I would like to thank you for your efforts with the procurement, design input and supply/delivery of the doorsets for Charlton Primary School. It was obvious from the outset that Principal Doorsets were offering a superior product to other suppliers. When offering the sample to the architect, I don’t think she even looked at the other samples as the quality on offer was clear to see.

Many thanks to the Lead Project Coordinator for his assistance ensuring we received the correct product, any discrepancies were identified at an early stage making our life on site worry free and a whole lot simpler. The installation went very smoothly and is testimony to your endeavours prior to manufacture.

Thank you Customer Service for your regular updates on manufacturing progress, delivery arrangements and notification of any issues. Even when we had a problem with one of the doors, you took the time to notify us of the issue and reassure all was being done to rectify the problem, this approach is very much appreciated on site. Principal Doorsets have been the one supplier I have not had to chase for information as the communication has been proactive and very helpful from the start.

Please pass on our thanks to the team who have manufactured the doors. The quality of workmanship is to a very high standard and we have received many comments on the quality of finish you have achieved. It is clear when people take pride in their work, and the results are evident in the finished product which are delivered to us on site – thank you!

I would not hesitate to recommend Principal Doorsets to our other sites, as the service provided has been exemplary. Thank you all for your hard work, skill and I look forward to working with you again in the not too distant future.
