“

I had Coronation Construction redo the ceiling in my garage, including drywall work and insulation, and I couldn’t be happier with the result. Sam was great to deal with from start to finish — clear communication, fair pricing, and very straightforward about the scope of the work. Everyone involved did a solid, professional job. The quality of the finished ceiling is excellent, everything came together exactly as discussed, and there were no surprises along the way. I’d definitely recommend Co
