I'm working on my back deck and I found some areas where the existing concrete needs repaired. I'll have to call a professional to have this done. At what point will they consider it too cold to do any more work for the year? I live in Ohio and right now the temperatures vary from 30-40 °F at night to 50-60 °F in the day.
40*f & rising is a good rule of thumb &, often, a spec on public works projects,,, if someone knows what they're doing, work can be done at 0*f if its properly prepp'd, placed, & protected while curing.
