Marvin Infinity replacement windows typically cost about $1,000-$2,200 per window installed, while older Integrity models may cost roughly $700-$1,600 when available. The final quote depends on the specific model, window size, glass package, installation method, location, and whether the comparison is between current products or legacy Integrity units.
Marvin has reorganized its product lines, so “Integrity” often refers to discontinued or older models rather than a directly orderable current line. The ranges below are planning estimates, not manufacturer price lists.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Infinity replacement window, installed | $1,000 | $1,550 | $2,200 | Typical standard-size opening and ordinary access |
| Integrity legacy window, installed | $700 | $1,100 | $1,600 | Availability, condition, and exact model vary |
| Infinity window, unit only | $600 | $1,000 | $1,500 | Before installation, trim, or repair work |
| Ten-window Infinity project | $10,000 | $15,500 | $22,000 | Assumes standard openings and full-frame or insert work as quoted |
What Infinity and Integrity windows usually cost
For a typical standard-size double-hung or casement replacement, Infinity pricing often falls around $600-$1,500 for the window and $1,000-$2,200 installed. A homeowner replacing 10 units might budget $10,000-$22,000, with a middle estimate near $15,500. Oversized, custom-shaped, or difficult-to-access units can exceed these ranges.
Integrity pricing is less straightforward because many units were sold under older product names and may no longer be available as new, like-for-like replacements. Where comparable legacy stock or a current equivalent can be sourced, a reasonable installed planning range is $700-$1,600 per opening. A quote near the low end generally assumes standard sizes, uncomplicated access, and limited interior or exterior trim work.
For a new project, compare Infinity with the current Marvin line that matches the specific Integrity model’s materials and configuration, not just with the older brand name. Integrity included different construction types over time, so an older wood-interior model is not automatically equivalent to a fiberglass-only unit.
Assumptions: Standard residential openings, midrange glass and hardware, typical U.S. labor, and no major structural repairs. Local quotes can vary substantially.
How window materials, installation, and trim shape the quote
A window estimate combines the product, installation labor, removal, finishing, and sometimes permits or repairs. Ask the contractor to list each charge so that an Infinity quote can be compared fairly with a legacy Integrity replacement or another Marvin product.
| Quote component | Typical price | What changes the charge | How to compare |
|---|---|---|---|
| Window unit | $600-$1,500 each | Size, operation, glass, finish, and grille options | Match dimensions and options |
| Installation labor | $250-$700 per opening | Insert versus full-frame work, crew time, and access | Confirm what removal and finishing include |
| Removal and disposal | $50-$150 per window | Old frame type, disposal distance, and job minimum | Check whether it is already included |
| Trim or opening repairs | $100-$600 per opening | Rot, water damage, casing, and siding details | Request an allowance or itemized rate |
| Permits and overhead | $0-$300 per project | Local rules, administration, and contractor policy | Verify permit requirements locally |
Labor can be estimated using . At approximately $75-$125 per installer-hour, a straightforward replacement taking 2-4 labor hours may represent $150-$500 in labor before crew minimums, travel, removal, and company overhead. A full-frame installation may require more time because the existing frame and interior or exterior trim need additional work.
The biggest comparison mistake is treating a unit-only price as equivalent to an installed quote. Confirm whether each bid includes measuring, delivery, removal, disposal, flashing, insulation, interior trim, exterior repairs, cleanup, and sales tax.
Which glass, size, and installation details raise the price?
Window dimensions and style have a direct effect on both material and labor costs. A standard unit around 3 by 5 feet is generally less expensive than a large picture window or a custom shape. Moving from a standard opening to a unit wider than roughly 4 feet or taller than 6 feet can add several hundred dollars or more, especially when the opening needs reinforcement or extra handling.
Operation also matters. A basic double-hung or fixed unit may cost less than a casement, bay, bow, or specialty-shaped window. Bay and bow configurations can require structural support, more trim, and multiple connected units; a complete installed assembly may reach $3,000-$8,000 or more depending on span and finish work.
Glass upgrades affect the unit price. Low-E coatings, argon fill, laminated glass, tempered safety glass, and noise-control options can add roughly $50-$300 per window, with specialty glass potentially costing more. In cold climates, compare the quoted U-factor and glass package; in hot, sunny areas, compare solar heat gain ratings. A more expensive package is not automatically a better value if it does not address the home’s exposure or local climate.
The installation approach can shift the quote by hundreds of dollars per opening. An insert replacement uses the existing frame when it is sound, while full-frame work removes more material and exposes the rough opening. Full-frame installation is more appropriate when frames are damaged, but can add about $200-$800 per window for labor, trim, and related work. Rot or water intrusion may add further repairs after the old unit is removed.
Specify the opening size, window style, glass package, and installation method before comparing bids. A quote for a small insert double-hung window should not be compared directly with a full-frame casement that includes premium glass and new trim.
What labor time and crew rates mean for installation cost
A contractor may charge by the opening, by the project, or through a labor allowance. A straightforward insert replacement often takes about 2-4 labor hours per window for a small crew, while a full-frame job can take 4-8 hours per opening when trim removal, flashing, and finishing are included. These are work-hour estimates, not necessarily the total elapsed time at the home.
