Caulking & Sealant Systems
Protecting Buildings from the Elements

System 6 specializes in commercial sealant installation, replacement, and restoration for buildings of all sizes. Our services include perimeter window and door caulking, expansion joint sealants, traffic-grade horizontal joints, landscape sealants, and complete building envelope restoration. Every system is selected based on joint movement, substrate compatibility, weather exposure, and long-term performance requirements.

Perimeter sealants create a flexible weatherproof barrier around windows, doors, curtain walls, EIFS, masonry, precast concrete, and metal panels. Properly installed perimeter caulking helps prevent water infiltration, air leakage, heat loss, and premature deterioration of the building envelope while accommodating normal building movement.

Most commercial sealant systems have a service life of approximately 10 to 25 years depending on the sealant type, joint movement, UV exposure, weather conditions, and installation quality. Regular inspections help identify failing sealants before water intrusion causes more costly building repairs.

Expansion joints are intentional gaps designed to allow buildings and materials to expand, contract, and move without causing structural damage. Flexible sealants bridge these joints while maintaining a watertight seal, preventing cracking, moisture penetration, and joint failure caused by thermal movement and structural deflection.

System 6 installs high-performance silicone, polyurethane, hybrid SMP, and traffic-grade sealants depending on the application. Each product is selected based on movement capability, joint width, substrate compatibility, exposure conditions, and manufacturer specifications to ensure long-term durability.

Common signs include cracking, splitting, shrinking, hardening, loss of adhesion, gaps, missing sealant, discoloration, water leaks, and visible deterioration around windows, expansion joints, or concrete slabs. Replacing failed sealants early helps prevent moisture damage, mold growth, and costly repairs.

Failed sealants allow water, air, and moisture to penetrate the building envelope. Over time, this can lead to insulation damage, mold growth, freeze-thaw deterioration, corrosion of embedded metals, interior water leaks, and costly repairs to surrounding building materials. Water intrusion can also damage EIFS, masonry, concrete, window assemblies, and interior finishes, significantly increasing repair costs. Small cracks and gaps often become much larger problems if left untreated, making early sealant replacement one of the most cost-effective forms of preventative building maintenance.

Sealant restoration involves carefully removing failed caulking, inspecting the joint condition, replacing backer rod where necessary, preparing substrates, and installing new high-performance sealants that meet manufacturer specifications. Proper joint preparation is essential for achieving long-lasting adhesion and weather resistance.

Traffic-grade sealants are designed for horizontal expansion joints exposed to vehicle and pedestrian traffic. They are commonly installed in parking garages, parking lots, sidewalks, loading docks, drive lanes, plazas, industrial facilities, and landscape hardscapes where durability and movement accommodation are critical.

Yes. Commercial-grade sealants are commonly installed in retaining walls, concrete walkways, pool decks, patios, curbs, planters, stairs, decorative concrete, and other landscape construction projects. Flexible landscape joints help accommodate seasonal movement while preventing water infiltration that can contribute to cracking and freeze-thaw damage.

Backer rod is a compressible foam material installed beneath sealant to control joint depth, improve flexibility, reduce unnecessary sealant usage, and promote proper two-sided adhesion. Correct backer rod installation allows sealants to stretch and perform as designed throughout the life of the joint.

Silicone sealants provide exceptional UV resistance, flexibility, and long-term weather durability, making them ideal for many exterior building envelope applications. Polyurethane sealants are highly durable, paintable, and well suited for concrete, masonry, and many construction joints where abrasion resistance is important. The appropriate product depends on the specific application, substrate, and movement requirements.

In most situations, existing sealant should be completely removed before installing new material. Applying fresh sealant over deteriorated, contaminated, or incompatible products often leads to poor adhesion, premature failure, and a significantly shorter service life. Proper surface preparation is essential for a successful installation.

High-quality sealant systems help improve energy efficiency, reduce uncontrolled air leakage, prevent water intrusion, protect insulation, minimize maintenance costs, and extend the service life of exterior wall assemblies. Properly maintained joints are an essential part of a durable, weather-resistant building envelope.

System 6 installs premium commercial sealant systems using manufacturer-approved materials, proper joint preparation techniques, and industry best practices. Every project is evaluated individually to determine the appropriate sealant, movement capability, joint configuration, and substrate compatibility, ensuring reliable long-term performance for perimeter joints, expansion joints, traffic-rated systems, landscape applications, and sealant restoration projects.
