D7 Consulting

What D7 Consulting does

D7 Consulting, Inc. is a privately held B2B professional services firm headquartered in Newport Beach, California, that has provided building envelope consulting since its founding in 1993. The firm specializes in the design, quality assurance, construction administration, and forensic testing of roofing, waterproofing, and weatherproofing systems for commercial, institutional, and high-end residential construction projects. Its client base includes architects, real estate developers, property owners, general contractors, and legal professionals, with notable engagements spanning aviation (LAX Bradley West and MSC North, John Wayne Airport Terminal C), sports and entertainment (Banc of California Stadium, L.A. Live, Hollywood & Highland), cultural and civic landmarks (Walt Disney Concert Hall, Music Center Plaza, Cathedral of Our Lady of the Angels), healthcare (Ventura County Medical Center), and education (USC Michelson Center). The firm has completed 4,857 projects since inception and describes itself as one of the leading building envelope consulting firms on the West Coast.

D7 delivers a unified suite of seven service areas — design and specifications, restoration/replacement, due diligence, construction administration, quality assurance observation, electronic leak testing (using Electronic Vector Mapping and ASTM/AAMA criteria), and litigation support — rather than a discrete software or technology product. Its operational technology stack includes iPad-based field reporting with cloud (Box.net/iCloud) data uploads, AutoCAD for design drafting, and Electronic Vector Mapping (EVM) for non-destructive leak detection in waterproofing membranes. The firm has long-standing education partnerships with the Roof Consultants Institute (RCI, now IIBEC) and holds product certifications with manufacturers including Cetco and NEOGARD.

The firm generates revenue through project-based professional services fees billed under multi-year contracts to enterprise and government clients, secured primarily through direct relationships, repeat business, and industry referrals rather than traditional sales channels. It maintains a small team of 11–50 employees, including registered architects, certified QA observers, electronic leak technicians, and administrative staff, with 100+ years of combined building envelope experience. Marketing is conducted almost exclusively through a project portfolio website, client testimonials, and industry networking — there is no evidence of digital advertising, channel partnerships, or self-service distribution. The firm has remained founder-led (Joseph Daniels as President) and independent since 1993, with no disclosed institutional investment, acquisitions, or leadership transitions beyond organic senior hires.
