Chimney Spalding

cameraman's picture

I have a brick chimney that spalding pretty bad , mostly towards the top and going approx. 3-4 ft down. I know the proper thing to do would be take it down to the good line and rebuild. It's to bad to replace just the bad bricks. I don't forsee in the next 2-3 year, maybe more, getting to it.

To buy me some time can I brush up and clear all loose material, caulk  cracks and put a feww good coats of paint to seal the brick to stop water penteration???

Just looking to buy some time.  It not very tall on a low pitched roof and would be ez accesiable.

The water is penetrating from the top.  You SHOULD NOT coat the sides with anything -- that will make the spalling worse.  You SHOULD attempt to caulk the top to close off any cracks where rain can get into the inside

What do you have for a wash on the top?   Often, it's either the deteriorated wash or an open gap between the clay liner and the wash.

By wash, do you mean the angled mortor that sheds water away from the liner??

 

From the view out my 2nd story window (chimney is on the 1st level) that looks intack. But have  not inspected up close.

 

Will get up there tommorrow and post some photographs.

Yes.

Look closely at where the flue liner exits out the top and the underside of the wash where it sits on the brick.

Don't try to coat with anything or try to use any brick sealing or paint  this will not help in stopping the water from penetrating. I agree with Danh caulking  the top will rather help you more.

Sorry guys, I have had time to climb out on the roof to photograph top of chimney. The view from the 2nd story window shows some crack along the wash, not bad but I see where I can repair.  I will follow up with photos, for thoses that has taken the time to respond, a big thank you!!
