Casing Moulding

Casing mouldings are the perfect finishing touch that frames your windows and doors - both hiding gaps and adding a polished, architectural flair. At Woodwork Manufacturing & Supply, we feature a versatile selection of mouldings from trusted vendors like Andersen, Jeld-Wen, and Windsor Windows & Doors. Whether you’re updating a classic home or adding style to a modern build, our options offer both function and elegance.

What is Casing Moulding?

These mouldings refer to the strips of trim installed around the edges of windows and doors. They serve a dual purpose: covering gaps between surfaces like drywall and frames, and delivering a decorative, finished appearance.

These mouldings are often the most visible trim in a room and come in a range of styles from the clean lines of craftsman and ranch to more ornate colonial or Victorian profiles.

Frequently Asked Questions

What’s the difference between casing and general trim?

Trim is an umbrella term that includes all decorative mouldings - like baseboards, crown, and chair rails. Casing specifically refers to the moulding around windows and doors.

What materials are these mouldings available in?

Moulding options include solid wood (for traditional warmth), primed MDF (great for painting), and composites (which resist moisture and are highly durable).

Can these mouldings be used on both doors and windows?

Yes! They are conveniently designed to frame both window and door openings, and you can use the same style across the entire home for a seamless aesthetic.

Are these mouldings just decorative?

No - the mouldings serve a practical purpose too, covering gaps between the wall and frame and helping insulate your home by sealing those spaces effectively.

Types of Moulding Profiles

Choose Your Perfect Moulding Profiles

Casing

Used to frame doors and windows, casing moulding provides a clean transition between the wall surface and openings while adding architectural definition.

Base

Installed where the wall meets the floor, base moulding protects walls from impact and creates a finished, cohesive look throughout the room.

Crown

A decorative element installed where walls meet the ceiling, crown moulding adds depth, dimension, and elegance to any interior.

Jambs

Door jambs form the vertical and horizontal framework that supports a door within its opening, ensuring a precise fit and smooth operation.

Stop

Door stops are fitted within the jamb to control the door’s closing position, preventing damage and creating a snug, finished seal.

Base Shoe

A small, rounded trim piece installed at the bottom of base moulding to conceal gaps between the floor and wall, often used with hardwood or tile flooring.

Cove

Curved and smooth in profile, cove moulding is perfect for soft transitions between surfaces or as a decorative detail in cabinetry and ceilings.

Fire Casing

Specially designed to meet fire-resistance requirements, fire-rated casing provides both safety and a clean, consistent appearance around rated door openings.

Panel

Panel moulding adds depth and texture to walls or ceilings, ideal for wainscoting, feature walls, or creating custom architectural detailing.
