How Much Does Interior Trim Installation Cost?

Installing interior trim can enhance and redefine the character of a single room or your entire home. Wood is the most popular option for trim moldings and your choice of trim styles and wood species, grade, and finish will help define the scope and cost of your installation project. Interior trim is typically installed by a finish carpenter who can customize the look of your home by combining manufactured trim elements or creating custom milled moldings for your application.

Average Prices

Installing Trim in Homes and Businesses

Trim styles and finishes add an important design element to any building, but the characteristics and accessibility of different locations may affect the price of installation. Single-family homes are often larger than apartments, and the availability of work space for your carpenter to stage materials and tools often simplifies the job. The national average price for installing trim in a home is $378, compared to $376 for apartments and $380 for business buildings. Logistical issues in apartment and commercial buildings may add expense for additional time or manpower needed to accommodate special scheduling, inconvenient work areas, or for navigating elevators and stairways with tools and materials.


New and Replacement Trim Installation

New installations of trim are typically done during construction or renovation, when the work site is free of furnishings and is easily accessible. The average price for a new trim installation is $378, while replacing existing trim averages $370. A replacement project requires the removal and disposal of old trim and may require your carpenter to work around obstacles in your home.


Project Size

The size and scale of your trim project will help determine the time and materials that are needed for the job. Average prices for installing trim in the U.S. range from $318 for a 100-200 square foot area, $387 for 200-300 square feet, $543 for 300-400 square feet and $617 for a 400-500 square foot space.


Crown Molding Installation Cost

Crown molding adds a dramatic trim feature to any room and is available in countless profiles to suit your design scheme. Installing crown molding may require your carpenter to use ladders and extra manpower for fitting the trim pieces overhead. Prices for installing crown molding range from $238 to $836 nationally, and often depend on the size of the job and the intricacy of the molding design and application.


Installing Colonial Case Molding

Case moldings are used to trim around doors, windows and openings and come in variety of profiles and designs. Colonial is a popular style that is often installed with mitered corners, and generally costs between $196 to $687 to install. Variables in pricing the installation of case moldings are generally related to the number and size of openings that require trim.


Wainscot Trim Molding Installation

Adding trim moldings to wainscoting gives a finished look to a popular wall treatment. Wainscot cap moldings are designed to fit neatly at the top of wall panels and come in styles that vary from a detailed chair rail to a narrow shelf. Prices range from $245 to $859 for installing wainscot trim, and vary with the type of trim to install and the condition of the existing wainscoting.


Shadow Box Trim

Shadow box trim provides the look of dimensional panels with the application of trim pieces to a wall surface. The intricacy of the design pattern and style of trim used contributes to the cost of this project, which is priced between $205 and $719 across the U.S.


Installing Base Cap

Installing base cap moldings to baseboard adds a decorative element to an often overlooked room detail. Base cap is often a slender trim piece, but can have a variety of profiles. National prices for installing base cap range from $210 to $736 and are affected by the type of trim used and the complexity of matching the new trim to existing baseboard.


Chair Rail Installation

Adding chair rail trim to walls provides a substantial design element to a room, but also serves to protect wall surfaces from being damaged by furniture. Chair rail styles vary from a simple, profiled molding to a narrow, flat shelf or an elaborate, multi-layered trim element. The complexity of design and integration with existing trim affect project prices between $137 and $480 nationwide.


Planning for Interior Trim Installations

Adding, replacing, or upgrading trim elements can change or enrich the aesthetic of your home. A wide array of architectural styles influences standard trim choices, and custom millwork makes design possibilities endless. Your designer or carpenter can help you determine what types and styles of trim will enhance your home and reflect your taste and lifestyle.
