Best way to repair this cinder block damage

Hi all,

I purchased an older house 10 years ago and I'm finally getting around to fixing a few issues with the cinder blocks in the garage. In the pictures below, the wall is right before the garage door opening and against the outside porch roof, not the inside of the house directly. I'm not sure if there is really any impact in leaving it alone, but was wondering how others would try to repair this type of damage, i.e. would you tear out the cinder blockers completely and then re-cement them into place? Or would you just leave it as is?

Thanks all, Rob

About all you can do is tuck point it. Mist the blocks with water or a bonding agent first and then pack the voids with mortar mix and strike the joints smooth.

Thanks XSleeper - appreciate the quick reply. This site is great!!

Okay, that's what I was thinking as well, just fill in the gaps and tighten up the blocks. The cinder block at the front is not even tight and wobbles. Thanks!

I agree, the bigger voids will likely need 2 coats of mortar to dress it up nicely.
If a block is loose enough to remove I'd take it out and relay it or at least stuff mortar underneath it.

You will obviously want to do this when it's above 0C for an extended period of time. Anytime green concrete dips below 0C it weakens it by crystalizing the moisture that hasn't cured.
