Paver Sealing and Maintenance: A Season-by-Season Care Guide
Healthy pavers need little but regular attention. This guide covers routine care for a surface that is in good shape — when to clean, top up joints and seal. Problems such as settling or spreading edges are covered in paver repair and restoration.
A care calendar
-
Spring
Check after winter
Sweep up sand, grit and de-icer residue; look for units that lifted or sank and joints that emptied.
-
Summer
Clean and refill
Remove weeds and moss, treat stains, refill joints in dry weather; seal now if you are sealing.
-
Fall
Prepare for frost
Clear leaves before they stain and block drainage; top up joints; fix low spots before they freeze.
-
Winter
Clear snow early
Shovel promptly, go easy on de-icers and use sand for traction — see winter care.
Winter detail, including the de-icer disagreement, is in winter paver care.
How often — what sources say
| Task | Published interval | Why it varies |
|---|---|---|
| Sweep and inspect | Regularly; inspect at least spring and fall (one guide) or annually (another) | Catch low spots and empty joints early |
| Top up regular joint sand | About every 1–3 years | Washes out; weeds and ants follow |
| Re-sand with polymeric sand | About 3–10, 5–10 or 8–15 years, depending on the source | Traffic, weather and installation quality drive the spread |
| Seal (if you seal) | Every 1–3, 2–3 or 3 years by source; optional for some products | Depends on sealer type, sun and traffic |

Cleaning without damage
- Sweep and rinse as routine; a stiff broom and a garden hose handle most dirt.
- Pressure: use a low setting or a rotary surface cleaner; high pressure strips joint sand and can etch the surface.
- Stains: oil, rust, leaf tannin, mold and efflorescence each need a different cleaner — treat each stain before a general wash.
- Efflorescence: the white haze on new pavers usually fades on its own; do not seal over it.
- Joints: refill any joints the cleaning disturbed, in dry weather.
To seal or not to seal
Reasons people seal
- Water beads off instead of soaking in
- Better resistance to stains
- Can enhance or hold color
Reasons to hold off
- Optional for some interlocking products
- Changes traction, especially when wet
- Needs repeating, and costs each time
If you do seal:
- Use the sealer the paver manufacturer approves; finishes range from matte to high-gloss.
- On new pavers, wait — one guide says about 30 days — so efflorescence can clear and joints can cure.
- After polymeric sand, a technical guide says to wait 24–48 hours after it cures before sealing.
- Keep foot traffic off for the cure time: about 24–48 hours for water-based and up to 72 hours for solvent-based products, per guides.
- Check wet traction on a small area first; no finish removes slip risk.
One Chicago-area guide prices professional sealing at $300–$600 per service; no Faribault price is known.
When care becomes repair
Sealing and sanding cannot level a dip or stop edges from spreading. If units are sinking, rocking or creeping outward, or water is ponding, the cause is usually underneath — see the diagnosis table in paver repair and restoration.
Care questions
Does sealing make pavers last longer?
Sealer makes water bead off rather than soak in, which some sources link to less freeze–thaw damage, and it can help resist stains and fading. Other sources treat sealing as optional for interlocking concrete pavers. Follow the paver manufacturer’s guidance for your product.
Can I pressure wash pavers?
Only gently. High pressure strips joint sand and can etch the surface; guides recommend a low setting or a rotary surface cleaner, then refilling any joints that were disturbed.
