Friendly, polite and knowledgeable technicians. I have dogs and they always shut and clip the gates just the way they found them. I always check but so far they have a perfect record. If I am home they always knock and ask if I have any questions or special problems they need to address. They leave a tag on my door and email a report so if I have any questions I can call. They are easy to get a hold of and I don't get a runaround. I have been using this service for three or four years.
