Hello all. I wasn't sure what forum to post this in or if it is even ok to ask questions here. I live in Ohio in a home built in 1913. I have had horrible problems with what I think is condensation right at the ceiling/wall line on the second story at my chimney line. Only happens in the summer and only in high humidity. I have typed out everything I have tried. I am at a loss !
Nothing appears to be leaking in the attic even upon heavy rain. Condensation/water only around wall/ceiling at chimney wear it meets second story ceiling from attic to second story ceiling/ wall.
2012 – New HVAC with AC installed late in season. AC rarely used if at all. No condensation or water on ceiling/wall.
2013 – Summer season started to notice wall getting some condensation/wetness. Nothing done. Fall through spring no problem. Wall/ceiling dry.
2014- Summer season noticed wall getting some condensation/wetness again. Attic checked no apparent leak coming through roof, even upon heavy rain. Had chimney above roof line sealed on outside and around roof line. This was late in the season and the wall started to dry. Fall through spring no problem. Wall/ceiling dry.
2015 – Summer season started to notice wall getting wet again and now into ceiling. July 2015 took chimney off to below roof line. Put up B vent and liner in chimney. Water heater and furnace routed through that liner and B vent. End of season wall/ceiling dried out. Fall through spring no problem. Wall/ceiling dry.
2016-2019 – Every summer season wall/ceiling would get wet and then dry totally in the winter through spring. Looked for leaks in attic/roof. Nothing else done.
2019 – Summer season very wet wall/ceiling did the below
Put in roof vents, 2 gable vents, wrapped chimney in attic with insulation, changed any old pipes in basement, mortared in spot that was open in basement to chimney and in kitchen where old stove pipe was from many years ago. Knocked out a part of wall where it was really wet in wall. Totally dry under it and chimney brick dry. Looked in attic again no active leak. Condensation/wetness in wall ceiling seem to be worse. At the very least no change.
