What Is Residential Stucco Repair?
Residential stucco repair encompasses crack and delamination fixes, lath replacement, moisture barrier restoration, and protective coatings. Successful restoration requires identifying the root cause of failure---such as moisture intrusion through failed joints or barriers, which triggers lath corrosion and stucco expansion. Surface patching without fixing these underlying issues causes recurring damage; proper repairs must target the moisture source.
Why South Florida Residential Stucco Fails
South Florida homes face distinct stucco failure drivers depending on their location and their age.
Salt-air lath corrosion
is the primary driver on Intracoastal-adjacent, canal-front, and barrier island homes. Fort Lauderdale's 165 miles of canals carry tidal brackish water deep into residential neighborhoods far beyond the Atlantic coastline. Lake Worth Beach sits between the Atlantic and Lake Worth Lagoon in just seven square miles, making salt-air exposure nearly universal across the city. Jupiter's Loxahatchee River carries tidal chloride significantly inland on every incoming tide. On these homes, the repair mortar must carry verified chloride diffusion resistance data. Standard inland polymer-modified mortars allow salt to continue penetrating through the repair, re-initiating lath corrosion from within.
Thermal cycling fatigue
is the primary driver on inland homes throughout Palm Beach Gardens, Royal Palm Beach, and Port St. Lucie. Daily and seasonal temperature swings cause CBS block walls to expand and contract at control joints. When joint sealant fails and is not replaced, the movement opens cracks that admit storm moisture behind the stucco face. A patch without sealant restoration produces the same crack at the same location, season after season.
Historic substrate incompatibility
is the critical third driver on pre-1940 homes in Lake Worth Beach, Delray Beach, and Stuart. Original 1920s and 1930s stucco is lime-based. Modern polymer-modified mortars are stiffer and stronger than these original substrates. When movement occurs, the original wall fails rather than the new mortar. This compressive strength mismatch causes further substrate damage with every repair cycle. Jahn restoration mortars matched to the original substrate are the only correct specification on these homes.
High water table moisture
drives base-of-wall stucco failure on homes in Royal Palm Beach, which was built on former Everglades swampland. Sustained moisture pressure at grade wicks behind ground-level stucco regardless of what is happening higher up the wall.
Signs Your South Florida Home Has a Stucco Problem
Map cracking across the stucco faces
Thermal cycling fatigue on CBS block; an open pathway for storm moisture on inland homes from Palm Beach Gardens to Port St. Lucie
Rust staining on the exterior finish
Metal lath corrosion inside the assembly; the most common warning sign on canal-front and Intracoastal-adjacent homes throughout Broward and Miami-Dade
Hollow-sounding panels when tapped
Delamination from the substrate; on canal-front homes, frequently more extensive than visible surface cracking suggests
Cracking between a previous mortar patch and original stucco
On pre-1940 homes in Lake Worth Beach or Delray Beach, this confirms incompatible modern mortar was used and the original substrate is being progressively damaged
Bubbling or blistering elastomeric coating
The protective layer has lost adhesion; the stucco beneath is now directly exposed to South Florida's salt air, UV intensity, and storm rainfall
Damp interior walls after a storm
Confirms water has moved through the stucco system and past the moisture barrier; in coastal and canal-front homes, the source may be tidal as well as storm-driven
Residential Stucco Services We Deliver
Stucco crack repair
using polymer-modified mortars and polyurethane or epoxy injection resins, specified for the home's coastal, canal-front, or inland thermal exposure zone.
Stucco delamination and hollow-panel repair
including full tap-test mapping before any material is removed, lath inspection and replacement where corrosion is present, moisture barrier restoration, and re-application in the correct coat sequence and cure times.
Lath corrosion repair and full stucco system removal and re-application
on homes where salt-air driven lath corrosion has advanced across a full elevation beyond what targeted repair can address.
Historic stucco repair using Jahn restoration mortars
on pre-1940 Mediterranean Revival, Spanish Mission, and Masonry Vernacular homes where original lime-based stucco requires material-compatible repair.
Substrate moisture barrier restoration
before new stucco is placed on older homes where the original barrier was inadequate for the salt-air or water table exposure the property actually faces.
New three-coat stucco application
over CBS block or masonry, with mix design and protective coating matched to the home's exposure zone.
Protective elastomeric coatings and penetrating sealers
as the final waterproof layer; chloride-resistant specification for coastal and canal-front homes; elongation-primary UV-stable specification for inland homes; penetrating sealer required on all Intracoastal-adjacent and canal-front completions.
Who We Serve
Anthony Pennacchi & Sons delivers residential stucco repair for homeowners across South Florida. We work on single-family CBS block homes, Intracoastal and canal-front waterfront estates, historic pre-1940 Mediterranean Revival properties, midcentury ranch homes, and newer construction showing early stucco failure from thermal cycling.
We give honest assessments. If targeted repair will hold, that is what we recommend. If lath corrosion is extensive or the moisture barrier has failed, we say so.

Our 6-Step Process
From First Call To Final Walkthrough
Every project follows the same disciplined sequence. No improvising, no shortcuts.
Free On-Site Assessment
We come to your property, examine every affected surface in person, and test for delamination and depth of deterioration before any contract is discussed.
Written Scope And Fixed-Price Proposal
We document exactly what the restoration involves and provide a fixed-price written proposal. No open-ended estimates, no surprises.
Surface Preparation
Failed material is removed to sound concrete using methods appropriate to the surface and degree of deterioration. The most common reason patches fail in South Florida is shortcuts here.
Repair And Restoration
Repair mortars, injection resins, overlays, or stucco resurfacing are applied in the correct sequence. On Mizner-era properties, Jahn mortars under our certified protocols.
Protective Treatment
The appropriate sealer or coating is applied once repairs have cured. This step closes the surface against future chloride infiltration. It is not optional in South Florida's environment.
Final Walkthrough
We walk every restored surface with the homeowner before we leave. If anything does not meet the standard we set at the start, we address it before the project closes.
The Honest Answer
Restoration Vs Replacement
Some contractors push replacement because it generates a larger contract. We do not. Here is the head-to-head.
Restoration
What we recommend in the majority of cases we assess in South Florida.
Replacement
When the substrate is gone or the structure is past saving.
We give you a straight answer after the assessment, not after looking at the size of the contract.

Frequently Asked
South Florida Stucco Repair FAQ
The questions South Florida homeowners ask most. Tap any to expand.
The tap test determines the real answer. A tap test maps the full extent of delamination across every wall face before any material is removed. On canal-front and Intracoastal-adjacent homes, delamination from tidal salt-air lath corrosion frequently extends well beyond the visible surface cracking. On older homes throughout the region, hollow panels behind apparently intact stucco faces are common on buildings that have not had a proper assessment. If the tap test confirms sound lath and substrate behind the problem area, targeted repair is the correct scope. If it reveals widespread lath corrosion or a failed moisture barrier, full removal and re-application is the only scope that delivers a lasting result.
