Our real estate agent recommended Warren when we were getting our house ready to sell it. Warren was round almost immediately on a Sunday afternoon to give us an estimate and talk us through paint choices. That estimate was exactly what we paid when the job was done. The next Tuesday and Wednesday, Warren and his crew (Adam and Paul) either repainted or touched up every wall in our 1500sq ft home. And trust me, with two young and energetic boys in the house, it needed a lot of touching up. The guys were very fast, left no mess and were cheerful and friendly throughout. (Warren is incredibly enthusiastic and cheerful. I suspect it's all the espresso he drinks.) The quality of the work was very high: no brush marks, missed spots or drips on the baseboards/floor.
I wouldn't hesitate to recommend Warren and we'll definitely be using him to redecorate our new house.
