How much do Andersen windows cost?
Andersen sells the same frame material through three very different channels. The channel moves the price more than the window does.

What Andersen windows cost, by series
Andersen does not sell one window. It sells four families of them, and the price difference between the cheapest and the most expensive is roughly ten to one once installation is included.
The 100 Series is the volume product: a Fibrex composite frame sold through dealers and big-box stores, intended to compete with premium vinyl. The 400 Series is the classic Andersen wood window with a clad exterior, sold through a dealer network that measures and installs.
Renewal by Andersen is a separate business: full-service, no subcontracted installation, and the highest price in the lineup. The window is Andersen’s; the service model is what you are paying the difference for.
Installed cost per window, 2026 national ranges
| Series | Installed cost | What it is |
|---|---|---|
| 100 Series | $400 – $1,500 | Fibrex composite frame, double-hung and casement, stock sizes |
| 200 Series | $450 – $2,000 | Wood-core frame with a clad exterior, sold through dealers and retail |
| 400 Series | $1,500 – $2,500 typical | Solid wood interior, vinyl-clad exterior, the classic Andersen |
| A-Series | $2,000 – $3,500 | Designer line: custom sizes, colours and divided light patterns |
| Renewal by Andersen | $1,500 – $5,000 | Full-service measurement, installation and warranty in one contract |
The same 400 Series window has been quoted between $500 and $3,000 depending on region, dealer and job size. Treat any single figure as a starting point, not a price.
Why the same window has three prices
Andersen sells through a dealer network, through large retailers, and through Renewal. Those three channels carry different overheads, and that overhead is most of the difference between a $700 quote and a $2,000 quote for a window that came out of the same factory.
A dealer quote includes measuring, ordering, delivery, installation labour, trim and a warranty on the installation. A retailer sale often stops at the unit: you are buying a box and arranging your own installer, whose labour is not in the sticker price.
This is why comparing an Andersen price from a retailer with a Renewal quote is meaningless. Compare installed to installed, with the same scope.
What each channel actually includes
| Channel | Price includes | You organise |
|---|---|---|
| Big-box retail | The unit, delivery to store | Measurement, installer, trim, flashing, permit, disposal |
| Independent dealer | Measurement, unit, installation, basic trim | Upgrades, painting, any structural work |
| Renewal by Andersen | Measurement, unit, installation, trim, clean-up, one warranty | Nothing — that is what you are paying for |
A retail unit plus a good independent installer is often the cheapest route, provided the installer measures before you order.
- Fibrex is a wood-fibre and polymer composite: it does not rot, holds paint well and expands less than vinyl.
- The 400 Series is real wood on the inside, clad on the outside — warmer to the touch, and it needs no exterior painting.
- Stock sizes cost far less than custom. Two custom openings in an otherwise stock order can add several hundred dollars.
- Installation quality varies more between installers than between series. A well-installed 100 Series outperforms a badly installed 400.
- Ask what the warranty covers: the unit, the glass, the labour and the installation are four different things.
A worked example: ten 100 Series double-hungs
A 1980s colonial with ten identical openings on two floors. The homeowner keeps stock sizes to avoid custom pricing, and the house was built after 1978 so no lead-safe work is needed.

