Dear Mark,
This is to thank you and all the staff and contractors of Pacific Remedial for the work done on the roof. This started as what we thought was a simple exercise in laying the new roof membrane but of course the job was magnified tremendously as the result of your discovery of concrete "cancer", faulty parapet, loose bricks etc etc.
I would like you to know Mark, the work that has been done is excellent and i must say the service we have received has been of the highest quality.
I would be very pleased to act as a reference on any future building projects that you contract or quote on.
Once again, thank you for a job very well done.
