When three quotes for the same driveway land hundreds of dollars apart, the difference is almost always in the scope, not the sealer. Here is an illustrated comparison, the levers behind a gap and five questions that expose it.

Same driveway, three quotes: an illustration
The table below is an illustration, not real quotes. It shows how three companies can price one driveway very differently while all using the word sealing.
| Line | Quote A | Quote B | Quote C |
|---|---|---|---|
| Price position | Lowest | Middle | Highest |
| Area | Guessed by phone | Measured on site | Measured on site, written on the quote |
| Cleaning | Quick sweep | Sweep and blow | Wash, then let dry |
| Cracks and oil | Not mentioned | Cracks filled, oil not treated | Cracks filled, oil primed, edges trimmed |
| Product | Called "premium" | Named type | Named product and data sheet |
| Coats | One, thinned | One | Two thin coats |
| Weather plan | Fixed date | Reschedule if wet | Reschedule, with reopening times in writing |
Nothing is wrong with a lower price if the job matches. In this illustration, it does not. Quote A is not the cheapest way to get the same driveway sealed. It is a smaller job.
Seven levers behind a price gap
- Preparation depth. A thorough wash and dry takes far more time than a sweep.
- Crack and oil work. Filling cracks and treating stains adds labour and materials.
- Product and dilution. A higher-solids sealer used at the label's rate costs more than a heavily thinned one.
- Coat count. A second coat adds product and time.
- Area. An estimated area can be too small or too large, and either way it skews the price.
- Business costs. Liability insurance, WSIB coverage, admin and reliable scheduling are real costs that some companies carry and others skip.
- Schedule flexibility. A firm that will wait for the right weather may quote differently from one that will squeeze the job in whatever the forecast.

Skip the guesswork, we quote your actual driveway, itemized line by line, free and no-obligation. Serving Kitchener, Waterloo, Cambridge & Guelph, with quotes ready within 1 business day.
Cheap is not always thin, and dear is not always thorough
A low quote can reflect a lean, efficient crew or an off-peak date. A high quote can include extras that your driveway does not need. Price by itself tells you very little, and scope tells you a great deal.
So the test is not which number is lowest. Ask what has to be true for the low number to be honest. Then check that against the paper: the measured area, the named product, the coats, the cracks and the weather plan. If a line is missing, get it added or get a different quote.

A request that brings back comparable quotes
Half the gap between quotes comes from each company answering a slightly different question. Send every one of them the same message. Something like this works, with your own details filled in:
I would like a written quote to seal an asphalt driveway in Waterloo. It is roughly 5 m by 12 m, has several cracks, an oil stain at the parking spot and a maple near the edge. Please list preparation, repairs and coating as separate lines, name the sealer, give the number of coats and say what you do if the weather turns. Please also send proof of liability insurance and your WSIB clearance.
Companies that reply with specifics are showing you how they work. A reply that ignores half your questions is telling you something too. Attach a couple of photos and you will get fewer surprises on the day.
Five questions that expose the gap
- How was the area measured, and what figure is on the quote?
- Which sealer, how many coats and how much product for my driveway?
- What preparation is included: cleaning, cracks, oil, edges?
- What happens if the weather turns on the day?
- Are you insured, and can I see the certificate and a WSIB clearance?
If a spoken answer does not match the written quote, trust the paper and ask for the quote to be corrected. If the answers are clear and the paper matches, you can compare on price with a straight face.
A starting point for your comparison
D&D Home Services publishes a starting price of $450 for driveway sealing on typical Kitchener-Waterloo homes. The final figure depends on the material, size and condition of your driveway, and quotes are free and confirmed in writing before work begins. The pricing page lists all published starting prices. Use that as one reference point, and set any quote beside it line by line.
Key Takeaways
- Quotes that differ by hundreds usually cover different jobs: different prep, crack work, product, coats and weather plans.
- A quote that guesses the area, names no product or lists no crack treatment is a smaller job, not a bargain.
- Business costs such as liability insurance and WSIB coverage are real, and they are part of why some quotes run higher.
- Ask five questions about area, product and coats, preparation, weather and insurance, and trust the paper over the phone call.
