4.9★★★★★★★★★★· 303 reviews
“Thank you Sergio for coming on such short notice and making yourself available! Sergio was able to fix a door hanging incorrectly, plumbing, bath spout, electrical and wall-mounted a TV in minutes! Very knowledgeable and professional. Thanks again!”
“Sergio went beyond the call to fix a hole in the wall. He found the cause, fixed the hole, but also replaced the gutter, sealed all the cracks in the area and repainted everything to match. He also did some highly skilled drywall work (the ceiling has curved corners). I'm impressed and would definitely use him again.”
“Sergio was really good and honest. He knew exactly what he was doing when replacing my garbage disposal and fixing one of my kitchen cabinets. I would recommend him to other people who need a good handyman.”
