Thank you so much for your time and hard work.  Your crew was wonderful.  They were friendly, polite and did a great job.  Please tell them we enjoyed having them here.  Thank you again for a job well done, on time, and on budget.

Thank you so much for all your good work on our home remodel project this past winter.  Liz and I are very pleased, both with the outcome and even the process.   …I would like to mention three things that come to mind most readily as leading to success and that we most appreciate:  Your honesty, your polite and relaxed courtesy, and the quality of your finished work are all noteworthy and highly to be praised as ensuring our satisfaction.

I’m very thankful for the readiness with which you adapted to the project changes when it was clear our original plan would not work, and to the subsequent changes throughout.  Your advice and courtesy in working with me, and allowing me to work as well, is much appreciated, as is your tolerance of all my questions or complaints for which you never really made fun of me, no matter how ignorant (good move)!

You are wonderful to work with and that pretty much guaranteed that “Building our Dreams” was rather pleasant, rather than the nightmare so many experience.
