Completed 1,500 sq ft basement. Roberto oversees the work of multiple crews - hangers/mudders. Quote did not include supplies, "stacking" drywall in the location, or disposal of remnants. Some suppliers will stack for a fee, or he can add it to your quote.
Nevertheless, quote was very reasonable, even with additional stacking fee. Okay, it was downright a steal compared to other all-in-one contractors. (GCs charge 2x for the same work). His crews are full-time drywallers - they were incredibly quick, efficient, and the final results are top notch. Only downside is that they're busy - so you have to be a bit flexible on timing (guys worked Saturdays).
You have to be cognizant that most of the workers I met speak minimal english. It wasn't an issue for me as it gave me an excuse to practice my Spanish, and Roberto would handle any discussions with the crews.
Final thought - look elsewhere if you don't want to get your hands a little dirty. I'm sure there's a AAA place willing to take your money.