Remove the lead-safe line if the house is post-1978 and the same job is $11,050. For comparison, the same ten openings through Renewal would commonly land between $15,000 and $35,000.
Is the 400 Series worth double the 100 Series?
On performance, not much. Both meet the same energy ratings when specified with comparable glass, both are warranty-backed, and both will outlive a cheap vinyl window.
On feel and longevity, yes — for some houses. The 400 Series has a wood interior that takes stain and paint, a profile that suits older homes, and a clad exterior that never needs painting. In a 1920s house with original trim, the 100 Series looks like a replacement window; the 400 does not.
The honest rule: buy the 100 Series when the interior finish is painted drywall and nobody will notice. Buy the 400 when the interior woodwork is visible and part of the house.
Choosing between the two workhorse series
| 100 Series | 400 Series | |
|---|---|---|
| Frame | Fibrex composite | Wood core, vinyl-clad exterior |
| Interior finish | Composite, paintable | Real wood, stain or paint |
| Typical installed price | $400 – $1,500 | $1,500 – $2,500 |
| Best in | Post-1980 houses, painted trim | Older homes, visible woodwork |
| Maintenance | Wipe clean | None outside, occasional inside |
Both are sold in stock and custom sizes; the custom premium is similar across the two series.
Where the money is actually lost
The expensive mistakes on an Andersen job are rarely about the series. They are about measurement, ordering and installation — the three steps where a cheap job becomes a second job.
Order windows before the installer has measured each opening and one wrong unit becomes a six-week reorder. Accept a quote that does not mention flashing and the leak appears two winters later, after the warranty conversation has moved to the installation contract.
- Have the installer measure, not the salesperson — and measure each opening, not one of each size.
- Confirm whether the price is installed or unit-only. It is the single most common source of confusion.
- Insist on head flashing and sill pans in writing. They are cheap now and expensive later.
- Check who honours the labour warranty if the installer goes out of business.
- Ask for the NFRC label values for the exact glass package quoted, not the series brochure.
How long an Andersen replacement takes
Same shape as any window job: measurement, manufacturing, installation.
Measure and order
1 – 3 days
Every opening measured; stock sizes confirmed against the schedule.
Manufacturing
4 – 10 weeks
Stock sizes ship faster; custom colours and grids run longer.
Installation
1 – 3 days
Ten openings is typically two days for a two-person crew.
Trim, seal and clean-up
1 – 2 days
Casing, insulation, caulk, interior touch-up.
Renewal jobs follow a longer sales process but a similar installation window once the contract is signed.
The six most expensive Andersen mistakes
None of these are about picking the wrong series. All of them are about the contract.
Comparing a retail unit price to an installed quote
One includes labour, trim and flashing; the other does not. Put both on an installed basis before deciding.
Assuming Renewal sells a better window
Renewal sells a better service — measurement, installation and one warranty. If you already have a trusted installer, you are paying for something you will not use.
Ordering from stock sizes without checking the openings
A stock window that does not fit the rough opening needs a filler and new trim. Measure first, then choose the series.
Skipping the flashing line
Water gets in above the window, not through it. Head flashing is the difference between a dry wall and a repair.
Buying the 400 Series for a house where it is invisible
Wood interiors cost real money and are hidden behind painted drywall in most modern rooms.
Not confirming the glass package
The series price assumes a standard glass. Low-E, laminated or triple glazing change both the price and the lead time.
Before you sign an Andersen quote
Ask these six questions of every channel you compare.
- Is this price installed, or unit only?
- Which series and which glass package exactly?
- Who measures, and are all openings measured?
- Is head flashing and sill panning included?
- Who honours the labour warranty, and for how long?
- Is the permit pulled by the contractor?
- What is the lead time in weeks, in writing?
- What is the payment schedule, and what is held back for the punch list?

Frequently asked questions
How much do Andersen windows cost installed?
The 100 Series runs about $400 to $1,500 per window installed, the 200 Series $450 to $2,000, and the 400 Series typically $1,500 to $2,500. Renewal by Andersen, which includes full-service installation, ranges from $1,500 to $5,000 per window.
Is Renewal by Andersen the same as Andersen?
Renewal by Andersen is a subsidiary that sells and installs Andersen windows as a full-service contractor. The windows come from the same manufacturer, but the pricing, the sales process and the installation warranty are Renewal’s, and the price per window is substantially higher.
Are Andersen 100 Series windows any good?
Yes. The Fibrex frame is more stable than vinyl in heat and cold, does not rot, and holds paint well. It is the value option in the Andersen range and performs comparably to premium vinyl when it is installed correctly.
Where can I buy Andersen windows?
Through independent Andersen dealers, through large retailers for stock sizes, and through Renewal by Andersen for full-service installation. The unit is the same product family; what changes is measurement, installation, warranty and price.
Do Andersen windows come with installation?
Only through a dealer or Renewal. A retail purchase is usually the unit alone, and you arrange the installer. Confirm in writing what the price includes before comparing quotes from different channels.
What warranty does Andersen offer?
Andersen warrants the unit and the glass for a defined period, and the 400 Series glass carries a longer coverage than the entry series. The installation itself is warranted by whoever installs it, which is why the installer’s reputation matters as much as the brand.
