Going out on a limb here, but since you said this occurred in a few places, it sounds like more than one fix. Assuming you are using a residential plumber, not commercial (which is more expensive), and assuming not an extremely high cost of living area, I would start by suggesting one full-day for a minimium two-person crew. In my area, last time I checked, that could run as high as $1,400. Plus $250 for parts, a little profit and truck fee, etc., and you could be in for as much as $1,750.
There are mom and pop plumbers out there who work for a lot less, esp. in certain parts of the country.
Keep an eye out for mold that might start due to water saturating hidden surfaces, which could get very costly to remove later on.
Edit: this is for the plumbing only. If repair to walls/floors/ceilings is required to access pipes, there may be additional costs to restore those areas requiring accessing them to replace the pipes.

never completely shut off all the water. Running water doesn't freeze. Now you know!
Never pour grease down the drain either
don't buy those "wipes" that supposedly substitute for toilet paper
additionally, if you have one area of pipe particularly prone to freezing, you can heat wrap it with heat tape, which greatly reduces the chance those pipes will freeze.
The shameful thing is that no one is suggesting that you learn yourself and fix it yourself. Plumbing is not hard, it's thousands of years old. Yea for real. In this age of limitless information, why is your choice to "not know?" What if it happens next year? What about figuring out what the root cause is and how to fix that as well?
