Update for all...thank you for your input. And you were right!...we are in a cold snap and it was frozen pipes. Woke up to more frozen taps (over the garage) this morning.
Called a plumber, and by just turning the heat up in the house, turning on the taps a little, and adding a small heater in the garage, thankfully they are all working again. The kitchen tap just needed insulation put back around it.
I will have to blow in insulation in my garage ceiling and perhaps add heat tape on one of the pipes up there. Also, weatherstripping around both my garage doors. And maybe just put a small heater out there when the temp hits lower tens. That should do it.
Again, thanks.
