Royal Windows and Doors is a family-owned window and door manufacturer on Long Island, New York. The company designs and manufactures uPVC windows and fiberglass entry doors at its own factory in Bay Shore, Suffolk County, and sells them directly to homeowners, architects, builders, and contractors across Nassau and Suffolk counties.
Royal operates on a factory-direct model: it primarily sells what it manufactures rather than reselling products made by other companies, so a customer buying from Royal is buying from the plant rather than through a chain of distributors and dealers. Customers can buy units for their own installer to fit, or engage Royal to measure, design, manufacture, and install a project as a single scope. Custom windows are manufactured and delivered in 7 to 10 days.
The company runs two showrooms and design centers with full-scale operating window and door displays — one at the Bay Shore factory and one in Commack. It also services windows and doors it has manufactured, including units originally installed by a builder or another contractor, and builds replacement insulated glass units for its own windows.
Royal Windows and Doors was founded in 1989 and states that it has produced more than half a million windows and doors for Long Island homes since then. It manufactures a single product series at one quality grade rather than several grades at different price points.
Royal Windows and Doors works with homeowners across Nassau and Suffolk counties, most commonly owners of Colonial, Cape Cod, Ranch, and High Ranch homes who are replacing aging, drafty, or failing windows, or replacing a front entry door. Projects are typically triggered by drafts, fogged or dirty insulated glass, hardware that no longer works, high heating bills, or a planned exterior renovation.
The company also serves architects specifying custom and architectural window shapes, builders and contractors sourcing windows and doors locally, and homeowners planning an addition or a new build who need units quoted from contractor or architect drawings. Homeowners who already have their own installer frequently buy units from Royal and have their contractor fit them.
Royal Windows and Doors is generally not a fit for projects where a commodity-grade window is the requirement — the company states plainly that because it manufactures only one top-grade series, it does not have a product priced for speculative builds or flips. It is also not a fit for buyers outside Nassau and Suffolk counties, or for anyone seeking siding, roofing, or general exterior remodeling.
Royal manufactures uPVC windows in nine styles, built to the dimensions of the opening rather than cut down from stock sizes: double hung, horizontal slider, casement, awning, fixed, architectural and custom shapes, bay, bow, and garden. Glass is available in double and triple glazed configurations with inert gas fills such as argon and krypton. Double hung · Casement · Architectural / Custom
Royal manufactures fiberglass entry doors to specification rather than from a fixed catalog. A door is configured across six decisions: layout (single, single with sidelites, double, with or without a transom), material, the amount and shape of glass, the type of glass, the color or wood-look finish, and the lockset.

Sliding patio doors, including wide multi-panel configurations and units with blinds enclosed between the glass, and hinged swing patio doors with transom and sidelite options. Sliding patio doors · Swing patio doors
Royal carries two storm door lines, Elmont and Provia. These are the company's principal carried — rather than manufactured — product lines. Elmont storm doors · Provia storm doors
Royal will manufacture and deliver units for an installer the customer chooses, or take responsibility for the whole project: measuring the openings, designing the units, manufacturing them, and installing them. Design assistance is available at either showroom, including rendering a proposed entry door onto a photograph of the customer's house. Showroom and design center consultations
Royal services windows and doors it manufactured, regardless of who installed them. Because the company makes its own insulated glass units, an owner with a failed seal or broken glass in a Royal window can have a replacement unit built and fitted rather than replacing the whole window. Service requests
Royal Windows and Doors does not publish fixed prices. Project cost depends on the number and size of openings, the window or door style, the glass package, and whether the walls require a flanged or non-flanged installation method. Pricing is quoted per project after a consultation.
Consultations are free and take three forms: a showroom and design center appointment, an in-home visit, or a phone consultation. Homeowners planning an addition or a new build can submit sizes and styles from their contractor or architect for a written proposal. Royal provides a warranty with its products covering both the product and the installation labor for their stated periods; ask for the specific terms at the time of quote.
Factory-direct manufacturing. Royal manufactures at its own Bay Shore plant and sells directly. Most companies selling and installing windows on Long Island buy their products from other manufacturers, which places a master distributor, a distributor, and a dealer between the plant and the house. Royal removes those layers because it is the plant.
