Exterior Stone Wall Cladding

The biggest surface on the job, and the one that has to survive everything Miami throws at it.

Exterior cladding is the bulk of what Miami Stone Veneer Specialists ships. It's also where the difference between a wall that lasts forty years and one that fails in six has almost nothing to do with the stone you picked.

The wall behind the wall

Nearly every exterior veneer failure we get called about traces back to water that got behind the stone and couldn't get out. Not through it — behind it, usually around a window head or a roof junction.

On a block wall that's rarely an issue; block doesn't care. On framed construction it's the whole ballgame. You need a weather-resistive barrier, then a genuine drainage gap, then lath. Two layers, not one. The stone is a rain screen, not a waterproof membrane, and it was never meant to be.

What Miami changes

  • Salt. Within a mile of the water, use a pale face and seal it. Dark stone shows mineral bloom within a season.
  • UV. A west elevation takes punishing afternoon sun. Through-coloured stone handles it; surface-pigmented product chalks.
  • Driving rain. Hurricane-season rain arrives horizontally. Flashing at every opening and a proper drip at the base of the wall.
  • Humidity. Use a breathable penetrating sealer. Film-forming sealers trap vapour and blow off in sheets.

Choosing a face for a big elevation

The rule that matters: the bigger the wall, the more formats you need. A single face size across 2,000 square feet will show its mould repeat and once you notice it you'll never stop noticing it.

Our Rustic and Galarza ranges carry six or seven formats each for exactly this reason. On very large elevations, mixing two collections in bands is normal practice and looks deliberate rather than indecisive.

What it costs

Material $9 to $19 per square foot. Installed, budget $22 to $38 including prep, mortar, and sealer — the range depends far more on substrate condition than on which stone you chose. A sound block wall is at the bottom. Failed stucco that has to come off first is at the top.

Send elevations and we'll do a take-off free, including corner linear footage, which is the number people forget.

Common questions

What goes behind the stone on an exterior wall? +

Over block: a bonding agent and a scratch coat. Over framing: a weather-resistive barrier, then a second drainage layer, then metal lath mechanically fastened, then scratch coat. That second drainage layer is the one people skip and it's the one that causes the failures.

Does stone veneer meet Florida hurricane code? +

Adhered veneer over a properly built substrate is accepted throughout Miami-Dade and Broward. The stone isn't the engineered element — the wall behind it is. Your contractor pulls the permit against the wall assembly, not the finish.

How high can it go? +

There's no practical height limit for adhered veneer on a sound substrate. What changes above two storeys is access cost and the need for movement joints — on a tall elevation, thermal movement is real and the joints have to accommodate it.

Can I clad over existing stucco? +

Sometimes. If the stucco is sound, well bonded, and unpainted, lath can be fastened through it into the structure. If it's painted, cracked, or hollow-sounding, it comes off first. We'd rather tell you that now than get the call in two years.
