Mike Hornig
I contacted Tim on 5/11 after our previous window cleaner didn't show up (on the same day) for an appointment we had scheduled months ago. I told Tim we needed help ASAP because we were hosting a party on 5/20 (yesterday). Tim made it happen by getting us on the calendar for this past Saturday afternoon. Our windows now look fantastic and it was a pleasure working with Tim. I would be very comfortable recommending R12 to anyone in need of his services. Moving forward we plan on using R12 for our window cleaning and other services they offer.
Response from the owner:Thank you Mike for taking the time to write a review. I really appreciate it. Im also have been able to help meet your expectations and schedule
