Wonder Windows

What Wonder Windows does

Wonder Windows is a privately held, second-generation family-owned window and door retailer and installer headquartered in Rochester, New York, founded in 1962 by Arthur Lazeroff and now operated by Mark Lazeroff with his son Scott. The company sells replacement windows (double hung, casement, slider, picture, awning, bow/bay, European tilt/turn) in vinyl, wood, and composite materials, alongside entry doors (steel and fiberglass), sliding patio doors, and storm doors from a manufacturer roster that includes OKNA, Andersen, Starmark, Sierra Pacific, OKNOPLAST, ProVia, and Larson, in addition to its proprietary Wonder Series. Operations run across three showroom and warehouse locations in Rochester, Buffalo, and Syracuse, serving more than 100 communities across Western and Central New York.

The business is sales-led and vertically integrated: field sales representatives conduct in-home consultations and provide free estimates, while in-house trained installers (not subcontractors) execute installations with lifetime transferable warranty coverage on parts and labor for the Wonder Series. Three distinct go-to-market channels coexist — full-service DTC in-home sales with installation, a DIY channel offering Pick Up, Measure & Deliver ($15/window, 5-window minimum) and Wonder Installation in the Greater Rochester area, and a dedicated wholesale/commercial division supplying contractors and builders with OKNA, Andersen, Sierra Pacific, Trimline, and related brands. Revenue is primarily one-time product sales plus installation fees, supplemented by partnered consumer financing (0% interest, low-interest, and same-as-cash/deferred plans underwritten via Momnt Technologies).

Customer concentration is centered on residential homeowners in Upstate NY seeking energy-efficiency upgrades, supplemented by a contractor/builder wholesale segment and a small DIY segment. The company holds BBB A+ accreditation, 2024 Rochester Top 100 #15 ranking, EPA Lead-Safe Certified Firm status, and ENERGY STAR Most Efficient 2025 certification, and operates community programs such as Wonder for Warriors, Roc Solid Foundation, and Habitat for Humanity builds. No public revenue, headcount, or funding disclosure is available, and ownership remains entirely within the Lazeroff family with no external institutional capital.
