A wash-and-seal package sounds like a bargain, because the wash is required anyway. Sometimes it is a smart way to book. Sometimes it hides a rushed wash or a thin coat. Here is how to tell the difference before you sign.

What a proper package should contain
Sealing only works as well as the surface under it, so a real package has more than two words on the invoice. Look for these lines, in this order:
- Cleaning and prep: how the surface will be washed, including stains, edges and joints.
- Repairs: cracks, loose units or sunken spots, and whether they are included or extra.
- Drying time: a stated wait between the wash and the coat.
- The sealer: the type, how many coats and how it is applied.
- Keep-off time: how long before foot and vehicle traffic.
- Cleanup and weather plan: what happens if rain arrives mid-job.
Sealing is also not one product. Asphalt sealers, concrete sealers and interlock sealers differ, and each has its own prep and weather needs. A package that says "sealing" without naming the surface and the product type is not telling you what you are buying.
If a package cannot answer those questions, the price has nothing to stand on.
When bundling helps
- One party is accountable. If the sealer peels because of a poor wash, there is no argument about whose step failed.
- Timing is coordinated. Washing, drying and sealing have to fit into a run of dry days. One crew planning both is less likely to leave a gap that lets rain or dew ruin the surface.
- Prep carries through. The people who cleaned the surface know how it behaved, where the stains were and which patches need extra care before sealing.
- Set-up happens once. Some of the fixed work, such as travel and unloading, is shared.

When bundling hurts
- The wash is presented as "free." A wash is a required step, not a gift. If it is free, the cost is sitting in the sealing line, and the wash may be a quick rinse.
- You may not need sealing at all. A sound, clean slab can go another season, and a wood deck needs stain, not the same product as a driveway.
- The line items are hidden. A single package total makes it impossible to compare with separate quotes.
- Weather forces a split. The wash day is not always the sealing day, and a package that insists on both in one visit may seal a damp surface.
Ontario weather adds a test of its own. Most sealers need a run of dry, mild days, and the product label sets the minimum temperature. A package booked into a cool, damp week, or into late autumn, is a red flag, not a bargain.
Sealed surfaces also need reapplying over time, so treat the package as the start of a maintenance plan, not a one-off.
The comparison test: ask for the pieces
- Ask for the wash priced on its own.
- Ask for the sealing priced on its own.
- Ask for the package price for both.
- Compare the package with the two separate figures, and ask what accounts for any difference.
- Check that the package includes the same prep, repairs and drying time as the separate versions do.
D&D Home Services publishes starting prices of $350 for pressure washing and $450 for driveway sealing on typical Kitchener-Waterloo homes, with the final quote confirmed in writing before work begins. Use them as reference points when you read anyone's package, and see the pricing page for the rest of the list.
Package, separate visits or separate contractors
Choose the package if the surface needs both, the itemized quote is clear, and one contractor will plan the dry-weather window. Choose wash only if the surface is sound and the coating still works. Choose separate contractors if each is much stronger at its own step and you are willing to coordinate the timing yourself.
How washing sets up a coating is covered in how pressure washing prepares surfaces for sealing, painting or staining. The two services are on the pressure washing and driveway sealing pages.
Key Takeaways
- A proper package lists cleaning and prep, repairs, drying time, the sealer type and coats, keep-off time and a weather plan.
- Bundling helps with accountability, coordinated timing, carried-over prep and shared set-up.
- Be wary of a "free" wash, a single unitemized total, or a package that insists on washing and sealing in one visit regardless of weather.
- Ask for the wash, the seal and the package priced separately, then compare what each includes.
