Our Repair Promise

Tailored Stucco Repair — Not Unnecessary Teardowns

We see homeowners pressured into full envelope teardowns for damage that’s actually localized. Our standard is the opposite — we only recommend the wall work the diagnosis actually requires.

If the wall reads dry and sound, we say so. If moisture has reached the substrate, we map the damaged section, show you the readings, and quote only the area that has to be opened and rebuilt.

Free Diagnostic Tool

non-destructive moisture inspection

Every stucco water damage assessment includes a non-destructive moisture scan, so we’re not guessing where water is hiding.

Non-Destructive Scanning

We use our non-destructive moisture scanner to detect water concentrations behind the plaster without drilling or damaging your exterior walls.

Precise Moisture Mapping

Confirms whether the paper, lath, and framing are actually wet — so the repair scope is based on exact moisture readings, not a guess.

Moisture Diagnosis

Common Causes of Stucco Moisture Intrusion

Stucco is a layered wall system. The finish is only the visible part. A proper water damage repair checks the path water used to enter, where it traveled, and whether the wall can drain after the repair.

Window and flashing leaks

Water often enters around window corners, roof-wall transitions, decks, or poorly sealed penetrations.

Lower-wall drainage failure

Buried stucco, soil against the wall, or rusted weep screed can trap water at the bottom of the wall.

Cracks and failed patches

Cracks, old caulk, and surface patches can let water in or seal moisture inside the wall.

Repair Process

Our Stucco Water Damage Repair Process

Find the water path

We inspect cracks, window edges, roof transitions, weep screed, grading, sprinklers, and staining patterns before recommending a repair.

Open only what needs to be opened

When damage looks deeper than the finish coat, we expose the failed section so the paper, lath, sheathing, and framing can be checked.

Replace failed wall materials

Damaged paper, rusted lath, rotten sheathing, failed flashing, or lower-wall drainage issues are corrected before new stucco goes back on.

Rebuild and blend the finish

The repair is rebuilt in proper layers, cured, and finished with a realistic texture and color-match plan for the existing wall.

Cost Factors

Stucco Water Damage Repair Cost Factors

Water damage pricing depends on how far the moisture traveled. A small finish stain is different from a wall section that needs new paper, lath, sheathing, flashing, or lower-wall drainage repair.

Size of the damaged area

Whether the wall must be opened

Paper and lath condition

Dry rot or sheathing repair

Window or flashing involvement

Weep screed or drainage work

Texture and color matching difficulty

Access, height, or scaffolding

FAQs

Stucco Water Damage Repair FAQs

Can water damaged stucco be repaired?+

Yes, but the repair has to address the source of the water first. If only the finish coat is stained, a surface repair may be enough. If the paper, lath, sheathing, or framing is wet or rotten, the damaged section needs to be opened, rebuilt, and finished correctly.

How do I know if water is behind my stucco?+

Common signs include bulging stucco, soft or hollow areas, rusty stains, white efflorescence, bubbling paint, recurring cracks, musty smells near an exterior wall, or damage concentrated below windows and at the bottom of the wall.

What causes stucco water damage?+

The most common causes are failed window flashing, roof or deck flashing leaks, buried or rusted weep screed, cracked stucco, sprinkler overspray, soil or mulch against the wall, and old patch repairs that trapped moisture instead of fixing it.

Should I paint or seal water damaged stucco?+

No. Paint or elastomeric coating can trap moisture inside the wall if the underlying system is already wet. The wall should be inspected first so the damaged material and water path can be corrected before any finish or coating is applied.

How much does stucco water damage repair cost?+

Small surface repairs can be relatively limited, but full-depth water damage repairs cost more because they may include paper, lath, sheathing, framing, weep screed, flashing, and texture matching. The exact price depends on the size and depth of the damage.

Is stucco water damage covered by insurance?+

Sudden storm or impact damage may be covered, but gradual moisture intrusion, failed maintenance, buried weep screed, or long-term leaks are often excluded. We provide photos and a written scope so you can discuss the issue with your carrier.
