Miami-Dade County
GENERAL CONTRACTOR IN AVENTURA
High-rise interiors done to building rules, on the building's schedule.
Almost everything we do in Aventura happens above the tenth floor. That means approved packets, protected elevators, restricted work hours, quiet demolition and daily cleanup — plus a finish level that matches the address.

What Aventura homes throw at us
We price the house you actually have
Before we quote anything, we look for the conditions that turn a clean renovation into a change-order nightmare. These are the ones we find most often here.
- High-rise condo interiors with soundproofing and floor-covering requirements
- Full bathroom and kitchen rebuilds where risers and shut-offs are shared
- Impact glass and balcony-adjacent work needing association coordination
- Rental units turned over fast between tenants
Permits & approvals in Aventura
Permits through the City of Aventura and Miami-Dade, plus association approval covering insurance, work hours, elevator use and material delivery. We submit the association packet before we touch anything.

“We had water damage behind a wall that two other contractors misdiagnosed. 12X found it in an hour, handled the drying, rebuilt the drywall, and dealt with the insurance paperwork.”
“Pavers, a pergola, an outdoor kitchen, and turf — done in five weeks and permitted properly. Our backyard is the reason we stopped talking about moving.”
“We turn over rental units on tight deadlines. They have never once missed a make-ready date, and their punch lists are cleaner than anyone we've used.”
