John Dirks Jr Posted March 9, 2009 Report Share Posted March 9, 2009 I'm pretty sure this chimney was added after the original construction. You can see the original gable vent that was pulled back. You can see the breach in the masonry work of the chimney. That is a metal vent pipe for a gas furnace that runs all the way out the top. I know this would be a big issue if it were serving a wood burning fireplace. What about in this case? How big of an issue is it? Also on the left of the photo you can see that there is gypsum drywall used on the gable ends. the paper is all peeled off and flaking away. I don't think I have seen gypsum on a gable in an attic before. I'm guessing this was the wrong choice of material for this location, no? Moisture of the attic environment has attacked the gypsum paper I guess. It'd that way on both ends of the attic.

Brandon Whitmore Posted March 9, 2009 Report Share Posted March 9, 2009 That opening in the brick is unusual. Did you see any structural concerns with that brick chimney (chase)? Since there is a B vent running through the brick flue, the original chimney is now just a chase. If there were no structural concerns, I would let the clients know that they can't use the brick as a chimney without repairs in the future, but as long as they keep the gas appliance, it it likely a non- issue.(depending on what else you see). I make not of the fact that the original brick fireplace (if that is what it was) is not accessible for inspection. I let them know that to convert back to a wood burning fireplace, repairs may be needed. (extensive in some cases). Quote Link to comment Share on other sites More sharing options...
hausdok Posted March 9, 2009 Report Share Posted March 9, 2009 Hi, If it's that drywall with the black paper backing it's most likely fine. There are exterior grade drywall products and I've seen a lot of little post WWII ranch houses here in the Seattle area with that black paper gypsum used at gable end walls where, after half a century, they're doing fine.

Tom Raymond Posted March 9, 2009 Report Share Posted March 9, 2009 I have to agree with Mike about the Gypsum sheathing, it's very common here too. I would add though that there is quite a bit of it missing at that gable vent, you can see the siding and J channel above the vent. That's a problem.

John Dirks Jr Posted March 9, 2009 Author Report Share Posted March 9, 2009 Thanks for the information. In the report, I'll talk about what's up there but I won't make too big a deal of it. Quote Link to comment Share on other sites More sharing options...
John Dirks Jr Posted March 11, 2009 Author Report Share Posted March 11, 2009 The cap was off of the leaning cleanout pipe. I took a whiff into it. It smelled clean. I would have expected it to smell like sewage. Does this tell anything? Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted March 11, 2009 Report Share Posted March 11, 2009 Rain drain cleanout by chance? I'd expect a sewer gas smell, just like you would smell on a vent pipe up on a roof. I wouldn't rely on my nose to tell me for sure, probably because I'm not in the habit of removing the clean out covers and sniffing them.

John Dirks Jr Posted March 11, 2009 Author Report Share Posted March 11, 2009 I didn't remove the cover. It was already off. I saw the pipe on the obvious angle and the depression in the ground. Don't know why I decided to sniff it. I found it odd that it did not smell of sewer. It's not a rain drain cleanout. I'm pretty sure of that.

Tom Raymond Posted March 11, 2009 Report Share Posted March 11, 2009 I'm not surprise by the lack of odor. Last week I had a loose toilet on one job and the whole house stunk. The next house had three open sewer lines inside and 8 square feet of effluent and paper waste in the front yard that had backed up out of the distribution vent (septic system done for) and I didn't smell a thing. I don't know why some of them don't stink, but I sure ain't complaining about 'em. Tom Quote Link to comment Share on other sites More sharing options...
