Abell installed pigeon spikes on the ledges of our home. Due to the home being rented - the renters did not let us know that 3 windows did not open due to the spikes. A year later Abell came back to the house and trimmed the spikes so that the windows open again and all at no cost. This type of service to stand by their work is greatly appreciated. I would recommend Kris and Abell to anyone requiring pest control services.
