Updated September 24, 2026. Every Andersen and Renewal by Andersen statement below comes from the company’s own pages, checked on that date. How we research this
A Renewal by Andersen proposal is hard to judge because it is not a price for windows. It is one number for several things bundled together: a custom-made Fibrex composite window, measuring and manufacturing to your exact openings, installation by Renewal’s own crews, and a warranty and service package, usually presented through an in-home consultation that can include discounts and a financing offer. You cannot tell whether that number is reasonable until you separate those pieces and restate the total per opening, on the same scope as any other quote you have.
This page is a decoder, not a verdict. It does not rate Renewal by Andersen, and it does not give a national “fair price” per window: we have not found a published benchmark we would stand behind. It shows what to look for on your proposal, what to ask when a line is missing, and how to turn the total into a number you can compare.
What you are actually paying for
- The window. Renewal by Andersen’s Acclaim replacement windows are made of Fibrex composite. Andersen says they are not sold in standard sizes, and that they come with more color options, a wood interior option and more selections than its 100 Series.
- Custom fit. Andersen says each Acclaim window is made to fit the existing opening, with sizing customizable to 1/16 inch. Renewal describes a project technician measuring the windows and framing before the custom order is placed.
- Installation. Renewal says professional installation is included in the price, so one company is accountable for both product and installation. What the installation includes (method, trim, disposal, permits) still has to be read from your proposal.
- Warranty and service. Renewal’s corporate site lists 20 years on standard glass and Fibrex material (10 years on glass for coastal products), 10 years on locks, hinges and other components, and 2 years on professional installation, transferable to a later owner. Some local Renewal locations describe their installation coverage differently on their own sites, so the written warranty delivered with your proposal is the one that counts.
- Sales and payment terms. Renewal starts with a design consultation in your home or virtually, and says financing options vary by location and can include payment plans and promotional offers.
Each of these can be worth paying for. None of them usually appears as its own price on the proposal. That is what the decoder below is for.
Fibrex is the material, not the reason for the price
Fibrex is Andersen’s own composite of wood fiber and thermoplastic polymer. Andersen uses it for its 100 Series windows and patio doors, which are sold through dealers and installed by contractors, and for Renewal by Andersen’s products. Andersen describes Renewal as the side of its business that sells replacement products and services directly to homeowners.
Sharing a material does not make two windows the same product. Andersen answers the question directly on its Fibrex page: Renewal costs more than the 100 Series because of more than material. Renewal provides a service with the product, and builds it to fit your existing openings. Andersen also says the 100 Series can be a good replacement choice, especially in stucco homes and in projects that change a window’s shape or size.
So two common shortcuts are both incomplete. “It’s just Fibrex, so buy the 100 Series for less” ignores that a 100 Series quote from a local installer is a different purchase: different sizing, different options, a different installer and a different labor warranty. “It’s Fibrex, so the price is justified” ignores that the material is shared with a line Andersen prices “competitively to vinyl.” The useful question is narrower: what does this proposal include, per opening, that another quote does not? For the material and the 100 Series itself, see our Andersen 100 Series review and Andersen 100 vs 400. This page does not compare the two lines head to head.
How to decode a Renewal by Andersen proposal
Go through your proposal with this table. For each line, find the item in writing. Where it is missing, ask the question in the last column before you judge the price. Swipe sideways on a phone to see every column.
