Pipes freezing after remodel
I have a house which is balloon framed the pipes feeding second floor are in an outside wall .They have not froze for twenty years, they are insulated .After a remodel the outside walls were insulated, but I found out after, the contractor pushed the pipes against the outside wall when he insulated. I was not home when this was done or I would have made sure the copper type l coil with insulation would have been pulled forward and insulated behind. The last two winters they froze. any idea what can be done at this point ? Opening the wall at this time is not an option,cabinets,tile etc.
