Residential & Commercial Exterior Moulding
Exterior moulding is the decorative trim applied around windows, doors, rooflines, and building facades to enhance architectural detail and add visual depth. Beyond aesthetics, properly installed mouldings serve a practical purpose — they help direct water away from your walls, protect joints and transitions from weather penetration, and frame the key features of your building’s exterior. Whether crafted from EPS foam with a cement coating, PVC, or composite materials, exterior mouldings are lightweight, durable, and designed to withstand Ontario’s harsh climate without cracking, rotting, or warping.

Common Exterior Moulding Problems
Exterior mouldings take a beating from Ontario’s weather — freeze-thaw cycles, wind-driven rain, and UV exposure can all cause wear over time. Catching issues early keeps your trim looking sharp and prevents water from getting behind your cladding.
Moulding Pricing & Estimates
Exterior moulding costs vary depending on the scope and detail of your project. Here’s what you need to know to plan with confidence:
The price of exterior moulding depends on the material type, profile complexity, number of pieces, and building height. Custom shapes, large cornices, and multi-storey access will also affect the final cost.
Our experienced team provides itemized estimates covering materials and labour — no hidden fees, just honest pricing. You'll know what to expect before any work begins.
Inspecting your mouldings for cracks, loose sections, and sealant failure every couple of years prevents water from getting behind the trim and damaging your walls. A small repair now saves you from a full replacement later.
Whether it's a new installation or a repair to damaged trim, our team responds quickly and gets the job done right — minimizing disruption and keeping your exterior looking its best.

Why Choose Exterior Moulding for Your Property
Instant Curb Appeal
Nothing transforms a flat, plain facade faster than well-placed exterior mouldings. Window surrounds, door casings, cornices, and band courses add depth, shadow lines, and architectural character that make your home stand out on the street. It’s one of the most cost-effective ways to dramatically upgrade your building’s appearance.
Weather Protection at Key Joints
Mouldings aren’t just decorative — they serve a functional role by covering and protecting the most vulnerable transitions on your exterior. Properly installed trim directs water away from window and door openings, prevents moisture from penetrating behind your cladding, and reduces the risk of rot and mould in your wall assembly.
Lightweight & Built for Ontario's Climate
Modern exterior mouldings made from EPS foam with a cement-based coating are incredibly lightweight, which means they won’t stress your walls or framing. They’re also designed to handle Ontario’s temperature extremes — expanding and contracting with the seasons without cracking or pulling away from the building. Unlike wood trim, they won’t rot, warp, or attract insects.
Custom Profiles to Match Any Style
Whether your home is modern, traditional, or somewhere in between, exterior mouldings can be custom-shaped to match your vision. From simple flat bands to ornate cornices and keystones, the design possibilities are virtually unlimited. Our team works with you to select profiles that complement your existing exterior and deliver the exact look you want.