| Proposal line | What to find in writing | Why it moves the total | Ask if it is missing |
|---|---|---|---|
| Window / product | Product line, window type for each opening (double-hung, casement, picture, sliding, bay or bow), size or opening ID, and the count of openings vs. the count of units | Specialty shapes, bays and bows, and changing a window’s operating type cost more than like-for-like units. A bay can be several units in one opening | “Can I have a schedule that lists type, size and options for each opening?” |
| Glass and options | Glass package name plus the NFRC U-factor and SHGC; grilles; interior and exterior color; wood interior; hardware finish; screens | Options are priced per unit and add up. Glass package names do not compare across companies; NFRC numbers do | “Which of these are upgrades from the base window, and what does each one add?” |
| Opening condition | Notes on rot, out-of-square frames, stucco or brick, upper-floor access, and whether repairs are priced or left open | Damage found after the old window comes out is a common source of change orders | “What happens to the price if rot is found? Is the repair rate in writing?” |
| Installation method | Insert (new window set into the existing frame) or full-frame (old frame removed), stated for each opening | Full-frame is more work and changes the trim scope; insert keeps more of the old frame and can reduce glass area. See insert vs. full-frame | “Is each opening insert or full-frame, and why?” |
| Interior and exterior trim | Interior casing and stops, exterior trim or capping, sills, sealing, and who paints or stains | Trim can be included, excluded, or left for you to finish, and that changes what the total covers | “What will I see inside and outside the day the crew leaves? Who does the painting?” |
| Disposal and cleanup | Removal and haul-away of the old units and job-site cleanup | Usually a small line, but it should be named, not assumed | “Is disposal of the old windows included?” |
| Permits and lead-safe work | Who pulls the permit. For a home built before 1978: the firm’s EPA lead-safe (RRP) certification and lead-safe work practices in the scope | Permit fees and lead-safe containment add time and cost. EPA says window replacement in pre-1978 housing is always covered by its RRP rule, regardless of size | “Who pulls the permit? For a pre-1978 house: is the firm RRP-certified, and is lead-safe work included?” |
| Warranty and service | The written warranty document: glass, Fibrex, components, installation term, transfer rules, how claims are handled | Installation coverage and single-company service are part of what you pay for, and you can only compare them if they are in writing. See our window warranty decoder | “Can I have the full limited warranty document that applies to this proposal?” |
| Discount and financing presentation | Starting price, each discount and its condition, the date the price expires, the cash price, and financing terms (APR, promotion type, fees, total of payments) | A large percentage off tells you about the starting number, not about value. Financing can change what you actually pay | “What is the cash price if I sign within 30 days? What is the total of payments if I finance?” |
| Effective per-opening cost | Your own calculation, below. Proposals rarely show it | It is the only number you can line up against another quote | Work it out yourself before any comparison |

Work out your effective per-opening cost
- Take patio and entry doors out into their own line. They are priced very differently from windows.
- Count a bay or bow as one opening, but note it next to the result; one bay can move the average.
- Drop optional items you are not going to buy, and add items you would have to pay someone else for, such as painting trim.
- If you would carry a financed balance, use the total of payments, not the cash price.
- Do the same arithmetic on every other quote, on the same openings.
One public example, for illustration only. In a homeowner discussion we logged as Real Quote #001, a Renewal by Andersen proposal of about $46,000 for 14 openings works out to about $3,290 per opening, against about $25,000 (about $1,790 per opening) for a Pella 250 Series quote on the same house. The homeowner did not state the location, neither quote stated the installation method, and the discussion is about four years old. It shows the size of gap homeowners report. It is not what Renewal charges today or where you live. More examples: real window quotes.
Discounts, “today-only” prices and financing
If your proposal shows a starting price followed by one or more discounts (a percentage off, a promotion, a condition such as deciding the same day), read it this way:
- A percentage off is a percentage of the seller’s own starting number. It is not a comparison with the market, and it does not tell you whether the result is high or low for your scope.
- List every discount with its condition. Sign today, finance with the seller, minimum number of windows, a promotion end date. Ask which ones still apply if you take a week.
- Get the price in writing with a validity date. A price available only until the presenter leaves cannot be checked against anything else.
- Know your cancellation right. Under the FTC’s Cooling-Off Rule, most sales made in your home for $25 or more can be canceled until midnight of the third business day after the sale, and the seller must tell you about that right and give you cancellation forms. There are exceptions, and some states add their own rules; the cancellation notice in your contract is the starting point.
