I just had the best bad experience once can have. I live in a semi-detached house and my neighbour and I share the attic. I've heard squirrels in the attic for a couple of weeks and spoke to my neighbour. The squirrels were entering the attic along the roof-line through my neighbour's side, this didn't concern her and she had no plans to fix the problem.
I know how much damage squirrels can cause and looked on Homestars and called Joe at Snap. What an amazing man! Not only did he fix the current problem but also patched the next obvious entry point. Plus took pictures of the job, explaining what he did. He also took pictures of damaged shingles that needing fixing on both mine an my neighbours house, saving us $$$$ way before we would have realized there was a problem!
What I really appreciate - he gave me an estimate for the job, realizing I was paying for my neighbour's house - that was more than fair, plus he did some additional preemptive work and didn't charge me extra.
Now that is someone I will recommend to my friends and family any day.
