CORNERSTONE BUILDERS

What CORNERSTONE BUILDERS does

Cornerstone Builders is a family-owned design-build residential construction and remodeling contractor founded in 2003 in Beaverton, Oregon, serving the Portland Metro area across Washington, Clackamas, and Yamhill Counties. The firm delivers a full suite of services including whole-home remodeling, kitchen and bathroom renovations, basement finishing, home additions, ADU construction, new custom home building, and specialized aging-in-place modifications. Its operational backbone is an integrated Design-Build methodology in which a single dedicated project manager handles design, permitting, subcontractor coordination, and client communication from initial consultation through final walkthrough, supported by 3D digital modeling for pre-construction visualization.

The business operates on a project-based, one-time-engagement revenue model with quote-based pricing determined by scope, material selection, and structural complexity. Go-to-market is consultative and local: direct in-person consultations, free estimates, and inside-sales inquiry handling feed a sales-led pipeline targeting affluent residential homeowners in mid-to-luxury property brackets. Distribution is regional and direct, relying on field sales, local SEO, a Houzz profile, social media, and content marketing rather than any third-party channel partner.

Cornerstone is a private, family-controlled entity with no outside investors, parent company, or disclosed funding rounds. Owner Allen Tankersley, who holds the NAHB Certified Aging-in-Place Specialist (CAPS) designation, leads a small team of 1-10 employees and leverages subcontractors for trade work. The firm has earned consecutive NARI Contractor of the Year awards from 2022 through 2025, holds a 4.9/5-star rating across 72 verified reviews, and has operated continuously for over 20 years in a market where local reputation is the primary competitive differentiator.
