Hi everyone! Just joined the site with the help of the Internet . We started an in ground pool installation a few months ago, due to the landscaping we were delayed and then the weather got very cold, we are in the Northeast, Massachusetts- Cape Cod area. Anyway, the pool floor base - Vermiculite was installed a couple of months ago, they came to put the liner in but we had a few days of freezing temps so the Vermiculite crumbled apart. Today was 50 degrees and tomorrow looks good so they came out today and cleared out the old flooring and poured new Vermiculite. They put a tarp over the pool and put a heater under the tarp. They are planning on coming back again tomorrow (another 50 degree day) and install the liner. Is there anything I should worry about with this process in the winter? I assume I should see what kind of warranty I have for the installation because at this point we won't be using the pool for a few months, is it worth telling him not to bother until spring? Or am I overthinking the process? Any input on winter vinyl installations are appreciated! Thanks
