Crown Moulding

Crown moulding is a classic choice that frames the junction between walls and ceilings, adding a refined, polished look to any room. It can make ceilings appear taller, creating a sense of grandeur in otherwise simple spaces. Whether your home leans toward traditional or transitional, crown moulding blends beautifully with its surroundings.

Modern Baseboards

Updated baseboards offer a sleek and functional look, ideal for modern spaces. These trim pieces hide transitions between floors and walls, creating clean lines for a cohesive design. Depending on your taste, you can opt for minimalist designs or intricate profiles that add subtle flair. They’re an inexpensive yet impactful upgrade to any room.

Picture Frame Moulding

Picture frame moulding is a playful way to enhance walls with panel-like designs. By creating symmetrical grid patterns or highlighting a specific focal wall, you can add visual interest and dimension to your walls. You might even try using bold paint or wallpaper within each frame for a standout effect.

Beadboard

Beadboard is a classic wall feature with narrow vertical planks and a small ridge or "bead" between each board. It adds warmth and charm, often creating a cottage-style or traditional look. Versatile and durable, beadboard can cover full walls or just below a chair rail. It's a great choice for kitchens, bathrooms, and mudrooms, offering easy maintenance and timeless appeal.

Wainscoting

Wainscoting is a decorative wall feature that adds wooden panels or mouldings to the lower portion of walls, usually 3 to 5 feet high. It brings texture, depth, and timeless charm to spaces like living rooms, dining areas, and hallways. Beyond its style, wainscoting protects walls from scuffs and damage. With styles like shaker panels and vertical boards, it’s a versatile way to boost both design and durability in your home.

Chair Rails

Chair rails divide a wall horizontally and are great for experimenting with two distinct wall treatments above and below the rail. Whether you pair a painted upper section with wallpaper below or two complementary paint colours, chair rails allow you to define a room with elegance.

The Many Benefits of Decorative Mouldings

Elevating Interior Design

Mouldings play a vital role in enhancing the architectural character of a space. They provide the perfect finishing element to create a polished and cohesive look. The flexibility of mouldings allows you to adapt them to any style—from classic to contemporary—to reflect your unique personality.

Defining Spaces

In open-concept layouts, mouldings play a key role in subtly dividing areas, creating a sense of structure and organization without the need for walls. By adding visual boundaries, mouldings can help differentiate spaces, all while maintaining an open and cohesive feel.

Adding Value to Your Home

When it comes to home improvements that pay off, decorative mouldings are an excellent choice. They have a timeless, high-end appeal that captures the attention of potential buyers. Even small updates, like installing crown mouldings or upgrading baseboards, can significantly boost your home’s perceived value. Plus, they leave a lasting impression, setting your property apart in a competitive market.

Functional Advantages

Decorative mouldings are not just eye-catching; they serve practical purposes too. Chair rails protect your walls from furniture scuffs and scratches, while baseboards effectively hide gaps between walls and flooring. Mouldings can also cover imperfections like uneven surfaces or cracks, offering a clean and polished appearance. Some mouldings, like window and door casings, even help seal gaps, improving insulation and energy efficiency.

Enhancing Acoustics & Lighting

The beauty of mouldings extends beyond visual appeal. Ceiling mouldings and crown designs can soften hard edges, improving a room’s acoustics by reducing echoes. Additionally, mouldings can be paired with lighting solutions like LED strips to create stunning effects, such as a soft glow around ceilings or walls, enhancing room ambiance.
