Sealing your own pavers runs roughly $0.25 to $0.75 per square foot in materials, plus a weekend of your time. Hiring it out typically costs $1.00 to $3.00 per square foot all-in, and takes a few hours. The real difference isn’t the sealer itself — it’s what happens if the surface wasn’t fully clean, the joint sand hadn’t cured, or the wrong sealer went on the wrong paver type. Get that part wrong and a $200 DIY project turns into a $1,000+ strip-and-reseal.
Here’s how the two routes actually compare for a San Jose patio or driveway, and how to tell which one fits your yard.
If your pavers are cracking, sinking, or shifting, sealing won’t fix that — that’s a repair issue first. For sealing and joint stabilization on pavers that are otherwise in good shape, this is the process our paver cleaning and sealing service uses on Bay Area patios and driveways.
Most San Jose homeowners land in one of two camps. A simple patio under roughly 300 square feet, in decent shape, with a free weekend and no rush, is a reasonable DIY candidate. A driveway, pool deck, or any surface where the existing sealant type is unknown is where professional sealing earns its cost — the wrong sealer applied over an incompatible existing coat can trap moisture and turn cloudy or hazy, a repair that costs more than the original job.
J&P Landscape has sealed and maintained pavers across San Jose and the wider Bay Area since 1984, and the pattern holds across nearly every property: the failures we get called to fix almost never come from a bad sealer. They come from skipping prep, rushing the timing, or guessing at the product.
What DIY Paver Sealing Actually Takes
A DIY sealing job breaks into three stages, and each one has a way to go wrong.
Cleaning and Drying the Surface
- Power-wash off dirt, moss, and old sealant residue, treat any oil or rust stains separately, and pull weeds from the joints. Then give it 24 to 48 hours of dry weather before sealing.
- Seal over a damp or dirty surface and moisture gets trapped underneath. That shows up later as a hazy, milky finish that usually means stripping the whole job and starting over.
Letting Fresh Joint Sand Cure
If the joints need fresh sand, that has to go in and cure before sealing — sealing too soon locks in loose or unstable joints instead of protecting them.
Applying polymeric sand, letting it set, and confirming it’s fully cured typically adds a full extra day to the timeline.
Applying the Sealer
Apply in thin, even coats with a roller or pump sprayer, working in sections and avoiding puddling at the edges. Overspray on nearby plants and lawn is a real risk on a windy day.
Picking a high-gloss “wet look” sealer for a pool deck or entry walkway can also make the surface noticeably more slippery when wet — matte and low-sheen formulas are the safer call for anywhere bare feet or rain are involved.
What to Budget For
Materials for an average job run about $0.25 to $0.75 per square foot, and a basic sprayer, roller, and edging tools are another $100 to $300 as a one-time cost. Budget a full weekend if the joints are already in good shape, or closer to three days if resanding comes first.
What a Professional Paver Sealing Job Includes
The value in hiring it out isn’t really the application — a competent DIYer can put sealer on a surface. It’s everything that happens before the sprayer comes out.
What Expertise Actually Prevents
That starts with correctly identifying the paver material — concrete, clay brick, and natural stone all have different porosity and need different sealer chemistry — and figuring out what’s already on the surface from a prior sealing job.
Layering an incompatible sealer over an old one is one of the most common causes of the cloudy, blotchy look homeowners bring to us after a DIY reseal gone wrong, and it’s hard to diagnose without testing. A crew also brings commercial-grade sprayers for even coverage on larger surfaces, and carries the insurance and workmanship guarantee that a homeowner doing it themselves doesn’t have.
The same crews who handle paver installation know these products inside out — you can see completed work in our interlocking paver projects around San Jose, and if you’re weighing a fresh install over resealing older pavers, that’s covered separately there.
Checking the License
Any Bay Area company doing paver work, sealing included, should be able to show a current California contractor license.
J&P Landscape has held CA License #963784 since 1984 — 40+ years serving San Jose and the wider Bay Area — and we’re happy to show it before any job starts.
Cost Comparison: DIY vs. Professional Paver Sealing
| Factor | DIY | Professional |
|---|---|---|
| Cost per sq ft | $0.25–$0.75 (materials only) | $1.00–$3.00 (all-in) |
| Time (300 sq ft patio) | A weekend; 3 days if resanding first | A few hours to one day |
| Equipment | $100–$300 one-time (sprayer, roller, edging tools) | Included |
| Surface & sealant diagnosis | On you — misjudging paver type or old sealant is the top failure point | Included |
| Warranty | None | Typically included |
| Best fit for | Small, simple patios in good condition, with a dry weekend to spare | Driveways, pool decks, multi-surface properties, or any unknown existing sealant |
Ranges reflect typical Bay Area pricing as of September 2026 and will vary with paver material, surface condition, and access.
Which Option Fits Your San Jose Yard
Two practical things narrow the decision fast.
Size and Complexity
A small, single-surface patio in good repair is forgiving of a DIY learning curve. A driveway, a pool deck, or a property with pavers in several different areas raises the cost of a mistake fast.
Timing the Job Right
San Jose’s realistic sealing window is the dry stretch from roughly May through October, since the sealer needs 24 to 48 hours of dry weather on both ends.
Outside that window, DIY and professional crews are working around the same rain risk — the difference is a pro can usually read a five-day forecast and schedule around it, where a homeowner is often working around whatever weekend is free.
If you’re unsure which category your yard falls into, that’s usually the sign to get a second opinion before buying sealer.
Ready for Pavers That Actually Hold Up to Bay Area Weather?
A first-time patio seal or a driveway resealing that’s overdue — either way, getting the surface, timing, and product right the first time saves a redo later. J&P Landscape has served San Jose, Silicon Valley, and the wider Bay Area since 1984, and we’re happy to take a look at your pavers and tell you honestly whether DIY is reasonable for your yard or whether it’s worth having us handle it.

Frequently Asked Questions
Most Bay Area pavers need a fresh coat every 2 to 3 years, depending on the paver material, sun exposure, and how much foot or vehicle traffic the surface sees. Homes with heavy shade or steady winter rain exposure tend toward the shorter end of that range.
Both are workable. A small, simple patio in good condition is reasonable to DIY. Driveways, pool decks, or any surface where you're not sure what sealer was used last time carry enough risk of a botched, hazy finish that professional sealing usually pays for itself.
Give new polymeric sand time to fully cure before sealing — rushing this step is one of the most common reasons a fresh seal job fails early. If you're not sure the sand has cured, that's worth confirming before applying anything.
A wet-look sealer adds shine and deepens paver color; a matte sealer protects without changing the look much and stays less slippery when wet. Pool decks, entries, and walkways generally do better with matte or low-sheen formulas.
For most Bay Area patios and driveways, yes. It locks joint sand in place, resists stains and weeds, and protects paver color from UV fading, at a fraction of the cost of a future repair.
Yes. J&P Landscape serves San Jose, Silicon Valley, and the wider Bay Area, including Redwood City, Fremont, and surrounding communities, for paver sealing and the rest of our hardscaping work.
