Simonton Windows Review: 5500, Cost and Warranty (2026)

Simonton makes vinyl windows and sells them two ways: through local dealers and contractors, and, for one collection, only through The Home Depot. Its warranty differs by line and by region, so the document attached to your quote matters more than the brand name on it.

What Simonton sells

Simonton belongs to Cornerstone Building Brands of Cary, North Carolina, which also owns Ply Gem, Atrium, Silver Line and American Craftsman. Fortune Brands sold the Simonton business in 2014, and funds managed by Clayton, Dubilier & Rice have owned Cornerstone outright since July 2022. The company itself is older: Fred and Sybil Simonton started it in 1946 in Pennsboro, West Virginia, as an awning maker called Penn Vent Awning, and it began making vinyl replacement windows in 1981, according to a 2016 Industry Today profile. That profile put its plants in West Virginia, Illinois and California. We couldn’t confirm the current list.

Simonton’s collections page lists many replacement lines, and the ones you’re offered depend on your region. The main ones:

The 5500, formerly sold as Reflections 5500, is the line Simonton documents in most detail. It has a beveled vinyl frame in every common style, with ProSolar low-E glass, argon and an Intercept spacer standard. Triple-pane, laminated sound and security glass and coastal impact glass are options, and Simonton says the 5500 double-hung carries the Good Housekeeping Seal.

Other current replacement names include the 6150, 6200, MaxView 7600 and 7800, ComfortSmart, HarborLight, 5050, Premium and Pro. Older names such as Impressions 9800, Asure and Verona still have warranty documents on Simonton’s site but aren’t on its collections page. Simonton also makes Window World’s S-series impact windows, according to a 2024 rebate from Cornerstone.

What Simonton windows cost

Nationally, our model puts an installed 3 x 5 ft vinyl double-hung at $700–$1,520, a vinyl casement at $840–$1,825 and an impact-rated window at $910–$2,430+. The cost calculator and your city page give local numbers.

Simonton publishes no prices. The one current third-party estimate we found is from Modernize, a lead-generation site, in August 2026:

Series	Modernize estimate, per window
5500 (Reflections)	$600 to $1,200 installed (another table on the page says $450 to $1,500)
DaylightMax	$600 to $1,200
Impressions 9800	$800 to $1,500
ProFinish	$400 to $900

The same page says installation adds $150 to $500 a window, so it isn’t clear that every figure includes it.

Home Depot doesn’t sell a Simonton double-hung off the shelf. On homedepot.com in October 2026, Simonton double-hungs appeared only as an installed product, priced after an in-home consultation. The Simonton windows sold supply-only were Premium WX new-construction sliders with a nailing fin: a 47.5 x 35.5 inch white slider with ProSolar Shade low-E glass was listed at $533, before installation. In practice, the itemized quote is the number to test.

How buying Simonton works

Through a dealer or contractor. Simonton sells to dealers, distributors and contractors, and runs a loyalty program for them called Simonton ProNetwork. The dealer measures, quotes and installs, and sets financing, discounts and lead times. Simonton publishes none of those.

Through The Home Depot. The 6000 collection is sold only there. Its window series are the 6100, the 6200 and the 6500, which Simonton calls its premier line. Home Depot arranges installation, and Simonton’s Home Depot site sends warranty questions to 1-800-HOMEDEPOT. Third-party reviews describe Home Depot’s installation warranty in conflicting terms, and we couldn’t open Home Depot’s own document, so get the labor term on the contract. Our Home Depot windows guide has more.

Simonton warranty

Simonton publishes separate warranties by line, region and purchase date. Two current ones show how far apart they can be:

Coverage	5500, 5050 and Inovo, East (bought from July 1, 2026)	DaylightMax and Madeira, West (from March 31, 2025)
Vinyl and hardware	Lifetime; stays lifetime after one transfer (“Double-Lifetime”)	Lifetime
Screens	Lifetime	1 year
Glass seal	Prorated: 100% for 20 years, 75% to year 50, 50% after	See the West document
Glass breakage	3 years, with double-strength glass only	Lifetime accidental breakage, in six western states only
Labor	“Labor costs are not included”	Included for products installed in WA, OR, CA, NV, AZ and HI
Transfer	Online form within 30 days of sale, with the order number from the frame’s bar code; no fee stated	Once, within 30 days

Under the eastern warranty, neither Simonton nor its distributors pay to remove or reinstall a window. A free replacement part can therefore come with a paid service call, unless your installer’s own warranty covers it. Laminated glass is covered for 20 years and exterior laminates or coatings for 10. Registration is encouraged but not required.

Other lines read differently again. The StormBreaker Plus impact warranty (November 2025) gives lifetime coverage on vinyl, hardware and screens, the same prorated glass-seal schedule as the 5500 and 20 years on laminated glass. Its summary lists no breakage coverage, and labor is excluded. ComfortSmart and HarborLight (July 2024) cover the original owner for life but a later owner for 20 years. Their glass seal is prorated from year 10, and breakage cover is an optional program that doesn’t transfer. For the Home Depot 6000 collection, Simonton’s site says only that it carries a lifetime limited warranty and sends questions to Home Depot.

