I was getting increasingly anxious about getting the work done, so I decided to call Haines Electric. To my relief, Rich came over the same day I called. He was professional, explained everything that needed to be done, and provided pricing on the spot.
Rich was able to schedule the work immediately, accommodating my need to resolve the issue within the same week. He even considered the weather to ensure my appointment wouldn't be canceled. The team arrived on time and was meticulous in their work, finishing exactly as scheduled. Additionally, they identified a gutter pipe that could have caused problems and incurred extra charges later on.
Honestly, Haines Electric deserves 10 out of 10 stars! They exceeded every expectation. Thank you again, Rich, for your diligent work in installing the panel without disrupting the gutter. I truly appreciate it!
He was professional, knowledgeable, and super easy to talk to…he even explained what happened in a way we could actually understand. It’s clear he knows his stuff and genuinely cares about helping people.
Highly recommend Rich if you ever find yourself in a pinch (preferably not during a heatwave, but if it happens—he’s your guy!).
I had an extra outlet put in my bathroom. They were very neat and cleaned everything up when they finished.
I have used Haines Electric before and will definitely use him again.
