Remodeling & Construction in St. Johns, FL
Newer homes, growing families, and a need for more room.
Space for a family that has outgrown the house
The work we are asked for in St. Johns is usually additive rather than restorative. The house is not worn out — there is simply not enough of it, or the builder-grade version of a room is not the one you would have chosen.
That points at additions, accessory dwelling units, and kitchens more than anywhere else on our map. All three are permitted work, and as a Certified Building Contractor under Florida licence CBC1269967 we handle the structural side and the permit package ourselves.
St. Johns County sits directly south of Duval, so it is a short run from both our base and our Jacksonville work.
Why the work here looks different from our older markets
St. Johns sits in the northwestern corner of St. Johns County, directly south of Duval, and it has been one of the fastest-growing areas in the state — as has Nocatee, further east, which we also serve. Because so much of the housing here is genuinely new, the work looks nothing like what we do in St. Augustine: nobody is repairing age. Homeowners are adding space as families grow, finishing or converting rooms the builder left basic, and replacing standard-grade finishes with something they actually chose. The constraint is usually the subdivision lot and what it will allow, which we check before anything is designed.
What we build most in St. Johns
Adding space, adding a second dwelling, or replacing builder-grade finishes with the ones you actually chose.
How an addition runs in St. Johns
Six stages. Feasibility comes first deliberately — it is the cheapest possible moment to find out what your lot will and will not allow.
- 1
Feasibility on your actual parcel
Setbacks, lot coverage limits, and easements are set by the county and your zoning district. We confirm what your specific parcel allows before design work begins, so nobody spends money on a plan that cannot be permitted.
- 2
Design and architectural drawings
Additions frequently need stamped drawings before a permit can be issued. We confirm whether yours does at the consultation, and build to a set you already hold.
- 3
Written proposal within 48 hours
Full scope and price in writing within two days of the on-site consultation, so the decision is made on real numbers.
- 4
St. Johns County permitting
We submit the permit package, handle any corrections, and schedule every inspection. Our licensed plumbing and electrical subcontractors pull their trade permits under our master permit.
- 5
Foundation, framing, and the tie-in
New foundation and framing tied properly into the existing structure so the two move as one building. That connection is the single most important detail in an addition and it is where cheap work shows up first.
- 6
Finishes, final inspection, and walkthrough
Trades, then insulation, drywall, and the finishes you selected at Floor & Decor. County final inspection, a walkthrough with you, and your one-year workmanship warranty starts at completion.

St. Johns project questions
The five questions homeowners ask us before hiring anyone, plus two about building in St. Johns County.
It depends on the size and scope of the work, so we price every project individually after seeing it in person. As a concrete reference point, a small bathroom of roughly 7x5 typically runs $10,000 to $14,000, and a master bathroom typically runs $17,000 to $35,000, with materials included in both. Your written proposal arrives within 48 hours of the on-site consultation and lays out the full scope and price, so you are never comparing guesses. Estimates and consultations are free.
We provide them. Through our partnership with Floor & Decor you work directly with an in-store designer to choose colours, tile, and finishes, and your selections go onto a form under our account. From there we purchase, pick up, and deliver everything to the job site. You get to make the fun decisions without managing orders, deliveries, or returns.
Yes. GIL pulls and handles all permits for your project — that is part of what you are hiring a licensed contractor to do, and it is included. Our licensed plumbing and electrical subcontractors pull their own trade permits under our master permit. You do not need to contact the building department or schedule an inspection yourself.
We give you a schedule in the written proposal and we finish on or ahead of it. A small bathroom is usually about 7 days including permitting; a master bathroom is typically 2 to 3 weeks. Larger work such as an addition or new construction runs longer and is scheduled specifically for your project. We complete 30 to 40 projects a year, so our timelines come from experience rather than optimism.
Cesar Perdomo, and he manages customers exclusively. This is the structural difference at GIL: our business partner runs the job sites, so Cesar is never pulled onto a roof or under a house when you call. At most contracting companies one person does both jobs, which is exactly why homeowners cannot reach their contractor mid-project. Someone here is always reachable by phone — no run-arounds and no no-shows.
Yes. GIL Renovation Services pulls and manages every permit your St. Johns project needs, including the submission, any corrections that come back, and the scheduling of each inspection in St. Johns County. Our licensed plumbing and electrical subcontractors pull their own trade permits under our master permit. You never need to contact the building department or book an inspection yourself. Requirements and review times differ between jurisdictions and change over time, so we confirm exactly what your specific project needs before work begins rather than working from an assumption.
St. Johns sits in St. Johns County, and we build across Duval, Clay, St. Johns, and Nassau counties — Jacksonville, Orange Park, Green Cove Springs, Fleming Island, Mandarin, St. Augustine, Ponte Vedra, Nocatee, St. Johns, and Fernandina Beach. Being based in Orange Park, FL keeps all of that inside a comfortable drive, with Jacksonville our largest market. If you are just outside that footprint, call and ask: we would rather tell you honestly whether we are the right company for your job than take on work we cannot schedule properly.