MaxView and older lines have their own documents. Ask for the one that matches your line and purchase date, and compare it with other brands in our warranty comparison.

What to check in a Simonton quote

1. The series and its warranty document. Match both to your region and purchase date. The same brand can carry lifetime labor in Oregon and none in Ohio.
2. Who pays labor after the install. In the East, Simonton doesn’t. Get the installer’s workmanship warranty in writing.
3. The glass. ProSolar, ProSolar PLUS or triple-pane, with NFRC U-factor and SHGC for the exact unit. If you want the 3-year breakage coverage on the 5500, confirm double-strength glass.
4. At Home Depot, whether it’s the 6100 or the 6500, and the installation warranty’s labor term in writing.
5. Impact glass, if you need it: StormBreaker Plus or the 5500 with coastal impact glass, and the rating your local code requires (impact window costs).

What owners report

The Better Business Bureau files Simonton under its parent. Its Simonton Windows listing in Vacaville, California points to the headquarters profile of Cornerstone Building Brands, which covers Cornerstone’s 20-plus brands. On October 30, 2026 that profile was rated A+ and accredited (since May 2024), with 330 complaints in the last three years and 126 in the last 12 months. Those counts include every Cornerstone brand, so they say little about Simonton alone.

We found one court case over Simonton windows. In 2016, owners whose windows had fogged between the panes filed a proposed class action in federal court in Minnesota (Kiefer v. Simonton Building Products). Simonton had sent them free replacement glass units but wouldn’t pay to install them. In April 2017 the court dismissed the case: it found the warranty’s limits, including its repeated exclusion of labor, enforceable as written, and the fraud claims too vague to proceed. The owners appealed. In June 2018 the parties settled for what Simonton’s then-parent, Ply Gem, called a nominal amount.

This Old House’s October 2026 review reports three recurring complaints from Simonton owners: broken components, slow repairs and difficulty getting warranty claims honored.

How Simonton compares

Among dealer-sold vinyl, Alside pays one year of labor under its main warranty, and ProVia includes lifetime glass breakage on its upper lines. At a home center, compare the 6000 collection with the other brands in our Home Depot and Lowe’s guides. Run any quote through the quote checker to see where it falls in your city.

Frequently asked questions

›Are Simonton windows good?

We don't rate brands. What's documented: Simonton's lines are vinyl, the 5500 comes standard with low-E glass and argon gas, and Simonton says its 5500 double-hung carries the Good Housekeeping Seal. This Old House (2026) reports owner complaints about broken components, slow repairs and trouble getting warranty claims honored. Read the labor terms before you buy: Simonton's eastern replacement warranty says labor costs are not included.

›How much do Simonton windows cost?

Simonton doesn't publish prices; dealers and Home Depot set them. Modernize (August 2026) estimated the 5500 at $600 to $1,200 per window installed and DaylightMax at the same range, though its page also gives conflicting figures. Our national range for an installed vinyl window is $700–$1,520, and $840–$1,825 for a vinyl casement.

›Can you buy Simonton windows at Home Depot?

Yes. Simonton's 6000 collection, the 6100 and 6500 series, is sold only through The Home Depot, which arranges installation, and Simonton's Home Depot site sends warranty questions to 1-800-HOMEDEPOT. This Old House and Modernize also list Simonton among Home Depot's window brands. Simonton's other lines are sold through dealers and contractors.

›What is the Simonton 5500 series?

A vinyl replacement line formerly marketed as Reflections 5500, with a beveled frame. It comes as a double-hung, slider, casement, awning, picture, bay, bow, garden or shape window, with ProSolar low-E glass, argon and an Intercept spacer standard. Options include ProSolar PLUS, triple-pane glass, laminated sound or security glass and coastal impact glass.

›Who owns Simonton windows?

Cornerstone Building Brands of Cary, North Carolina, which lists Simonton among its window brands with Ply Gem, Atrium, Silver Line and others in its 2025 annual report. Funds managed by Clayton, Dubilier & Rice have owned Cornerstone outright since July 2022. Fortune Brands sold the Simonton business in 2014. The company began in 1946 in Pennsboro, West Virginia, as a family awning business, and started making vinyl replacement windows in 1981.

›Has Simonton been sued over its windows?

We found one case. In 2016 owners whose windows had fogged between the panes filed a proposed class action in federal court in Minnesota, Kiefer v. Simonton Building Products, because Simonton supplied free replacement glass but wouldn't pay to install it. The court dismissed it in 2017, finding the warranty's labor exclusion enforceable, and while the owners' appeal was pending the parties settled in 2018 for what Simonton's then-parent called a nominal amount.

›Does Simonton's warranty cover labor?

It depends on the line and where you live. The eastern warranty for the 5500, 5050 and Inovo (purchases from July 1, 2026) says labor costs are not included. The western warranty for DaylightMax and Madeira includes labor, but only for products installed in Washington, Oregon, California, Nevada, Arizona and Hawaii. At Home Depot, the installation warranty is Home Depot's, so get its labor term in writing.
