Comparing paving quotes is harder than comparing prices on most other contracts. Two quotes can be hundreds or thousands of dollars apart and the cheaper one can still be the more expensive choice five years from now. The difference usually shows up in details that aren't obvious to someone who isn't in the business.
Here's what we'd look for if we were in your seat.
Base preparation should be specified, not glossed over
A real quote describes the base work in concrete terms. How much existing material is being removed. What's being replaced. What thickness of gravel base goes in. Whether the base is being compacted in lifts or in one pass.
Quotes that say only "prepare the base" or "site preparation" without numbers are leaving themselves room to do the cheapest possible version. The base is the foundation. If the line item is vague, push back and ask for specifics in writing.
Asphalt thickness and mix
The quote should specify the asphalt thickness in millimeters or inches, and ideally the mix type. Commercial parking lots typically need a thicker mat than residential driveways, and high-traffic areas inside the lot may need more again.
If the thickness isn't specified, the contractor can install whatever's cheapest. Two inches of asphalt over a poor base will fail much faster than three inches over a good base, but a quote that hides both numbers can look identical on paper.
Hot mix vs cold patch
All new paving should be hot mix asphalt. Cold patch is a winter-only stopgap repair material. It does not bond like hot mix and starts breaking down within months. A quote that uses cold patch on new installation work is a red flag.
Cold patch has legitimate uses for emergency winter pothole repairs when hot plants are closed. It is not a finished surface.
Drainage and grading
A flat-looking parking lot is rarely actually flat. Proper drainage requires specific slopes that direct water to drains or off-property drainage points. A quote that doesn't address grading on a new lot is incomplete.
If you have a lot with chronic ponding problems, grading is the entire conversation. Resurfacing without correcting the grade just produces a new surface with the same standing water in the same place.
Compaction equipment
Asphalt that isn't properly compacted while still hot will fail prematurely no matter how good the mix is. The quote doesn't always need to spell out the equipment, but a reputable contractor will be able to answer the question without hesitation. Ask what's being used: a single roller, a steel-wheel roller plus a rubber-tired roller, the sequence of passes.
Tie-ins and edges
Where the new asphalt meets existing surfaces (curbs, concrete pads, garage aprons, sidewalks, neighboring asphalt), the transition needs to be clean. A quote should mention how tie-ins are handled. Is the existing edge being saw-cut for a clean joint? Is the new mat being feathered or sealed at the edge? These details affect both appearance and longevity.
Concrete and line painting
Most paving projects also need curbs, sidewalks, line painting, or wheel stops. A complete quote either includes those items or notes that they're being handled alongside the asphalt work. If the project will need them and the quote doesn't address them, you'll end up coordinating multiple trades yourself.
Cleanup and restoration
Excavated material has to go somewhere. The quote should specify whether haul-away is included, and if any landscape restoration is needed at the edges, who handles it. Surprise charges for hauling debris off-site are common with low-ball quotes.
Warranty
Most reputable Calgary contractors offer a warranty on workmanship. Get the term in writing, the scope (does it cover settling? cracking? specific failure types?), and what triggers a callback. A vague "we stand behind our work" without a written warranty is worth less than the paper.
Red flags
Significantly lower than other quotes for the same scope. Reputable contractors don't undercut by 30 to 40 percent unless something's missing.
No specifics on base thickness, asphalt thickness, or compaction.
Pressure to sign quickly, or a discount that expires by end of week.
Door-knock leftover material from another job. Sometimes legitimate, often a way to dump material the contractor can't use elsewhere onto a residential property.
No physical address or no provincial business registration.
Bottom line
The cheapest quote is rarely the cheapest answer over the life of the surface. A complete, specific quote that costs more upfront usually saves money within five to ten years.
