Millwork, Moulding, and Stair Parts

Millwork is an interior construction material traditionally made in a mill with milling machinery, although modern millwork uses many other manufacturing techniques. Millwork includes doors, windows, trim, mouldings, stairs, cabinets, and custom architectural woodwork that has decorative and functional roles in residential and commercial construction projects. Millwork is made of materials that include wood, engineered wood, composites, and metals. 

Mouldings, also spelled moldings, are strips of decorative material used to finish interior walls, ceilings, and door and window frames. On walls and ceilings, mouldings hide seams and transitions between materials, provide subtle lighting accents, and add visual interest. Around doors and windows, mouldings known as door and window casings provide an attractive border and cover gaps between framing and walls.

A stair system is the complete set of components that make up a staircase. It includes the stair steps and risers, as well as additional parts like stringers, newel posts, balusters, handrails, and landings. At LS Building Supplies, we stock a comprehensive selection of stair parts and stair systems in many designs and materials.

Choosing the right paint for interior doors depends on the material of the door and the finish you desire. For wood, stile and rail, or wood composite doors, a high-quality acrylic latex paint offers durability and a smooth finish. For doors with glass panels or those located in high-traffic areas, consider using semi-gloss or gloss paint for added durability and easy cleaning. Always start with a primer suited to your door's material to ensure the best adhesion and finish. Our selection includes various paint options from leading manufacturers, ensuring you find the perfect match for your interior design needs while maintaining the door's aesthetic and practical functions.

Replacing door trim moulding involves a few key steps: removing the old trim carefully to avoid damage to the wall or door frame, measuring the new trim to fit the door, cutting the trim accurately, and installing it securely with finishing nails or adhesive. Before installation, ensure the trim is primed (if necessary) and painted to match your interior. For a seamless finish, use wood filler to cover nail holes, then sand lightly and apply a final coat of paint. Our extensive range of moulding options, including pine, MDF composite, and flex trim, offers the versatility to achieve any look, from sleek and modern to traditional, ensuring a professional and cohesive interior design.
