Know what they say about our work

“After our new office had been fully renovated, a thick layer of construction dust covered everything, from ceiling to floor. Preservation Cleaning came to our rescue and was able to get rid of all the stubborn dust and grime that had coated every surface in our new space. The great thing was they worked around our schedule, did so in quick fashion, and on top of everything did an amazing job. I would strongly recommend Preservation Cleaning in a heartbeat. To sum up, I've come to the understanding that every business is different but realize how Preservation Cleaning delivers superior results ensuring client satisfaction by tailoring their commercial cleaning solutions to your unique company, making sure your business always looks its best. Thanks,

“On behalf of Marigolds and Onions, I would like to take this opportunity to thank you for the level of service and commitment to excellence you have demonstrated in all your dealings with our company. I find you to be very responsive and accommodating on, what sometimes, is very short notice. The quality of the work provided by yourself and your staff whether it is done at our production facility or off-site is exemplary. Furthermore, the work is always performed with a good disposition and friendly manner. We always look forward to working with Preservation Cleaning for the foreseeable future.”

“Preservation Cleaning (PC) did an incredible job cleaning our nearly 6 thousand square foot yoga studio before we opened in August. We took over an existing business and had a very tight timeline to get the space cleaned up. It was incredibly dirty, with dust from floor to ceiling, but PC was very thorough and did not stop until the place looked like new. They are reliable, well-priced, detailed oriented, and Ron is a very committed business owner. I highly recommend them and will continue to use them for our deep cleaning needs going forward.”
