Residential Waterproofing in Jupiter
Jupiter Inlet creates brackish tidal vapor that penetrates inland far beyond what homeowners expect. Marine-rated waterproofing systems, Loxahatchee River exposure specifications. assessment. Jupiter's flood hazard areas are so scattered the Town's own documentation states every property has flooding potential. Salt-air A1A homes, Loxahatchee riverfront estates, 1980s CBS construction in Jupiter Village, and canal-front Admiral's Cove properties all face different conditions. Anthony Pennacchi & Sons has waterproofed residential properties across South Florida since 1947.

Why Restoration Over Replacement
Why This Makes Sense For Jupiter Homeowners
Tap any reason to expand.
Exterior waterproofing is a fraction of the cost of gutting and restoring water-damaged drywall, flooring, and cabinetry.
Waterproofing stops chloride and moisture from reaching structural steel inside concrete and masonry.
Properly waterproofed exteriors last 15 to 30 years between intervention.
Dry walls do not grow mold. Waterproofing is the root cause intervention.
Most waterproofing scopes are completed externally without entering the living space.
Every project comes with a written warranty. We come back to correct any failure.
Catch It Early
Six Signs Your Waterproofing Needs Attention
Jupiter properties along the A1A corridor and Loxahatchee River face brackish vapor exposure twice daily from tidal flushing.
Brown stains, bubbling paint, or discolored drywall near exterior walls is water entering the envelope.
White salt deposits on brick, block, or stucco exteriors indicate water is moving through the wall.
Black or green spots on walls near exterior faces is moisture that should not be there.
Paint failure on exterior walls often indicates water trapped behind the coating.
Unsealed cracks in stucco or masonry become direct water entry paths into the wall assembly.
Standing water or persistent moisture at the slab edge, along ground-level walls, or where the foundation meets the soil.

Technical Methods
How We Actually Do The Work
The details that separate a 30-year repair from one that fails next wet season. Click any method to see how it works in Jupiter conditions.
Moisture Source Diagnosis
Before specifying a waterproofing system, we diagnose where water is actually entering. Chasing visible symptoms without finding the real source is the most common reason waterproofing jobs fail.
Materials We Specify
Built For South Florida Exposure
A repair mortar that performs in a northern state may fail within a year in Jupiter. We specify based on the conditions each surface actually faces.
Silane-Siloxane Penetrating Sealers
Block water at the pore level without changing the appearance of the wall. Appropriate for stucco, brick, masonry, and concrete walls.
High-Build Elastomeric Coatings
Waterproof, UV-stable, crack-bridging membrane. Ideal for stucco walls with hairline cracking.
Self-Adhering Sheet Membranes
For below-grade foundation walls. Continuous waterproof barrier installed behind backfill.
Fluid-Applied Waterproofing
For surfaces with penetrations, changes in plane, and complex geometry. Monolithic membrane without seams.
Traffic-Grade Waterproof Coatings
Pedestrian-rated waterproofing for balconies, patios, and pool decks.
Our 6-Step Process
From First Call To Final Walkthrough
Every project follows the same disciplined sequence. No improvising, no shortcuts.
On-Site Assessment
We diagnose moisture source, scope the surfaces that need waterproofing, and specify the right system per surface.
Written Scope And Fixed-Price Proposal
Every surface listed, every system specified. Fixed price.
Surface Preparation
Substrate cleaned, cracks repaired, prime as specified by the manufacturer for each system.
Waterproofing System Installation
System applied to manufacturer specifications including thickness, coverage, and cure.
Protective Top Layer
Top coat, aggregate broadcast, or backfill as specified for the system.
Water Test And Final Walkthrough
Water-test critical areas (balconies, below-grade) before sign-off.
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 Jupiter.
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
Jupiter Waterproofing FAQ
The questions Jupiter homeowners ask most. Tap any to expand.
The Town of Jupiter's official flood documentation states that because its flood hazard areas are scattered throughout the town rather than concentrated in a single zone, every property has flood potential. This reflects Jupiter's unique geography: the Loxahatchee River runs through residential neighborhoods, the Jupiter Inlet connects the ocean to the Intracoastal Waterway through the middle of town, and low-lying areas along canals and lakes exist across most of Jupiter's residential sections. For homeowners, this means that regardless of your FEMA flood zone designation, a waterproofing assessment that establishes the specific moisture conditions at your property is the right starting point.
The answer depends on where your property sits relative to Jupiter's three water systems. If moisture is appearing at or below grade level, through interior staining at a consistent height, efflorescence on lower exterior block, or a recurring damp smell at ground floor, the moisture source is most likely below-grade. Applying an elastomeric coating to the above-grade surface will not address tidal groundwater pressure acting on the foundation wall from the Loxahatchee or Intracoastal side. Foundation waterproofing in Jupiter typically involves excavation, drainage board installation, and membrane application to the exterior face of the foundation wall, sometimes combined with interior drainage for riverfront and canal-front properties. The assessment establishes which applies at your specific property.
Yes. Jupiter has a range of older residential properties, including wood-frame homes along the Loxahatchee River and Riverside Drive areas that predate CBS construction standards. Our Certified Jahn Applicator status means we can specify substrate-compatible waterproofing systems that protect these properties without damaging or trapping moisture behind the original building fabric. On older and timber-frame structures, breathable penetrating systems are often preferable to film-forming coatings. We assess substrate type and condition before specifying any system on a property where age or construction method makes compatibility a factor.
Above-grade penetrating sealer or elastomeric coating on a single elevation typically completes in one to two days. A full exterior treatment across all elevations of a mid-sized Jupiter home usually runs two to four days depending on surface area and preparation requirements. Below-grade systems involving excavation, membrane installation, and drainage board are a larger scope, typically five to ten days for a single foundation wall and longer for full-perimeter treatment. Every written proposal includes a timeframe.
Yes. Florida law requires a licensed contractor for waterproofing work on residential properties. Anthony Pennacchi & Sons holds contractor licenses in Florida, New Jersey, New York, and Pennsylvania. Always request written evidence of licensing and insurance before engaging any contractor. Unlicensed work can void homeowner's insurance coverage and create liability in the event of a system failure.
Call us at (561) 475-0775 or request an on-site assessment through pennacchiindustries.com. We visit the property, trace the moisture source, and produce a written, fixed-price proposal. There is no obligation and no cost for the assessment. For Loxahatchee River-adjacent properties, canal-front homes in Admiral's Cove or Jonathan's Landing, or any property in Jupiter's documented flood zones, let us know before the site visit so we can prepare accordingly. Anthony Pennacchi & Sons, 2875 South Ocean Blvd., Suite 200-18, Palm Beach, FL, (561) 475-0775.
