Committed to excellence. Doing it right the first time.
Jeremy Trantina founded JAT Specialties in 2006, bringing with him a career built across civil engineering, construction administration, architectural project management, site supervision, site design and surveying. That mix is unusual for a homebuilder, and it is the reason our clients tend to get straight answers about sites, structures and budgets rather than optimistic ones.
Mitchell Trantina joined his father in the family business in 2016, and Mason Trantina joined the team in 2023. Between them they carry more than forty years of construction experience. We build traditional wood-frame homes throughout Walton County and specialise in Insulated Concrete Form construction, because a house on this coast should stand up to the strongest storms and still be one of the cheapest on the street to cool.

Founder & Licensed Contractor
The Team
A family company. The people who own the business are the people who show up to build.

Founder & Licensed Contractor
Founded JAT Specialties in 2006 and holds Florida Certified Building Contractor licence CBC1255741. Over twenty-five years across civil engineering, construction administration, architectural project management, site supervision, site design and surveying. Hands-on, on site.

Project Manager
Joined his father in the family business in 2016 and works alongside him on every project, sharing the same commitment to fine craftsmanship, attention to detail and seeing each job through properly.

Estimating & Site Development
Joined the JAT Specialties team in 2023 after earning his Bachelor’s in Construction Engineering from the University of Central Florida. With a background in civil engineering, estimating and site development, Mason brings a strong technical and analytical perspective to every project, bridging the gap between design, construction and project planning so jobs are accurately estimated, efficiently managed and built to the highest standards.
What We Believe
The values that guide every job.
The company was built on getting it right rather than getting it done twice. It costs less, it takes less of your time, and it is the only version of this job we are interested in doing.
We build on the Gulf Coast, so we build for the weather that comes with it. That is why we push ICF and concrete, strength and energy efficiency are the same decision here.
Attention to detail is not a slogan on a truck. It is the trim that lines up, the tile that runs out evenly, and the punch list that is genuinely finished before we leave.
We are focused on building long-lasting relationships with our clients. Most of our work comes from people who have already been through a build with us.
