Michael & Son Services' team of electricians, plumbers, and other home-improvement gurus have been keeping houses in tiptop shape for more than 30 years. Experienced, licensed, and bonded employees are dispatched to each job fully equipped to deal with any household malady, kitted out with a range of technical equipment, diagnostic tools, and handy spare parts. Electrical troubleshooting cuts down on interior lightning storms ($159), and technicians can repair and replace ceiling fans, light fixtures, and smoke and CO2 detectors to keep homes safe and comfortable (roughly $180 each). A full plumbing inspection ($150) ensures house tubes are free of clogs, loose connections, and extra worlds, and HVAC system cleaning and inspection prepares heaters and their labyrinthine ventilation systems for all the overtime hours they'll be clocking in the cold winter months ($69; $89 for a diagnostic to check for issues). In addition to electrical and plumbing diagnostic and repair, Michael & Sons provides a wide range of interior and exterior remodeling and construction services as well as general handyman work and moral-support hot lines for DIYers.
