Is $4,000 to install chimney liner and repair boiler venting a fair price?
Project Details
The homeowner was getting duct cleaning done when the technician claimed the boiler was leaking carbon monoxide and required a chimney liner. The homeowner also noted a sulfur-like gas smell and a leaking pressure relief valve on the water heater. A subsequent visit from the gas company confirmed a gas leak at the shut-off valve and meter, but no carbon monoxide was detected.
