Aluminum trim is a critical component for your home and roof to help protect it from the elements. Aluminum trim can not only prevent water and dampness from seeping into your home, but it is also effective at prohibiting the entrance of birds and pests which may be looking to make their nest in your attic. The trim is typically installed beneath gutters to prevent the water from coming in underneath the rafters. Aluminum is a popular option for this trim as it is known to be more durable and last longer than other options. It can also be used in the home as an accent to modernize the look of a space.

Aluminum trim is priced by the linear foot, and the cost installed will include labor, supplies, and additional materials. The cost to install trim on the exterior or interior of a home depends on the amount of space being trimmed, whether the installation requires the use of ladders or other equipment, and how many corners or areas need special piecing. On average, aluminum trim installation costs between $2,800 and $5,000, with the average homeowner paying $3,200 for installing interior aluminum trim, including door and window casings and baseboards in a 1,500 square foot home. Projects run as low as $500 for exterior aluminum trim around a garage door to as high as $11,500 when it involves interior and exterior trim for a 2,000 square foot house.
