Our water heater was leaking and needed replacement.  Our plumber found leaves in the chimney and recommended Sid from Able Wood and Gas to check it out.  He came by later that day and told us our chimney liner was rotted and needed replacement.  He cleaned out the chimney and started up the water heater.  He came back 2 or 3 days later and installed a new liner with a bird proof cap on top. A+ service.  No wonder our plumber recommended him.
