I thought that my sump pump had ended its life and needed to be replaced. The contractor I found through Home Adviser came out the following day and arrived reasonably promptly. The technician tested the pump and it wasn't responding. He then checked the breaker panel and all seemed well. However he checked to see if power was reaching the outlet, it wasn't so he tripped some breakers and reset them and the power to my pump came on and the pump works so a replacement wasn't necessary. He charged $75.00 which I think was reasonable for a call-out fee and time spent.
The best source for this type of plumber is a general contractor. The contractor sees the plumber's work before it's covered up; you don't get that opportunity. In addition, your contractor knows the telltale signs of quality work that you might miss, like clean solder joints, crisp 90-degree angles at joints and clean, properly sized holes in joists, studs, and floors.
I had another lady who said she wanted to run to the grocery store to get some coffee to make for me and my guys while we were installing her new kitchen. She said she was just gonna run to the store and asked if we wouldn’t mind keeping an eye out for her one-year-old daughter who was sleeping at the time. We said fine, but she ended up not returning until four hours later. The kid was screaming her head off and we didn’t know what to do. We tried holding her. We didn’t know if she was hungry or what to feed her. She just kept crying.
