Washing cleans pavers — and exposes them
A professional wash makes a paver driveway or patio look dramatically better. But washing does two things at once: it removes the grime, and it loosens some of the joint sand — the sand packed between pavers that locks them in place. That is normal and expected. It is also exactly why sealing after washing is not an upsell — it is the second half of the job.
What joint sand does
Pavers are individual pieces, and joint sand is what keeps them from shifting, rocking, and spreading. It also blocks weeds from rooting between pavers and keeps ants from tunneling underneath. When washing blasts some of it out, the joints are left shallow and vulnerable. Re-sanding and then sealing locks everything back in — tighter than before, because the sealer binds the sand in place.
What sealer actually does
A quality paver sealer does four jobs. It locks the joint sand so future washes and Florida downpours do not wash it out again. It blocks stains — oil drips, rust, leaf tannins, and tire marks sit on top of the sealer instead of soaking into the paver. It slows weed and ant growth by hardening the joints. And it deepens the color, giving pavers that rich, wet look that makes a driveway look brand new. It does not make pavers waterproof or indestructible — but it makes them far easier to live with.
Timing: wash, dry, sand, seal
Order and timing matter. First, the wash — a deep clean that removes grime, algae, and old failed sealer. Our paver sealing prep wash is designed exactly for this: clean enough for sealer to bond, gentle enough to protect the pavers. Then drying — pavers must be fully dry before sealing, usually 24 to 48 hours in Florida sun. Sealing damp pavers traps moisture and turns the finish cloudy white. Then re-sanding — fresh sand swept and compacted into the joints. Then the sealer, applied evenly and allowed to cure. Rushing any step shortens the life of the whole job.
What sealing cannot do
Honest expectations: sealer will not fix sunken or uneven pavers — that is a base problem needing re-leveling. It will not hide deep oil stains that soaked in years ago, though it prevents new ones. It will not make a slippery surface safe — in fact, some glossy sealers can make wet pavers slicker, so anti-slip additive matters around pools. And no sealer lasts forever in Florida sun (see below).
How long sealer lasts in Florida
Florida is brutal on sealer — intense UV, daily rain, and heat break it down faster than in milder climates. A quality job typically lasts two to three years on a driveway, a bit longer on a shaded patio. You will know it is wearing off when water stops beading on the surface and stains start soaking in again instead of sitting on top. Re-sealing on schedule is much cheaper than letting pavers go unprotected for years and then needing restoration.
Washing sealed pavers later
Once sealed, your pavers are easier to maintain — but tell any future wash company the pavers are sealed. Sealed pavers should be washed at moderate pressure, not blasted, or the sealer gets stripped prematurely. A professional driveway and concrete cleaning crew adjusts technique for sealed surfaces. With sealer intact, routine washes are quicker and cheaper because grime never gets a deep grip.
The cost logic
Sealing adds to the project cost — there is no point pretending otherwise. But compare it to the alternative: unsealed pavers that stain permanently, grow weeds in every joint, shift and settle, and need aggressive restoration every few years. Sealing after washing protects the money you just spent on the wash and stretches the years between major work. Most homeowners who seal once never go back to bare pavers.

Frequently asked questions
Do I have to seal my pavers after pressure washing?
You do not have to, but it is strongly recommended. Washing removes grime and loosens joint sand; sealing replaces that protection, locks the sand in, and keeps stains from soaking in. Skipping it leaves freshly cleaned pavers exposed to Florida's sun and rain.
How long after washing should I wait to seal?
Until the pavers are fully dry — typically 24 to 48 hours in Florida weather. Sealing damp pavers traps moisture under the sealer and causes a cloudy white finish. A professional will check dryness, not just the clock.
Will sealer make my pool deck slippery?
Some glossy sealers can. Around pools, always use a sealer with an anti-slip additive mixed in — it adds invisible grip without changing the look. Mention the pool when discussing sealer options so the right product is used.
Can you seal over old sealer?
Sometimes. If the old sealer is intact and just worn, a new coat can go over it after proper cleaning. If it is peeling, flaking, or whitened, it usually needs to be stripped first — which is a bigger job. A pro can tell by looking.
How often do pavers need re-sealing in Florida?
Every two to three years for driveways is typical in our climate; shaded patios can stretch a bit longer. When water stops beading on the surface, the sealer is wearing thin and it is time to plan the next round.
