Sound Proofing Ceiling

kyastas0

Hello guys I have a customer who wants to sound proof his ceiling in the basemant. Because he is living in the house and rents the basemant. So his problem is the noise from basemant, he already kicked out one of his tenants because her's boyfriend used to play music louder. Now he wants me to do something that he woudnt be able to hear what is hapening in basemant and that tenants from basemant couldnt hear whats hapening in the house.

Also I have no idea how much to charge, because I do kichen ant bathroom remodeling most of the time and this kind of job got first time.

Thank you guys!
You are the best!
