Paver sealing cost calculator
Sealing is three jobs sold as one, and the failures almost always trace to collapsing them. Clean is one line. Re-sanding the joints is a second. Sealing is a third, and it cannot start until the pavers are genuinely dry all the way through. Price the sealing line here, then add the cleaning line from its own band.

Detergent: Two coats, cure window. This is a planning band, not a survey figure: measure the site and price your own labour.

The three lines
| Line | $/sq ft | Day | Gate before starting |
|---|---|---|---|
| Clean and strip old sealer | 0.30–0.55 | 1 | Weather window |
| Re-sand joints (polymeric) | 0.35–0.70 | 1–2 | Surface dry, joints dry |
| Seal, two coats | 0.90–1.90 | 2–3 | 24–48 h dry, no rain forecast |
Re-sanding is charged from its own band and is not in this calculator’s output; the seal line is. Quote all three or none.
What ruins a seal job
- Trapped moisture. Seal over damp pavers and the film goes milky. That is a strip-and-redo, on you.
- Efflorescence not dealt with. The white bloom comes back under the sealer and cannot be reached.
- Blasting the joint sand out. A zero-degree tip in a joint empties it in a second and the pavers move.
- One heavy coat instead of two thin ones. Puddles, gloss banding, and a surface that peels.
Surface damage risk
Cure, not dry
Worked example
A 600 sq ft paver patio, moderate condition, easy access. The seal line alone at $0.90–$1.90 gives $540–$1,140. Add cleaning at $0.30–$0.55 ($180–$330) and re-sanding, and the honest whole-job number is roughly $930–$1,890 across three visits.
