GB Carrier Corp describes itself as an interior and exterior painting company for residential and commercial properties, and says it also supplies and installs drywall, from boom truck deliveries to finishing, repair and skim coating. The company says it has been in business for 40 years. On Google it averages 4.5 stars from 15 ratings. A recent customer credits GB Carrier and its team with making the restoration of an 1860 farmhouse possible, and says the owner is responsive and writes full scope estimates to avoid misunderstandings, with the work done on time. A recent customer says the company did both the carpentry and the Sheetrock on their job and even helped get the garage prepped; they showed up on time and left the place picked up. A recent customer who has worked with the Carrier team on several occasions, from their own home to projects they act as GC on, would recommend it for any drywall project.
What a great experience. They did a great job on both the carpentry and the Sheetrock. Even helped me get the garage prepped. They showed up timely, got the job done, and left the place picked up.

Great work all around. I’ve worked with the Carrier team on several occasions, from my own home to projects that I am the GC on, big and small. Everyone is great to work with, from the field team to the office staff. I wouldn't hesitate to recommend for any drywall project.
