Window Nation, step by step
Book a free consultation
A designer visits your home, measures every opening and shows styles, colors and glass options.
Get a quote and offer
You get a price in the home, usually with a current promotion. Ask for an itemized written quote and take it with you to compare.
Custom build
Windows are made to your measurements by the company's manufacturing partners, which takes several weeks.
Installation
A crew led by a factory-trained installer removes old windows and installs the new ones, in 1 day for most homes, according to the company.
Service and warranty
For problems, submit a service request with the manufacturer name and serial number; Window Nation says a representative responds within 48 business hours.
Window Nation legitimacy and licensing
Yes. Window Nation opened its first showroom in Maryland in 2006, is headquartered at 8110 Maple Lawn Blvd in Fulton, Maryland, and now lists 39 locations. It is licensed as a home improvement contractor in Maryland (MHIC #124358), Virginia, D.C., Pennsylvania, New Jersey, Connecticut, Florida and other states, with license numbers in its site footer. Private equity firm AEA Investors has owned it since July 2021.
The BBB rates Window Nation, LLC A+ and has listed it as accredited since November 27, 2024, with 406 complaints in 3 years. In 2022 the company paid a penalty under an expedited EPA settlement under the Toxic Substances Control Act; the public docket doesn’t say what the violation was. Check your state license lookup before you sign, since crews and contractor licenses vary by location.
Window Nation cost
Window Nation doesn’t publish prices. You get a quote at a free in-home consultation, and the price depends on the number of windows, size, style, glass package and any trim or repair work. The company says designs are made to fit your budget.
Most quotes come with a promotion. In October 2026 the offer is buy 4 windows, get 4 free on certain models, with a 4-window minimum, labor excluded, plus $0 down and 0% interest for 2 years, then 17.99% APR. Free-window offers only help if the starting price is competitive, so compare the total installed price, not the discount. Ask whether the financing is deferred interest and who the lender is.
Window Nation warranty
Window Nation offers a limited lifetime warranty on defects for as long as you own the home. It covers vinyl frames and sashes, glass seal failure that causes fogging, screen frames and mesh, and hardware such as locks, balances and rollers. The warranty page also says “Excludes Labor,” so ask in writing whether service visits after the first year are charged.
To transfer it to a buyer, email [email protected] within 60 days of the sale; the company quotes the transfer cost and second-owner terms after the request. The warranty can be voided by drilling blinds into the frame, painting or tinting the glass, vandalism or acts of nature.

On Trustpilot, Window Nation averages 4.3 out of 5 across 4,593 reviews, with 72% five star and 9% one star. Praise centers on courteous installers and fast, clean installs. The 406 BBB complaints and the negative reviews focus on reaching service after installation, defects such as missing trim or uneven pieces, long delays and disputes over balances and refunds. Some reviewers also describe high-pressure sales.
- Get every promise, including installation date and trim work, in the written contract.
- Don’t make the final payment until you’ve inspected each window.
- Photograph serial number labels so you can file a warranty claim later.
Canceling a Window Nation contract
Window Nation doesn’t publish a cancellation policy online. Under the FTC Cooling-Off Rule, you generally have until midnight of the third business day to cancel a sale of $25 or more made in your home, and the seller must give you a cancellation form. Many states add their own home improvement contract rules. Because windows are custom-built, cancellation after the rescission period can cost you, so decide before the window closes.
Who should skip Window Nation
If you want a wood, fiberglass or composite frame, Window Nation’s vinyl-only lineup won’t fit. If you only need one or two windows, the 4-window promotion doesn’t help and a local installer may quote less. If you dislike in-home sales visits, start with retailers that price online.
Alternatives to Window Nation
- Renewal by Andersen Better if you want a composite frame with a wood look and will pay more for it. Read review
- Lowe's window installation Lets you choose name brands such as Pella and JELD-WEN and compare prices online before anyone visits. Read review
- A local licensed installer Often quotes lower for the same class of vinyl window; check the state license, insurance and EPA lead-safe certification for homes built before 1978.
