REPAIRING A CONCRETE CHIMNEY

Repaired a concrete chimney cap this morning. I recoated the top of the chimney using hydraulic cement.

This just made my day! Thank you for sharing!!

[@garycook9622]

Chad, Is this really the technique you have would used?

[@user-pr9lq8on5q]

Looks good. Very helpful. Was gonna seal cracks, now I know the right way. Thanks

[@397coney7]

Can you still use that type of cement if the old cap is broken and more loose then the one you worked on here? Hard question to answer without seeing it I know……

[@superroofer3130]

As long as all the loose stuff is removed and it's not big chunks missing. If you have large pieces missing I recommend type S concrete.

Just remove the crown and lay a new crown with wire mesh inside. It's such a small crown. What you just did is going to Crack in a year. Too thin. There is a reason crowns are thick. Do it and Do it right

[@SS-vw3rp]

What do you charge for a job like that

[@aftech7268]

Those are old methods That will guarantee to crack in a few years i see it all over the neighborhood … use ploy-seal … with a mesh and it seal will last 4x longer than concrete can withstand expansion and contraction

I appreciate your hard work, but I would not recommend this repair. You need to have a bonding agent between old and new masonry products. Addotionally, this repair is likely to crack in the areas soon. It would be better to remove and replace.

Here's a video of my crew roofing the same house a couple years later and I specifically show the chimney cap and that it hasn't cracked or came off. kzbin.info/www/bejne/laGunZ5prpuXZpI

@@jepp0711he didn’t correct you. Two years later means nothing.

​@@jfdb59I got a quote for $4k to rebuild my chimney, but a bag of mortar and a few tools was under $100. If this buys me several years, it's worth it to just do it again then.

[@ddawg6482]

​@@jfdb59it's expensive to replace the entire cement crown. Even a new one could theoretically crack in a few years so this seems like a reasonable cost effective approach

Thats gotta be bad for the hands

[@petecolorado5387]

Protect your hands and wear gloves cause you're going to end up with skin problems. Thanks for sharing.

How NOT to flauncher a Chimney !!

[@josephpetrillo2243]

This is not how to fix you chimney. A properly framed and poured chimney crown is what to do.

[@vicschauberger2737]

Yes . Among other things you remove the entire cap and replace it all. It's such a small cap to begin with . Do not do it this way .

[@vicschauberger2737]

Sorry . Nothing personal , but this vid . is moronic .

[@qsurface3799]

So much wrong with this!! Crown should have two inch overhang and there should be a cushion between the flue tile and crown. Not pre wetting the existing crown for the new concrete to adhere to plus wrong type of concrete to use! This is why you hire a professional chimney sweep to do these repairs. It’s a speciality trace. That repair might last 6 months and be cracked again.

[@michaelrojas5738]

Yikes…. For those watching, do not use this video as an example. Chimney crowns that are cracked need to be removed and replaced with new cement along with a bonding agent to the masonry…

[@tracyblack1509]

That stuff is toxic. I’m concerned that you didn’t wear a mask, or gloves. That will dry the crap out of your skin. Duct tape would work better than blue tape. I’m surprised it stuck.
