Paver Sealing

Cleaning pavers gets rid of surface dirt and growth, but sealing is a separate step that actually protects the surface going forward — an unsealed paver stays porous and will simply reload with the same staining and weeds within a season or two.

What paver sealing actually involves, step by step

Surface material check. Stamped, colored, or sealed concrete is identified separately from plain broom-finish concrete before pressure is applied, since a sealed or decorative surface can discolor or lose its finish under the pressure setting that plain concrete tolerates without issue.

We also handle Restaurant Exterior Washing and School Building Washing for Spartanburg properties.

Detergent application. A degreasing or stain-lifting solution is applied to oil spots, tire marks, and organic staining and left to dwell, since pressure alone tends to spread an oil stain outward into the surrounding concrete rather than actually lifting it out of the pores.

Surface cleaning pass. The surface is cleaned in overlapping passes with a surface cleaner attachment held at a consistent distance and angle, which produces an even result across the slab instead of the ringed or striped pattern a handheld wand leaves on a large flat area.

Edge and joint detail. Expansion joints, edges along garden beds, and corners the surface cleaner can't reach are finished separately at a lower pressure, since those areas are also where a wand held too close is most likely to etch a visible line into the concrete.

Rinse and runoff containment. The area is given a final clear-water rinse, and runoff containing detergent or lifted contaminants is directed away from storm drains and planting beds rather than left to flow wherever the slope of the driveway happens to take it.

How to tell paver sealing is needed

Concrete and hardscape buildup shows up in a handful of specific, checkable ways rather than as one general dirty look. Dark stains from oil, tires, or rust that don't fade at all after repeated rain, and instead seem to spread slightly at the edges over time, are the kind of staining plain water was never going to remove on its own. A surface that feels noticeably slick specifically when wet, beyond what plain wet concrete normally feels like, usually means an algae or mildew film has built up, since that film is what actually creates the slipperiness.

A green or black tinge concentrated in shaded corners or low spots where water tends to pool after rain is that same growth getting a head start in the areas that stay damp longest. And a white, powdery haze on the surface — sometimes mistaken for a light coat of dust — is a mineral deposit called efflorescence, which is a different problem from ordinary dirt and needs a different approach to treat.

What goes wrong when paver sealing is done badly

Etching and striping from a close wand. Holding a pressure washer tip too close to bare concrete, or moving it too slowly, can etch a visible line or swirl pattern directly into the surface — a mark that doesn't wash out because it's physical erosion of the top layer of the slab, not dirt.

Discoloring sealed or stamped concrete. Sealed and stamped decorative concrete can lose its sheen or develop a blotchy, uneven look when cleaned at the same pressure used on plain broom-finish concrete, since the sealer layer itself is thinner and softer than the concrete underneath it.

Spreading oil stains instead of lifting them. Blasting an oil or grease stain with straight pressure and no chemical pre-treatment tends to push the stain outward into the surrounding pores of the concrete, turning a contained spot into a much larger faded halo that's harder to treat afterward.

What keeps the problem from coming back

Whether a driveway or patio stays clean longer after a wash comes down to what's allowed to soak into the surface afterward. A penetrating or film-forming sealer applied right after cleaning fills the pores that algae, oil, and organic stains would otherwise work their way into, and it's the single biggest factor in how much longer the surface actually stays clean. Sweeping the surface on a routine basis, rather than letting leaves and clippings sit and decompose, keeps organic material from building into the kind of set-in staining that needs professional treatment later.

A fresh oil or fluid drip wiped up or treated with an absorbent within a day sets far less deeply into the concrete's pores than the same drip left for weeks, which makes prompt cleanup more effective than any amount of pressure applied afterward. And a low spot that holds standing water after every rain gives algae and mildew a head start that a flat, well-draining surface doesn't, so improving drainage there specifically reduces staining in that exact spot rather than across the whole slab.

How to choose who does paver sealing

Does the quote specify the PSI and method — pressure wash vs. soft wash — for each surface? The wrong PSI on siding, roofing, or wood can cause damage, so the method should be disclosed per surface, not left as one generic number. Is a written scope listing every surface included — driveway, siding, deck, roof, fencing — provided? Bundled pricing sometimes covers only one or two surfaces despite sounding comprehensive. Are the cleaning chemicals used, and their effect on nearby landscaping and pets, disclosed before the job? Soft-wash detergents vary in strength, and runoff can affect plants or pets nearby. Does the estimate distinguish concrete or driveway work from roof or siding work? Roof and siding washing typically require lower pressure and different technique than concrete, and pricing that lumps them together can hide risk. What is the policy if pressure washing reveals pre-existing damage, like cracked paint or loose mortar? Pre-existing conditions can surface once dirt is removed, so it helps to know how that gets handled before agreeing to the job. Is post-treatment sealing for driveways or decks included in the price or billed separately? Sealing is often an add-on, not part of a basic wash.

No mention of PSI or method — pressure vs. soft wash — for each surface. The wrong pressure on siding, roofing, or wood can cause real damage, and a quote that has not specified method per surface has not actually assessed the job. A price far below every comparable bid for the same square footage. An unusually low price can mean lower-grade equipment, no pre-treatment chemical, or rushed coverage that leaves streaking. No mention of what chemicals are used or their effect on landscaping. Undisclosed chemical strength is how plants and grass near the work area end up damaged. Full payment demanded before the job starts. Paying in full upfront removes leverage if streaking, missed spots, or damage shows up afterward. Pressure to add extra services on the spot without a separate written price. Add-ons proposed in the moment are harder to compare against other bids.
