Concrete cleaning and sealing services cost $1 to $3 per square foot installed on average, or $575 to $1,700 for a 2-car concrete driveway, according to HomeGuide (updated November 2025)1. HomeAdvisor and Angi – corporate siblings publishing matching figures, which alone do not establish independent corroboration – put the national average at $1,500 per project, at $1.35 to $2.50 per square foot with labor included, or $0.10 to $0.75 per square foot for materials alone (updated June and October 2026)23. HomeAdvisor's page states two conflicting total project ranges ($1,350 to $3,500 and $850 to $7,000), so both ranges are excluded here; Angi publishes $1,350 to $3,500. The per-square-foot ranges diverge across publishers, and no conclusion about which applies follows from the differences; each figure is labeled with its publisher and date throughout this guide.

Cost by sealer type
HomeGuide's figures by sealer type (2025)1:
| Sealer type | HomeGuide materials per gallon (2025) | HomeGuide installed per sq ft (2025) |
|---|---|---|
| Acrylic | $30 – $60 | $1.00 – $2.00 |

HomeAdvisor and Angi publish an identical per-gallon table covering three types (2026, matching figures, corporate siblings): acrylic at $16 to $75, polyurethane at $25 to $110, and epoxy at $40 to $17523. Their gallon figures diverge from HomeGuide's for every type, and no conclusion about which applies follows from the differences. Angi also reports sealer materials averaging $20 to $60 per gallon across types (2026)3. HomeGuide's materials-plus-labor breakdown for acrylic and polyurethane sealers: sealer material at $0.30 to $1.75 per square foot and labor at $0.70 to $1.25 per square foot, totaling $1.00 to $3.00 installed (2025)1.
Labor, prep, and related costs
- Labor. HomeGuide puts labor at $0.70 to $1.25 per square foot including basic cleaning and prep (2025)1; Angi puts labor at $1.25 to $1.75 per square foot not including repairs (2026)3 – separately published figures that diverge, with no conclusion about which applies.
- Cleaning and prep. Pressure washing at $0.35 to $0.75 per square foot (HomeGuide, 2025)1. Angi quotes expert reviewer Matt DiBara putting cleaning and surface preparation for concrete at least a year old at $1 to $1.75 per square foot (2026)3.
- Removing existing sealant. $1 to $3 per square foot (Angi, 2026)3.
- Repairs before sealing. Driveway repair at $100 to $400 for small cracks, concrete resurfacing at $3 to $7 per square foot, mudjacking at $4 to $9 per square foot, and concrete driveway replacement at $6 to $15 per square foot (HomeGuide, 2025)1. Angi's resurfacing figure of $60 per square foot is excluded here because it conflicts with its own nearby figures and could not be verified.
- Decorative finishes. Concrete stamping at $8 to $19 per square foot installed, concrete staining at $3 to $15 per square foot, and colored concrete at $4 to $15 per square foot (HomeGuide, 2025)1. Angi puts staining at $2 to $6 per square foot, polishing at $3 to $8 per square foot, and stenciling at $9 to $20 per square foot (2026)3 – separately published figures that diverge on staining, with no conclusion about which applies.
Hiring a concrete sealing contractor
HomeGuide recommends getting at least three estimates, choosing a licensed, bonded, and insured company with five or more years of experience, getting the contract and detailed estimate in writing before work starts, and not making the final payment until the work is complete (2025)1. For product selection, coat count, and application requirements, follow the exact product's manufacturer instructions.
