Paver Cleaning and Sealing: What to Expect, Step by Step

A good visit starts with a quick look at the surface. The technician checks for sunken spots, loose stones, deep stains and how much joint sand is left, because cleaning will not fix structural problems. If a few pavers need to be reset, it makes sense to handle that before sealing so you are not sealing over a defect.

Next comes prep. Furniture, planters and grills are moved, nearby plants may be wet down to protect them, and doors, screens and pool equipment are noted so the crew can avoid blasting water where it should not go. On a pool deck inside a screen enclosure, extra care is taken around the screen frames and the pool itself.

Most professional paver cleaning uses a pressure washer connected to a rotary surface cleaner, which looks like a round disc that glides across the pavers. It cleans evenly without the zebra stripes that a handheld wand often leaves, and it is much gentler on the joints than blasting with a narrow tip.

Black algae, mildew and organic stains may get a pre-treatment so they lift more completely. Oil spots, rust from well water irrigation and efflorescence (the white chalky haze some pavers develop) may need specific cleaners. Not every stain comes out completely, especially old oil that has soaked deep into the stone, so ask for an honest expectation before work starts.

Cleaning inevitably flushes out loose sand from the joints, which is expected. It also exposes how much sand had already been lost to rain and ants.

Before new sand or sealer goes down, the pavers need to dry. In Central Florida that can be a few hours on a sunny morning or longer on a humid or overcast day. Sealing damp pavers can trap moisture and leave a cloudy, milky look, so a careful crew will not rush this step.

Once dry, joints are refilled with sand, often polymeric sand that firms up when activated with water. Full joints lock the pavers together, help stop shifting, and make it harder for weeds and ants to move in.

The sealer is usually sprayed or rolled on in one or two coats. There are a few general types. Some sealers soak into the stone and leave a natural matte look. Others leave a satin or wet look finish that deepens and brightens the color. Some are water based and some are solvent based, and each has tradeoffs in shine, slip resistance and how long it lasts.

For pool decks, slip resistance matters, so a natural or low sheen finish is often the safer choice for wet bare feet. Travertine pool decks are a special case: they are porous and stay cool underfoot, and they usually need a sealer made for natural stone rather than one designed for concrete pavers.

A quality sealer helps hold the joint sand in place, resists stains, slows algae growth and reduces fading from UV, which is a big deal under the Florida sun.

Expect to keep foot traffic off for several hours and vehicles off a sealed driveway for longer, often a day or more depending on the product and weather. Your technician should give you specific times. Afternoon thunderstorms are the main risk in summer, so crews often seal early in the day and watch the radar.

Irrigation is worth planning for too. Turn off sprinklers that hit the pavers until the sealer has cured, then adjust heads so they do not spray directly on the surface every day, which feeds algae and leaves mineral stains.

Many Central Florida homeowners clean and reseal every two to three years, with a lighter cleaning in between if algae builds up in shaded spots or around the pool. Driveways that see a lot of traffic, pool decks with heavy splash and areas under trees may need attention more often.

Pricing depends on square footage, how dirty the surface is, how much sand is needed and the sealer chosen. As a broad market reference, combined cleaning and sealing in the region often falls somewhere around 1.50 to 3.50 dollars per square foot, with heavy stain removal, travertine or small detailed areas sometimes costing more.
