REHAU windows are typically priced through U.S. fabricators and dealers, not from one fixed national price list. A standard replacement window may cost about $700-$1,500 installed, while large, custom, or high-performance units can exceed $2,500; frame series, glass, dimensions, labor, and shipping drive the quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Standard replacement window | $700 | $1,100 | $1,700 | Installed; typical opening and access |
| Custom or oversized window | $1,400 | $2,400 | $4,000+ | Special dimensions, shape, or glazing |
| Window product only | $450 | $900 | $2,500+ | Fabricator quote; excludes installation |
| Installation labor | $250 | $450 | $900+ | Per window; varies by opening and finish |
What REHAU replacement windows cost by size
For a typical U.S. home, budget roughly $700-$1,700 per installed REHAU window when replacing a standard-size unit without major framing repairs. A whole-home project with 10-15 windows commonly falls around $8,000-$22,000, depending on dimensions, glazing, trim work, and regional labor rates.
Prices vary because REHAU supplies window profile systems that are made into finished windows by fabricators. The quote depends on the fabricator’s product configuration and installer rather than a universal REHAU retail price. Assumptions: standard white or neutral frame, ordinary access, midrange glass, and no structural changes.
A practical starting budget is $1,100 per standard installed window, before unusual options or repairs.
How frames, glass, and installation appear on quotes
Ask whether a quote covers the complete window, removal, disposal, interior and exterior finishing, and sales tax. Product-only prices are not directly comparable with installed bids. The ranges below are approximate per-window allowances; custom units may fall outside them.
| Quote component | Typical price | What changes the charge |
|---|---|---|
| REHAU-based window unit | $450-$2,500+ | Size, opening style, profile, color, and fabricator |
| Glass package | $100-$600 | Double or triple glazing, coatings, safety glass |
| Installation labor | $250-$900 | Access, removal, fit, and finish carpentry |
| Removal and disposal | $40-$150 | Old frame condition and local disposal charges |
| Trim, flashing, or repair | $50-$500+ | Water damage, trim replacement, or flashing scope |
Labor may be estimated by the opening or by crew time. For hourly work, a rough calculation is , with residential window installers often charging about $60-$110 per hour per worker when billed hourly. Confirm that installation, sealing, and finish work are included before comparing totals.
Which frame dimensions and glass specs raise the quote?
Window area is a major price driver. A unit around 3 by 5 feet is usually less costly than a 6-by-5-foot picture window, which uses more frame and glass and may require additional handling. Arched, angled, or unusually narrow openings also tend to need custom fabrication.
Glass specifications add cost as well. Triple glazing may add roughly $150-$500 or more per window compared with a basic double-pane configuration. Laminated or tempered safety glass, acoustic glass, decorative grids, and specialty colors can add another $75-$400 or more per unit. Energy performance depends on the full assembly and glass package, so buyers should compare documented U-factor and solar heat gain coefficient values, not frame branding alone.
Confirm the exact width, height, opening style, and glass specifications on the written estimate.
Regional labor and shipping change REHAU window totals
Labor and delivery can shift installed pricing substantially. Quotes in high-cost metro areas may run about 15%-30% above a comparable project in a lower-cost region; rural locations may instead face higher delivery or travel charges. Custom windows shipped from a fabricator can also require longer lead times and added freight, particularly for large or fragile units.
Cold-climate or coastal projects may specify different glass, air-sealing, or corrosion-resistant hardware options. These requirements do not automatically dictate a REHAU system, but can change the product package and installation detail. Compare local bids using the same window schedule and finish scope.
How long installation takes and what labor includes
A straightforward replacement often takes about 2-4 hours per window for a two-person crew, with a full home project taking one to three days. New construction, difficult upper-story access, oversized glass, or damaged framing can extend the schedule. Ask whether the installer protects floors, removes old units, insulates gaps, flashes the opening, and restores interior or exterior trim.
Repair work is often billed separately. Rot repair or reframing may add $150-$700 per opening, while extensive water damage can cost more. Permit fees are not typical for like-for-like replacements, but local rules may require permits when enlarging openings or changing structural components. Have suspected damage documented before approving a fixed installation price.
Three REHAU window quotes for common project sizes
These examples illustrate how scope affects a quote; they are not manufacturer list prices. A fabricator’s configuration and local labor market can produce different totals.
| Project | Product and labor | Estimated total |
|---|---|---|
| Five standard replacements | $700-$1,150 each installed | $3,500-$5,750 |
| Ten mixed-size replacements | $850-$1,600 each installed | $8,500-$16,000 |
| Four oversized custom units | $1,700-$3,200 each installed | $6,800-$12,800 |
The mixed-size example assumes ordinary removal and limited trim repairs. The custom example assumes specialty fabrication and more handling, but excludes major structural work. Use the window count and opening dimensions to check whether the quote’s unit price is plausible.
Compare REHAU with repair or simpler glass options
Before replacing a complete window, check whether the problem is limited to a failed seal, hardware, or sash. A hardware repair may cost about $100-$350, while glass replacement commonly runs $200-$600 per unit, depending on size and glass type. These repairs may not be practical if frames are damaged or the existing window is near the end of its service life.
For replacement, a simpler double-pane package can be less expensive than triple glazing or acoustic glass. Match performance to the home’s climate, noise exposure, and energy goals rather than paying for options that do not address a real need. Repairing a sound frame or avoiding unnecessary glass upgrades can lower the total substantially.
Lower the price by standardizing sizes and quote scope
Keep replacement dimensions close to existing openings where practical; enlarging an opening can add framing, siding, drywall, and permit costs. Choosing standard colors and common operating styles may also reduce custom fabrication charges. Scheduling several windows together can spread setup and travel expenses across the project.
Obtain at least three written bids with matching specifications, including profile or series, glass package, color, screens, removal, disposal, flashing, trim, warranty, and taxes. Ask for separate prices for optional upgrades and repairs. The most reliable savings come from comparing identical scopes, not from comparing an installed quote with a product-only price.
