Full stucco remediation by a team that understands the difference between treating the symptoms and solving the problem
Stucco repair fixes what you can see. A contractor fills the cracks, patches the damaged sections, refinishes the surface, and the house looks fine — if an underlying water-entry problem is left unresolved, the surface work alone will not correct it.
Stucco remediation fixes what caused the problem. That means stripping the stucco to the sheathing, finding and addressing the water damage underneath, correcting the flashing and moisture management deficiencies that allowed water in, replacing compromised structural materials, and reinstalling a system designed to manage water and protect the repaired structure.
These are not the same job. The scope should address the diagnosed cause, not just the visible surface.
KLM does remediation.
Stucco itself is not a waterproof material. It's a cladding system that relies entirely on what's behind it — the moisture barrier, the flashing details, the window and door integration — to keep water out of the structure. When part of that system fails, water can reach the materials behind the stucco and remain concealed without an obvious surface sign.
By the time stucco failure is visible — cracking, bulging, efflorescence, soft spots — there may also be damage within the framing, sheathing, and/or insulation behind it. In many cases, the homeowner is looking at the final stage of a problem that started years earlier.
The most common entry points:
Window and door flashing. Improperly integrated window and door flashing is a potential source of water intrusion behind stucco. In many of the homes we work on, the original installation missed the flashing details that make the window-to-wall connection watertight. Water follows the frame and saturates the rough opening framing for years before it announces itself.
Penetrations and transitions. Hose bibs, electrical outlets, light fixtures, corners, roofline transitions — every point where the stucco system meets another element is a potential failure point. Each one requires specific flashing treatment. Missed or inadequate details at any of them are an invitation for water.
The stucco system itself. If a wall lacks an effective drainage path or has defective water-management details, moisture that passes the outer surface may remain in contact with vulnerable materials. The assembly and extent of damage need to be assessed to establish the appropriate scope.
You may not see obvious stucco failure and still have active water intrusion. Look for:
These are warning signs, not proof of hidden water damage. An assessment should establish the likely cause and whether further investigation behind the cladding is needed.
A visual review can identify cracking, staining, failed details and other reasons for concern, but it cannot reveal every concealed condition. Depending on the building and symptoms, further investigation may involve moisture testing or selective openings by a qualified professional. Ask who would perform that work, what it can establish and how any openings would be restored.
KLM’s service is full remediation of the underlying problem. A localized repair can be appropriate for some buildings, but that is different from covering up symptoms where the wall’s water-management system or structure needs correction.
These are different wall assemblies. Traditional cement stucco is not the same product as an exterior insulation and finish system, or EIFS. Older barrier EIFS and modern EIFS with drainage also should not be treated as identical. Drainage EIFS includes a water-resistive barrier and a path for incidental moisture to escape.
The actual construction and defects determine the investigation and remediation scope. Stucco, drainage EIFS and fiber cement all depend on correctly integrated details around openings and transitions. See the EIFS Industry Members Association’s assembly explanation.
Full stucco remediation is a multi-phase project. Each phase requires specific expertise, and each one has to be completed correctly before the next can begin. This is why we use specialized crews for each stage of the work rather than running a single team through the entire project.
Scaffolding and access. Before anything comes off, proper scaffolding is installed. Access to the full exterior isn't a nicety — it's how you ensure every section gets the same attention and nothing gets skipped because it was hard to reach.
Stucco removal. The existing stucco comes off. All of it, not just the sections that look damaged. Water damage behind stucco does not respect the boundaries of the visible failure.
Structural assessment and documentation. This is the phase most homeowners are unprepared for — and the one that matters most. As the sheathing is exposed, we document every area of rot, mold, and structural compromise with photographs. You see exactly what was found and where. Nothing is covered up or glossed over. If the damage is more extensive than expected, we stop, show you, and get your approval before proceeding.
Structural repair. Rotted sheathing, compromised band boards, damaged framing — all of it is replaced to solid material before anything goes back on. The moisture barrier and drainage plane are installed correctly over repaired structure.
Window and door removal and reinstallation. In KLM’s full remediation process, window removal and reinstallation provides access to address the window-to-wall connection. The required scope depends on the opening, existing assembly and defects found. We reinstall windows with correct flashing integration sequenced into the new weather-resistive barrier.
New cladding installation. With the structure repaired and the moisture management system in place, the new exterior goes on — most often James Hardie fiber cement siding, installed over the repaired structure with appropriate flashing and water management. Trim, detailing, and finish work are completed by the appropriate specialized crew.
Paint and finish. Final exterior paint by a dedicated painting crew, not the siding crew working overtime.
Compare the wall area, access and scaffolding, removal and disposal, window and door scope, structural repairs, new cladding and finish details. Concealed damage is a particular source of uncertainty. The proposal should explain what is known, what remains to be established and how additional work will be documented and approved.
A low surface-repair price and a full-remediation proposal may cover very different work. Compare the cause each proposal addresses and the water-management details included, rather than price alone.
Discuss whether existing windows can be reused or whether replacement windows belong in the scope. The opening and surrounding wall must work together. For the finish, review James Hardie siding and other siding options, trim proportions and colors as a complete design.
Agree on access, parking, material staging, dust and debris controls, pets and children, and how exposed areas will be protected as the work progresses. Duration depends on the building, findings, approvals and weather. Ask for the project sequence and how changes will be communicated.
Keep the proposal, approved changes, photographs of exposed conditions and repairs, product information and applicable warranties. These records help explain what was found and corrected, including when a future buyer asks about the exterior. They do not establish a guaranteed resale price.
Coverage depends on the policy, cause of damage and insurer’s assessment. Consult your insurer about your circumstances and its documentation requirements before assuming coverage or reimbursement.
A properly remediated home is a different thing from a patched one. The structure is sound. The moisture management system works the way it was supposed to from the beginning. The new exterior is a material that performs in this climate without the ongoing maintenance liability of stucco.
And it looks, in the words of more than one client, better than new.
We've also seen what remediation does to home value. The difference between a stucco home with known moisture issues and one with a professionally remediated exterior and James Hardie cladding is not a small number. Addressing documented moisture issues can improve a home’s condition and appeal to buyers. Resale results vary with the property, project scope, and market; recovery of the remediation cost is not guaranteed.
We know the difference between repair and remediation — and we won't pretend they're the same. We've seen what happens when water intrusion behind stucco is patched rather than solved. We don't offer that service. If your home needs remediation, we'll tell you, show you what we found, and do the work correctly.
Specialized crews for each phase. Scaffolding, demolition, structural repair, moisture barrier, window reinstallation, siding, trim, and paint — each phase is handled by a crew trained for that specific work. This is not a single team working through the list. It's the reason the finished product looks and performs the way it does.
Complete documentation throughout. We photograph the damage as it's found. You know exactly what was in your walls, what was done about it, and why. No guesswork, no surprises after the fact.
James Hardie Elite Preferred. The most common outcome of a remediation project is an exterior that outperforms the original in every respect. As a James Hardie Elite Preferred installer, we replace stucco with a material engineered for long-term performance in this climate, backed by the applicable limited manufacturer warranty, subject to its written terms and exclusions.
