Un amigo me recomendó esta compañía y me pasó un cupón que le llegó por correo. Llame y able con Natalia fue muy amable me esplico que el descuento se aplica solo el primer mes. Me tomó mi orden y todo fue bien fácil. Los precios de esta compañía son los más bajos que encontré incluso sin el descuento siguen teniendo los mejores precios. Gracias

After 2 other companies fell through after months of planning, I called American Sanitation about a luxury restroom trailer the week before our event. Natalia helped me understand the differences amongst products, gave me a better deal, and peace of mind that we would get what we needed. Delivery was easy to facilitate and the driver, Effrain(sp?) was kind, clear, and helped us navigate some tricky bits about setup in our location. The trailer met all our needs. Thank you for helping ensure our event was a success!

We’re so glad we could come through for you on short notice! Natalia and Efrain will be happy to hear your kind words. It’s wonderful to know everything came together smoothly and the trailer worked perfectly for your event. Thank you for trusting American Sanitation to be a part of your special day!

Natalia saves the day for us all the time. They are quick and always on time. We never have to babysit services or call when we are skipped. If you rent Portable Toilets, you know what I mean. They are great. I would like them to expand to the East Coast and So Cal so they can cover all my territory. :)
Response from the owner · 3 months ago
Thank you so much for the wonderful review! We're thrilled to hear Natalia and our team continue to make your job easier. Reliable service is exactly what we strive for every day. And who knows—maybe one day we'll make it to the East Coast and Southern California! We truly appreciate your support. 😊

American sanitation has been serving our company for a couple of years now and they are great! Teresa goes above and beyond every time I call. She went out of her way to change the date and location of our service. We had a special event and needed it for the weekend. I highly recommend this company.

Thank you for your continued trust and support! We're so glad Teresa was able to help make your special event a success. We'll be sure to share your kind words with her. We truly appreciate your recommendation and look forward to serving you for many years to come!
