I have been buying stuff from Mervin Zimmerman, Inc. for years, but this was the first time that I had them come out and do work for me. They installed two toilets and a bathroom faucet. They were on time, and they did a good job. They were in and out, and the job went very smoothly! They made sure to clean up behind themselves, too. I am going to have them come back out and install a new kitchen faucet for me soon.
