Andersen Window Cost Calculator

Andersen windows are quoted per window installed, which bundles the window unit and the labor to install it. Expect roughly $500 to $1,800+ per window depending mostly on the series: the 100 Series (Fibrex) runs about $400–$800 installed, the 200/400 Series about $600–$1,200, the A-Series about $1,000–$1,800, and the custom E-Series $1,400–$2,500+. Labor alone is typically $150–$400 per window and is already folded into those figures. Installing several windows at once lowers the per-window labor because the crew is set up once, so a 10-window project is more efficient than replacing one. Enter your window count and series in the calculator to anchor the estimate.

They're Andersen's product lines, ordered roughly by price and customization. The 100 Series is made of Fibrex (a wood-fiber/polymer composite) — the value line, strong and low-maintenance with limited colors. The 200 Series is a more basic wood/vinyl-clad line at a moderate price. The 400 Series is Andersen's best-seller — wood with vinyl-clad exterior, the classic 'Andersen window' balance of quality and options. The A-Series (Architectural) adds design authenticity, more performance options, and a Fibrex/wood/aluminum build for specific home styles. The E-Series (custom) is the premium, fully customizable line — wood interior with aluminum cladding and nearly unlimited sizes, shapes, and colors. The series is the single biggest cost driver, so pick the lowest line that meets your look and performance needs.

Andersen is a premium, widely trusted brand, and for homeowners staying put who value reputation, durability, energy efficiency, and strong warranties, the premium is usually justified — the windows are well-built, the Fibrex and wood/clad constructions hold up, and the brand name supports resale appeal. That said, Pella and Marvin compete closely at similar quality and price tiers, so it's worth getting quotes from more than one. If you're on a tight budget or outfitting a rental or flip, a value brand can make more sense than any premium line. The honest framing: Andersen is a safe, high-quality choice, not the only good one — compare comparable series across brands before deciding.

Insert (or 'pocket') replacement drops a new window into your existing, sound frame — keeping the trim and surrounding wall intact. It's faster, less invasive, and cheaper, and it's the right call when the existing frame is solid, square, and rot-free. Full-frame (new-construction) tears the old window out to the rough opening — frame, trim, and all — and rebuilds with new flashing and trim. It costs about 20% more here, but it's necessary when the frame is rotted, water-damaged, or out of square, when you're changing the window size or style, or in new construction. The calculator's Installation Type selector applies the full-frame premium. A good installer inspects your frames and tells you which you actually need.

Double-hung (two sliding sashes, usually tilt-in for cleaning) is the classic, most popular choice and the baseline price. Sliding/gliding is similar in cost and good for wide openings. Casement (crank-out, side-hinged) and awning (top-hinged) seal tightly and ventilate well, costing a bit more. Bay and bow windows cost dramatically more — often 50%+ — because they aren't a single window: they're a multi-unit assembly that projects out from the house, requiring several windows, a head and seat board, structural support, and far more installation labor and trim. The calculator prices double-hung, sliding, casement/awning, and bay/bow accordingly. Choose by ventilation, looks, and budget.

The per-window figures here are installed prices: the Andersen unit plus the labor to set it. Commonly billed as separate line items are removing and hauling the old windows, exterior capping/trim (the weatherproof outside finish), interior trim/casing (the inside finish), glass and grille upgrades, and oversized or specialty units — all of which this calculator offers as add-ons. Watch for hidden costs too: rotted sills or frames discovered during removal mean repair charges, and upper-floor or hard-to-reach windows raise labor. When comparing quotes, confirm exactly what's included — window, install, old-window disposal, both trims, and cleanup — so you're comparing apples to apples.

Andersen offers ENERGY STAR–qualified options across its lines, with Low-E glass coatings, dual-pane (and triple-pane on some series) insulated glass with argon fill, and frame materials (Fibrex, wood/clad) that resist conducting heat better than bare aluminum. The right glass depends on your climate: Andersen's high-performance Low-E4 and SmartSun packages are tuned for different regions, so check the NFRC label's U-factor (lower insulates better) and Solar Heat Gain Coefficient (chosen for your climate), and look for ENERGY STAR certification for your zone. The calculator includes a high-performance Low-E glass upgrade, since the glass package affects both cost and the energy savings you'll see over the windows' life.

The install itself is quick: a crew can set a standard replacement window in about 30–60 minutes once they're rolling, so most homes (5–15 windows) finish in 1 to 3 days. Full-frame installs, bay/bow units, upper floors, old-window removal, and trim work add time. The bigger scheduling factor is lead time — Andersen windows, especially custom A-Series and E-Series, are made to order and can take several weeks from order to delivery before installation can even be scheduled. So plan the timeline in two parts: weeks of manufacturing lead time, then a few days of installation. Your dealer can give firm dates once the order is specced.

All three paths exist and the trade-offs matter. Independent Andersen dealers and certified installers typically carry the full range (including A-Series and E-Series), do precise measuring, and stand behind the installation — best for custom or whole-home projects. Home-center programs (e.g., big-box) often focus on the 100 and 400 Series with their own install crews — convenient and competitive for standard replacements. Hiring a window installer who orders Andersen gives you installer accountability plus brand quality. Whichever route, confirm the installer is experienced with Andersen, that the measure is done by whoever's responsible for fit, and that the labor warranty is in writing alongside Andersen's product warranty.

Andersen backs its windows with limited warranties that vary by series (generally covering glass, components, and the unit for set periods), and many are transferable to a subsequent homeowner — a resale plus. Two things protect your coverage: professional installation to the manufacturer's specs (improper install can void claims), and registering the product after installation. Keep your order paperwork, the series and glass package details, and the installer's separate labor warranty together. When you hire, ask the installer to confirm both warranties in writing and to handle or walk you through registration. The calculator estimates your project cost; the warranty is part of what you're paying the premium for.