Typical residential window installation labor rates work out to approximately $75-$125 per worker-hour, though quotes often include travel, supervision, insurance, and overhead rather than displaying an hourly rate. Crews may also apply a minimum charge for small jobs. Replacing one or two windows can therefore cost more per unit than replacing eight or ten at the same home.
Ask whether the installation price covers interior casing and exterior trim. Some bids include basic trim work but exclude painting, siding repairs, or custom carpentry. Those exclusions can add $100-$600 per opening, depending on the materials and finish standard. A written scope helps prevent a low initial quote from growing after work begins.
Use the same installation scope when comparing Infinity with an Integrity replacement. A lower bid may reflect insert installation, while the higher bid may include full-frame removal, insulation, flashing, and new trim.
How much do regional labor rates change Marvin window prices?
Installation rates and product delivery costs vary by market. A project in a high-cost coastal city may run about 10%-25% above a typical national planning estimate, while some rural markets may come in 5%-15% below it. These are broad comparisons: local contractor availability, travel distance, housing style, and demand can outweigh the region itself.
In areas with older housing, historic-district rules or unusual opening sizes can increase labor and material charges. Urban projects may also involve limited parking, upper-floor access, or narrow work areas. Rural jobs may include a trip charge or higher delivery cost when the installer travels a long distance or handles a small order.
Climate can influence the selected glass and frame options, but it does not set a fixed regional price. A cold-weather glass package or impact-resistant glass in a storm-prone area may add cost regardless of the base window price. Request options with the same specifications from each bidder so regional labor differences are not confused with different products.
Use local written bids as the final price check. For a 10-window project, even a 10% regional difference can change the total by roughly $1,000-$2,200 at the installed price range shown above.
Three realistic quotes for different window projects
These examples illustrate how size and scope affect a quote. They are not fixed Marvin list prices; product availability and local installation rates determine the final amount. The labor-hour figures are approximate crew effort per opening and may be adjusted for travel or minimum charges.
| Project | Product and scope | Estimated labor | Estimated total |
|---|---|---|---|
| Four standard replacements | Four 3-by-5-foot double-hung units at $850 each, insert installation | 2-3 hours per opening at $75-$125 per hour | $4,600-$6,000, or $1,150-$1,500 each |
| Eight mixed-size replacements | Six standard units and two larger casements, removal and basic trim | 3-5 hours per opening at $75-$125 per hour | $10,500-$15,500, or about $1,310-$1,940 each |
| One large picture window | Custom unit around 5 by 6 feet, full-frame work and exterior finishing | 6-10 hours at $75-$125 per hour | $2,500-$4,500 for the opening |
The first example assumes sound existing frames and ordinary access. The second allows for a mix of product prices and more involved finishing. The large picture-window example includes a wider range because a custom unit, handling needs, and rough-opening repairs can materially change the cost.
For a larger order, request both a per-window rate and a project total. The per-unit figure makes product comparisons easier, while the total reveals delivery, setup, disposal, and crew minimums that may not scale evenly with the number of windows.
When an Integrity replacement needs more than a matching unit
Because Integrity is an older product label, a replacement may require identifying the original series, dimensions, glass, and frame construction before a contractor can price it accurately. A matching sash or component may be available for some existing units, but a complete replacement may involve a current Marvin product or a different configuration. Availability should be confirmed before budgeting around a presumed one-for-one match.
Repair can cost less when the frame remains sound. Replacing hardware, weatherstripping, or a sash may range from about $100-$500 per window, depending on parts and labor. Glass replacement can cost roughly $200-$700 per unit, with specialty or oversized panes costing more. If frames have widespread rot, failed seals across multiple units, or poor operation, repairs may be temporary rather than economical.
When comparing an Infinity quote with a replacement for an older Integrity unit, check the frame material, interior finish, exterior color, glass performance, and warranty terms. The current product may differ in construction or available options. Matching the old window’s appearance can require custom colors, grilles, or trim that increase the price.
Start with the condition and model of the existing window, not the brand name alone. A repair quote and a replacement quote answer different questions, and a low-cost repair does not include the performance or warranty of a new unit.
How to lower the Infinity or Integrity project estimate
Keep the scope consistent and avoid paying for options that do not solve a specific need. Standard sizes, common colors, and straightforward styles generally cost less than custom shapes, unusual finishes, or extensive grille patterns. If the existing frame is in good condition, ask whether insert installation is appropriate; if the frame is damaged, compare the added cost of full-frame work against the risk of leaving the problem in place.
Group several windows into one project when practical. Combining openings can spread delivery, setup, and disposal charges across more units, although the savings depend on the contractor’s minimums and the home’s layout. If work is not urgent, ask whether a flexible schedule or a less busy installation period changes the labor quote. Do not delay repairs when water is entering or the opening is deteriorating.
Get at least three itemized bids using the same window dimensions, glass package, and installation scope. Ask contractors to separate product, labor, removal, trim, repairs, and permit charges. A quote that is unusually low may omit flashing, finishing, disposal, or repairs that another bidder has included.
The most reliable savings come from controlling scope and comparing equivalent specifications. Keep a contingency of about 10%-15% for concealed rot or opening repairs, particularly when older windows have leaked or the surrounding trim is damaged.
