Just a quick note to express my appreciation for the recent renovation work you carried out on my swimming pool.
I appreciate your very prompt responses to my initial call for assistance, your attention to detail and your communication with me during the life of the contract.
The work was completed before schedule and undertaken at the time it you said it would, which in my experience does not always occur with contactors.
I am extremely happy with the final result and the service provided by you and the persons you engaged under the contract.
Based on the work completed for me I would be happy to recommend you and your company to other potential customers.
