Quick answer: Cleaning is appropriate when the pavers are dirty but the existing coating is sound. Resealing may work when the old sealer is compatible, evenly worn, and free of whitening or peeling. Stripping is usually necessary when sealer is cloudy, milky, peeling, heavily blotched, over-applied, or trapping moisture.
Homeowners often use the words cleaning, resealing and restoration as though they describe the same job. They do not. Each service solves a different condition, and choosing the wrong one can waste money or make an existing coating failure harder to correct.
When professional cleaning may be enough
Cleaning is the least invasive option. It is appropriate when the pavers have organic buildup, surface dirt, irrigation residue or ordinary stains, but the existing sealer remains bonded and reasonably even. A cleaned surface may look dramatically better without receiving another coat.
Cleaning alone will not replace missing joint sand, restore a worn coating or correct trapped moisture. It also will not permanently stop algae from returning in shaded, damp areas. The goal is to remove contamination without unnecessarily damaging the paver surface or washing excessive material from the joints.
When a maintenance reseal may be appropriate
A maintenance reseal can be a good option when the previous coating is known, compatible and wearing evenly. The surface should not have widespread whitening, peeling, bubbling, heavy gloss buildup or soft areas. The pavers must also be thoroughly cleaned and dry enough for the selected product.
Before applying more sealer, a contractor should evaluate adhesion, moisture, drainage, joint condition and the type of coating already present. Applying a new product over an unknown or incompatible sealer can create bonding problems even when the surface initially looks acceptable.
When stripping is the safer restoration path
Stripping becomes more likely when the coating itself is the problem. Common warning signs include milky or cloudy areas, sheets of peeling sealer, dark puddled spots, uneven high gloss, trapped efflorescence, tire pickup or multiple incompatible layers.
Complete removal is more labor-intensive than cleaning or resealing because the old coating must be softened, removed and disposed of before the pavers can be prepared again. Some projects require more than one treatment. Results also depend on the sealer chemistry, coating thickness, paver porosity and how deeply the failed product has penetrated.
A practical diagnosis checklist
| Condition | Likely service | Reason |
|---|---|---|
| Dirt, algae or staining with sound coating | Cleaning | The contamination is on or near the surface. |
| Even fading with compatible bonded sealer | Maintenance reseal | The coating may be renewed after preparation and testing. |
| White, cloudy, peeling or heavily blotched coating | Stripping and restoration | Adding sealer may trap or magnify the failure. |
| Missing joint sand but no coating failure | Cleaning, sand correction and possible reseal | Joint condition must be corrected separately. |
Why an on-site inspection matters
Photographs can reveal obvious peeling or whitening, but they do not show everything. A reliable assessment may require checking multiple areas, identifying the existing finish, testing adhesion and looking for irrigation, drainage or moisture patterns.
HydroSeal evaluates whether the job can be handled as routine maintenance or needs a more extensive restoration. That distinction should be made before a quote is treated as final, because stripping a failed coating is fundamentally different from washing and applying another coat.

Frequently asked questions
Can cloudy pavers simply be resealed?
Usually not without diagnosis. If cloudiness comes from trapped moisture, coating failure or incompatibility, adding another coat can worsen the appearance.
Does every old sealer need to be stripped?
No. A compatible, bonded coating that is wearing evenly may be suitable for a maintenance reseal after proper cleaning, drying and testing.
Can pressure washing remove failed sealer?
Pressure washing may remove loose areas, but it rarely removes a bonded film evenly. Aggressive washing can also damage joints or leave an inconsistent surface.
