Founded in 1988 by Larry Gravina, the family-owned business is now in its third generation of operation. Larry began working in the industry in 1972, spending 16 years learning the trade before establishing the company.

The team has overseen more than 100,000 successful projects. Unlike big-box stores or national chains, Gravina’s operates as a broker for windows, carrying over 50 lines from top manufacturers to provide diverse options for various budgets. Product offerings include vinyl, steel, and composite siding, as well as wood, aluminum, and fiberglass window frames. They also provide custom builds for do-it-yourself projects and offer Low Emissivity and sound-reducing STC/OITC glass options.

Clients can schedule in-home or showroom appointments to review samples and receive multiple quotes. In-home visits require 24 to 48 hours of advance notice. Payment is accepted via cash, check, major credit cards, or financing through Wells Fargo. The company guides customers through ENERGY STAR options and explains that windows are typically installed prior to exterior façade replacement. Lead times for installation are 4 to 8 weeks after ordering, with longer waits common in late summer and fall. Upon completion, paperwork is mailed within 7 to 10 business days.
