Door sill trim insert

The plastic trim under the door of a car is called a door sill trim insert. It is also known as a door protector or side moulding.

The door sill trim insert is a plastic piece that is located on the floor of the car, right inside the door. It is the part of the car that you step on when entering or exiting the vehicle. Over time, this piece may become loose and need to be re-secured.

The door sill trim insert can be held in place by clips or retainer pegs. In some cases, the retainers may break or become damaged, requiring replacement. When searching for replacement parts, it is important to know the specific make and model of the car, as well as the type of retainer used.

Some car owners choose to customise their door sill trim inserts, for example, by adding lighting or engraving the car's make and model. This can enhance the appearance of the car's interior and showcase the owner's personal style.

Overall, the door sill trim insert serves a functional purpose by protecting the car's interior from wear and tear, while also providing an opportunity for customisation and self-expression.

Side mouldings

In addition to side mouldings, there are also plastic trim pieces found on the interior of cars, such as the floor trim or the door sill trim insert. These trim pieces can become loose and may need to be secured with retainer pegs or clips. When searching for replacement parts, it is important to know the specific name and part number for the trim piece in question.

Overall, side mouldings and plastic trim pieces serve both functional and aesthetic purposes in cars, protecting the vehicle from damage and adding decorative touches. Proper maintenance and replacement of these parts can help keep your car in good condition.

Running trim

When it comes to trimming doorways, there are two main types of door trim: mitered trim and butted trim. Mitered trim features 45-degree angled cuts at the corners, resulting in a seamless look. This style is commonly chosen for modern settings or homes with low ceilings. However, it tends to be more challenging as a DIY project. Butted trim, on the other hand, has square-cut ends that meet at 90-degree angles, offering more customization options with larger head casings. This type is generally easier for DIY enthusiasts as it does not involve joining angles.

Installing door trim is a simple DIY project that can enhance the aesthetics of your home. Before starting, it is crucial to make accurate measurements and calculations to ensure a proper fit. The process involves using a miter saw to cut the moulding pieces at the desired angles and lengths. It is recommended to cut the moulding on one end longer than the doorway's width and then measure and mark the opposite end for cutting. The trim should be installed slightly away from the jamb edges to prevent unintentional gaps that may form over time.

To secure the trim, nails, glue, or a combination of both can be used. Finish nails, typically in 4d and 6d sizes, are employed to attach the trim firmly. After nailing, a nail set can be used to drive the nail heads below the surface of the trim for a smoother finish. Gaps and nail holes can be filled with wood filler or paintable putty, depending on whether the trim is stain-grade or paint-grade. Finally, caulk should be applied to seal the edges and create a smooth transition between the trim and the wall.

Standing trim

A front door and trim do not need to be the same colour. In fact, it is common to use contrasting colours to emphasise the casing. However, a matching door and trim can also make a unique style statement.

Interior door trim is also common in the USA and Australia. In Australia, high-volume homes often come with architraves (trim) as standard. In the USA, trim is often used to cover imperfections in construction.
