If you own pavers on the Treasure Coast, sealing isn’t optional maintenance — it’s the difference between a driveway that looks new for a decade and one that’s faded, stained, and sprouting weeds in three years. Florida’s combination of intense UV, salt air, daily summer downpours, and warm humidity is close to a worst-case environment for unsealed concrete pavers.
Why sealing matters more in Florida than almost anywhere else
- UV fading. Unsealed pavers lose their color noticeably within 2–3 years of Florida sun. Sealer with UV inhibitors slows this dramatically.
- Mold, mildew and algae. Our humidity plus shaded, damp surfaces means black and green growth on unsealed pavers, especially on pool decks and north-facing driveways. Sealed surfaces give spores far less to grip.
- Salt air. Within a few miles of the Atlantic — which is most of the Treasure Coast — airborne salt slowly attacks the surface of unsealed concrete pavers.
- Joint sand washout. Summer storms flush the sand out of unsealed joints, which invites weeds, ants, and eventually shifting pavers. A joint-stabilizing sealer locks the sand in place.
- Stains. Oil drips, rust from patio furniture, tannins from oak leaves — sealed pavers wipe clean; unsealed pavers absorb.
What paver sealing costs on the Treasure Coast
Most Treasure Coast sealing jobs land between $1 and $2 per square foot, which includes pressure cleaning, re-sanding the joints, and two coats of sealer. A typical two-car paver driveway (600–800 sq ft) usually runs $700–$1,600; a pool deck is often similar. Prices vary with the condition of the pavers, whether old failing sealer has to be stripped first, and the type of sealer used. Stripping adds meaningful cost — which is one more reason not to let a cheap big-box sealer job go wrong first.
How a proper sealing job is done
- Pressure cleaning — removes dirt, mold, and old joint sand. On the Treasure Coast this often includes a mold treatment.
- Drying time — pavers must be fully dry; moisture trapped under sealer causes the cloudy white haze you see on bad jobs.
- Re-sanding — joints are refilled with clean sand, swept and compacted.
- Sealing — two coats of a quality acrylic or urethane sealer, applied when no rain is expected. In summer, scheduling around afternoon storms is half the skill.
How often should pavers be resealed here?
Every 2–3 years for driveways and pool decks in direct sun; high-end urethane sealers can stretch to 4–5. If water no longer beads on the surface, or the color looks flat when dry, it’s time.
Frequently asked questions
Can I seal pavers myself?
You can — but sealing is unforgiving. Trapped moisture, wrong product, or a coat applied before an afternoon storm produces hazing and peeling that costs more to strip than a professional job would have cost. It’s the classic project where doing it wrong once erases the savings of five DIY rounds.
My pavers turned white after sealing. What happened?
That haze is almost always moisture trapped under a solvent-based sealer, or a cheap sealer applied too thick. It’s fixable — a pro can strip and reseal — but it’s the most common failure we hear about from homeowners who hired the lowest bidder.
Should new pavers be sealed right away?
Most installers recommend waiting 30–90 days so efflorescence (the natural white salt bloom on new concrete pavers) can work itself out before you lock the surface.
