Drywall Wizard started and finished the mudding and sanding in 1 day. Most people know that 3 coats are normally needed to finish drywall. Their work showed that 3 coats should be used. It also showed that their workers have not been trained to do drywall work, and have very little experience. There were literally hundreds of air holes, drag marks from dirt under the blade, unsanded areas, etc. Too much material was applied at the seams, so there is a high spot every 4 feet, where the seams are. On some outside corners, almost an inch thick of excessive mud was left on the walls. Once the drop ceiling frame was installed, it was easy to see how unflat the final result was. Inside corners have no straightness at all. After we complained about the poor workmanship, Drywall Wizard sent out the same crew, and they tried to cover up the poor work, which actually made matters worse. I finally gave up and fixed the walls myself, which took many, many hours. The Drywall Wizard crew assigned to our job only had one person that could speak English, so communicating was very difficult. They obviously had not received any training on how to finish drywalls, I guess they were getting on-the-job training at the expense of the customer. They didn't bring their own tools, and had to borrow our ladders, spotlights, etc. My recommendation, don't even bother getting an estimate from Drywall Wizard, and definately don't hire them. If you do anyway, at least do your homework, and learn about what you should ask for and what you should get. Also, do not sign their acceptance form when they claim to finish the job, even when they try to pressure you to do so. Take your time after they leave to inspect the work, with proper lighting, etc. It is easier to find the mistakes after the surface is primed. Only 4 photos can be attached in Angie's List. The 4 that I attached are typical of Drywall Wizard's workmanship, but I have hundreds more, and the room was only 30' x 20'.
