A Project Manager hired a contractor to remodel my condo. Turned out his license had been revoked for bad work, and he had been sued. I had to have my entire shower floor ripped out and re-plumbed and re-tiled. He ruined a floor tile job on a large sunroom that I can’t afford to have ripped out. Contractor is still working with a revoked license in Palm Springs.
Always check with the license board even if you trust the person. Get recommendations from people you know who have had work done that you can see. I got the project manager’s name from an online site, who supposedly vets their people. So much for that!
