From my initial contact with Sentrex, i have been impressed with not only their customer service but also their understanding of our business needs. I did not expect, nor did i receive from other cleaning companies such an in depth consultation. Sentrex have obviously done their homework when it comes to how they present themselves to the customer. Due to the very professional approach, I expected Sentrex to outbid themselves, but again, they surprised me when they turned out to be one of the lower quotes i received. I moved forward with our contract, dubious that the high standard shown throughout the bidding process and by the management team would not be represented in the end product. I was very wrong. Sentrex have been excellent at all levels of the organisation. Very pleased. Long may it continue.
