Hiring a driveway sealing company in the GTA

The answer depends on what the driveway is made of, because the products are different. Sika Canada's data sheet for Sikagard-690 Asphalt Sealer calls it a "bituminous emulsion", a liquid made with bitumen, the black binder in asphalt. The sheet says it "forms a uniform, durable black film" and lists protection against UV light, water, salts and oils.

Concrete sealers work another way. Sika's data sheet for SikaCem-102 First Seal calls it a "water-based silane-siloxane penetrating sealer". Penetrating means it soaks into the concrete instead of sitting on top, and the sheet lists it as "Non film forming". It describes a milky liquid that "dries clear" and "Does not enhance the color of the surface".

Two more jobs share the word. JHC Landscaping sells a "sand and seal" service for interlocking pavers, and Endura Stamped Concrete sells sealing and repair for stamped concrete. Ask any company first which of these surfaces it seals, and with which product.

The index has no sealing category, so the business name is its clearest signal. Of the 770 records, 19 carry "seal" in the name. Six of those sit in the floor-coatings category or carry Google's Waterproofing service label. That leaves 13 that look like outdoor sealing companies, which is a reading of their names, not a claim about their work.

Each record also carries a Google label, the business type Google Maps gives the company. That label is separate from the site's own categories. Across the 13, the labels are:

• Asphalt contractor: 7
• Concrete contractor: 4
• Paving contractor: 1
• Property maintenance: 1

The whole index holds 10 records with that label, and 7 of them are among the 13. Of the 13 sealing records, 10 sit in the site's Concrete Driveways category. A company filed under a concrete category may still seal only asphalt, so read the Google label on each profile.

All 13 sealing records carry a Google rating, from 4.4 to 5. Their median review count is 67. Over all 703 rated companies in the index, the median is 20 reviews. Two of the 8 largest review counts in the whole index belong to sealing names:

• No Limit Sealing Vaughan, labelled Property maintenance, rated 5 on 487 reviews
• the company named Asphalt Sealing, labelled Asphalt contractor, rated 4.9 on 324 reviews

No Limit Sealing also has a second record in Richmond Hill, labelled Asphalt contractor and rated 5 on 67 reviews. Both records list the same web address but carry different Google labels, a reason not to filter by label alone.

A large review count says nothing about the product that goes on your driveway. The site's methodology treats every company as if it started with 10 reviews at the average of 4.78, so a perfect score on a handful of reviews moves less than it looks.

Asphalt sealing is usually a flat price per driveway, while concrete sealing is usually quoted per square foot. Most prices below come from companies that sell the work, so each is that company's price for its own scope.

Action Home Services prints 2 figures for a 2-car driveway. Its price card shows $300 for about 600 square feet. Its question-and-answer section says $290 for the 2025 season, for about 600 to 650 square feet. On its own card, $200 for about 400 square feet works out to 50 cents per square foot. Set against Green Building Canada's $1 to $2 for concrete, that suggests concrete sealing costs more per square foot, though the sources price different scopes.

Cedarwood Development says crack filling, patching and power washing add to the cost. Ask every company whether its price includes HST (harmonized sales tax).

A flat price is only comparable once you know the work inside it. Action Home Services says its 2025 price for a 2-car driveway covers cleaning, painter's tape over the areas around it, filling "up to 30 linear feet of cracks" and the sealing itself. Its price cards also list 2 coats.

The Sikagard-690 sheet shows why the cleaning step matters. It says the surface must be clean, sound and completely dry. Oil and grease stains must be removed with a degreasing product. Major cracks and potholes must be repaired and then "allowed to cure before applying" the sealer.

The same sheet sells the product in a 17 litre pail and gives a yield of "Up to 40 m2 (420 ft2)". Read per pail, a 600 square foot driveway takes more than 1 pail for a single coat. Questions worth putting in writing:

1. How many linear feet of crack filling are included, and what does each extra foot cost?
2. Will oil stains be degreased first, and are potholes extra?
3. How many coats, and which product?
4. Is there a minimum charge for a small driveway?

Weather limits come from the product. The Sikagard-690 sheet says not to apply it when air and surface temperatures are below 10 °C or above 35 °C. It asks for "No rain for at least 12 hours after application" and recommends 24. It allows vehicle traffic after 24 to 48 hours.

The SikaCem-102 sheet for concrete asks for 7 °C to 32 °C during application and for 24 hours after. It says not to apply if rain is expected within 4 hours. Action Home Services, which uses an oil-based sealer, says "based on our experience" there is no difference in application above 0 °C. It says one can safely park after 24 hours.

These are different products, so the figures do not contradict each other, but they show why the product name matters. Ask the crew what happens if rain arrives on the booked day, and who pays for a second visit.

Ask what was used last time, because the SikaCem-102 sheet says not to apply that product "if the concrete has been previously sealed". It also says it "may not react on old concrete that is low in alkalinity", so ask whether the product suits an older driveway.

Instead of a fixed interval, that sheet gives a test. It says that when "water is readily being absorbed into the concrete, it is time to reapply". The 2 sheets checked for this guide give no fixed number of years. How often other sources say to seal is covered in the guide to road salt and concrete.

Decorative surfaces raise the price floor. Endura Stamped Concrete states "an $800 minimum for all jobs". Exposed aggregate has its own concerns, set out in the guide to exposed aggregate driveways.

The index holds no licence, insurance or warranty data it has checked for any of the 13 sealing records. The site's methodology says it does not verify a contractor's WSIB coverage, liability insurance or licences. What it stores are claims each company makes on its own website, read by the site's crawler and not checked.

Of the 13, 10 say on their own sites that they give free estimates. Only 2 make a licence or insurance statement there, and the site has not checked either one. When the site checked web addresses on 5 September 2026, 1 of the 13 returned an error.

No listing shows a phone number or an email address. Open the company's profile from the Concrete Driveways category, follow its link to the company's own website or Google record and ask your questions there, in writing.
