AOS Drywall

AOS Drywall, run out of Chelsea by Alesandro Dossantos, is a drywall and plastering outfit whose name keeps surfacing for one specific kind of job: a damaged or unfinished ceiling. The company says it has been operating for 11 years. The reviews span a long stretch — ten of them from 2015 to 2024, most clustered between 2016 and 2021, with only two from the last few years. In a 2015 review, a homeowner described Alesandro drywalling a room after tearing down wallpaper and finding paneling underneath, calling the result better than they'd hoped for. In a 2020 review, a repeat construction-industry client called the team dependable after years of using various plasterers, and in a 2016 review a customer described AOS Drywall coming in to correct a job another contractor had started, protecting the space and finishing quietly. A pattern across several of these older accounts is cleanliness — floors and walls protected, materials left in place on request, the site cleaned before the crew left. More recently, a 2024 review describes Alex quoting a ceiling job the same day it was requested and completing it within a couple of weeks. Not everyone came away fully satisfied. A 2020 review calls the crew fast and friendly with a fair price, but says the reviewer wishes they'd stuck around to check the trash cleanup and finishing quality more closely before the crew left. On Angi and HomeAdvisor, AOS Drywall carries a 4.7-star average across 31 ratings; Thumbtack shows 4.8 across 30. Its Better Business Bureau profile lists an A+ grade, though the business isn't BBB-accredited. BuildZoom lists a Massachusetts Home Improvement Contractor license, #193513, as active for the company. Given how much of the written history predates 2021, it's worth asking about current crew size and recent projects when you call. For a ceiling or wall job, especially one that needs to be picked up after another contractor, this is a business with a long paper trail of finishing the work — just confirm the walkthrough covers cleanup before the crew leaves.
