How is remediation different from a stucco repair?

A repair rebuilds the stucco. Remediation rebuilds the wall assembly behind it, including the weather-resistant barrier, the flashing, and any damaged sheathing or framing. If the substrate is dry and sound and only the plaster failed, you need a repair. If water has been sitting behind the wall long enough to damage what is back there, patching the outside just hides an ongoing problem.

Do you have to remove all the stucco on the house?

Not usually. Probe testing exists specifically so we can define the wet areas and remove only what needs to come off. Full removal becomes the sensible route when the damage is widespread across most elevations, or when the underlying barrier and flashing were installed wrong everywhere, in which case selective work would just leave you with the same failure next to the new work.

Can I remediate only the one wall that has a problem?

Often yes, and that is frequently the right call. Water damage tends to concentrate where the details are worst, so a single elevation getting the brunt of wind-driven rain can be far worse than the other three. We probe all sides before recommending a single-wall scope, because finding the same conditions elsewhere changes the plan. Bear in mind that a newly finished elevation will not match the sun-faded ones next to it without coating.

How do you know the wall is dry enough to close up?

We take meter readings of the exposed sheathing and framing and keep drying until they come down to a stable, acceptable level rather than closing on a schedule. Readings get taken over more than one day, because a surface can read dry while the core is still wet. Closing a wall early is the one mistake in this process you cannot see afterward and cannot undo without opening it again.

Will homeowners insurance cover stucco remediation?

That depends entirely on your policy and on the cause, and we are not the right people to tell you what your coverage says. In general, sudden and accidental damage tends to be treated differently from long-term water intrusion or construction defects. What we can do is give you thorough documentation, including moisture readings, probe locations, and photographs of the open wall, which is what any claim or dispute will turn on. Talk to your carrier or a public adjuster about the coverage question itself.

Remediation is not just a larger repair

A repair addresses the stucco. Remediation addresses the wall. The distinction matters because the two jobs answer different questions. A repair asks how to make this section sound and invisible again. Remediation asks what path the water took to get in here, what it damaged on the way, and what has to change so it does not happen a second time.

The stucco itself is frequently the last thing that failed. On a framed wall the usual culprit is upstream of the plaster entirely: a window that was never properly flashed, a kickout flashing that was left off where a roof edge meets a wall, a deck ledger, a torn or reverse-lapped weather-resistant barrier. Water enters at a detail, runs down the back of the drainage plane, and finds somewhere to sit. By the time it shows on the outside, the sheathing behind it has often been wet for years.

The investigation comes before the demolition

We start non-invasively. A surface scanning meter reads relative moisture across an elevation and lets us map where the wet areas are without putting a single hole in the wall. Those readings are comparative rather than absolute, so we use them to narrow the search, not to draw conclusions.

Then we probe. Small holes drilled through the stucco let a pin meter read the actual moisture content of the sheathing or framing behind it. Probes go at the places water is most likely to collect: below window sills, at the corners of openings, at roof-to-wall transitions, at penetrations, and low on the wall near the base. We record what each probe reads and where it was taken, so what comes next is based on data instead of a guess. Every probe hole gets patched and sealed the same day.

Opening the wall and rebuilding the assembly

Once the scope is set, the stucco and lath come off in the affected areas and we get to see the truth. Sheathing that is soft, delaminated, or blackened comes out. Framing gets probed and evaluated. Anything structural that is compromised gets identified and addressed before the wall closes back up, and if it is beyond a siding contractor's lane we will say so rather than plaster over it.

Rebuilding runs in the reverse order of failure. New sheathing where it was needed. A continuous, correctly lapped weather-resistant barrier that sheds water down and out rather than into the wall. Flashing corrected at every opening and transition that contributed to the problem, including the kickouts that were missing. Then new lath, then the coats, then the finish. If the drainage detail does not get fixed, the new stucco is just a fresh surface over the same failure.

Selective demolition of stucco and lath in the affected areas
Removal of rotted or delaminated sheathing
Drying of the cavity and remaining framing before anything is closed in
New weather-resistant barrier, lapped shingle-style so water drains out
Corrected flashing at windows, doors, roof-to-wall junctions, and penetrations
New lath, new three-coat stucco, and a finish blended to the rest of the house

Why remediation scopes vary so widely

There is no useful average price for this work, and anyone who quotes one over the phone is guessing. Two houses of identical size can be an order of magnitude apart in cost depending entirely on how long the water has been in the wall and how far it spread before anyone noticed.

Scope is also affected by what else has to move. Windows sometimes have to come out to flash them properly. Trim, shutters, downspouts, light fixtures, and pool cage attachments all get removed and reset. Interior finishes occasionally have to be opened where damage came through. The stucco line item is often not the largest number on the page.

Why this climate makes moisture problems worse

In a dry climate, a wall that gets wet gets a chance to dry out between events. Here it often does not. Ambient humidity stays high enough for long enough that a cavity holding water simply stays damp, and damp wood is what rot needs. That is why a leak that would be a slow nuisance elsewhere becomes structural damage on the Treasure Coast.

Wind-driven rain is the delivery mechanism. Rain arriving nearly horizontally is pushed into gaps that would never see water from a vertical drip, and it gets forced upward under laps and terminations. During storm season a wall can take on more water in a single afternoon than it would in months of ordinary weather. Add salt to that moisture and any embedded metal in the assembly starts corroding at the same time.

What you might notice before we do

The exterior signs are the ones people usually catch first. Staining that keeps coming back through fresh paint. A chalky white bloom on the surface, which is efflorescence and means water is moving through the wall and depositing salts as it evaporates. Bulging or soft areas. Stucco that crumbles when you press it near the base of a wall.

The interior signs get missed more often, and they are the ones that tell you the problem is already past the stucco. Baseboards that have separated or cupped. A musty smell in one room and nowhere else. Drywall that feels soft below a window. Paint or wallpaper lifting on an exterior wall. Any of those on an outside wall is worth a probe test before it becomes a bigger project.

Protecting yourself on a remediation project

Insist on documentation. Probe locations, moisture readings, and photographs of what was found once the wall was open should all be handed to you. That record is what proves the work was necessary and what proves it was done, and you will want it if you ever sell the house.

Be skeptical of a fixed price quoted before any probing has happened. Nobody can know the extent of hidden damage from the outside of a wall, and a firm number offered without investigation usually means the unknowns get billed to you later anyway. A scope written in phases, with an agreed unit price for additional damage found, is more honest and usually cheaper in the end. Also make sure someone has taken responsibility for the flashing details, because that is where the job either succeeds or repeats itself.
