I had to call them back after caging off the nesting areas didn't get rid of the pigeons. This time they put in spikes and no bird crap this morning so far and only one pigeon. We had assumed that caging would do the trick but it didn't only prevents them from nesting. Total cost was $470. They did a nice cleanup job too. I would use this company again. I had to knock their prices down though due to miscommunication we had some problems but Steve Vach will do his best to please you and make it right. The spikes come unglued and fell off the roof but they honored the warranty and fixed them.
