THE SHORT ANSWER
Estimate asphalt sealing from measured pavement area, preparation and defined crack work. Separate routine coating from pavement repair, and avoid promising that a sealer corrects structural defects.
This guide follows a fictional 1,200 sq. ft. residential driveway in Vancouver, British Columbia. The linked asphalt driveway sealing PDF example shows the scope and 6 separate costs in Canadian dollars. Treat it as a worked document, then use measurements, supplier quotes and labour inputs from your own project.
Sealing a driveway cost: cleaning, crack allowance and coating scope
An asphalt driveway sealing estimate should identify the existing surface condition and the area proposed for coating. Measure the usable driveway and record cracks or damaged patches separately. Sealing an existing suitable surface differs from resurfacing or repairing potholes. Ask the contractor to assess suitability before treating a coating allowance as a remedy for every visible defect in an ageing driveway.
Keep condition review, cleaning, agreed crack filling, selected coating materials, application and cleanup visible. Crack-treatment quantity may be measured in linear m, while coating quantity follows the product's stated coverage for the reviewed surface. Do not infer the required number of coats or product volume from a generic driveway area alone. Ask the contractor to identify their selected system and any supplier ordering allowance.
Compare quotations using the same measured area, limited repair schedule and proposed coating scope. Confirm the agreed access restriction and handoff arrangements without prescribing a universal reopening time. Oil marks, failed pavement and drainage issues can require separate treatment or repair. If resurfacing is recommended, request a distinct quotation so a higher-cost renewal scope is not compared directly with a cleaning-and-sealing total that excludes those works.
A separate worked planning example
Illustrative takeoff: 120 m² of asphalt and 24 linear m of agreed crack treatment. Calculate coating purchase from the selected supplier's specified coverage, with cracks priced separately; no universal coverage rate is assumed.
Cost and scope questions
Is sealing the same as resurfacing an asphalt driveway?
They are different scopes. A seal-coating quote should identify cleaning and limited preparation; resurfacing or pothole repair requires separate quantities and pricing.
Can I calculate coating volume from area alone?
You need the selected system's coverage and proposed application scope for the reviewed surface. Ask the supplier or contractor to state that basis.
1. Measure the coating footprint
Sketch the driveway, including branches and excluded surfaces. The 1,200-square-foot number is asphalt receiving coating, not lot or property area.
2. Assess visible condition
Record cracks, holes and failed areas. This example has a limited measured crack-fill line; potholes or resurfacing are distinct repairs.
3. State the selected system
Confirm product, preparation and application assumptions with the supplier and site conditions. The material dollar amount is fictional, not a coverage recommendation.
4. Explain access and curing arrangements
Agree vehicle access, adjacent-surface protection and handoff instructions for the selected product. Keep scheduling conditional on weather and product requirements.
Review the Canadian project address
For the 1,200 sq. ft. residential driveway in Vancouver, British Columbia, the example uses the measured trade units shown in its PDF. Residential jobs may mix square feet, linear feet, counts and supplier units; keep each line’s measurement basis visible. Check access, grades, drainage and seasonal site conditions. Confirm any property-line, utility, design or municipal requirements that apply before committing to the work. The figures are fictional CAD inputs, not a local price survey.
Describe which products the customer supplies and which the contractor supplies. State how any site condition outside the visible scope will be assessed and priced. Do not copy an allowance from another city or assume a sample’s tax entry establishes the treatment for this client.
Work through the asphalt driveway sealing quantities
The matching PDF lets the client check each extension of quantity and unit rate. For this example, two useful checks are:
- Driveway cleaning and preparation: 1200 sq. ft. × C$0.35 = C$420.00.
- Limited crack filling: 80 linear ft. × C$4.35 = C$348.00.
Adding all 6 lines gives a C$2,408.00 illustrative subtotal. The PDF records 0% tax and C$2,408.00 as its total, before any markup. These are chosen sample inputs, not prices observed in Vancouver, British Columbia. The measurement basis matters as much as the rate: a material purchase allowance may be larger than the installed area, while a fixture count is not interchangeable with hours of labour.
Check the scope before sending
- Measure pavement area.
- Count and locate cracks.
- Confirm product and condition suitability.
- Agree access and protection.
Outside the illustrated scope: No pothole repair, resurfacing, base repair, oil-remediation guarantee or coating of concrete surfaces.
Check the business and client names, property location, dates, quantities, unit rates and notes. Confirm tax, markup and any required approvals for the actual job. If selections or site conditions are unresolved, label the line as an allowance and explain how it will be updated.
Common questions
Will sealing repair a failed driveway?
No. Assess failed pavement separately and quote repair or replacement where needed.
Should crack filling be one allowance?
A measured length and stated repair limit make the allowance clearer than an undefined promise to fill all cracks.
