What is the trim around a garage door called?

The trim around a garage door that covers the gap between the door frame and the wall is typically called garage door trim or garage door jamb trim. This trim serves both decorative and functional purposes.

What is Garage Door Trim?

Garage door trim refers to the boards that are installed around the edges of the garage door frame. It covers the seam between the door jamb (the vertical parts of the frame) and the wall surrounding the garage door opening.

This trim molding is typically made from wood, metal, vinyl, or other materials. It comes in various widths, thicknesses, and styles to match the look and design of the garage door and home’s exterior.

Purposes of Garage Door Trim

There are a few important reasons garage door trim is installed:

• Covers rough edges and gaps – The trim creates a smooth transition between the door jamb and wall, covering any uneven gaps or rough openings.
• Finishes garage door installation – It provides a complete, finished look around the edges of the new garage door.
• Enhances curb appeal – Decorative trim can upgrade the look of the garage door and enhance curb appeal.
• Weatherproofing – Seals gaps against outdoor elements like rain, wind, and drafts.
• Insulation – Foam backer rod is often placed under the trim to provide insulation around the door.

Wood Trim

– Primed, painted, or stained
– Traditional look, affordable option

PVC/Vinyl Trim

– PVC and vinyl polymers

– Low-maintenance, resists moisture
– Molded styles mimic wood trim look

Metal Trim

– Aluminum, galvanized steel
– Very durable, low maintenance

– Often has color-coated finishes

Fiber Cement Trim

– Fiber cement board with resin
– Durable, resists rotting and insects
– Can be painted or have faux wood grain finish

Miratec or Composite Trim

– Proprietary synthetic materials

– Extremely durable, won’t warp

Garage Door Jamb Dimensions

The dimensions of the garage door jamb establish the appropriate width for selecting trim. Measure across the width of the side jambs and height of the header jamb to determine the lengths needed.

Some standard jamb widths:

• 16-foot wide door – jambs approx. 17 inches wide
• 18-foot wide door – jambs approx. 19 inches wide
• 20-24 foot wide door – jambs approx. 29 inches wide

The header jamb above the opening is typically 4-5 inches tall. In general, go with trim boards that are slightly wider than the jambs to ensure full coverage.

How to Install Garage Door Trim

Installing trim around a new or existing garage door opening involves the following basic steps:

1. Measure the door jambs and wall opening.
2. Cut trim boards to fit the dimensions.
3. Pre-drill trim boards to avoid splitting.
4. Apply adhesive and attach trim around jamb edges.
5. Nail the trim in place with galvanized finish nails.
6. Caulk along the edges for weatherproofing.
7. Prime and paint the trim to match the door or home exterior.

Watch for bumps, gaps, or misalignment and make sure the boards are secure. Using a level helps keep the trim straight and properly positioned. Take care not to drive nails too deep into the jambs underneath.

Tips for Installing Garage Door Trim

• Use treated lumber for humidity resistance.
• Choose foam backer rod and caulk for better insulation.
• Use corner joint trim pieces for a seamless look.
• Leave small gaps between boards for expansion and contraction.
• Work slowly for best results on curved header jambs.

Maintaining Garage Door Trim

Regular maintenance is important for keeping garage door trim looking its best. This involves:

• Inspecting trim for damage, warping, caulk failure, etc.
• Replacing or repairing trim as needed.
• Re-caulking gaps every 1-2 years.
• Repainting trim when the finish deteriorates.
• Washing with mild soap and water annually.

Proper garage door trim installation and maintenance ensures it lasts for many years while providing decorative appeal and protection from the elements.
