The site manager has contacted us to say he was very impresses with the team and how hard they worked. I appreciate it is very difficult because you have other commitments and have to rota your overtime but if you could send most, if not all of this team in the future, I know the client would be very grateful. 
Very pleased with the service, good lines of communication, excellent time keeper for the sampling appointment, results of the sampling provided quickly. Good Presentation of the technician and the corporate uniform.

I am writing to highlight the diligence and dedication demonstrated by your team while visiting our site. The residents and I noticed the enthusiasm and extra hours Darren and Andy put in to complete the work. I appreciated Darren's positive attitude and his ability to motivate residents to contribute to getting the whole site done in the time frame. He seemed to have a catalogue of spontaneous responses to different issues that he needed to address for residents. The residents were impresses with Andy's friendly and respectful behaviours while visiting their homes. His care and attention to detail was second to none. I was personally impressed with their professional manner and timely delivery of objectives. My colleagues also described the gentlemen as 'most helpful and very pleasant to work with'. I would be grateful if you would share our comments with your staff and express our thanks. 
Please can you pass on the customers' compliments to whoever was involved at the work this list weekend at the above site. The customer has called me to compliment the guys with respect to their attitude and the standard of work they carried out. As their efforts reflect well on us, please pass on my own thanks along with my customers.
