I am not sure if I ever formally thanked you for the amazing job you did with our addition a few years ago and I would like to take this opportunity to do so now. Obviously the reason we called you to discuss our current planned renovation was because of the amazing job you did with our full house renovation. Guests in our house continue to comment on the quality of the workmanship. Friends and family see the final product but, what they don't see is the amount of work that was needed by your team to make our house magazine ready. You worked with us every step of the way, you understood all our concerns and you worked tirelessly to make sure things for us were as stress free as possible. I also need to mention that your entire staff (Dawna in particular) did a great job at sourcing material for us (not always an easy task given our specific requirements for the unique).
If you ever need a reference please feel free to pass my name along and I will be happy to speak with anyone considering your company. I will definitely let them know that hiring you will be a very good decision.
