I've always had good results and good service by phone with the Viking staff. We used them in our old home, after one of our church members recommended Viking. The church had done well with Viking in the past , so it was suggested when the carpenter bee problem came up again to give them a call. We weren't disappointed! The service was done in less than an hour, I had a complete print-out of the work they had done when I returned from work yesterday, and members of the congregation who had a meeting there that day , while it was going on were completely informed on the procedures that were being done and had full confidence in what was being done! Viking is top-notch in our books!!
