Andersen 100 Series single-hung windows typically cost $350-$800 per window before installation, or about $700-$1,500 installed. Final pricing depends on window size, glass and finish options, the number of windows, labor rates, and whether old units or trim need removal.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Window only | $350 | $575 | $800 | Standard sizes and configurations |
| Installed per window | $700 | $1,050 | $1,500 | Replacement in a typical opening |
| Eight-window project | $5,600 | $8,400 | $12,000 | Installed, before major repairs |
| Custom-size unit | $600 | $900 | $1,300 | Window only; size and options affect price |
What a 100 Series single-hung window costs installed
A standard replacement unit is commonly $350-$800 before labor. A straightforward installation often adds $350-$700 per opening, putting the combined price around $700-$1,500. A typical midrange quote for a standard-size unit with ordinary access is approximately $1,050 installed.
Prices assume an existing framed opening, standard color and glass, and no structural repairs. Custom dimensions, specialty glass, interior or exterior trim work, and higher-cost metro labor can increase the total. Assumptions: standard replacement scope, normal access, and no substantial water or framing damage.
For a basic replacement, budget about $700-$1,500 per window installed. Quotes may differ depending on whether they include disposal, flashing, insulation, finish work, and sales tax.
How the window, labor, and removal shape the quote
Window material and options are only part of the bill. Installation scope can change the labor charge substantially, especially when a contractor must remove interior casing or repair the opening. The following ranges are typical planning figures, not fixed Andersen list prices.
| Quote item | Typical range | Pricing basis | What it covers | Common cost trigger |
|---|---|---|---|---|
| Window unit | $350-$800 | Per window | Standard 100 Series configuration | Custom size or upgraded glass |
| Installation labor | $250-$550 | Per opening | Set, fasten, seal, and adjust | Limited access or finish work |
| Old window removal | $50-$150 | Per window | Removal and basic handling | Heavy or difficult-to-remove units |
| Disposal and materials | $40-$160 | Per opening | Haul-away, insulation, sealants | Local disposal fees or extra flashing |
| Opening repair | $100-$600+ | Per opening | Minor sill or frame repairs | Rot, water damage, or out-of-square framing |
A one-window replacement may take 2-4 labor hours, often billed as part of a per-window installation charge rather than an hourly invoice.
Removal, disposal, and opening repairs can add $90-$750 or more beyond the new unit and basic installation.
Why opening size and glass options change the price
Standard sizes generally cost less than units made to fit unusual rough openings. A window around 24 by 36 inches may sit near the lower end of the product range, while a unit around 36 by 60 inches can cost more because it uses more material and may require additional handling. Exact prices depend on the dealer’s available configurations.
Glass upgrades also affect the quote. Low-E coatings, enhanced energy packages, tempered glass, and obscure glass can add roughly $40-$200 or more per window, depending on the specification. Tempered glass is often required near doors, tubs, or low sill locations, so local code and the opening’s placement matter.
Confirm the rough opening and required glass before comparing bids. A quote for a standard-size unit is not directly comparable to one that includes custom sizing or safety glass.
How installation labor and location affect the total
Labor for an uncomplicated replacement commonly works out to $250-$550 per opening, with higher rates in expensive metropolitan areas. As a broad comparison, urban projects may run 10%-25% above national midrange pricing, while rural work can be 5%-15% lower when contractors are nearby and access is easy.
These differences are not guaranteed: travel distance, seasonal demand, minimum service charges, and crew availability can outweigh regional averages. Replacing several windows at one address may reduce the per-window charge because setup and travel costs are shared.
Get a project total as well as a per-window rate. Ask whether labor includes flashing, insulation, trim, cleanup, and final adjustment.
Three installed quotes for common replacement projects
A single standard opening illustrates the lower-scope case: a $475 window, about 3 labor hours valued at $125 per hour, and $100 for removal and supplies totals about $950.
For six standard windows, a contractor might quote $3,300 for units, $2,100 for installation labor, and $450 for disposal and supplies, totaling $5,850, or about $975 per opening.
A larger eight-window project with custom dimensions and some trim work could include $6,800 in units, $3,600 in labor, and $1,000 in removal and repairs, for a total near $11,400. These examples show how scope and options can move a project beyond the basic per-window estimate.
Removal, trim, and repairs that can raise the bill
Full-frame replacement costs more than a simple insert replacement because it may involve removing more of the existing frame and rebuilding or refinishing the opening. Interior casing replacement can add about $100-$300 per window, while exterior trim repairs commonly add $75-$250 per opening.
Hidden rot or water damage cannot always be priced accurately before the old window is removed. Contractors may quote a base installation price and a separate repair rate, often $75-$125 per labor hour plus materials, for work discovered during installation.
Have bids state how concealed damage will be approved and charged. This helps prevent unexpected work from being treated as included when it is not.
100 Series versus vinyl and higher-end window options
Basic vinyl replacement windows may cost roughly $250-$600 per unit before installation, often less than a 100 Series configuration. Higher-end composite, wood-clad, or custom windows can exceed $800-$1,500 for the unit alone. Product performance, appearance, glass package, and warranty terms vary, so the lowest purchase price may not offer the same specifications.
For an existing window that only has a failed balance, damaged lock, or minor seal issue, a repair may cost about $100-$400. Repair is less practical when the frame is deteriorated, the sash is badly damaged, or multiple components have failed.
Compare the installed scope and glass specifications, not just the unit price. A lower-cost substitute may be a reasonable choice if its size, performance, and finish meet the project needs.
Ways to lower the Andersen window replacement price
Replacing several windows at once can spread setup and travel costs across more openings. Keeping standard sizes, colors, and glass options can also avoid custom-order premiums. Homeowners can remove curtains and clear access before the crew arrives, but should leave window removal and structural work to the contracted installer unless the bid explicitly allows customer preparation.
Request at least three itemized quotes using the same window size, glass package, and installation scope. Check whether each price includes haul-away, trim, permits if required, and tax. Avoid paying for upgrades that do not address a specific need, and compare repair pricing when damage appears limited.
The clearest savings come from standard specifications and comparable, fully itemized bids. A low quote that excludes disposal or finish work may cost more after add-ons are included.
