"I wanted to let you know that I've really appreciated the level of professionalism and personal care. I said from the very beginning that it was a lot of money so a big decision. And you agreed. I really appreciated how you were very clear with your explanations, how you addressed every concern and question and how nothing was too much trouble. Put simply, you took care and looked after the job. Therefore you looked after me and my home.
I know some would say that I'm paying for the service but this doesn't always ring true. I've dealt with a lot of people since owning a home and just because one pays, does not mean one receives what they pay for.
I don't often write a thank you like this but you deserve it.
Thank you for taking care and making sure my home is an igloo in summer and a sauna in winter.
I've been singing your praises to everyone I know and they're dubious. Until they come over and feel the chill! THANK YOU!"
