing the trim around a window costs $350 to $1,600, averaging around $900 nationally (HomeAdvisor, Angi). Window size and shape set most of that spread: a single-hung window runs $350 to $600 installed, a double-hung $400 to $650, a picture window $500 to $900, a bay window $800 to $1,500, and a bow window $900 to $1,600 (HomeAdvisor, Angi). Two separately published sources land on identical figures here, which makes the window-specific number more reliable than a general “trim installation” estimate. Fixr’s own window-trim page reports a much lower average, $176 per window with a $36 to $191 range — that reads like the cost of basic casing material and roughly an hour of labor for a couple of standard windows, not a full job that includes removal, multiple window sizes, and finishing. If a quote comes in dramatically under $350, ask what’s excluded.

What affects the cost?

  • Window size and shape. Larger, non-standard windows take more material and more precise cuts — bay and bow windows cost more than double a single-hung window (HomeAdvisor, Angi).
  • Interior vs. exterior material. Interior casing can use hardwood, reclaimed wood, MDF, or polyurethane ($0.60 to $12 per linear foot in materials), while exterior casing needs weather-rated vinyl, fiber cement, cellular PVC, or wood ($0.50 to $30 per linear foot) (This Old House).
  • Trim profile. A plain colonial profile runs $0.62 to $0.92 per linear foot, craftsman-style $0.82 to $1.94, and detailed architectural profiles $1.57 to $16.62 (Fixr).
  • Labor rates. Trim carpenters charge $66 to $121 per hour and handymen $37 to $68 per hour (Fixr); HomeAdvisor’s broader trim page cites a similar $75 to $125 per hour.
  • Old trim removal. Tearing out and hauling away the old casing typically adds $50 to $150 per window (HomeAdvisor, Angi).
  • Rot or water damage. Repairing rotted casing or frame material runs $150 to $800 depending on how much has to be cut out and rebuilt (HomeAdvisor).
  • Finishing. Painting or staining unfinished trim adds $1 to $6 per linear foot on top of the installed price (Angi, HomeAdvisor).

Wood vs. PVC vs. composite: which material costs less?

On raw material cost alone, cellular PVC is the cheapest exterior-rated option at $0.50 to $5 per linear foot, fiber cement composite runs close behind at $0.70 to $5.50, and exterior wood spans $1 to $10 (This Old House). Vinyl has the widest range of any material, $0.80 to $30 per linear foot, because it covers everything from plain flat stock to detailed profile trim. For interior-only casing, the calculation is different: hardwood runs $0.75 to $5.50 per linear foot, reclaimed wood $1.25 to $12, MDF $0.60 to $7, and polyurethane $2 to $6 (This Old House) — none of those interior materials are rated for exterior exposure, which is why interior and exterior casing get swapped out on separate schedules even on the same house. Wood costs about the same as PVC or fiber cement up front, but wood is also the material most likely to show up in the rot-repair numbers above; PVC and composite skip the recurring paint and caulk cycle that keeps wood casing looking (and performing) like new.

How to lower your window trim replacement cost

  • Match the material to the location. Don’t pay for exterior-rated vinyl or PVC on an interior window — hardwood or MDF casing inside runs as low as $0.60 per linear foot (This Old House).
  • Stick with a standard window shape where you have the choice. Single- and double-hung windows cost roughly half of what a bay or bow window costs to trim (HomeAdvisor, Angi).
  • Choose a plain profile over an architectural one. A basic colonial profile runs $0.62 to $0.92 per linear foot versus $1.57 to $16.62 for detailed architectural trim (Fixr).
  • Repair instead of replace when rot is limited. Patching damaged casing costs less than a full tear-out and reinstall, though the frame material still affects the repair price (HomeAdvisor).
  • Remove the old trim yourself if it’s safe to do so, avoiding the $50 to $150 per-window removal fee (HomeAdvisor, Angi).

Prices vary by region, window size, and material availability, so treat the figures above as a planning budget. Get a couple of quotes, especially for bay or bow windows, and confirm whether removal, finishing, and any rot repair are included before signing off on a final number.

