I've got 2 good customers who are having construction work done at their homes. One is adding a larger enclosed deck, but the other is under going a major renovation. They took the roof off and are adding another floor and along with this, the rest of the house is being gutted also. Went there last week and I can't mow the lawn as the entire front yard(approx. 2k sq. ft) had trucks, dumpster, lumber, machines, etc parked on it. I'm sure when the place is finished that there's got to be more than a few nails left behind. I can get that tire seal stuff(Slime), but I was just wondering any of you ever were in the same situation and got a flat or 2 from leftover construction debris and charged for the inconvenience of getting a flat. Thanks
