renter complaining about cleanliness

[Kundan Chand]

Hi 

I am 1st time landlord and chose to manage my home personally. We had signed a lease agreement with our renter which included deep cleaning of the home before they moved in. However the cleaner I hired did not do a good job and now the renter has sent me emails that they had to spend lot of hours to clean the home etc. and had to move around their work schedules to accomodate that. I am guessing they may be looking for some hefty compensation for house cleaning. How do I handle this?

Thanks
