I have been in the construction clean up business for 15 years and have just encountered the strangest situation with paint and tape all over the interior of windows. Usually paint overspray and the tape is removed by the painters, but not this time. (they were thrown off the job) 27 windows were oversprayed with the primer (kilz) and the tape and overspray was left behind. What should be charged per window for the removal/scraping of the paint and tape?
