Is $3,500 to perform furnace and water heater vent remediation a fair price?
Project Details
I recently purchased a home and was told during inspection that the water heater flue had insufficient clearance. My furnace is from 2010 and I just had the roof replaced less than a week ago. I am concerned about sinking money into venting for an old furnace or cutting into my new roof.
Quote Details
Significant vent work to address clearance and sizing issues for both the furnace and water heater. - Replace existing C-vent with B-vent - Increase individual venting systems from 3" to 4" - Increase combined exhaust system to 6" - Relocate exterior vent punch-through to address proximity to wooden beams - Cut new hole in roof for relocated vent
