I don't enter an Attic or Crawlspace without a $65.00 charge to the customer. If they don't want it, It goes on the outside of their Building. 1st Wallfish is included in that price, Any additional are $50.00 each.
Where I'm at, I have no problem with the customers paying. They don't want wires on the outside of their brand new $250,000.00 +++ homes.
I've been doing this for 15 years and will not change. With the price of an install, it's the only way to stay in business now.
