What Cornerstone Builders does
Cornerstone Builders (legal entity: Cornerstone Builder Inc.) is a privately held construction services firm headquartered at 100 Red Schoolhouse Rd, Spring Valley, New York, serving the Hudson Valley region of New York State. Founded circa 2003, the company operates with a 1–10 employee headcount and has built a two-decade operating history focused on three integrated service lines: custom residential home building (Custom Build & Design / New Homes), additions and renovations (sunrooms, extra bedrooms, decks, kitchen and full-home remodels), and commercial development for local business and community projects. The business model is project-based: revenue is generated through negotiated, quote-driven contracts scoped to each engagement, with no disclosed standard pricing, no recurring revenue streams, and no subscription or licensing component.
Customer acquisition is conducted through direct-to-consumer channels: a Squarespace-hosted website (cornerstonebld.com) carrying a project portfolio, service pages, a design blog, and an email newsletter signup; plus prominent phone and email contact points for consultation requests. The firm targets two customer segments — residential homeowners seeking bespoke builds or renovations, and commercial clients seeking time- and budget-disciplined project delivery — within a single regional geography. There is no disclosed technology platform, no proprietary software or AI/ML capabilities, no external funding, no partnerships, no certifications, and no public revenue or backlog data; the company's competitive position is grounded in local brand reputation, an experienced small team, and a portfolio of completed residential and commercial works.
