Protection Starts Behind the Panels

Our Process for Moisture-Resistant Drywall Installation

We follow best practices for clean, durable and moisture-conscious wall systems in demanding commercial environments.

We begin by evaluating the humidity levels, airflow and moisture exposure in your space. Based on conditions and occupancy type, we select the appropriate moisture-resistant board — including mold-resistant or fiberglass-reinforced options. We also assess surrounding systems like insulation, plumbing and ventilation. This ensures the right solution is applied for long-term performance.
Our team checks that framing is level, corrosion-resistant and spaced for optimal board support. We verify proper backing, furring, or vapor barriers are in place if needed. Substrates are cleaned and dried prior to installation to prevent mold risk. Every surface is prepared to manufacturer specs for moisture control.
We cut and install panels using moisture-resistant fasteners and appropriate spacing. Boards are installed with staggered joints, tight seams and consistent screw depths to prevent surface breaches. Special attention is paid to penetrations, fixture cutouts and ceiling transitions. We leave gaps where required for movement or sealant application.
We apply mold-resistant tape and setting-type compounds formulated for wet-area use. All joints are sealed and feathered for a clean finish and we avoid paper-faced materials in high-risk zones. For exposed areas, we may add tile backer or fiberglass mesh for added protection. This step ensures the system resists water intrusion where it matters most.
After installation, we inspect all seams, corners and transitions to confirm moisture resistance and integrity. We clean the work area, mark out walls for the next trade and hand off a surface ready for tile, FRP, or paint. Our team ensures no shortcuts are taken — just reliable walls that stand up to moisture. Your space is left code-compliant, sealed and protected.

Walls That Withstand the Wet

When Moisture-Resistant Drywall Is the Right Choice

Moisture-resistant drywall is essential in commercial interiors where humidity, splashes or steam are part of daily operations. It’s commonly used in kitchens, locker rooms, janitor closets, restrooms and washdown areas – any space where standard drywall would deteriorate over time. These boards resist mold growth, maintain structural integrity and help protect the walls behind tile, FRP or paint finishes. For long-term durability in damp environments, this upgrade is not optional – it’s essential.

You’ll need moisture-resistant drywall during new builds or renovations involving wet-area zones or mechanical spaces. It’s also a smart replacement in spaces where previous drywall showed signs of moisture damage or microbial growth. Building managers often choose this system proactively to reduce maintenance costs, minimize health risks and extend the life of interior surfaces. If your Toronto facility faces constant exposure to moisture – this is the wall system that works.
