If you need a plumber in Massachusetts, look no further than Umholtz!
Mike was responsive to my messages and asked me to email him a photo of the broken water valve I needed to be replaced. Once I did that, he gave me an estimate and was at my house later that week.
Mike was polite and knew what he was doing when I showed him the broken valve that my washing machine was hooked up to. He replaced that and also went above and beyond - I had a new washer that wasn't installed yet, and he hooked that up, saving me the trouble and probably a lot of time too since I'm obviously not a plumber.
No doubt Mike & Umholtz will be the first place I turn when I have another issue.
