I've used Milton Frank Plumbing for a year and a half or so--maybe even closer to two years. I've mainly just used them for regular plumbing stuff like if the toilet is stopped up.
The last time they were here, though, they re-piped the whole house and installed a water softener. The job went fine. They are friendly. Their service people always do exactly what they say they are going to. They don't try and sell you something that you don't necessarily need.
