Sentinel Contracting LLC is a licensed and insured exterior remodeling contractor serving homeowners, property managers, and business owners across Westchester County, Rockland County, Dutchess County, the Bronx, and surrounding areas since 2015.
A licensed exterior contractor provides roof replacement and repair, siding installation and replacement, window replacement, and masonry work, including pointing, chimney repair, and retaining walls and stoops. These services address structural and weatherproofing needs on residential and commercial buildings, and a single licensed contractor can coordinate multiple trades on one project to reduce cost and scheduling complexity.
Roofing and Siding Built for the Northeast
Missing shingles after a northeast storm, water staining on soffits, or a sagging section of roof are not cosmetic issues. They signal moisture reaching the structure underneath. Sentinel Contracting replaces full roofs and completes targeted repairs using materials rated for the northeast climate, including architectural asphalt shingles, ice-and-water shield underlayment, and ridge-cap finishing. All work is completed by fully trained staff to code.
We install and fully replace siding in vinyl, fiber cement, and wood, matched to Westchester County and Hudson Valley residential architecture. Siding failure such as rot, warping, or impact damage accelerates moisture intrusion into the structural layer, which makes replacement a structural priority, not a cosmetic one. Sentinel Contracting installs and replaces siding as a standalone service or as part of a larger exterior scope.
Window Replacement and Masonry — One Contractor, One Schedule
We install double-hung, casement, and picture windows, using energy-efficient double-pane units suited to the northeast climate and compatible with the older housing stock common to Westchester County, Yonkers, and the Bronx. Having a single licensed contractor manage window replacement alongside roofing or siding work means one schedule, one point of contact, no gaps between trades, and no disputed responsibility when work areas overlap.
We handle concrete and brick pointing, chimney crown repair, parapet walls, stoops, and retaining walls, the exterior masonry elements common to Northeast residential and commercial properties. Masonry repair addressed early prevents more expensive structural failure. Masonry repair is routinely scoped alongside roofing on the same project, which reduces mobilization costs for the client.
