We hired Acoustical Drywall Services for a seal and re-spray, and we're very happy we did. The crew was friendly, timely, and the job went smoothly. The new spray ceiling has all the qualities we like about acoustic (yes, we actually like our popcorn ceiling and didn't want to lose it), and is safer and easier to clean now. The choices for seal and spray contractors are very limited, in fact I think this company might be the only one in this area doing it, but thankfully they are the right one!
