What We Restore
Surfaces We Repair At Delray Beach Homes
Pool decks to foundation walls. Every primary residential caulking surface.

Most commonThe joint between the window frame and the building exterior. Most critical water entry point on any home.
Expansion Joints
Joints that accommodate thermal movement in driveways, pool decks, patios, and stucco facades.
Stucco Cracks
Hairline and larger cracks in stucco that allow water into the wall assembly.
Pool Deck Perimeter Seals
The joint between the pool shell and the surrounding deck slab. Critical for preventing soil erosion.

Technical Methods

Joint Assessment And Sealant Selection
We inspect every joint, identify existing sealant chemistry (polyurethane, silicone, hybrid), measure joint width and movement, and specify the correct replacement product for each joint type. One-size-fits-all is a common reason installations fail.
Materials We Specify
Built For South Florida Exposure
A repair mortar that performs in a northern state may fail within a year in Delray Beach. We specify based on the conditions each surface actually faces.
High-Movement Polyurethane Sealant
For joints with high thermal or structural movement: expansion joints, window perimeters on high-rise buildings, control joints. Elongation rated for 25 to 50 percent joint movement.
Marine-Grade Silicone Sealant
For salt-air exposure, pool decks, and any coastal property. UV-stable and chloride-resistant where polyurethane degrades.
Hybrid MS-Polymer Sealant
Hybrid polymer sealants that can be painted over. Ideal for stucco cracks and decorative trim joints where a painted-over finish is required.
Closed-Cell Backer Rod
Properly sized closed-cell backer rod controls sealant depth and creates a three-sided bond profile. Essential for any joint over 1/4 inch wide.
Historic-Compatible Sealants
For Mizner-era and historic district properties, we use sealants with appearance and chemistry compatible with original masonry and stucco.

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 Delray Beach.
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
Delray Beach Caulking FAQ
The questions Delray Beach homeowners ask most. Tap any to expand.
Downtown Delray Beach's Atlantic Avenue has structures from the 1920s through 1950s with lime-based stucco and vintage glazing. Applying modern products directly to aged lime stucco causes adhesion failure within months. We assess substrate composition on every historic district project and select chemically compatible systems that bond without damaging original materials.
