Ideally, the wintertime is the best. As long as the temperature is at least 25 degrees and rising, concrete will be just fine. When temperatures are extremely cold or hot, additives can be added to compensate for the extremes.

Concrete does start to crack as it is poured and set. If the ground under it shifts or swells, then the concrete will crack. The vast majority of the time, you cannot see the crack. In rare instances, you may see a crack. Sudden changes in temperature such as extreme heat and no rain (a drought) can break down the bond between the cement and the stone added. If it is no wider than 1/8″ then a mortar caulk can be applied to keep moisture out. If the crack is wider than 1/4″ then you need to have a professional look at it.

It all depends on what you are pouring. If you are attaching a sidewalk to a patio, for instance, then you do need to have rebar drilled into the patio so that the concrete will set up better.

The salt that cities use on the streets and leaks of radiator fluid, oil, and transmission fluid can erode the concrete on your driveway.

Is the individual or company bonded? If some problems arise, your mortgage holder and / or insurance company may want some guarantee that the property is repaired correctly.

You should contact your insurance agent.
