Excellent service, as always!

Once again, Mike of Haas and Sons has provided top-notch expertise re: the wiring in our 1936 home in a historic district. Mike sorted out some old weirdness, made it safe and compliant, and upgraded our bathroom light and fan to a more powerful model. It wasn't the first -- and won't be the last -- time we reach out to them for help!
