We are so impressed

I just wanted to send a note to let you know how impressed and happy we are with the work that they did this weekend. We found places that they cleaned that have not been cleaned since we opened a year ago. We are so impressed especially with the floor in the warehouse office and just amazed at how clean it is. Thank you all so much for coming thru for us. We will have items moved on Friday to prepare for the floor strip and wax as well as the carpet.

Keep up the good work.

The office looked fantastic on Wednesday when we came in. Everyone in the office commented on how good the carpets and floors looked and how clean the kitchen was. We also noted that our phones were cleaned and our desks were clear of dust build-up. These are always areas of greatest concern to us. We appreciate your consideration and hard work and would recommend your services to anyone. We are sincerely grateful for your efforts.

Keep up the good work.
