Andersen Narroline conversion kit prices typically range from $250 to $700 per window for compatible replacement components, before professional installation. A complete installed conversion commonly totals $450-$1,200 per window, depending on kit availability, window size, labor, and whether the existing frame needs repairs.
These are planning ranges, not a fixed Andersen price list: Narroline is a legacy window line, and parts and compatibility can vary by model and age. The final quote depends especially on what the kit includes and how many windows are being converted.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Conversion components per window | $250 | $450 | $700 | Compatible sash, balances, and related parts; package contents vary |
| Installation labor per window | $200 | $400 | $650 | More for difficult access or frame adjustments |
| Installed conversion per window | $450 | $850 | $1,200 | Assumes the original frame remains serviceable |
| Four-window project | $1,800 | $3,400 | $4,800 | Before major carpentry or replacement-frame work |
Assumptions: U.S. contractor pricing, ordinary access, compatible parts, and no extensive rot repair. Confirm kit contents and fit before ordering.
What a Narroline conversion usually costs per window
For a standard, accessible window, budget about $450-$1,200 installed, with parts and labor priced separately. The lower end generally assumes a straightforward opening, readily available compatible components, and a local installer charging moderate labor rates. A typical planning figure is about $850 per window.
The word “conversion” can describe different scopes. One quote may cover replacement sash and balance components that reuse the existing frame; another may include liners, hardware, trim adjustments, or repair work. The price therefore depends on the exact kit and the condition of the opening, not just the Narroline name.
For an owner ordering parts only, $250-$700 per window is a reasonable budget range to investigate, not a guarantee of current stock or a manufacturer-set price. Legacy parts may be sourced through specialty dealers, window-service companies, or salvage channels. A dealer may need the window identification details to verify the correct configuration.
Measure and identify each window before comparing prices. Sizes, glazing, sash configuration, and production details can affect fit. Assumptions: one double-hung opening, existing frame retained, standard parts, and no structural repair.
How sash, balance, and installation charges form the quote
The parts list and labor scope matter more than a single “kit” price. Ask the seller or installer to itemize the package: two sashes may not be included, and balance or liner components may be priced separately. The table shows common planning ranges for one window; actual package contents differ.
| Quote component | Low | Average | High | What changes the price |
|---|---|---|---|---|
| Sash and glazing components | $150 | $300 | $500 | Quantity, size, glass type, and availability |
| Balances, liners, and hardware | $75 | $150 | $275 | Included parts, compatibility, and replacement scope |
| Installer labor | $200 | $400 | $650 | Access, adjustment, and local hourly rates |
| Delivery and disposal | $0 | $40 | $125 | Shipping method and old-part removal |
| Minor frame or trim work | $0 | $100 | $350 | Localized patching, sealing, or trim adjustment |
These figures are line-item estimates and should not be added mechanically if a contractor gives a bundled price. Some quotes include delivery or disposal; others charge separately. Sales tax may also apply to parts, depending on the state and how the job is billed.
For labor estimates, a simple planning formula is . An installer might spend roughly 2-4 hours on a routine conversion, with hourly rates around $75-$125. Difficult removal, fit adjustments, or repair can increase the time.
Which Narroline sizes and frame conditions raise the price?
Large openings, scarce configurations, and damaged frames are the most common reasons a quote rises. A small or standard-size window with easily sourced parts may stay near the lower range. A wider or taller sash can cost more because the parts are larger, heavier, or less readily available.
Ask the supplier to confirm compatibility using the window’s identification information, measurements, and photographs. A difference of even a few inches can affect the sash or balance selection. If multiple windows have different sizes, each opening may require its own parts specification rather than a single uniform kit.
Frame condition is another major variable. A conversion that reuses sound jambs and the original frame is usually less expensive than one requiring rot repair or extensive carpentry. Localized repairs may add $100-$350 per opening; deeper water damage or structural work can exceed that range and may make replacement more practical.
Glass options also affect the estimate. Basic replacement glass may cost less than insulated, tempered, or specialty glazing, when a matching option is available. Before paying for a kit, confirm which glass and hardware are included, whether the sash is pre-glazed, and whether the warranty covers parts only or installation as well.
How much does a window contractor charge to install it?
Professional installation often adds $200-$650 per window, with ordinary conversions commonly taking 2-4 hours. A contractor may charge by the opening, by the hour, or as part of a multi-window project. The per-window price can fall when several similar windows are completed in one visit, since travel and setup time are shared.
Labor is higher when the installer must work above ground level, remove stubborn components, adjust the opening, or protect delicate interior finishes. First-floor windows with clear access are generally simpler than upper-floor openings or windows obstructed by furniture, landscaping, or exterior trim.
