We are taking him to court and was immediately served with a counter-suit. The mark of a true scoundrel. Open to class action suits, we know there are many others he has robbed. Contact me at; [redacted]

Description of Work
What a nightmare. Deserves 5 years in Federal prison for fraud. We hired Mike Ross from Houzz based on his shiny reviews. We were restoring a 1920's craftsman. Wanted to keep as much as possible while adding a bathroom and updating the wiring, plumbing, foundation, etc. Mike is quite the salesman, over-promised, under-delivered but charged a premium. Cost us a quarter million in the end. We discovered later he was using our money to pay off his legal fees and subcontractors from previous projects (unrelated to our own). Only took a couple weeks in to realize the HUGE mistake me had made by hiring Mike Ross from Addition Building & Design. First his project manager (Cameron, cost $20k), naively admitted to me it was her fist job ever. While rarely being on site, I spent most of my time training her on how to check work and basic construction routines. Mike Ross charged us double what the subcontractors were charging him, (I openly communicated with the subs since the PM was never there). When I scolded Mike for such irresponsibility he played the victim role. I've heard it many times and started preparing for the worst once Mike Ross showed his true colors. Hired sloppy subcontractors, underpaid them resulting in sloppy work, I've seen better craftsmanship in Rio's Favelas. The Electrician (unlicensed, cost $30k) failed to ground all of the new wiring or remove the old casing. A huge fire hazard. We didn't pass final inspection and have hired a competent electrician to correct all the mistakes. Another $5k wasted. The plumbers (barely spoke English) failed to follow our instructions when installing hardware & overflow valves and now our claw foot tub is close to useless, while the shower is an inadequate novelty at best. We have flooding under the water heater (from failing to install a pump) and inconsistent water pressure through-out the house. The painters slopped glaze all over the single pane windows on every side of the house, painted over peeling exterior paint. Refused to produce evidence proving he used the proper EPA approved lead sealing primer. The whole 1st floor was un-level (contract states to level floor). Kitchen floor tile (marble) is uneven with sloppy grout work. Another $15k for new tile and cabinets, (my designer is furious about replacing the custom marble counter tops. Hand picked from a unique slab). His license isn't in his name and is suspended for failing to pay workman's comp. The city is investigating him. There is so much more, the list goes on.

Having purchased our first house in Valley Glen, North Hollywood, we were aware it was in need of serious remodeling. A 1950s Ranch-style home, it came complete with peeling wallpaper, musty carpeting, and even some dilapidated walls. As first-time homeowners we were prepared to spend more money to improve it, but weary when we began meeting contractors. Buyer?s remorse already set in when we inte...
