Old brick chimney with 6x6 clay liner. Water heater vents into it. Orphaned from furnace. Chimney needs new flashing including cutting reglet. It leaks and has been an issue in the past evident from water damage on framing members in attic. New direct vent water heater installed is about 1900.00. Knocking down the chimney and fixing decking and shingles is about 800.00. New electrical to water heater will be about 100. 3000 grand total. Leaving it be and reflashing will end up costing in the 300-1000 range. Its kind of screwy situation since a reglet cannot be cut into the mortar properly since there is a stone veneer siding on the brick. It is not as simple as installing standard step and counter flashing because of the veneer. Ive already spent close to 500 bucks on repair of the old flashing and I am still having leak issues. Do I hedge my bets, cut my losses and knock it down? Or do I throw more money into the old chimney?

I resealed by acid washed outdoor concrete patio last week. I took care to ensure that I didn't have any moisture prior to applying the sealer (Lumiseal Plus) but over the last few weeks, the sealant has bubbled and developed a white haze. I think I understand what caused it -- question is what can I do to correct? Any advice would be appreciated. Thanks
