Why Wait to Repair Your Stucco Until After a Foundation Lift

Orange County, and most of the Left Coast, is riddled with various kinds of expansive soil: clays, loams, silts, and more cool geological strata. Expansive soils are notorious for soaking up significant amounts of water and expanding, the soil a big earthy sponge. As the soil raises, it lifts and warps foundations due to stress.

Expansive soils are also infamous for the flipside of the coin, shrinking due to a lack of moisture. As the soil deflates, homes settle and sink into the incompetent, non-load-bearing soil. Homes rarely settle evenly, resulting in unbalanced support beneath a home’s foundation.

Signs and symptoms of foundation settlement include:

  •   Sloped floors
  •   Difficult to open doors/windows
  •   Cracked drywall
  •   Cracked stucco

For a more comprehensive explanation of the signs and symptoms above, in addition to helpful diagnostic visual aids and video content, read our article 5 Signs and Symptoms of Foundation Issues (Foundation Settlement & Foundation Heave).

Homeowners across Orange County attempt to address the symptoms of foundation settlement prior to digging down to the root of the problem. And, honestly, who wouldn’t? Cracked drywall is a major eyesore and walking across sloped floors can cause vertigo. Cracked stucco can make you look like a lazy homeowner.  

The issue with fixing cracked stucco specifically is that filler (caulk/mud) is used to fill the stucco cracks. Under normal, level circumstances, this would be the correct repair approach. However, lifting a home helps reduce the size of the cracks naturally and will push out any excess repair filler used in the initial stucco patch, resulting in the need for a second repair after the lift.

It’s best to wait until after the size of the crack has been naturally reduced by the home lift and then patch-and-paint. Or, if your home cannot be lifted, it’s still best to wait until it is stabilized (frozen in place) prior to patch-and-painting your stucco. Otherwise, your home will continue to sink and pull the patched stucco apart.

In short, when it comes to patching cracked stucco caused by foundation settlement: patience is a virtue.    

 

Simple DIY Stucco Repair Post Home Lift/Stabilization

 After your home has been lifted to maximum practical recovery or stabilized against further settlement, the stucco repair can begin.

Step numero uno is to widen the fracture (yes, trust us) about a quarter of an inch via a chisel/flathead screwdriver and hammer. It’s best to chisel out the crack at a 90-degree angle to the wall. Clear the cobwebs, dirt, and various debris out from the widened fracture.

The second step is to utilize your preferred caulk/mud, filling the crack with the repair compound. As the filler is applied, make sure to trowel the compound so it’s even with the stucco. Give the patch at least 24 hours to cure before applying paint matching the exterior of your home.

It’s best to perform a DIY stucco repair after you check your weather app and have a couple of days of sunshine.

You may notice your repair is not as firm as the surrounding stucco – this is a good thing. This elasticity allows for some play during a seismic event and prevents the patch from cracking.