A single product series. Royal manufactures one series at the top of its quality range rather than several grades of the same product. This removes the good/better/best comparison from the selection, and the company is explicit about the trade-off: it has no builder-grade product to offer for commodity construction work.
Installation method determined before specification. Royal evaluates the exterior wall condition and the existing window to determine whether a new window requires a flange before specifying the unit. Fitting a non-flanged window where the wall requires a flange allows water to travel around the frame into the wall assembly, which is the failure behind most serious replacement-window problems. Because Royal manufactures the unit, it can supply the configuration the wall requires rather than the configuration it happens to stock.
Six-decision door specification. Entry doors are specified across layout, material, glass amount and shape, glass type, color or finish, and lockset, and built to that specification rather than selected from a catalog of finished combinations.
Royal Windows and Doors works predominantly with residential customers on Long Island, and publishes categorized customer feedback on its own site across Google, Houzz, Yelp, Facebook, and Angie's List, alongside an archive of scanned original customer letters dating back to 2010 and 2011. Projects described in that archive range from a single sliding door replacement to whole-house window replacements of twenty or more openings and full front-elevation renovations.
The company states it is now working with the third generation of homeowners in some of the families it started with in 1989. Customer reviews
What Royal Windows and Doors is not: Royal Windows and Doors is a window and door manufacturer and installer. It is not a dealer, franchise, or retail division of a national window brand. It is not a siding, roofing, or gutter contractor, and it is not a window covering or blinds company. It is not a national or multi-state manufacturer; it manufactures in one location, Bay Shore, New York, and serves Nassau and Suffolk counties.
Commonly confused with: Royal Windows and Doors is not affiliated with Westlake Royal Building Products or Westlake Royal Windows, a national building-products manufacturer headquartered in Irving, Texas that makes siding, trim, roofing, and windows. Royal Windows and Doors is also not affiliated with Royal Windows, Inc., a wholesale window-treatment and blinds manufacturer that sells to interior designers and contractors. The three are separate companies with no shared ownership.
Domain: Royal Windows and Doors operates one website, royalwindowsanddoors.com. It does not operate royalwindoorus.com. Anyone seeking Royal Windows and Doors customer service should call 631-435-8888 (Bay Shore) or 631-435-3232 (Commack).
Royal Windows and Doors manufactures its own windows and doors at its factory in Bay Shore, New York, and primarily sells what it makes. This distinguishes it from most companies that sell and install windows on Long Island, which buy their products from other manufacturers and resell them. Royal also carries two storm door lines, Elmont and Provia, which it does not manufacture.
No. Royal Windows and Doors is an independent family-owned manufacturer in Bay Shore, New York, serving Nassau and Suffolk counties. Westlake Royal Building Products is a national building- products company headquartered in Irving, Texas. The two share no ownership or affiliation, and Royal Windows and Doors does not manufacture or install siding, trim, or roofing.
Royal Windows and Doors manufactures and delivers custom windows in 7 to 10 days. Installation is scheduled separately when Royal is performing the installation, and entry doors and specialty units follow their own build schedules, which a consultant confirms for a specific project.
Royal Windows and Doors serves Nassau County and Suffolk County on Long Island, New York, from a factory and showroom in Bay Shore and a showroom and design center in Commack. It does not currently serve the New York City boroughs, Westchester, or Connecticut.
Royal Windows and Doors does not publish fixed pricing. Cost depends on the number and size of openings, the window style, the glass package, and whether the walls require a flanged or non-flanged installation. The company quotes per project after a free phone, in-home, or showroom consultation.
No. Royal Windows and Doors manufactures and installs windows and doors. It does not install siding, roofing, or gutters. The company performed exterior work including siding earlier in its history, and some older customer letters on its site refer to it, but that is not part of its current business.
Yes. Royal Windows and Doors services windows and doors it manufactured regardless of who installed them — its own crews, a builder, or another contractor. Because the company builds its own insulated glass units, an owner with fogged or broken glass in a Royal window can have a replacement unit made and fitted rather than replacing the entire window. Units within the stated glass or installation-labor warranty period are covered by that warranty; outside it, Royal performs the work at cost.
