The cost of Marvin Infinity windows varies by size, glass choice, and installation specifics. The main drivers are material package, frame and sash options, and project scope including labor and trim work. This guide presents cost ranges in USD to help buyers estimate a project budget and compare options.
| Item | Low | Average | High | Notes |

| Windows (per unit, installed) | $900 | $1,600 | $2,900 | Double-hung, standard glass, vinyl-looking Infinity fiberglass frame |
| Whole-project window replacement (per opening) | $1,800 | $3,200 | $5,500 | Includes removal, trim, and insulation |
| Labor (per window, install) | $400 | $900 | $1,600 | Calculated for 4–6 hours crew time |
| Materials & hardware | $200 | $500 | $1,000 | Glazing, shims, flashing, screws, fin bolts |
| Permits & inspections | $0 | $100 | $400 | Depends on jurisdiction |
| Delivery & disposal | $50 | $150 | $350 | Distance-dependent |
| Warranties & service plan | $0 | $100 | $400 | Optionally included or extended |
| Taxes & contingencies | $50 | $150 | $600 | Tax rate varies by location |

Overview Of Costs
Typical project ranges for Marvin Infinity windows span from moderate upgrades to full replacement projects. For a single standard window, installed cost commonly falls in the $1,000–$2,000 range, with higher-end configurations or larger sizes pushing toward $3,000 per unit. When replacing multiple openings in a home, the total project typically runs $3,000–$15,000 depending on quantity, customization, and framing conditions.
Per-unit pricing factors include frame style and performance package. Basic Infinity units with standard glass begin near $900–$1,200 per window, while upgraded glass, multiple housings, or decorative grilles move toward $1,600–$2,900 per unit installed. Extra work such as exterior trim refinishing or interior drywall work adds to the total.

What Drives Price
Major cost drivers include glass package selection (double pane vs. triple pane), U-factor and solar heat gain coefficient (SHGC), and frame finish. For Infinity windows, higher-efficiency glass or custom exterior colors raise per-unit pricing. Frame size and style influence labor time and material use, especially when retrofits involve substantial trim work or non-standard openings.
Niche specifications often add cost: larger openings may require structural adjustments, vinyl versus fiberglass trim, and upgraded hardware such as multi-point locks. In addition, the pitch of the installation area and the presence of masonry openings can alter both labor and materials budgets.
Assumptions matter: window count, wall construction, and whether the project is a straight replacement or a first-time retrofit. The numbers assume standard Midwest-to-Sun Belt climates and typical residential framing.
Regional Price Differences
Three regions show notable delta in Marvin Infinity window pricing due to labor markets and permitting costs. In the Northeast urban markets, project averages tend to be 8–15% higher than national baselines. In the Midwest suburban area, costs align with national averages but can lean 5–10% lower in some counties. In rural Southwest regions, installed prices may be 10–18% lower overall due to simpler access and lower crew rates.
Labor & Installation Time
Crews and durations vary by opening size and complication. A standard 3′ x 5′ window often takes 2–4 hours for a straightforward retrofit, including cleanup. A more complex install with masonry or extensive trim may require 6–8 hours per unit. Labor intensity directly influences total cost, particularly when multiple openings are replaced in a single visit.
Per-hour framing and fastening rates commonly run $60–$120 per hour for skilled installers in many markets, with higher-end labor in dense urban zones. When estimating, use a simple labor formula: labor hours × hourly rate. This helps compare bids that separate materials from labor.
Additional & Hidden Costs
Hidden costs can appear in the permit line, disposal fees, or need for exterior trim repainting after removal. If the existing frame requires repair or reinforcement, expect extra days of labor and additional materials. Some projects incur a contingency of 5–10% to cover unforeseen framing or water management issues.
Seasonal and scheduling factors affect availability and price. Installing in shoulder seasons (spring or fall) can reduce labor bottlenecks and may give access to contractor discounts. Delivery timing and backorder risks for Infinity components can also alter the total project window and price.
Real-World Pricing Examples
Scenario cards below illustrate typical outcomes for three project scopes.
Basic — 4 standard Infinity units, mid-range glass, no custom trim. Specifications: 4 double-hung openings, standard color, within a single-floor retrofit. Labor: 16 hours total; per-unit price around $1,000–$1,200 installed. Total: $4,000–$4,800. Assumptions: urban submarket, no structural work.
