Cost to seal a concrete driveway
The cost to seal a 2-car concrete driveway is $575 to $1,700 on average or up to $5,200 when using epoxy or polyaspartic sealers. More expensive sealers are best for stamped concrete drives. Concrete sealers won’t fill cracks, so extra fees apply to repair the surface before applying the sealant.
| Size | Square feet | Average cost* (acrylic or polyurethane) | Average cost* (epoxy or polyaspartic) |
|---|---|---|---|
| 1-Car driveway (12’x24’) | 288 | $290 – $850 | $850 – $2,600 |
| 2-Car driveway (24’x24’) | 576 | $575 – $1,700 | $1,700 – $5,200 |
| 3-Car driveway (24’x36’) | 864 | $850 – $2,600 | $2,600 – $7,800 |

Cost to seal a concrete garage floor
The cost to seal a 360-square-foot concrete garage floor is $360 to $1,080 on average. Penetrating sealers with siloxane or silicates resist stains and look natural. Epoxy and polyaspartic coatings are the most durable and attractive for interior floors but cost up to 3 times more.
Cost to seal a concrete patio
The average cost to seal a 10’x20’ size concrete patio is $250 to $600. Concrete patios and steps will crack if not sealed. The best sealers for a patio are polyurethane or a penetrating sealer for a matte finish. For high-traffic patios, pay extra for epoxy and avoid acrylics.

Concrete sealing FAQs
Is concrete sealing worth it?
Concrete sealing is worth it for the following reasons:
Adds a protective barrier surface on top of the concrete
Prevents cracks and stains
Adds scratch resistance
Protects against color fading from the sun
Repels all moisture
Makes it easier to clean up stains
Prevents falls with non-slip textured sealers
Discourages mold, mildew, and bacteria growth
Adding color to make old concrete look new
What happens if concrete is not sealed?
If concrete is not sealed, it quickly absorbs moisture, oils, and grease. Water freezing inside concrete causes more cracks, and oils can permanently stain concrete.
How long does concrete sealer last?
Acrylic sealers last 1 to 3 years on average. Epoxy or urethane sealers last 5 to 15 years. The total lifespan depends on the concrete-sealer type, quality, number of coats, and surface traffic.
When to seal concrete
The best time to seal concrete is in the spring or fall when the temperature remains 50° F to 80° F for 24 hours minimum. Old concrete must be completely dry before resealing.
Wait at least 30 days before sealing a new concrete driveway.
Wait 24 to 72 hours after staining before sealing.
Stamped concrete needs sealing every 2 to 3 years.
Liquid acrylic cure & seal coating is the only type that contractors can apply without waiting for new concrete to cure first.
How long after sealing concrete can you walk on it?
Most sealers take 12 to 48+ hours to dry before you can walk on it. The total drying time depends on the sealer type and local climate.
Getting estimates from concrete sealing contractors
Before hiring a concrete sealing contractor near you, be sure to:
Get at least 3 estimates to compare.
Check customer reviews on HomeGuide and Google.
Ask for before and after photos of previously finished projects.
Choose a licensed, bonded, and insured company with 5+ years of experience.
Get copies of the contract and detailed estimate before work starts.
Avoid selecting the lowest quote as quality may suffer.
Don’t make the final payment until after the work is complete.
