Sealing a whole lot or just the cracks

Zusashi Maintenance bills crack sealing by its own unit, $1 to $3 per linear foot, and it falls outside the per square foot sealcoat rate. For that reason, a lot can be freshly sealed and still failing at every crack. The two are bought separately, measured differently, and just one of them repairs anything.

Surface area is how sealcoating is measured. For commercial parking lot sealcoating in Mississauga and the GTA, Zusashi Maintenance quotes $0.20 to $0.40 per square foot for the two-coat application it describes. The entire lot receives the same treatment at the same rate, and the area is the number that sets the line.

The measurement for crack sealing follows the cracks themselves. The same Zusashi Maintenance page quotes $1 to $3 per linear foot for hot rubberized crack sealing, applied ahead of a sealcoat, and this site's sealcoating cost guide notes that contractors usually price and sell this work apart from the coating, in addition to the per-square-foot rate. That line item comes from the total length of cracking, which the lot's area gives no indication of.

The practical problem is that mismatch. If a property manager has a square footage and a per-square-foot rate, that person holds only the first part of a two-part job. Getting the second part requires someone to walk the lot with a measuring wheel, and no source in this site's price data publishes an average crack footage per square foot that would let anyone skip that step. Two lots that match in area, age, and traffic can still produce crack-seal line lengths that vary widely, so the only way to know which lot is being bought is to measure it before the quote is written.

Sealcoating works as a maintenance coating. The guide states that it slows oxidation and stops water, oil and salt from degrading the asphalt beneath, and that it will not repair structural problems, cracks or potholes by itself. Read together, those two statements describe a product that preserves sound asphalt and provides no benefit to asphalt that has already broken open.

A coating placed over an unsealed crack hides the crack from sight but leaves the opening unchanged. Water still travels through it into the granular base, and Ontario winter freezing still affects the water that enters. The lot looks resurfaced from the parking spaces and performs exactly as before, which is the particular failure mode this comparison is intended to prevent.

That sets the order. Zusashi Maintenance's own pricing says hot rubberized crack sealing goes in before a sealcoat application, not after it. A crack filled after the coating has cured leaves a fresh scar across new work, and it means paying for a second visit on a lot that already had a crew on it. Order of operations counts for more here than negotiating either rate.

Zusashi Maintenance's own worked example prices a 10,000 square foot commercial lot at $2,000 to $4,000 in total for the sealcoat under the two-coat application it describes. That amount covers the coating line alone. Crack sealing is added to it at Zusashi Maintenance's $1 to $3 per linear foot, and a lot with several hundred linear feet of cracking adds a cost that is not trivial next to the coating itself.

One cannot tell from the published data which end of Zusashi Maintenance's $1 to $3 band applies either. The repair guide is clear: this is one contractor's published rate, to be used as a sanity check on a bid rather than a market range; according to the same guide, two published sources covering the whole repair topic are enough to check a number and not enough to settle one. Once the footage on the bid has been verified against the footage on the lot, the comparison worth running is between a bid's crack-seal rate and that band.

The province's own HST page confirms that Ontario's HST rate is 13%. The ranges quoted here do not say whether HST is included or added separately, and that distinction matters more for a two-line scope than for a one-line scope because the same convention must apply to both.

The coating line, too, is less standard than it appears. The $0.20 to $0.40 per square foot band in the sealcoating guide is Zusashi Maintenance's published rate for Mississauga commercial lots, and it specifies a two-coat application. Action Paving, which trades as Asphalt Sealing, publishes a commercial price too but does not state a coat count anywhere on its pricing page. A one-coat quote and a two-coat quote at the same per-square-foot number are not the same purchase, and the guide's warning is that the cheaper-looking option is often the smaller job.

There is a second variable in the application method, and it has no effect on the price. Integrity Asphalt, which serves Toronto and Mississauga, notes that spraying covers large areas quickly and that squeegeeing pushes the sealer into the surface texture. None of the Toronto and GTA sources in the guide lists separate pricing for the two, so the method fits the scope conversation rather than the price comparison.

Compare those variables with the crack line, and one number in a bid can conceal three separate unknowns: the number of coats, the sealer application method, and how many linear feet of cracking the crew measured. If two bids each answer all three in writing, they can be compared. You cannot compare a bid that answers none of them to anything.

Cracks turn into larger problems. The asphalt repair cost guide lists what Zusashi Maintenance charges for the next two stages: general commercial patching at $2 to $5 per square foot, and pothole repair at $100 to $500 per pothole depending on size and depth. Compared with Zusashi Maintenance's $1 to $3 per linear foot for sealing a crack, those later prices are the whole argument for sealing a crack early, and the guide says so directly.

Patching brings a scale problem of its own. The repair guide points out that a lone small patch carries a worse price per square foot than the same area would as part of a larger job, since mobilizing the crew costs the same in either case, which makes isolated patches the most expensive form of the work. When patching would extend over a large share of the surface, the comparison shifts once more to the resurfacing guide, where The Paving Company lists $3 to $7 per square foot for an overlay on an existing surface, priced over the whole area rather than the damaged part. That amount is roughly ten to twenty times Zusashi Maintenance's $0.20 to $0.40 per square foot sealcoat range, the cost of allowing the sequence to run all the way through.

You combine the two lines because of mobilization. The sealcoating guide itself recommends asking for crack sealing and sealcoating in one bundled visit, since crack fill on its own runs $1 to $3 per linear foot in Zusashi Maintenance's pricing and doing both in a single trip avoids paying two separate site-visit charges. For smaller jobs the floor is explicit: Action Home Services, based in Toronto and Richmond Hill, lists a minimum sealcoating project charge of $300 for a small commercial lot of roughly 750 square feet, and that minimum does not drop for a smaller area.

The data provides no evidence of a discount for purchasing the two scopes together beyond the shared trip. No source in this site's price data publishes a bundled rate, a package price, or a volume reduction across the crack-seal and sealcoat lines. The only saving the evidence shows is one mobilization instead of two, and any bid that claims more is asserting something the published figures do not support.

The index contains 376 companies: 96 are listed under sealcoating, 87 under asphalt repair, and 47 carry both classifications. Those overlapping companies are the ones that can offer crack sealing and sealcoating on one contract. Forty of the 87 repair companies have no sealcoating listing at all, 27 companies are listed for sealcoating alone, and 7 for asphalt repair alone, so the single-visit option is real but reaches only part of the field.

The sealcoating listings are thinly distributed by location. Of the 96, Vaughan has 6; Burlington, Whitby, Brampton, Mississauga, Oakville, Agincourt and Islington-City Centre West each have 4; and 31 of the 96 have no area recorded at all. Category views are at sealcoating and asphalt repair, with area pages including Vaughan and Burlington.

The index contains 12,300 reviews altogether, spread across 352 rated companies. The median is 15 reviews per company and the maximum is 521. Twenty-four of the 376 companies have no rating. A median of 15 is too thin a base for judging any single listing, and the index does not record warranty terms, completion timelines, or licence status for any company, so a listing cannot answer how long a given crew's crack seal holds. You can check a listing against the bid instead: the coat count in writing, the crack footage measured on site, and both lines priced against their own published bands.
