I hired a plumber to put in a boiler and foolishly paid him in full before job was finished. All he needs to do is install a hard wired CO detector and remove my old boiler (in my back yard). Also there is a very slow leak in one of water pipes into the boiler he needs to fix.

This plumber has disappeared off the face of the earth. He was supposed to have pulled a permit for the job although I never actually saw it.

My questions are:

I live in Massachusetts. What office do I call to find out if he actually did pull permit.

What should I do to handle this other than call Better Business Bureau.

Thanks in advance.

Not all permits are required as sometimes repairs do not require one.
As for the other bad repairs he did, do you have small claims court in your area?
