Dear Mr. Pierce,
We are pleased to let you know that the latest work you and your crew did on our guttering project was finished to our complete delight and satisfaction. Your response to our original concerns in such a short and professional fashion compels us to give your company our strongest recommendation. Furthermore, the fact that you went far beyond what we could have ever expected of you give us reason to make you our first call should we ever be in need of similar or other roofing service.
Please find enclosed payment in full for the service rendered per your proposal dated May 1, 2013.
If any questions please feel free to contact us.
