We hired Ahearn to install additional outlets in our old house, which had unsafe electrical work in the kitchen and zero outlets in one bathroom. Chris and an apprentice converted old outlets to GFCI outlets in the kitchen and laundry room and created an entirely new outlet in the bathroom, the new new wiring for which involved Chris crawling around in wastewater from a plumbing leak we didn't know about (old houses are fun like that). Chris was a good sport about the plumbing issue and returned to finish the work after that was repaired and cleaned up.
I'd give more stars except for 2 things: 1) at some point when entering or leaving our yard on day 1, Chris and the apprentice broke our (admittedly crappy) gate and left a human-size gap in the planks. Had they told me at the time, I would have understood, because like I said, the gate is old and easily broken. But I only discovered it after they left, and having a missing plank was a security risk that I would have liked to know about sooner so I could fix it during the day. 2) After the job was finished, I found a thin metal rod sticking up out of the bathroom floor, flush with the wall...I imagine it's related to the outlet installation, but it was never explained to me during the process and I'll just have to hide it with a trash can or something.
Overall, communication was less than idea. I'm not sure we'll hire Ahearn again, but we do need our knob-and-tube wiring removed, and they do that, so...*shrug emoji*.
