Commercial stucco is not residential stucco at a bigger scale. The stakes are different: your building stays open, your schedule has penalties, and the finish gets judged by tenants, guests, and brand inspectors. Here is what to verify before you award the contract.
Check the license and insurance first
California requires a C-35 lathing and plastering classification for this work. Verify the license number on the CSLB site, then ask for current liability and workers' comp certificates naming you as additional insured. A contractor who hesitates on paperwork will hesitate on schedule too. Duarte's Plastering carries CA License #1097484, fully insured.
Ask about occupied-site experience
The hardest part of commercial work is not the plaster, it is doing the plaster while the property operates. Ask specifically: how do you stage around an open entrance? What does your containment look like? What hours can you work? We completed a full exterior program at an operating Marriott in San Diego where guests kept checking in through the whole project. That is the level of answer you want to hear.
Demand a real bid, fast
A serious commercial contractor bids from plans or a walk-through and returns numbers within days, not weeks, with scope, exclusions, phasing, and a schedule of values you can take to ownership. Vague bids become change orders.
Look at how they finish, not just how they start
Ask to see a completed project where sections were done at different times. Good commercial stucco reads as one continuous surface. Visible patchwork between phases means the crew cannot match its own work, and your building will wear that forever.
