Recommended Customer Reviews

We found Joel on the internet. We did not read the YELP reviews but we are not surprised by the 5 star reviews. Joel and his son came out to our house within 30 minutes! He spent a lot of time with my husband installing a very comprehensive commercial heater for our workshop. We bought it on craigslist and it needed some altering as well as it had a broken thermostat. Joel explained to my husband how and where it needed to be installed and the kwh, amperage, etc. I was not an easy install as the heater was complicated and missing some parts. Joel came back on 2 occasions to make sure the new thermostat was properly installed and everything was safe and ready to go. Very reasonable priced. Joel is reliable and has lots of electrical knowledge

Joel is a humble, reliable, proficient electrician. He come over for a quote on a Sunday and started work on Monday. He ran a main electrical line across our house, through two floor levels, back down to our master bathroom for floor heating. He did this with very minimal drywall cutouts. Then he ran electrical lines for 4 fans in our upstairs rooms. He worked without taking any breaks. Joel is a humble and honest guy who quoted the best price out of three separate electricians. His work is so solid I asked him to come back this weekend to install a 6' drop down fan in our living room. I've recommended him to other friends already and recommend him to everyone else. This coming from a guy who has used the heck out of yelp, but only ever written one other review. He earned it!
Oh, and he accepts credit cards.
