Gates is significantly more expensive than some wildlife removal companies, but they are one of very few that seem to be insured. I get very nervous when I see someone the age of my sons going up on our high roof. With Gates, there is at least some peace of mind in that their workers are covered.
A few years ago, we called Gates when our neighbour thought squirrels were entering on our roof. The workers determined that they weren't entering and didn't charge us anything.
Recently, after we actually saw the bushy tail disappear under the soffit, Dan from Gates installed a one-way door and screening for the base price. He meshed up another vulnerable area for an extra charge (as expected). When he returned to seal up the original entry, we asked him to check a hidden, vulnerable junction that we had just spotted from our balcony on the other side of the house. He checked that and meshed it off with no extra charge. His service was prompt, friendly and professional. When there was a delay, he called. I hope the problem is resolved. Time will tell. But, if there is any further problem, my hunch is that the company would be helpful and forthcoming.
