What separates a great concrete and masonry contractor from a cheap quote, and the questions worth asking before you sign.
Concrete cracks and heaves when the base under it is thin or poorly compacted. Ask about the depth of gravel base, compaction, and drainage before you compare prices.
Control joints and reinforcement manage where concrete cracks as it cures and moves with frost. A contractor who plans them is building for Ottawa's climate.
Concrete cures best in warm, above-freezing weather. Ask how the contractor protects a pour from early frost or extreme heat, both of which weaken it.
Sealing a driveway or walkway helps it resist salt and freeze-thaw damage. Ask whether sealing is included and how often it should be redone.
