Wood & Fiberglass Window Replacement cost (2026)
Wood and fiberglass window replacement costs $10,000–$25,000 in 2026, or about $17,500 for a typical job. Whole-home window replacement with premium wood or fiberglass windows — higher cost, better looks and longevity. That national figure is the starting point — labor rates, climate and permit fees move it, so a wood and fiberglass window replacement in San Jose prices differently than in El Paso.
Most jobs land around $17,500 nationally; your local price will differ.

Wood & Fiberglass Window Replacement cost by efficiency tier
Frame material sets the price and the look. Fiberglass is durable and low-maintenance; wood (often clad in aluminum outside) offers the richest appearance but costs more. The glass package adds on top. Prices are per window installed.
| Tier | National 2026 range |
|---|---|
| Fiberglass frame (double-pane low-E)Strong, stable, very low maintenance | $600 – $1,400 |
| Wood frame / aluminum-clad woodPremium look; needs periodic finishing | $1,000 – $2,200 |
| Triple-pane premium (wood or fiberglass)Top efficiency and sound control | $1,400 – $2,800 |
Where this number comes from
The 2026 national range for wood and fiberglass window replacement ($10,000–$25,000) is anchored to published industry, contractor and manufacturer pricing for the equipment plus typical installation labor. City pages take that range and adjust it three ways: the labor share is repriced from BLS OEWS metro trade wages where available and the BEA Regional Price Parity index elsewhere, the windows load is adjusted for the IECC climate zone, and a typical local permit fee is added.

How long does wood and fiberglass window replacement last?
Fiberglass lasts 30–50+ years; well-maintained wood can match it, but neglected wood rots far sooner.
Fiberglass is nearly maintenance-free. Wood (and the exterior of clad units) needs periodic repainting or re-staining and seal checks.
Signs you need wood and fiberglass window replacement
- Windows stick, swell, or are hard to open and close
- Fog or condensation appears between the panes (the seal has failed)
- Wood frames show rot, soft spots, peeling paint, or water staining
- You feel drafts near the window when it's shut
- They're single-pane originals and energy bills are high
- Visible warping, cracking, or daylight around the sash
- Outside noise comes through easily
Repair or replace?
Repair if…
- The wood frame is structurally sound and just needs refinishing or minor rot repair
- Only the seal, weatherstripping, or hardware has failed
- It's a historic or character window worth restoring
- The unit is under warranty
Replace if…
- Condensation is sealed between the panes (the IGU seal is gone)
- Rot has spread into the structural frame or sill
- They're single-pane and you want major energy savings
- Several windows are failing — bulk replacement lowers per-window cost

Questions to ask Windows contractors
Ask every bidder the same questions in the same order — differences in the answers explain differences in the price far better than the totals do.
- 1Is this a full-frame replacement or an insert (pocket) install?
- 2What's the glass package — double vs. triple pane, low-E coating, gas fill?
- 3Are disposal, trim, and exterior caulking/flashing included?
- 4Are the windows ENERGY STAR rated for my climate zone?
- 5What's the warranty on the frame, glass seal, and the installation labor?

30–50 years is the typical service life. Fiberglass lasts 30–50+ years; well-maintained wood can match it, but neglected wood rots far sooner. Budget $25–$150 a year for maintenance.
Should I repair or replace?
Wood windows are often worth restoring if the frame is solid — repair rot and reglaze rather than replace. Switch to full replacement once rot is structural or the seals are failing across many units. Repair makes sense when the wood frame is structurally sound and just needs refinishing or minor rot repair. Replace when condensation is sealed between the panes (the igu seal is gone).
When is the cheapest time for wood and fiberglass window replacement?
The best window is late fall and winter, when demand drops and installers discount — typically 5–15% off peak pricing. Avoid spring and summer peak.
