I’m a landlord and exterior contractor. Everyone wants to cya, save money, and deny responsibility. However most of the time it’s simpler to just accommodate. If this has been a good tennant without a history of complaints here’s what I would say.
“Thanks for reaching out to me, some small damage and dust is to be expected when updating your home however this is concerning to me. I will contact the contractor about this, what can we do to make this right?”
Maybe they want a hundred bucks, maybe they want nothing and just need to express frustration, or want you to know they had issues in case other people were complaining as well. You don’t know what they want until you ask in this case. By asking what you can do to make it right is not an admission of guilt or accepting responsibility, it’s just asking what would make them happy. If they say they want $10,000 for their trouble then you have some questions to solve.
