Paver joints lose their sand to rain and foot traffic season after season, and once the sand is gone, weeds root in the gaps and the pavers start to shift and rock underfoot. Cleveland Pressure Washing cleans the surface first, then reseals the joints — a service backed by a 4.9-star rating from 28 Google reviews.
A paver patio or walkway that looks dull and uneven usually isn't a paver problem — it's a joint problem. Sand washes out a little at a time, and once enough is gone the pavers lose the interlock that keeps them level, which is why a patio that was flat two summers ago starts rocking underfoot.
Sealing after cleaning is what actually slows that process down. It isn't a cosmetic step tacked onto the wash — the sealer locks the joint sand in place and cuts down on the efflorescence, that white, chalky bloom that shows up on darker pavers left unsealed.
Why do the joints between my pavers keep disappearing?
Every rain event moves a small amount of the sand between pavers, and normal foot traffic works the rest loose over time. Left alone long enough, the gaps widen enough for weeds and ants to move in, and the pavers themselves lose the lateral support that keeps a patio flat instead of wavy.
What does cleaning and sealing actually involve?
The surface gets washed first to strip out algae, mildew, and the loose debris sitting in the joints, then it's left to dry fully before sealer goes down — sealing over a damp surface traps moisture underneath and causes cloudiness later.
Cleveland Pressure Washing handles both steps as one job rather than two separate visits, and covers the work across 20 service areas around Cleveland, OH.
Is that white haze on my pavers something to worry about?
That's efflorescence — mineral salts pulled to the surface as moisture evaporates out of the paver. It's cosmetic, not structural, but a sealer coat is what keeps it from reappearing once it's been cleaned off.
How soon can I walk on the pavers after sealing?
The sealer needs to dry fully before regular foot traffic returns. The crew will give you the exact window on the day, since it depends on the product used and the weather at the time.
Do you have to reseal every year?
No — sealed joints hold up for multiple seasons before they need another coat. How long depends on how much foot and vehicle traffic the pavers see, and how much direct sun and rain they take.
Does sealing change the color of the pavers?
A wet-look sealer darkens the surface and adds sheen; a natural-look sealer protects without changing the appearance. Which one to use is worth deciding before the job, not after.
