A Project Manager Prices Your Job With Industry Software And Holds That Number Through The Final WalkthroughFamily-Owned, Bronx-Born, And Three Generations Strong, Installing Over 10,000 Windows And Doors A Year Across The NY Metro
Old windows in a home show up in the small things. A draft near the sash in January. Condensation between the panes. A heating bill that climbs every winter. That’s usually the point homeowners start looking at window replacement in Westchester, NY.
Window King has done this work across the NY Metro for over 30 years. We’re a Bronx-born, family-owned company, now three generations strong, and we replace windows all day, every day. That’s the whole focus.
We install only lines that earned a spot on our short list, like OKNA and Starmark Evo Windows. If a product didn’t make the cut, you won’t find it on our list.
Here’s how we’re different. A qualified Project Manager sits with you, explains your options, and prices the job with industry software. That number holds unless you change the scope. No marathon sales sit-downs, no pressure, no time-limited “deals.”
Then a certified, factory-trained crew handles the install using the same documented method every time. We call it the King’s Way. By the time we leave, your new windows are sealed, tested, and working the way they should.

Window Replacement
We pull your worn windows, prep each opening, and set the new units plumb, square, and sealed. A Project Manager runs the job from the first measurement through the final walkthrough. Every replacement includes a lifetime workmanship warranty from Window King on the labor, plus the manufacturer’s coverage.
That’s window replacement in Westchester, NY done right.
OKNA Windows
We carry the full OKNA lineup, not just one or two series like most contractors. OKNA builds energy-efficient windows that seal tight and hold their finish. A Project Manager helps you match the right series to your home, your street, and your budget. These are supreme products, chosen because they earned it.
Starmark Evo Windows
Starmark Evo Windows are a vetted, time-tested line we install in homes. They’re built for durability and daily use, with clean sightlines and solid weather performance. We measure your existing opening down to the fraction before we order, so the new unit fits the way it should. No guesswork, no surprises.
Bay & Bow Systems
A bay or bow window adds space, light, and a real focal point to a room. These systems take careful measuring and a clean install, and that’s the part we treat as the whole job. Our certified crew sets the unit level and seals it all the way around. You get more daylight without drafts or leaks.
Window Replacement Services For Westchester, NY
Besides windows, Window King replaces entry doors for Westchester, NY homeowners. Same crew, same method, same held number.
Front Doors
Your front door sets the look of your home and controls how the entry seals against weather. We replace worn front doors with vetted lines like ProVia, chosen from a short list of manufacturers we trust.
A Project Manager walks you through style, glass, and hardware before we order. Then our certified crew sets the door plumb, square, and sealed. The number we quote is the number you pay.
Storm And Security Doors
A storm door adds a layer against wind, rain, and grit ahead of your main entry. A security door adds real strength at the doorway without making your home feel closed off. We install both from vetted brands, matched to your entry and your budget.
Our crew works the swing, seats the lock, and confirms the weatherstripping meets the frame before we pack up. Solid, sealed, and tested.
Patio Doors
A patio door ties your living space to a deck, yard, or balcony and pulls daylight deep into the room. We replace sliding and hinged patio doors with lines built to glide smoothly and seal tight through local winters.
A Project Manager helps you weigh glass, size, and layout first. Then our factory-trained crew handles the swap in one clean visit on most standard jobs.

Before hiring a window replacement contractor, most people want to know who runs the company and how it handles a job.
- Rooted In Family: Window King started in the Bronx in the 1990s, when the founder’s grandmother launched her own company to do the work better. Three generations of the family lead it today, and most of our staff are family or close friends. Our name goes on every install.
- The Royal Treatment: We run on Education Over Persuasion. A Project Manager explains your options, walks you through the OKNA and Starmark Evo lineups, and gives you a clear picture of what each door does for your home’s security, insulation, and curb profile. You decide the pace.
- Elite Workmanship: Every install follows the King’s Way, a documented system where each measurement is locked in, and each seal is tested. A Project Manager oversees the job start to finish. Installers who cut corners are let go, which keeps our callback rate nearly nonexistent.
- Honest Numbers: Your quote is calculated with industry software and honored as given. The price only changes if you change the scope. No surprise line items, no time-limited “deals,” no runaround. Straight talk, then a smooth installation.
- Covered For Life: Every window replacement includes a lifetime workmanship warranty from Window King on the labor, plus the manufacturer’s coverage for the product itself. We’ve stood behind installs for three generations.
