Ricardo was very efficient and handled my job nicely. Luis took out my old gas wall heater and vent, restructured the wall, put in insulation, drywall and stuccoed the area to make it blend with the room. The next day, the roofer came to put on the tiles. Nice job! Thanks, Therese

★★★★★MARGARET MERCADO7 months agovia Google

Ricardo came by at 5:30 on his way home. In two minutes checked my wiring FIXED. He was so nice and I am thankful for the repair. Thank you so much Ricardo.

I had a great initial experience with Ricardo when he came out to inspect my property and give an AC quote. Since then, it’s gone downhill. I was told I would get a quote 2 days after, and it’s now been 2.5 weeks. I called twice to ask about the quote, and it seems he forgot both times. No apology and he said he would get it to me asap (that evening/next morning). I still haven’t gotten a quote.