Request a written scope that states who supplies the kit, what gets removed, whether old parts are hauled away, and what happens if the frame is damaged. A low labor quote may exclude prep, sealing, trim repair, or return visits for parts that do not fit.
For several windows, ask for both a per-opening rate and a total project price. Confirm whether the contractor has experience with Narroline units and will check dimensions before installation. A specialist may charge more per hour but reduce the risk of ordering incompatible parts or damaging reusable components.
When does a Narroline repair cost less than conversion?
A repair can be the lower-cost choice when the frame and sash remain sound and only one part has failed. A balance or hardware repair may cost roughly $100-$350 per window, depending on access and parts availability. Glass replacement or sash work can cost more, particularly if a matching component is hard to source.
Conversion makes more sense to compare when several components are worn, the sash does not operate reliably, or the owner wants a broader update while retaining the existing frame. The total may still be below full-frame replacement, but the savings shrink if the frame needs substantial work or the necessary kit is unusually expensive.
Full-frame window replacement commonly runs about $800-$2,000 or more per opening installed, with size, material, glazing, and exterior work driving the range. This is a broad comparison, not a Narroline-specific quote. Replacement may include a new frame and a wider selection of current products, while a conversion generally depends on the old opening remaining suitable.
Have the contractor inspect the sill, jambs, and surrounding wall for water damage before choosing. If there is rot, persistent leakage, or a distorted frame, replacing only the moving parts may leave the underlying problem unresolved. Compare the written repair, conversion, and replacement scopes rather than judging by the headline price alone.
How Midwest, coastal, and major-city labor shifts estimates
Location can move installed pricing by roughly 10%-30% from a typical local baseline. Large metro areas and high-cost coastal markets often have higher labor rates and service minimums than smaller cities or rural areas. Freight for hard-to-find legacy components can also affect the total, especially when parts are shipped individually.
As a planning example, a straightforward $850 conversion in a moderate-cost market might land around $935-$1,105 in a higher-cost city, or about $680-$765 in a lower-cost rural market if local labor is less expensive. These percentage comparisons are illustrative; parts availability and contractor minimums can outweigh regional averages.
Distance matters too. A service company may charge a trip or diagnostic fee of about $75-$175, sometimes credited toward approved work. Rural customers may encounter higher travel charges, while urban customers may face parking, access, or scheduling fees.
Get quotes from providers who serve the same area and request the same scope from each. A regional price comparison is meaningful only when parts, removal, sealing, disposal, and warranty terms match. If the work is not urgent, combining multiple compatible windows in one visit may reduce the effective labor cost per opening.
Can ordering several kits or preparing openings reduce the bill?
Scope control and accurate measurements are the safest ways to limit avoidable charges. If several windows need the same type of work, ask whether the supplier offers a multi-unit price and whether the installer can complete them in one trip. Savings depend on the seller and availability; legacy parts are not always discounted in quantity.
Before ordering, label each opening and provide measurements, photos, and identification details to the parts supplier. Verify the return policy for special-order components. A kit that cannot be returned can erase any apparent savings if it is the wrong size or configuration.
Clear furniture and window coverings before the crew arrives, and ask whether the homeowner can remove screens or movable items safely. Avoid dismantling the sash or balance system unless the installer specifically requests it; improper removal can damage reusable parts or create a safety hazard.
Compare at least two itemized quotes, but check that each includes the same components and warranty. Avoid paying for unrelated upgrades unless they solve a documented issue. If the frame is sound, retaining it can control scope; if it is damaged, treating repair as optional may lead to additional costs later.
What should a Narroline conversion quote include?
A useful quote identifies the exact components, labor, exclusions, and warranty for each opening. It should state whether the price includes both sash sections, balance or liner hardware, glazing, delivery, installation, cleanup, and disposal. “Conversion kit included” alone is not detailed enough to compare offers.
Ask the contractor to note how compatibility was verified and what condition the existing frame must meet. The quote should explain the added charge if hidden rot or damaged jambs are discovered. It should also specify whether any adjustment or return visit is included if the installed sash does not operate correctly.
Check warranty terms carefully. Parts and labor may have separate coverage, and a used or discontinued component may carry different terms from a current product. A warranty with exclusions for installation by others may affect the real value of a parts-only purchase.
For budgeting, keep a contingency of about 10%-15% for minor repairs, shipping changes, or extra labor. A larger reserve may be appropriate when the window has visible water damage or the kit must be specially sourced. Assumptions: standard access and no major framing repairs; local terms and product availability can change the estimate.
