Inquiry (采购产品): Wall sound insulation Do you insulate walls? My building has old plumbing and as a result I can hear when my upstairs neighbor showers or flushes the toilet. The water sound is extremely loud. Is this work you do and how much would you charge for a wall? thanks **** Hidden Message ***** Pelayo Leticia 92649 USA Company: None Phone: 949-777-7018 E-mail: lpelayo@telepacific.com **** Hidden Message ***** lpelayo@telepacific.com
