Weekly Update: Stone Pointing

Hello Everyone,

If you’ve read last weeks news update, you know that the freeze/thaw cycle and frost heave caused a substantial amount of damage to our infrastructure. Please pay attention to your property this early spring, as you may need some, or a lot of re-pointing.

What is re-pointing? Re-pointing is when mortar is replaced between masonry units( brick, stone, block) as needed to regain integrity that may have been lost most commonly through degradation, weathering and time.

If the pointing looks brittle, loose, and flaky generally it is re-pointed before structural integrity of said structure is lost, which saves the cost and effort of rebuilding, limits property damage.

There are different types of mortar, and pointing details that serve different purposes. Here’s a few pics of various pointing details.
