“I just wanted to write you and thank-you for the great job you did in painting the outside of our home. It was a pleasure to advise someone of exactly what I believed needed to be done, including painting, patching and caulking.
I then had to be away for a few days and when I came back the job was completed just as we agreed. Your pricing quote was reasonable and even though there was a little extra work, you did not charge me for the extras.
This was something I have never seen in any contractor. P.S. Just wanted to let you know you will definitely get any painting job contact we need in the future.”
