Run away from this company. Our 6 week project is now a 6 month, never-ending saga of ineptitude and sloth. We started early in March - pavers and landscaping- simple job. Its now August and only the first task is complete. We picked BLack Diamond from several bids based on their purported project management capabilities (lies) and size/number of teams (more lies) to finish by the beginning of summer, our most important goal. Black Diamond failed at every opportunity. It was almost comical. Ordering materials in advance for the next phase? Nope. Team available? Nope. Their accounting department couldn't even keep track and bill us at milestones- we had to remind them. Once they finally started, months later, it was a single worker and that was it. No "team". Like one guy. Their operations department is a disaster. Their "schedulers" cannot produce a schedule for you. One "scheduler" chastised me on the phone because I "embarrassed him by calling customer service" to track him down after repeated lack of replies. He claimed we had no options but to use them, after a expletive-laden tirade - because I had asked for our project schedule (he didn't have anything). When we had finished with demo this "scheduler" was absolutely clueless- he had no grasp of the project, what was complete, what wasn't, what was next, etc. Presently we are on hold yet again while they dither, waiting on landscaping- our "scheduler" had two weeks to follow up with us but that didn't occur to him (to respond to repeated inquiries) and now he's on vacation. Apparently no one else can help. This company is a complete joke. They are rip off artists. Don't believe the sales pitch. All lies. The owner, should you escalate, is there to calm you down while, in the meantime nothing actually changes. We are filing complaints with the CA contractors license board. The designers, however, are quite good and responsive - ours is superb. Unfortunately, the designers are tethered to this dysfunctional back office clown operation that is incapable of delivering. Spend your money elsewhere. Take the design perhaps and use it, Don't expect Black Diamond to actually do it in any reasonable amount of time.
