After setting a plan to deter squirrels and certain all had left the interior - John and Sebastian returned this week to seal the exterior of the property and entry hole made by squirrels. I am impressed by how well the fellows worked together, how quickly the job was completed and how tidy the property was left. Electrician is returning to wire the exterior light for what we all hope is the last time!! I highly recommend both John and Sebastian - explained the plan, took photos of the work, and pleasant to work with. Jane.
