Paver Sealing in Jacksonville, FL

Paver Sealing in Jacksonville

Jacksonville's St. Johns River corridor keeps humidity elevated in riverside neighborhoods like Riverside, Avondale, and San Marco, where Gloeocapsa magma algae establishes on asphalt shingles within 18 months of installation on north-facing roof sections. Mandarin and San Jose have extensive older paver driveways from the 1990s and early 2000s that are well past the typical resealing interval. In Southside and Bartram Park, newer developments with paver hardscaping often lack a maintenance history because the homes are still on their first owners. Jacksonville's consolidated Duval County government means exterior contractor permits and inspections run through the City of Jacksonville Building Inspection Division rather than separate municipal offices.

In Northeast Florida's humid subtropical climate, unsealed pavers absorb water, UV radiation, and salt air constantly. The result is fading color, washed-out joint sand, and the kind of algae and mold growth that spreads fast once it gets a foothold. Paver sealing creates a protective barrier that slows all of it — restoring the original color, stabilizing the joints, and giving you a surface that's easier to clean and slower to stain.

The sealing process begins with a deep pressure wash to remove algae, mold, oil, and surface staining. Once the pavers are clean and fully dry — usually 24 to 48 hours depending on humidity — we re-sand the joints with polymeric sand rated for Florida's rainfall before applying sealer in two coats.

We use solvent-based and water-based options depending on the look you want. Solvent-based sealers give a wet, enhanced color and a slightly glossy finish. Water-based sealers are lower-sheen and better suited for travertine or light-colored pavers where the natural look matters more than pop. Both options are rated for Florida's UV index.

In St. Johns County's coastal zones, we typically recommend re-sealing every 2–3 years, though driveways with regular vehicle traffic and pool decks with heavy chemical exposure often benefit from resealing every 18 months. We'll tell you where your pavers land when we do the estimate.

Sealed pavers also hold joint sand longer — a practical point for anyone who has watched ants undermine a paver edge or weeds sprout from joints the season after a heavy rain. Polymeric joint sand hardens slightly when watered and resists erosion, which is why we always re-sand before sealing rather than skipping that step.

We are veteran-owned and operated, with over 8 years serving Northeast Florida homeowners. Our crew shows up on time, uses commercial-grade equipment, and doesn't leave until the job site is clean.
