What Island construction does

Island Construction Corporation is a privately held, founder-owned construction services firm headquartered in Del Mar, California, founded in 1982 by Kevin Hennessy. The company delivers residential and commercial outdoor construction, with core services spanning backyard renovation, deck and patio construction, pool construction and remodeling, hardscapes, and ADA pool lift installation. It operates a wholly-owned division called Stainless Aquatics focused on stainless steel pools, swim spas, and hot tubs, including non-standard installations on boats and rooftops. Technical capabilities include shotcrete construction (membership in the Shotcrete Concrete Contractors Association), the Duraglass multi-layered fiberglass resurfacing system, and full ADA compliance work to NEC 680.26. The firm holds California General Contractors License B 446405 and Swimming Pool License C53 446405.

The company serves three primary customer segments: residential property owners seeking custom outdoor living spaces, hospitality operators (hotels, resorts, country clubs) requiring high-end pool and amenity construction, and homeowner associations and property management companies managing community amenities. Notable hospitality engagements include work for Four Seasons Aviara, Four Seasons Residences, Hilton San Diego, Hilton Garden Inn Marina Del Rey, Omni San Diego, and Oceanside Pier Resort. The firm reports 600+ completed projects and 300+ satisfied clients across 33+ years of operation, with a portfolio spanning San Diego, Southern California, Northern California, Florida, Arizona, Texas, Utah, and New York.

The business model is project-based custom construction, with revenue generated through one-time contracts priced per scope. Pricing is quote-driven with free estimates and consultations; no public rate cards exist. Go-to-market is sales-led and direct-to-consumer, relying on the company website with project galleries, social sharing, and direct phone/contact-form inquiries to generate leads. The firm markets to both consumer and commercial buyers, positioning end-to-end project management across multiple specialties as the primary value proposition.
