Evelyn, I would like to express to you what a pleasure it is working with Preston.

Before Preston walked into my office and explained he was our account rep. I was looking and taking bids from other janitorial services. I decided to wait a little longer and give him a try before pursuing other avenues.

His diligence and persistence to your cleaning standards are to be commended. He has excellent follow-up skills. At this point he is the reason I am no longer seeking another janitorial service.

I know that people are always quick to complain and slow to praise. I just wanted you to know my thoughts on this matter.

“ I am pleased to offer this letter of recommendation to Courtesy Building Services lnc also known as CBSI and Gary Smith. Gary and CBSI have been my Janitorial Service company since 2004 and are extremely dedicated, reliable, proficient and most importantly honest. Gary has taken pride in his work as well as representing CBSI. Gary is always going above and beyond to make sure we are taken care of and that we are completely satisfied. In all the years we have been doing business together, I have never had an issue that Gary has not corrected immediately. Gary exemplifies the words of quality and customer satisfaction. Gary is someone you can trust. Besides the Janitorial Service cleaning contract l can also rely on Gary for those extra handy man jobs that need to be performed around the office. Gary and his crew will change light bulbs, as well as, perform minor building repairs and maintenance. It is very convenient to make one phone call and know it will be taken care of and done right. I highly recommend Gary Smith and CBSI for all of your Janitorial Service and building maintenance requirements."
