We are probably working at the time and there is noise around. This video shows the real sound of a grinder running. Stump grinding is very loud and we don’t hear the phone ringing. We worked at this site for about 6 hours. And all this time we couldn’t answer the phone. How can we get in touch with you then? Please text us for free estimate. We take short technical breaks about once an hour and during this time we check our emails and respond to messages. See you soon.
