As far as I can tell Geoff does a good job. He arrived at my house on time and cleaned my fireplace chimney and my furnace chimney. He charged $245 for the fireplace chimney and $120 for the furnace. He worked a little less than 2 hours. He was very professional. The price was too high for the amount of time on site. I think the same quality job could be done for far less. Two stars based on price.
