We had work done about 3 weeks ago after having gone from zero pigeons to a large loud crew since we had solar put on our roof (if you do solar, have bird fencing installed with it or very shortly after!)
The Pigeon work that 'The Pigeon Guy' did immediately moved the majority of the birds off our roof with a few hanging out trying to get back to the great shade they had. Now, after a couple more weeks, they have moved on completely. This is exactly what the folks told us would happen.
My only complaint was that they showed up one day early without notice. They had rescheduled us and not told us. However my wife was home and it was no problem. (And this is why this is a 4 not a 5)
She said they were very professional (as was the sales guy who gave us the quote).
good people, good work, and a good price. We have no complaints except that I wish I had found them 6 months ago.
