You are getting taken. Get some more quotes and also look around your house for some self help. We realized a contractor whi put olin a box bay window did not connect it to the corner of the house properly and created the Appian Way for all neughborhood rodents. We had to pull up our deck and patch the hole ourselves but it did the trick for basement rats. We did have to hire a company to put screens over our attic vents which was less thsn 5k and seemed to solve the roof rats and flying squirrel problem. Good luck.
