Repair or Replace Concrete Steps?
The very best way to fix concrete steps
is to demolish the old ones and pour
new ones. No repair lasts forever. And
replacement is the only real fix for
steps that are sinking or have deep
cracks. But if your steps are level and
have only the usual damage that goes
a few inches deep, you can save yourself
a ton of money and/or labor by
patching or recapping them.
Patching works well for small, shallow
chips and cracks (less than 1/4 in.
deep). Simply fill them with premixed
concrete patching material. To patch
cracked corners, chisel them out to a
depth of at least 3/4 in. Then drill
holes and drive in concrete screws as
anchors, apply a bonding adhesive and
fill with crack-resistant concrete. The
patch won’t match the color or texture
of the steps, so you may want to
recoat all the steps with concrete
resurfacer for a uniform look.
If the cracks or voids extend over
large areas of your steps, forget about
patching. Go ahead and cap the steps
following the procedure shown here.