Frequently asked questions

How much does it cost to replace window trim?
Most homeowners pay $350 to $1,600 per window, averaging around $900 nationally (HomeAdvisor, Angi). The exact number depends heavily on window size and shape — a single-hung window runs $350 to $600, while a bow window can reach $1,600.
Does window size change the price that much?
Yes. Installed trim costs $350 to $600 for a single-hung window, $400 to $650 for a double-hung, $500 to $900 for a picture window, $800 to $1,500 for a bay window, and $900 to $1,600 for a bow window (HomeAdvisor, Angi).
What's the difference between interior and exterior window trim?
Interior trim (the casing you see from inside the room) can use hardwood, reclaimed wood, MDF, or polyurethane, priced $0.60 to $12 per linear foot in materials. Exterior trim needs weather-resistant material — vinyl, fiber cement, cellular PVC, or wood — priced $0.50 to $30 per linear foot (This Old House).
What's the cheapest material for window trim?
Cellular PVC is the least expensive exterior-rated material at $0.50 to $5 per linear foot in materials, with fiber cement close behind at $0.70 to $5.50 (This Old House). For interior work, MDF and hardwood run $0.60 to $7 and $0.75 to $5.50 respectively.
How much does it cost to fix rotted window trim instead of replacing it all?
Rot repair runs $150 to $800 depending on how much wood has to be cut out, and the material used to patch it matters too — wood patches run $100 to $350, vinyl $150 to $500, composite $400 to $800 (HomeAdvisor).
How much does labor cost for window trim installation?
Trim carpenters charge $66 to $121 per hour and handymen $37 to $68 per hour for casing work (Fixr), while HomeAdvisor's broader trim-installation page cites a similar $75 to $125 per hour.
Does the price include removing the old trim?
Usually not — it's typically a separate line item. HomeAdvisor and Angi both put old trim removal and disposal at $50 to $150 per window.
Why do window trim cost estimates vary so much between sources?
HomeAdvisor and Angi both land on the same $900 average and $350-$1,600 range for window-specific trim work, but Fixr's own window-trim page reports a much lower $176 average — its numbers read like basic casing material and about an hour of labor for a couple of windows, not a full replacement job with removal and finishing included.

HomeAdvisor and Angi (Angi owns HomeAdvisor and the two sites frequently publish matching cost content) report identical window-trim-specific figures: national average $900 per window, typical range $500-$1,200, full range $350-$1,600, and the same breakdown by window type (single-hung through bow window). Fixr reports a much lower headline for its own 'window trim installation' page -- national average $176 per window, typical range $164-$187, full range $36-$191 -- which reads as basic casing material plus roughly an hour of labor for a couple of standard windows, not a full trim replacement job with removal, multiple window sizes, and finishing folded in. HomeAdvisor's separate general trim-installation page (which covers interior AND exterior trim of every type -- baseboard, crown, casing -- not window-specific) reports $1,389 average, $634-$2,263 range, and is cited as cross-check context rather than a headline anchor, since it isn't scoped to window casing alone. national_average_usd and the range are anchored to the HomeAdvisor/Angi window-trim-specific consensus, the most directly comparable per-window figure available across two separately published sources. by_type window-size rows come from that same HomeAdvisor/Angi table; the material rows (interior vs. exterior) come from This Old House, which cleanly separates interior-only materials (hardwood, reclaimed wood, MDF, polyurethane) from exterior-rated materials (vinyl, fiber cement, cellular PVC, wood). Figures generally cover material plus standard installation labor for the casing/trim boards around one window; old-trim removal, rot/frame repair, painting, and permits are commonly quoted as separate line items. This guide covers window casing and trim specifically -- the decorative boards framing a window, interior or exterior -- distinct from exterior trim as a whole-house siding job (fascia, corner boards -- see exterior-trim-installation-cost), the window sill component alone (window-sill-replacement-cost), and interior crown molding (crown-molding-installation-cost).
