What We Do When Mold Grows Under Stucco

November 21, 2016

Moldy exterior removed from a homeStucco has a tendency to get mold behind it, and repairs can cost many tens of thousands of dollars. Unfortunately, many homes in the Philadelphia suburbs were built using stucco.

If you have stucco, you can be fairly certain that it will get moldy eventually. It’s probably best to replace it before the mold grows in since failing to act quickly can result in expensive bills. Just ask this local couple. When trying to sell their house, their buyer backed out after a stucco inspection found that their home needed $70,000 to $120,000 worth of work to correct the compromised walls. Some experts say that stucco homes as new as 10 years can have mold damage repairs costing $200,000+.

Fortunately, moldy walls can often be saved in a process called stucco remediation. In most cases, the sooner you act, the easier it will be to fix.

Over the summer, we aided a homeowner in remediating their stucco walls. They called us when they noticed cracks in their foundation, which is a tell-tale sign that there is mold growing underneath. Other indicators include black streaks, cracks, and gaps, which tend to occur around windows and other penetrations in your walls.

Our Stucco Remediation Process

  1. rot and mold under stoneRemove Stucco. The first thing we do is remove the stucco, along with any nails and wires holding it on. Then, we thoroughly clean the wall to prepare for the next steps.
  2. Remove Damaged Plywood Sheathing. After the stucco is out of the way, we remove any plywood sheathing underneath that has been damaged. Remember, mold spreads, so it’s important that we gut out any of the mold that clings onto the structure.
  3. Remove Damaged Structural Components. Next, we remove any structural components of the wall that have been compromised by mold. This ensures that the mold has been eliminated in its entirety.
  4. Install New Flashing. We need to remove the windows and doors and install new flashing. Windows and doors tend to be where the mold is able to seep into the stucco.
  5. Install House Wrap. Installing house wrap is probably the most important step in the process. It’s one of the main things protecting your home from moisture. We also need to apply flashing tape around every wall penetrations, including windows, doors, pipes, and hose bibs.
  6. Install New Siding. The final step is installing the new siding. We offer several different types of cladding to choose from, including Hardie board fiber cement siding and insulated vinyl.
