I've received multiple quotes from reputable concrete contractors for an exposed concrete driveway and sidewalk, and I've noticed one quote is significantly lower than the others. All the contractors seem to be offering the same scope of work. Can anyone shed light on what might cause this price discrepancy? Also, what should I be asking the contractor as a first-timer? Thanks in advance! Here's a brief overview of the job:
- **Scope**: Excavation, forming, pouring, finishing, cutting, and sealing.
- **Concrete specs**: 32 mpa with ACI stone and wire mesh, driveway thickness of 5.6 inches, sidewalk thickness of 4 inches.
- **Driveway area**: 21.6 feet by 42 feet for $16,000.
- **Sidewalk**: 56 feet by 4 feet, includes 1 or 2 steps with a curb retaining wall for $5,900.
- **Total estimate**: $21,900.
- **Warranty**: Covers spalling or cracking before winter but doesn't guarantee color matching. Frost heaving and salt damage won't be covered.
I'm in Ontario, Canada. Any tips would be greatly appreciated!

You might want to consider that some contractors may really need the work or simply underestimated the job. Double-check their references and past work, as lower quotes can sometimes hide potential issues down the line.
Given the specifications, it does seem like the Canadian quotes can be confusing with the mix of measurements. Just keep an eye on the quality of materials and methods being offered. The lower quote might be because they’re really pushing for work or possibly cutting some corners, so make sure they’re thorough in their plan!
You might want to check how deep each contractor plans to excavate for the driveway. If the base isn't up to par to handle the weight, and the low-balling contractor didn’t account for that, it could explain the price difference. Always good to dig deeper—literally!
Thanks for the input! The current driveway has old clay pavers from the 80s, and they’ve held up well. Does that mean the base should be fine?
