Eric came by to assess my pigeon problem...after cleaning the roof (power washed) they put up spikes and screens to keep the pigeons out of the area they were nesting. A few weeks later they (the pigeons) relocated to another part of the roof...I called Eric who came out the next day...he serviced that area....at no additional cost. When he finished he said "let me know if you have any problems but that should take care of it." You can't beat that for service...
