How cold of weather can I lay bricks? I have a small job I need to get done
and I'm wondering if I can still get it done before winter really sets in.
Also if I can set the bricks in the day time, how long do they need to dry
before they may freeze over night?
Don't lay bricks (or pour concrete) if you expect sub-freezing weather
within a week. Ideally, you would want 30 day's of curing to maximize the
mortar's strength, but a 7-10 day cure will result in a high level of
Sub-freezing temperatures stop the curing process, and it won't ever
I had a similar need last year and used a product called "Winter Admix."
I believe that it was put up by Amstone. It worked well down into the
20's F. Using the old standby, calcium chloride will reduce ultimate
strength more than these additives.
I bought this at an Ace Hardware affiliated lumber yard.

It's done all the time in NYC too, but concrete is heavily "drugged".
Additionally, any deck pours or brick laying is weather protected (blankets
and tarps) and heated with temporary heat stoves or propane stoves.
