Paver Cleaning and Sealing in San Jose
Paver Sealing in San Jose: Revive Faded, Stained Pavers
Paver sealing in San Jose works best as the last step of a full clean, not a coat of sealer over dirty stone. First the surface is cleaned and the old joint sand, weeds and moss come out. Stains and white mineral deposits are treated. Then the joints are refilled with polymeric sand and the pavers are sealed, so the color stays rich and the joints stay put.
JPM Landscape has built and cared for interlocking pavers in San Jose since 1984. If your driveway, patio or walkway looks dull, stained or overgrown, this page explains what is going on and how we bring it back.
Why San Jose Pavers Get Dirty, Stained and Faded
Pavers are tough, but they are porous. Left unsealed, they soak up whatever lands on them, and our dry summers and wet winters keep working on the surface year after year.
Signs Your Pavers Need Cleaning and Sealing
- Dirty, dull or darkened surfaces that no longer look the way they did
- Oil, rust, leaf or food stains that have soaked in
- White powdery haze or streaks on the surface
- Weeds, moss or algae growing in the joints
- Faded, uneven or chalky color, especially in full sun
- Cloudy, white or peeling sealer
- Joint sand that has washed out, leaving open gaps
- Water that soaks in instead of beading up

What Causes It Around San Jose
Long, dry, UV-heavy summers fade pavers and break down sealer. Winter rain then washes sand out of the joints, and damp shaded corners grow moss and algae. Trees add to it, because leaves, sap and berries leave tannin stains that set in fast. Irrigation overspray leaves white deposits and rust-colored marks, and cars and grills drop oil and grease that soak straight into unsealed pavers.
Efflorescence is common on newer concrete pavers. Mineral salts travel to the surface with moisture and dry as a white powder, and it needs to be cleaned off before any sealer goes on.
When Sealing Is Not the Fix
Sealer protects a surface. It cannot hold up pavers that are moving. If stones are sunken, wobbly or shifting, the base underneath has a problem, and that needs paver repair before anything gets cleaned and sealed. Sinking is common in the Valley’s clay, which we explain in our guide to keeping pavers from sinking or shifting. If water is pooling on or running under your pavers, drainage may need attention first.
Paver Cleaning and Sealing Services in San Jose
Every surface gets the same careful approach: find out what is on the pavers, remove it without damaging the stone, then protect it. Here is what we do:
- Paver cleaning
- Paver pressure washing
- Paver stain removal
- Efflorescence removal
- Moss and weed removal
- Paver resealing
- Polymeric sand replacement
- Paver restoration
- Paver sealing
- Cloudy sealer removal
- Driveway paver sealing
- Patio paver sealing
We work on paver driveways, patios and walkways that we built and on ones we did not.
Different surfaces need different handling. A driveway carries tire marks, oil drips and heavy wear, so it gets stronger stain treatment and a sealer chosen to stand up to traffic. A patio sees food, grease and furniture marks, plus shade moss in damp corners. A pool deck needs a finish that keeps its grip when wet. We pick the cleaning method and the sealer to match, not one routine for every job.
Why We Clean and Seal Together
Sealing over dirt, stains or white deposits locks them in. Cleaning without sealing leaves the pores open, so the same stains and weeds return within a season or two. Doing both, in the right order, is what makes the result last.
What Makes the Result Last
The pressure has to be right, because too much strips joint sand and etches the surface. The pavers must be fully dry, since sealer applied over trapped moisture turns cloudy. Fresh, cured polymeric sand locks the pavers together and slows weeds and ants, and thin, even coats keep the sealer from turning hazy or peeling. Timing matters too: sealing needs a clean, dry stretch, usually late spring through early fall, so the sealer cures before winter rain.

Choosing a Sealer and Finish
Water-based sealers have low odor and lower VOCs, and many are breathable so moisture can escape. Solvent-based sealers give a deeper wet look but can be slicker and harder to reapply. Natural or matte finishes keep the stone’s look and better grip, while satin or wet-look finishes bring out richer color but can be slippery when wet, so we steer them away from pool decks and steps.
New Pavers and Older Pavers
New concrete pavers are not ready for sealer right away. They need time for moisture and mineral salts to work out of the stone, and sealing too early can cloud the surface. We tell you when your surface is ready, and we check for efflorescence before any sealer goes on.
Older pavers are a different story. After ten or fifteen years in the sun, many look chalky and tired, and the joints are often empty. A full clean, fresh polymeric sand and a new sealer coat can bring back much of the original color, which is why restoration is often the better move than replacement.
How Often to Reseal in San Jose
Most pavers do well with resealing every two to three years. Sun-baked driveways wear sealer faster and tend toward the short end, while shaded patios can stretch longer, though shade brings moss that needs watching. Resealing more often is not better, because stacked coats can turn hazy or peel. A quick water test tells you when the protection has worn thin: if a few drops soak in and darken the paver instead of beading up, it is time.
Our Process
- Inspect. We look at the surface, the joints, past sealer and any stains, and flag loose or sunken pavers.
- Clean. Pressure washing, plus targeted treatment for stains, moss and efflorescence.
- Remove old joint sand and weeds. Failed sand and plant growth come out of the joints.
- Dry. The surface must dry fully before anything goes on.
- Refill the joints. Polymeric sand is swept in and activated.
- Seal. Sealer is applied in even coats in the finish you choose.
- Cure and walkthrough. We tell you how long to keep off the surface and when to expect the full finish.
Because sealing depends on the weather, we plan around dry days and tell you if rain is likely to push the final step back.
What Affects the Cost of Paver Cleaning and Sealing in San Jose
Every surface is different, so we price after we see it. These are the factors that move the price most:
- Size of the area. Cost is based on square footage, so a patio and a full driveway are very different jobs.
- Condition of the pavers. Heavy moss, deep stains and efflorescence take more time than light dirt.
- Old sealer. Failed or cloudy sealer has to come off before new sealer goes on.
- Joint sand. Joints that need a full re-sand take more material and labor.
- Sealer and finish. Sealer type and finish change the material cost.
- Access. Tight side yards and long hose runs add time.
- Repairs. Loose or sunken pavers are fixed first and priced separately.
After an on-site evaluation, you get a clear estimate based on your property’s needs, and you will know what the job involves before it starts.

Paver Cleaning and Sealing FAQs
Most pavers do well with resealing every two to three years. Sunny driveways lean toward two, and shaded patios can go a little longer. A quick water test tells you when sealer has worn thin.
It is usually efflorescence, which is mineral salt that rises to the surface with moisture. It should be cleaned off and the pavers dried fully before sealing, because sealer over it locks the haze in.
You can, but too much pressure strips the joint sand and can etch the surface. Washing is also only the first step, since the joints need fresh sand and the surface needs sealer afterward.
Usually yes, but the failed sealer has to be removed first. New sealer over a cloudy or peeling coat will not bond well and tends to look worse than before.
Most sealers allow light foot traffic within about a day and vehicles after a few days. The exact time depends on the product and the weather, and we will tell you before we leave.
Yes, if any are sunken, loose or cracked. Sealer will not fix a failed base, so we level and reset problem areas first and then clean and seal the whole surface.
Get Your Pavers Cleaned and Sealed Before the Rainy Season
Every winter, rain washes sand out of the joints and feeds moss, algae and stains on unsealed pavers. Cleaning and sealing them in the dry months restores their color, locks the joints in place and protects the surface through the wet season.
