Stone carpet in South Florida runs about $8 to 14 per sq ft installed, with base preparation, crack treatment, priming and a 2 year workmanship warranty included in that rate. Marble chip builds sit at the lower end of the range and river pebble builds at the upper end. Aggregate size, slab condition, access and total area move the rate within the band, and only a site measurement fixes the final number.
Price is usually the first question on a decorative surface. This page breaks down what sits inside the per sq ft rate for stone carpet, what pushes it up or down, and how it compares against the other ways to redo a Florida deck.
A stone carpet rate has 2 parts, the material and the labor to install it. Quoted per square foot the 2 are bundled together, and on a typical residential deck the split runs roughly 40 percent material to 60 percent labor.
That ratio explains most of what follows. Anything that slows a crew down moves the rate more than the choice of stone does.
Material cost tracks the aggregate first.
The binder is the other material line. An aliphatic polyurethane resin costs more than an aromatic one and is the only sensible choice outdoors in Florida, because it resists UV and does not yellow. Saving money there is the most expensive decision available on this job.
Installed stone carpet across Broward, Miami-Dade and Palm Beach runs $8 to 14 per sq ft.
That rate covers base preparation, crack routing and treatment, priming, mixing and troweling the aggregate, edge and transition detailing, and cleanup afterward. The site visit and measurement are free, and a 2 year workmanship warranty is included.
What it does not cover is structural repair of a failed slab, new drainage, or demolition of an existing surface that has to come off first. Those are quoted as separate lines once the deck has been seen.
6 things account for nearly all of the movement inside the range.
Installed rates for the common South Florida alternatives, all per square foot.
| Surface | Installed rate per sq ft | Service life |
| Stone carpet | $8 to 14 | 10 to 15 years |
| Poured rubber deck | from $8 | 10 to 15 years |
| Demolition and new pavers | $25 to 40 | 15 to 25 years |
| Thin roll on deck coating | $2 to 6 | 1 to 3 years |
The coating line is the one that misleads people. At $2 to 6 per sq ft it looks like the obvious answer until it starts peeling, and 3 recoats inside 6 years costs more per square foot than doing the job once.
Stone carpet sits in the middle of the group and carries no ongoing repair or resealing cost. Spread across a 10 to 15 year life, its cost per square foot per year is usually the lowest of the 4.
2 numbers set the rate, the square footage and the condition of the slab.
Measure the area in square feet, taking length by width for each section and adding the sections together. Measure stairs and treads separately, since they carry noticeably more labor per square foot than open deck.
Then look hard at the slab. Hairline cracking is normal and gets treated during preparation. Spalling, active movement, hollow sounding patches or water that stands after rain all mean the base needs work before any surface goes down, and that changes the number.
Multiply your square footage by the range above for a planning figure, then confirm it against a written quote taken from an on site measurement. A free Deck Check settles both the footage and the slab condition in about 30 minutes.
