I did note some moisture at other areas, but not of this magnitude...
Do you think it could be from the roof/chimney... the attic was not damp at the time of inspection, but has been in the past in that area... it appears to be coming outside the sheathing, behind the siding...
Appreciate any ideas/thoughts... I have written it up to the client to have a professional review/repair![/url]

I suppose it is possible… this is the gable end wall that it is occuring… and in the middle section of the wall… very strange… I could not come up with a solid point of origin…

What type of liner was in the chimney? Was the cap sound? How about the mortar joints above the roof line? I realize you probably couldn’t access the roof, but what did your binoculars show as far as the mortar joints. Was the attic venting adequate? That moisture through the block looks excessive. How old was the home and furnace. I see its LP. More details please.

Thanks for the replies guys… I appreciate it…
Adam, the furnace is vented through the chimney... it is the only source of heat as well. There is no return air line, the return side is open to the utility room, plus the filter...
The chimney definately has some issues and could very well be cause of the moisture on that wall... more than just a coincidence any way...

The chimney crown appears to be weak or missing. I find many third rate crowns that allow water in and distribute it in a confusing manner. Almost nobody around here builds a good crown.
I would have to get up close and personal with the top of that chimney before venturing a guess. Sorry about the snow.

It would certainly seem to be a chimney issue, whether the cap, (crown) or other. Depending on the furnace, the lack of a metal liner may be contributing as well. I would recommend further evaluation by a qualified chimney dude. (Not the guy that was there 3 yrs. ago)

Jeff - check around the roof ridge vent ( if the home has one) to see if water is entering around roof nails where the ridge vent is attached - or possibly improper step flashing/counter flashing around chimney penetration.

Definitely a flue issue from the furnace. With todays furnaces not having a pilot lot to keep a warm draft going up the flue, when the furnace goes off and cold air comes into the flue, it creates condensation. The older furnaces this wasn’t a problem but with the new efficient and spark ignition it creates problems. I would recommend and HVAC contractor install a metal liner. A further problem will be that the moisture will freeze and thaw causing cracking of the chimney.
