How to Choose a Concrete Contractor in Metro Detroit

Ask how deep a base they compact and what material they use, whether they pour an air-entrained mix for freeze-thaw, what thickness and reinforcement they spec for your load, and how they space control joints. A pro answers in specifics — “we compact 4–6 inches of aggregate, pour air-entrained concrete, rebar in the driveway, joints every 8–10 feet.” Ask how they grade for drainage, too. Confident, detailed answers signal someone who understands why Michigan concrete fails and how to prevent it.

Be cautious of a contractor who glosses over base prep, does not mention air-entrainment, plans to pour thin to hit a low price, or shrugs at drainage and joint spacing. A suspiciously cheap bid usually means a thinner slab, less base, or no steel — savings that vanish the first time the slab heaves and needs replacing. Refusal to show proof of insurance or to put the spec in writing is another reason to keep looking.

Because concrete failures are buried, expensive, and slow to show, the contractor’s integrity is everything. We screen the concrete pros in our network for licensing, insurance, and a track record of pours that have stood up to Michigan winters — so the contractor quoting your driveway has already proven they do the base and mix right. You compare bids and choose; you just start from pros who build it to last, not the lowest number with the thinnest slab.