- Read the financing as its own offer. Renewal says its financing options vary by location. Ask for the APR after any promotional period, whether a promotion is deferred interest (charged back if a balance remains) or interest-free, any fees, the total of payments, and whether the cash price differs from the financed price.
How to compare a Renewal proposal with a dealer or local quote
The gap between a Renewal proposal and a local installer’s quote only means something when both describe the same job. Before comparing totals, line them up on:
- The same openings and window types, including bays, shape changes and operating-type changes.
- The same installation method for each opening.
- Glass compared by NFRC U-factor and SHGC, not by package name.
- The same interior trim, exterior capping and finishing, including who paints.
- Disposal, permits and, for pre-1978 homes, lead-safe work in both.
- Installation and labor warranty terms in writing from both.
- The price you would actually pay under each, with the same payment method.
Whatever difference remains after that is what you would be paying extra for: custom sizing, one company accountable for product and installation, the written warranty terms, and the color and interior options. Whether that is worth it depends on your house and your priorities, not on a national average.

Before you sign: a pre-signing checklist
- I have a per-opening schedule: type, size and options for each opening.
- I know which openings are insert and which are full-frame.
- The glass is described with NFRC U-factor and SHGC, not only a package name.
- Trim, capping, sills, sealing, disposal and who paints are written into the scope.
- I know what happens, and at what rate, if rot or framing damage is found.
- I know who pulls the permit. If the house was built before 1978, the firm is RRP-certified and lead-safe work is in the scope.
- I have the written warranty document, including the installation term and transfer rules.
- I have the cash price in writing, with the date it is valid until, and I know which discounts depend on deciding today.
- If financing: I have the APR, the promotion type, any fees and the total of payments.
- I have divided the price I would actually pay by the number of openings.
- I have at least one other quote on equivalent scope, or I know why I do not need one.
- I know my cancellation deadline and have the cancellation form.

How we researched this
On September 24, 2026 we reread Andersen’s Fibrex composite material page, including its answer on why Renewal by Andersen is priced differently from the 100 Series; Renewal by Andersen’s corporate articles on its warranty coverage and on what its price includes; the EPA’s Renovation, Repair and Painting page for contractors; and the FTC’s consumer page on the Cooling-Off Rule. The one price example is a public homeowner discussion we paraphrase in Real Quote #001, with its limits stated there. We did not test products, survey customers or obtain pricing from Renewal by Andersen, and we do not publish a national average price for Renewal windows. Warranty terms are from Renewal’s corporate site; local locations may describe coverage differently, and the document delivered with your proposal governs. Full methodology · editorial policy.

FAQ
Is Renewal by Andersen the same window as the Andersen 100 Series?
No. Both are made with Andersen’s Fibrex composite, but Andersen says Renewal’s Acclaim windows are custom-made to fit existing openings, offer more color and interior options, and are sold with Renewal’s installation and service. Same material, different product and different purchase.
Why is my Renewal by Andersen quote so high?
The total bundles a custom-made window, measuring, the installation scope, the warranty and service terms and often a financing offer into one number. Decode those lines and divide what you would actually pay by the number of openings before judging it against another quote.
What does the Renewal by Andersen warranty cover?
Renewal’s corporate site lists 20 years on standard glass and Fibrex material (10 years on glass for coastal products), 10 years on locks, hinges and other components, and 2 years on professional installation, transferable to a later owner. Ask for the written warranty document with your proposal, because some local locations describe installation coverage differently.
Can I cancel a window contract I signed at home?
Under the FTC Cooling-Off Rule, most sales made in your home for $25 or more can be canceled until midnight of the third business day after the sale. There are exceptions and state rules can add protection; start with the cancellation notice in your contract. This is not legal advice.
What is a fair price per window for Renewal by Andersen?
We do not publish one, because we have not found a national benchmark reliable enough. Public homeowner examples vary widely by location, scope and date. Divide your own proposal by the number of openings and compare it with a quote of equivalent scope.
