When I moved to TN back in 2009, we had the local internet provider come out and install the cable needed to be connected.
The technician arrived on time, introduced himself, explained what he intended to do, and began work. He started on the outside, running the line from the pole into the home.
He knocked on the door and entered to perform the remainder of the service from the inside. No booties on his shoes, asked to borrow my battery powered drill to drill a hole for the cable to enter the home, didn't connect the junction box with plugs, just screws into the sheetrock, then left the dust and debris from the work on the floor. Oh, and did I mention a greasy hand print on our wall.
While first impressions were good, it went downhill fast from there. Poor training? Inconsiderate of other peoples property? No pride in his work?
Little things mean the most when performing work in or on a residence. Think about any bad experiences you've had and what made them bad. Then think of great experiences you've had and what made them great.
Be and do the great things then reap the rewards of your extra efforts with great reviews, customer advocates and referrals.
