Certapro is AWESOME. Their customer service is spectacular and their commitment to customer satisfaction is amazing. I had picked out a Benjamin Moore colour for the complete first floor of my home and, unfortunately, the company they bought their paint from matched it incorrectly, and this wasn’t obvious until the whole floor was complete. Certapro stood by their service and did a COMPLETE repaint!! They also sent one of their top painters (Emil) to make sure the job was done to a very high quality. I was so appreciative of their above-and-beyond fix I hired them again 6 months later to paint my exterior.
One recommendation if you are particular (which I am): ask to have one of their full-Time painters do you work and not a subcontractor. Their permanent staff are AMAZING.
