The caulking could be a problem. The caulk should be allowed to dry

I am in the same boat. The caulk is a BIG issue. It stands between
you and leakage for 30 years; you do not want it compromised. I am
insisting that they only do the install when the air is 50 or
above.

Alternatively, ask to see the caulk tube and read the temperature
range in which it is to be installed.

Any other materials that would work just as well and perform better in
freezing temperatures?
