Find Stucco Repair & EIFS Moisture Remediation Specialists for 30A Coastal Homes

Hairline cracks and stained stucco are often the only visible sign that water has been getting into the wall for months. We connect you with independent, qualified local contractors who find where the water is getting in, repair the wall behind the finish and match the texture so the repair disappears.

The coastal problem

Why stucco fails faster on the Gulf

Wind-driven rain off the Gulf pushes water sideways into every crack, window corner and penetration. Stucco absorbs some water by design, but airborne salt comes in with it and corrodes galvanized lath, weep screeds and corner beads from inside the wall.

Constant humidity means walls rarely dry out between storms. On frame-built upper floors, moisture trapped behind the finish can rot sheathing and framing long before anything shows inside, and that damage costs far more to fix than the stucco does.

Warning signs we see on 30A properties

  • Cracks radiating from window and door corners
  • Rust stains or bleeding at the base of walls
  • Bubbling, blistering or soft spots in the finish
  • Staining or efflorescence below windows and sills
  • Swollen trim, sticking doors or musty interior odors
  • Old patches that don’t match or keep re-cracking

What good work looks like

What a proper repair should include

Use this as a checklist when you compare contractor proposals. The independent contractors we refer you to set their own scope, pricing and warranty terms.

Traditional Three-Coat Stucco

Portland-cement stucco is applied as scratch, brown and finish coats over metal lath on frame walls, or directly over block. Repairs range from isolated cracks to full-elevation tear-offs, and good contractors follow the ASTM C926 and C1063 standards.

A complete scope should cover

  • Crack routing, cleaning and repair with compatible materials
  • Removal of delaminated or hollow-sounding sections
  • Replacement of corroded lath, weep screeds and casing beads with coastal-rated accessories
  • New weather-resistive barrier and flashing integrated at openings
  • Rebuilt scratch and brown coats with proper cure time between coats
  • Finish coat matched to the existing texture and color

EIFS Moisture Remediation

EIFS (synthetic stucco) looks like traditional stucco but handles water very differently. Older face-sealed “barrier” EIFS has no way to drain water that gets behind it. A specialist maps the wet areas, then remediates the wall or converts it to a drainage system.

A complete scope should cover

  • Non-invasive scanning, then moisture-probe testing at high-risk locations
  • Probe map and photo report of wet and damaged areas
  • System removal and replacement of wet or rotted sheathing
  • Re-detailed window flashings, kick-out flashings and terminations
  • New drainage EIFS, or conversion to three-coat stucco
  • Every penetration sealed and flashed

Elastomeric Coatings

High-build elastomeric coatings flex over hairline cracks and shed wind-driven rain. Applied over a wet wall, though, they can trap the moisture inside. A careful contractor tests first and only coats walls that are dry and sound.

A complete scope should cover

  • Substrate moisture testing before any coating
  • Fresh-water wash to remove salt, chalk and mildew
  • Hairline cracks pre-treated and bridged
  • Primer selected for the substrate
  • Two coats at the manufacturer’s specified film thickness
  • Breathable or elastomeric system chosen to suit the wall

Control Joint Sealing

Control and expansion joints, along with the transitions at floor lines, tie beams and changes in material, are where stucco is designed to move. When the sealant in those joints fails, water goes straight into the wall.

A complete scope should cover

  • Failed or hardened sealant cut out
  • Joint faces cleaned and primed
  • Backer rod sized to the joint
  • High-performance sealant at the correct width-to-depth ratio
  • Window perimeters, fixtures, hose bibs and penetrations sealed
  • Sealant tooled and color-matched to the finish

If damage is found behind the wall

Rotted sheathing or framing often turns up once a wall is opened. Ask your contractor up front how they handle it. Good contractors photograph hidden damage and get your approval on the added cost before continuing, and they bring in a licensed engineer when structural repair is needed.

What to expect

How a typical project runs

After we connect you, the contractor you choose handles the project. Here’s what a well-run job typically looks like.

  1. 1

    Inspection & moisture testing

    The contractor surveys every elevation and takes moisture readings at windows, doors, penetrations and roof-to-wall transitions.

  2. 2

    Documented findings

    A good inspection ends with a photo report, a moisture map, the likely entry points and a prioritized scope you can forward to an owner, HOA or insurer.

  3. 3

    Remediation

    The cause gets fixed first (flashing, lath, barrier and sheathing), and then the stucco or EIFS system is rebuilt.

  4. 4

    Finish match

    Texture and color are matched so the repair blends into the original wall.

  5. 5

    Close-out

    Expect before-and-after photos, a record of materials used and written warranty terms from the contractor.

Questions to ask any contractor

  • Will you moisture-test before recommending a repair?
  • Is this traditional stucco or EIFS, and how did you confirm it?
  • How will hidden damage be priced and approved?
  • Will the repair be texture- and color-matched, or should the whole wall be refinished?
  • What written warranty do you provide, and what does it cover?
  • Will you pull the permit under your license if one is required?

FAQ

Common questions

Can the crack just be patched?

Sometimes. A shrinkage crack in otherwise dry, sound stucco can be routed, filled and refinished. If moisture readings around the crack are high, though, a patch only hides the problem. A good contractor tests before recommending either.

How do I know if my home has EIFS or traditional stucco?

EIFS usually sounds hollow when tapped and feels softer, sometimes flexing slightly under pressure. Traditional stucco is hard and solid. A contractor can confirm it during an inspection, typically at a light fixture or other penetration.

Do I need to be home for the inspection?

Usually not. Many 30A owners live elsewhere, and many local contractors are used to arranging access through the owner or property manager and emailing a photo report. Tell us your situation and we’ll pass it along.

Does South Walton Exteriors do the repair?

No. We’re a free referral service. We connect you with an independent, qualified local contractor, who inspects, quotes and, if you hire them, does the work under a contract directly with you.
