I used Pigeon Busters several years ago when I opened my first cafe. I rented an older building in the west end of the city that pigeons had basically taken over. There was a serious pigeon problem and there was pigeon crap everywhere. Christian and his brother completely power washed the entire building - all the window ledges, soffits, fire escape, sidewalk, patio etc. That alone was a lot of work. Then they installed spikes all over the upper ledges of the building and along the roof edge. As this was an old building, a couple places where they installed spikes were on rotting pieces of wood so some of the spikes fell of. They came back several times to reattach the spikes and never charged me. They were friendly, professional and extremely reasonably priced in my opinion. I have also used them at my house for a small job where a bird had nested on my front patio.
