Daizo - You visited me a number of months ago. I live in Japantown and I consulted you about bolting the foundation. (You said it was unnecessary.) I was wondering if you knew of any gas furnace specialists or perhaps heating systems specialists who I could consult with to get an estimate for replacing the furnace. (I would also need to have the asbestos removed, which I understand is a separate work item.) Thanks! -- Robert, . http://daiichienterprises-com2.webs.com/
