What We Restore

Surfaces We Repair At Palm Beach Homes

Pool decks to foundation walls. Every primary residential caulking surface.

Window And Door Perimeters

Most common

The 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.

Siding And Trim Joints

Horizontal and vertical joints between siding panels, trim, and transitions.

HVAC Penetrations And Flashings

Sealant around every pipe, vent, or mechanical penetration through the roof or walls.

Method 01 of 05

Joint Assessment And Sealant Selection

SpecPer-joint specification

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 Palm Beach. We specify based on the conditions each surface actually faces.

M01

High-Movement Polyurethane Sealant

Dynamic joints

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.

M02

Marine-Grade Silicone Sealant

Coastal + UV exposure

For salt-air exposure, pool decks, and any coastal property. UV-stable and chloride-resistant where polyurethane degrades.

M03

Hybrid MS-Polymer Sealant

Paintable + UV-stable

Hybrid polymer sealants that can be painted over. Ideal for stucco cracks and decorative trim joints where a painted-over finish is required.

M04

Closed-Cell Backer Rod

Joint depth control

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.

M05

Historic-Compatible Sealants

Period-appropriate chemistry

For Mizner-era and historic district properties, we use sealants with appearance and chemistry compatible with original masonry and stucco.
