How long should driveway sealer last?
There is no single reliable lifespan for every Ontario driveway. The specific coating, existing surface, preparation, application conditions and use all matter. “Professional” and “DIY” are not product specifications. Check the product instructions and inspect the driveway before deciding it needs another coat.

Start with the actual sealer
Ask for the product name, technical data sheet and any written warranty. Compare the same material and application requirements when reviewing quotes. A broad promise such as “all professional sealers last seven years” does not tell you what is being applied to your driveway.
Manufacturer warranties also need to be read as written. For example, Henry advertises a four-year limited warranty for its 200 Driveway E-Z Stir product. That is a statement about a named product and its conditions, not proof of a universal resealing interval or a guarantee for a different contractor's work.
What affects performance?
Black Jack's application guidance identifies preparation, coverage and curing conditions as important to its products. It warns that excessive thickness, cool conditions, shade and humidity can slow curing. The directions for the sealer actually used should determine its application and return-to-traffic requirements.
- Existing condition: identify cracks, soft areas, old failing coating and standing water before deciding on the scope.
- Preparation: specify cleaning, treatment of contamination and any repairs instead of assuming they are all included.
- Application: record the product, date and agreed coverage so future maintenance starts with useful information.
- Aftercare: obtain the product-specific instructions before arranging vehicle parking or other work on the surface.
Do not choose a method solely because it is described as “commercial grade,” contains a claimed solids percentage or uses a particular applicator. Those descriptions need to be considered against the coating's actual instructions.
Inspect wear before scheduling another coat
Keep a dated photograph after the work, then compare the same areas during routine property checks. Note where turning vehicles, visible staining, loose coating or new cracks appear. Send those observations with a maintenance enquiry.
| What you see | What to discuss |
|---|---|
| Uneven fading or wear | Whether the coating needs maintenance and which areas are affected. |
| Flaking or peeling | The cause and preparation required before any compatible new coating. |
| Cracks, holes or soft pavement | Repair needs before considering surface sealing. |
| Water collecting in one area | The surface or drainage problem rather than assuming more sealer is the answer. |
Colour and water beading alone do not provide a complete assessment. Black Jack discusses a water test in the specific context of deciding when new asphalt is ready for its first sealing; that should not be turned into a universal test proving every old coating has failed.
When should you reseal?
Use the product's maintenance guidance and the driveway's observed condition. Keep first sealing of new pavement separate from recoating an existing finish: the installer and coating manufacturer may have specific weathering and compatibility requirements. Avoid promising the same interval for every surface in Kitchener, Waterloo, Cambridge and Guelph.
Once maintenance is appropriate, the application weather and curing window still need to suit the selected product. A calendar month alone cannot establish that the driveway is ready.
What to request from D&D
Our published driveway-sealing starting price is $450; the final quote depends on the agreed work. Send the address, surface photographs, approximate area and any known product or previous application date. Ask which preparation and repairs are included.

Driveway-sealer lifespan questions
Does professional sealing always last longer than DIY sealing?
No universal lifespan follows from who applies it. Compare the actual product, preparation, coverage, application conditions and aftercare.
Does a grey driveway automatically need sealing?
Colour alone is not a complete condition assessment. Review visible wear, damage, previous coating and the manufacturer's maintenance guidance before choosing the next treatment.
Can sealer repair potholes or structural damage?
A surface sealer is not a substitute for appropriate pavement repair. Identify holes, cracks, soft areas and drainage concerns before agreeing to a sealing scope.
