For 35 years, Diapoules & Sons has delivered luxury construction defined by craftsmanship and detail. Today we bring that same standard to large-scale commercial projects — strengthened by a leadership team who have delivered developments exceeding $100 million.
Diapoules & Sons made its name framing and finishing some of the most technically complex luxury homes in Martin County — beginning in Sailfish Point. That discipline now anchors a broader capability: ground-up commercial construction delivered at scale, led by a team with nine-figure project experience.
New commercial builds from sitework through certificate of occupancy, managed with the schedule and budget certainty large projects demand.
Complex, multi-trade developments that pair residential-grade finish quality with commercial-scale delivery.
Shell contracting and tenant improvements — a long-standing strength of the firm, now offered across larger commercial footprints.
Custom homes, additions, and complex renovations at the highest standard of craftsmanship — the work that built our reputation.
Early cost planning, value engineering, and realistic scheduling so decisions are made before they become expensive.
Full-scale remodeling and structural additions executed with minimal disruption and rigorous quality control.
On a major incident, you don't arrive and start figuring it out. You size up the situation, set a plan, establish command, assign responsibilities, keep everyone communicating, anticipate what can go wrong, adapt as conditions change — and stay with it until the job is done. That is exactly how an owner wants their project managed.
Mike and Jim didn't start at the top. They came up as paramedics — solving problems firsthand, under pressure — and rose to lead as Battalion Chiefs, responsible for people, resources, risk, and complex operations. That progression, from doing the work to commanding it, is the foundation of how Diapoules & Sons runs every build. Few construction firms can legitimately say the same.
Selecting a builder for a nine-figure project is a decision about trust, delivery, and leadership under pressure. Here's what sets our team apart.
Our new partners have led and delivered commercial developments exceeding $100 million — bringing the systems, subcontractor networks, and financial rigor that projects of that size require.
Three decades of relationships with the region's best trades, inspectors, and suppliers — and a reputation for finish quality that commercial clients rarely find in a firm this established.
A command-and-safety culture carried directly from 52 combined years in fire rescue — protecting your site, your schedule, and everyone on it, especially when conditions get difficult.
Every project runs on Buildertrend or Procore, giving owners a single secure portal for schedule, decisions, budget, and progress — no surprises, at any scale.
A selection of large-scale commercial, hospitality, education, and multifamily projects our team has helped bring from groundbreaking to grand opening — alongside the luxury residences that built our name.

We are a family-owned and operated construction business, founded in 1990 by Steve Diapoules as JMK Construction, Inc. In the early years, the company built its foundation working in Sailfish Point, framing some of the most high-end and technically complex homes in Martin County — projects that shaped our commitment to craftsmanship, precision, and pride in our work.
Today the business is owned and operated by his sons, Mike and Jim Diapoules, under the name Diapoules & Sons Construction. We are proud to carry forward the strong legacy established by our father — one rooted in putting the customer first and striving for excellence in every detail.
Today, the business is owned and operated by Steve's sons, Mike and Jim Diapoules, under the name Diapoules & Sons Construction. Long before taking ownership, Mike and Jim worked alongside their father for more than 30 years, learning the construction field from the ground up. They started at the bottom, gained hands-on experience in every aspect of the business, and worked their way up to eventually owning and operating the company. They are proud to carry forward the strong legacy established by their father — one rooted in craftsmanship, putting the customer first, and striving for excellence in every detail.
Mike and Jim also bring a unique background in public service, with over 52 years of combined experience in fire rescue. Construction, much like emergency management, demands clear communication, leadership, and the ability to overcome challenges as they arise. Our vision mirrors the values we upheld in fire rescue: take care of people first. We treat every project as if it were our own. Diapoules & Sons Construction is a d/b/a of JMK Construction, Inc.
