Construction Services in Key Largo, FL

If you’re planning a remodel, addition, or storm-hardening project on Key Largo, you already know this island doesn’t play by mainland rules. The limestone bedrock sits just inches under your feet, the salt air eats ordinary hardware, and Monroe County’s permit system moves to a rhythm all its own. Barrett & Sons Construction has navigated every one of those hurdles on jobs from Ocean Reef to Tavernier Creek. When you call (877) 610-1318, you’ll reach a live person who knows Key Largo’s codes, its inspectors, and its quirks – not a call center in another state. We’ll give you a straight answer and an honest price, in writing, before any work begins.

Why Key Largo Homeowners Choose Barrett & Sons Construction

Homeowners in Key Largo don’t hire contractors the way people do on the mainland. Here, the wrong contractor can leave you with a permit that never closed, a piling that wasn’t driven deep enough, or a window that won’t survive the next big blow. That’s why folks in Rock Harbor and the Angler’s Club neighborhood call us. Our crews have run jobs on every stretch of the island, and we’ve built a reputation for one thing that matters above all: we show up, we do what the contract says, and we answer the phone when you call.

Tom Barrett founded this company in 1998, and his sons run the crews to this day. That means the name on the truck is the name that stands behind the work. We carry premium brands like GAF on roofing and Schluter in bathrooms, not mystery materials off a van. Every job includes permits pulled, inspections signed, and a written change order before any scope change touches the project. And every completed job carries our 90-Day Done Right Promise in writing: if it’s not right, Tom comes back and makes it right, one call.

Roofing

A roof on Key Largo has to survive 150+ mph winds, driven rain, and the relentless salt spray off Florida Bay. We install GAF Key Largo Roofing systems with HVHZ-rated assemblies and continuous load paths that meet Monroe County’s wind code, not just the state minimum.

Windows & Doors

Impact-rated openings aren’t a luxury on this island; they’re the code. We install Windows & Doors - Key Largo engineered for the High-Velocity Hurricane Zone, with stainless hardware that won’t corrode in the salt air.

Windows & Doors

Fence Installation

Fences on Key Largo take a beating from wind, salt, and sun. We build with materials and fasteners rated for marine exposure, and we set posts deep enough to handle the storms that roll through every summer.

Fence Installation

Driveway & Pavers

Driveways here sit on coral rock, not soft Florida soil, which changes how the base gets prepared. We install paver driveways and patios with proper compaction and drainage so they don’t settle or heave in the first two years.

Driveway & Pavers

Home Additions & ADU

Adding square footage on Key Largo means navigating ROGO allocations, flood elevation requirements, and pilings driven to bedrock. We manage the whole process from engineering through the final inspection, with every permit and every approval in writing.

Whatever the scope, start with the home page to see how we work.

Why Key Largo’s Climate & Housing Affect Construction

Key Largo sits directly atop the Key Largo Limestone formation, a fossilized coral reef that surfaces just a few feet below grade. That changes everything about how we build here. You can’t trench for utilities the way you can in Homestead or Florida City; you drill into rock. Footings aren’t poured, they’re driven – pilings anchored into bedrock, because the ground itself won’t hold a conventional foundation. Any contractor who hasn’t worked this geology learns it the hard way, usually by burning through a few bits on a rock saw and then asking for a change order. We know what’s under the ground because we’ve been drilling it for years, and we price for it from day one.

Then there’s the housing stock. Much of Key Largo was built in the 1960s through the 1980s, before Monroe County adopted its post-Hurricane Andrew High-Velocity Hurricane Zone codes. Pre-1992 homes routinely lack code-compliant roof-to-wall connections, continuous load paths, and impact-rated openings. Storm-hardening retrofits are among the most common scopes we quote on this island – and among the most important. The salt air and humidity don’t help, either. We spec stainless steel or hot-dipped galvanized hardware as a baseline on every job we run in the 33037, because the alternative is rust stains and failed anchors within a few years.

Pricing for Construction in Key Largo

Honest numbers matter, so here’s what you’re looking at. Kitchen remodels on Key Largo typically run $45,000 to $110,000 depending on cabinet grade and structural work. Bathrooms land between $22,000 and $55,000. Roof replacements on an island home run $18,000 to $45,000, influenced by tile versus standing seam. Impact windows and doors usually fall between $25,000 and $70,000 for a full house. Driveways and pavers start around $12,000. Home additions and ADUs are the most variable, from $180,000 up past $400,000 once pilings, ROGO allocation, and flood elevation factor in. Every quote we give is a written, line-item price. If the scope changes, so does the change order – in writing, before any work moves forward. Call (877) 610-1318 for a free estimate.

How Much Does a Roof Retrofit Cost in Key Largo?

Most storm-hardening retrofits on Key Largo – adding hurricane straps, impact-rated decking, and code-compliant roof-to-wall connections – run between $8,000 and $25,000, depending on your existing roof assembly and whether the sheathing has to come off to reach the trusses. If you’re also replacing the roof covering at the same time, you’ll save on labor and tear-off compared to doing the two jobs separately. The cheapest time to harden a roof is when it’s already coming off. Call (877) 610-1318 and we’ll walk your roof before you sign anything – estimates are free.

Will the Price Change Once Work Starts?

Only if the scope changes, and only with your signature on a written change order first. That’s how we’ve operated since Tom founded the company in 1998. If we hit something unexpected – and on Key Largo, with rock under every job, sometimes we do – you’ll know what it costs before the work continues, not after the invoice arrives. The allowance that isn’t on paper is a surprise waiting for a date, and we don’t do surprises.

What Key Largo Customers Say

★★★★★ 4.8 from 10+ reviews

"Full kitchen down to the studs. He found the previous owner had done the wiring himself and it was genuinely dangerous, showed me, and put it right properly rather than boxing it back in."

- Augustus Nwachukwu

"He pulled every permit and had every inspection signed off. The last contractor we used told us permits were optional and I have been paying for that ever since."

- Redmond Cavanaugh

"Genuinely good builders and I would use them again. Site tidiness slipped a bit in the middle stretch and I had to mention it, after which it was spotless every evening."

- Marcus Threadgill
