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 Boynton 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 Boynton 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
Boynton Beach Caulking FAQ
The questions Boynton Beach homeowners ask most. Tap any to expand.
Most commercial buildings along Congress Avenue and Boynton Beach Boulevard were built between 1980 and 2005 using first-generation polyurethane sealants rated for 10 to 15 years. These materials are now 20 to 40 years old and show complete adhesion loss, deep cracking, and total loss of elasticity across the building envelope.
