We appreciate the work you did on our stone flooring and to let you know that the floors look great! And, you should know that I found the project manager and staff to be very efficient, professional and genuinely warm and caring people. Thanks so much for getting this done quickly.

I just wanted to say a very sincere 'THANK YOU' for all that you did for us here at Wellington Centre. In my opinion you went above and beyond. You were so patient with me and all of the phone calls and questions. I do appreciate it and would be happy to have you put us on the list of references. I have had several people comment on how nice it looks and that the shine is fabulous. I hope to see you and work with you again some day. Thank you again.

I called Sigma for the work in our home after they had done a spectacular job cleaning, restoring and polishing the marble in the office where I work. The work took a little over three days, involved three workers, and the result was spectacular. The workers arrived promptly every day, always explain what they were going to do everyday, and were extremely professional. They fixed issues I had never even noticed. When it was finished I had never seen the countertops and floors so clean and polished. They did a great job, and I would hire them again for sure.
