The cost to seal a driveway in Washington ranges from $260 to $1,290, with most homeowners paying around $640. Your actual cost depends on several factors specific to your home and the Washington-Arlington market.
Sealing is priced per square foot — a standard two-car driveway (400–600 sq ft) is the primary cost factor.
Cracks, potholes, and oil stains must be repaired before sealing. Significant crack filling or patching can add $200–$500 to the job.
Coal tar sealant is cheapest but faces environmental restrictions. Asphalt emulsion is most common. Acrylic sealants cost more but last longer and are eco-friendlier.
Two coats of sealant provide the best protection and longevity, typically adding 30–50% to the material cost versus a single coat.
Individual cracks should be filled with hot rubber crack filler ($1–$3 per linear foot) before sealing for the best results and longest seal life.
The Northeast tends to have higher labor costs, partly driven by stronger union presence and higher cost of living. Stricter building codes mean more inspection requirements — budget extra for permits.
Driveway sealing in Washington generally does not require a permit for standard installations. Check with your local building department if your project involves panel work or structural changes.
Year-round construction seasons give you the most flexibility for exterior projects. Take advantage by scheduling during slower months for potentially better rates.

Asphalt driveways should be sealed every 2–3 years for optimal protection. Concrete driveways need sealing every 3–5 years. The best indicator is when the sealant has visibly worn away and water no longer beads on the surface.
Yes — driveway sealing is a feasible DIY project. A 5-gallon bucket of sealant ($20–$40) covers about 400 sq ft. Clean the driveway thoroughly, fill any cracks, apply sealant with a squeegee applicator, and allow 24–48 hours to cure. Two thin coats are better than one thick coat.
