We had a red squirrel that got into our house somehow! John Grady was the second removal company we had come, but should have been the first! He did a careful check around our whole house and then crawled under our back deck to look there too. It was under the deck that he found an access point and screened it in very well, screwing the screen to the house so it couldn't be moved. He also used a one way door he made so that if any squirrels were still in the house, they could get out. He came back 2 weeks later to remove the one way door and screened up that area, also putting expanding foam in to further seal the area. We have had no further wildlife activity in our house since John did this - including no mice, which we'd also had a few of every fall. John did an amazing job, at a good price and we highly recommend him!!
