leak in chimney water comes threw brick
 
Hello
We have this problem with water coming threw the brick half way down chimney face brick on the outside portion of chimney on a finished sun porch and at inside ceiling.
We just had the chimney redone from the roof line up.The mason thought it was coming threw the flues, we have 3. 1 is for the furnace, 1 for the fireplace and 1 for the beehive stove on the sun porch. I caped off the 2 we are not using (Fireplace & Beehive ) but we still get it, so I have ruled out not coming down the pipes. I have just put on the DEFY heavy duty water sealer repellent to the entire chimney above roof to see if that fixes it. I have picture showing the problem areas, below the ceiling and in the attic. Any help would be a step in the right direction. I will need to find out how to post the pictures and will post link for the visuals this afternoon.
Thanks

When you say you had the chimney redone.was it a tear down and rebuild or just repointing the mortar joints?

Were new bricks used if it was a tear down?

Did the mason check the condition of the flashing?

How's the roofing in that area?

It could be that you need another coat of the water sealant,a flashing problem or roofing leak.

I'd start with checking the flashing and roof first,move on to a second coat of sealer.
After visual inspection,of the flashing:
You could use a garden hose ,held down close to the roof,isolating the chimney from being the problem and see if it leaks.
Then move the hose up the chimney till the leak reappears to find the trouble spot ending at the caps.
Give the water a while to seep into the interior as sometimes it will take some time before it appears.

Hello
Yes the Chimney was completely tore down to the roof line new bricks and flashing as well as new flues from the roof line up. All New in March, the roof was replaced 10 years ago so it is relatively new still. We had a problem before the new roof, they said it was the joints from the chimney and brick to get it replaced we just did. This link (if it works) shows the problem we are having. This is prior to the sealant I just put on the other day, so I don't know if it will fix the problem or not until the next rain. Now the Link http://share.shutterfly.com/action/w...2ZMnFw&notag=1

If it works you will see the problem if not I will try to post it on another site.

don't think the sealant'll,,,
 
solve your problem as its interior ( negative side ),,, ck your flashing ( step or counter ),,, from what i can see, the moisture appears to be coming thru the block, not running down either side of the block.

sorry i can't see your house from my house, tho.

That is a pretty horrible looking chiney cap.

A good cap should overhang the widest parts of the chimney by several inches and have a formed drip so the water drips down to the roof and not run down the chimney until it is absorbed or finds a leakage point.

The flasshing does not look good either and wonder if you have step flashing on the side of the chimney.

No chimney flashing is the problem.http://shim1.shutterfly.com/procgser...102AauGzJi2ZMh

Not to mention there is no flashing up that gable behind the chimney. You need a roofer, and you should also get rid of the caulking between the rafters and the chimney so they can breathe and dry out.

tinner is right,your metal flashing work is horrible,needs to be replaced,that`s where I would start,you may have other problems as well,you can also get steel? flue tubes to reline the 3 flues if there are further problems,---it looks like the cement cap has cracks at its edges where it finishes off to the brick

Hello

All this was done by a mason who has been "doing this for thirty year" I thought he would do it correctly. Now my problem is trying to get him back over. He did all the caulking inside and out when I first noticed that we had a problem. There is a ton of flashing on the sides and front, I will take a couple of pictures today if I can for your advice again. I guess at this point I should have a second Guy take a look and give me a price?

the roofing god 01-21-2008 11:58 AM

If you paid 1 guy to do it,have him come touch up the cement cap,but I would look for a qualified roofer to do the chimney flashing work,have the new flashing reglets(groove cut for flashing insertion,typically 1/2" into brick)above the other guys mess,cut the old metal flush to the chimney(if you try to pull it out it will weaken the chimney)replace the shingles at chimney perimeter,install strips of ice&water shield around chimney laying up the faces of the chim. 3",then put apron,step,backpan,and counterflashings

Hello
Thanks for the help,I took photos of the outside since this is where the problem is now suspected. He said that the flashing is set into the brick 1" and then overlapped 4" back also something about double flashed? I was surprised to see that all the flashing was on top of the roofing when it was done but trusted the work. Please see attached and let me know if it should just be re-shingled from the roof line down on the lower roof (sun porch) we have no problems of leaks or trouble on the house side (higher Roof) or the front of the house. At this point if I get anything done I would rather have it done right by someone else or at least get a different person looking at it. I am not even sure if I can get him back to do the cap the correct way. Here is the link to the new pictures, thanks
