"We are always so pleased with your work (for 20 years now) and happy to refer you as we know the new clients will be pleased too. Thanks again,
"A short note to convey my gratitude with your company's great service. All is well with the sprinkler and so a green garden lies before us. Thank you again. "
"I wanted to let you know how impressed we have been with your services. We had some problems in the spring which you folks promptly looked after, and then in the fall you also provided great service which was appreciated. We will certainly recommend your company to anyone looking for similar services."
I wanted to thank you for the wonderful service today. I have had several companies come to my home to fix my system over the past few years and none of them got it working perfectly until today.
