Joint Sealant & Caulking

The First Line of Defense for Your Building Envelope

Properly installed and maintained joint sealants are one of the most critical components of a high-performing building. They prevent water, air, and pest intrusion at the seams where different materials meet. When these sealants fail, they create a direct path for costly damage.

CRG provides professional joint sealant and caulking services for new construction and restoration projects. We use high-performance materials to create durable, flexible, and weathertight seals that protect your property and improve energy efficiency.

Why Professional Sealant Application is Critical

Superior Weatherproofing

High-quality sealants prevent wind-driven rain and moisture from penetrating the building envelope, which is the leading cause of structural damage and mold.

Energy Efficiency

By sealing gaps and cracks, our services eliminate air leaks, reducing the load on your HVAC system and lowering your building’s overall energy costs.

Accommodating Movement

Buildings naturally expand and contract. We use flexible sealants that can accommodate this movement without cracking or losing adhesion, ensuring long-term performance.

Our Sealant Installation Process

01

Removal of Old Sealant

We begin by completely removing all old, failed sealant and any backing materials from the joint to ensure a clean substrate for proper adhesion.

02

Joint Preparation & Priming

The joint surfaces are mechanically abraded or solvent-cleaned. If required, a primer is applied to the substrate to enhance the new sealant’s bond.

03

Backer Rod Installation

A new, properly sized backer rod is installed in the joint. This critical step ensures the sealant has the correct depth and a two-sided bond for maximum flexibility.

04

Expert Sealant Application

The specified sealant is carefully installed, then tooled to create a smooth, concave bead that ensures a weathertight seal and a clean, professional appearance.
