Stucco and EIFS Siding Replacement for Pacific Northwest Homes
If your home has stucco or EIFS siding, you’re in good company. Synthetic stucco systems have been a defining look on high-end homes throughout the region for decades, common in neighborhoods like Forest Heights in Portland, Bull Mountain in Tigard, and Prune Hill in Camas. They’re also, unfortunately, one of the siding types most likely to hide a serious moisture problem behind an intact-looking surface. Pacific Exteriors NW has been assessing, repairing, and replacing stucco and EIFS systems throughout Oregon and Washington since 1994, and we treat every one of these projects as a moisture investigation first and a siding replacement project second.
Why Stucco and EIFS Fail Differently Than Other Siding
EIFS, short for Exterior Insulation and Finish System, is a multi-layered synthetic stucco cladding, sometimes sold under names like DryVit. It was originally developed in postwar Europe as a cost-effective way to rebuild damaged buildings, and it’s been widely used on American homes since the 1980s and ’90s. The problem isn’t the material itself. It’s that traditional EIFS installations, particularly from that era, were often built as a face-sealed system with no drainage space behind them. When water finds a way past the surface, whether through a hairline crack, a poorly sealed window, or a penetration point, it has nowhere to go. It sits against the wall sheathing and framing, sometimes for years, doing damage the homeowner has no way to see from outside.
This is exactly why stucco and EIFS siding has such a well-documented history of hidden water damage and mold issues, particularly in a climate as wet as ours. A stucco or EIFS wall can look flawless and still be actively rotting behind the surface. The only way to know for certain is to open it and look, which is where we start every stucco and EIFS project, not where we end up after a problem is discovered mid-job.
What We Find Behind Stucco and EIFS Walls
When we remove failing stucco or EIFS siding, we’re often looking at conditions that have been developing for a long time: saturated sheathing, deteriorated framing, and in more advanced cases, mold growth that’s been sealed inside the wall assembly. We document what we find and walk you through it before any decision gets made about scope or budget. If the damage traces back to how the system was originally installed rather than normal wear, our construction defect repair team can help you understand your options, and our forensic building envelope consulting background means we document conditions thoroughly enough to support that conversation if it becomes necessary.
Replacement Options After Stucco or EIFS Removal
Once failing stucco or EIFS comes off and any underlying damage is addressed, most homeowners choose to move to a system with a proper drainage plane behind it rather than reinstall face-sealed stucco. James Hardie fiber cement is the most common replacement we install, offering the clean, modern look many stucco homeowners want with a drainage-plane system built in from the start. Stone and brick accents are also frequently paired with the new siding at entryways and lower-level walls where the original stucco carried architectural weight. Some homeowners choose to reinstall properly detailed stucco with a drainage cavity, and we’re happy to walk through that option if it’s the right fit for your home’s architecture.
What Homeowners Say
“My partner and I recently had Pacific Exteriors NW replace the defective stucco EIFS siding on our home. We selected new Hardie plank and trim with stone after Jay thoroughly explained our options. Honest company, even when they found dry rot.”
— Shane King, Homeowner, Stucco/EIFS Siding Replacement
“We found out that our builder had taken shortcuts and did not do a good job on the necessary waterproofing details to protect our home. Thank goodness we found Jay and his team to correct our construction defects, as these guys really do quality work.”

Common Questions About Stucco and EIFS Replacement
How do I know if my stucco or EIFS siding is failing?
Cracking, staining, or soft spots near windows and penetrations are visible warning signs, but the absence of those signs doesn’t mean your walls are dry. Because these systems can trap water invisibly, the only reliable way to know your home’s actual condition is a moisture assessment, not a visual inspection alone.
Is EIFS siding inherently bad, or is it about how it was installed?
It’s almost always about the installation. A properly detailed EIFS system with a drainage cavity and correctly integrated flashing can perform well. The widespread problems associated with EIFS in the Pacific Northwest largely trace back to older, face-sealed installations that never had anywhere for water to go once it got past the surface.
Do I have to replace all my stucco, or can problem areas be repaired?
It depends on how contained the moisture damage is. Isolated damage near a single window or penetration point may be repairable. Widespread moisture behind large sections of wall usually points toward a full replacement being the more responsible long-term choice. We won’t know which situation you’re in until we assess it directly.
Will this be covered by my homeowners insurance or a builder warranty?
It depends on the cause and the age of your home. Construction defect claims tied to original installation may fall under a builder’s warranty or, in some cases, litigation, particularly if the defect is widespread across your neighborhood. We can help you understand what you’re looking at, though we’d recommend involving a construction attorney for anything that looks like a builder-wide issue.
