About Us

Building Trust, Crafting Excellence Since 1975

Founded in 1975 on the beaches of East Hampton, Sandpebble began as a small family-run construction firm built on trust, craftsmanship, and a commitment to turning clients’ visions into reality. Guided by founder Victor Diez-Canseco’s engineering expertise and passion for precision, the company quickly earned a reputation for quality and integrity. What started as a local residential builder soon evolved into a trusted name recognized for excellence across Long Island — even earning a feature in Architectural Digest in 1983.

Over five decades later, Sandpebble has grown into a leader in public-sector construction management, known for its client-first approach, “The Sandpebble Way.” With a legacy rooted in transparency, innovation, and community partnership, the company continues to shape spaces that serve and inspire. Today, under the leadership of the next generation, Sandpebble remains dedicated to the same values that started it all — strength in simplicity, balance in detail, and an unwavering foundation of trust.

What Our Client Says About Us

Learn More About Us

I’m at a loss for words to succinctly describe almost two decades of our history. Over multiple projects spanning nearly twenty years, ranging from building reviews, HVAC projects, renovations, and new construction, Sandpebble has been an invaluable partner along every step of the journey. Truly defining preconstruction services, including facilitating community charettes, budget planning, architect evaluations, and constituent communications, I wouldn’t consider beginning any construction project without adding them to the team at day one. Sandpebble = a value-add to every project.

Kerri Rosalia

Director Mastic Moriches Public Library

Sandpebble Project Management did an exceptional job with project management on the recently completed renovation of two areas of the West Islip Public Library. Their expertise was critical to the success of the project. They were involved in all aspects of the project, from its initial planning, the selection of the architect and MEP engineers, the organization of plans and specifications, the bidding and RFP process, and in the coordination and supervision of the various contractors. They were proactive in anticipating and solving problems, and their communication, both with the library and the various parties involved with the project, was first rate. I was very happy with the entire process and would use them again in a heartbeat.

Andrew Hamm

Director West Islip Public Library

Sandpebble’s talented team guided us through the myriad decisions that needed to be made and they were always responsive to our inquiries, which allowed the Board of Trustees to make fully informed decisions. Sandpebble oversaw the entire project and ensured that all work was completed professionally, in accordance with the Village’s specifications, and ahead of schedule. Their knowledge and advice were invaluable, as was the preconstruction sequencing of the project they provided…I recommend Sandpebble to you without reservation.
