Crown Molding Installation Cost Factors

Installing crown molding in St. Louis, MO, requires careful planning and the right materials to match your home's style. Local carpenters factor in the size of your space, the type of molding, and the complexity of the room when determining the final price for this project.

The total length of the room directly dictates the amount of material and time required for the project. Larger rooms demand more supplies, driving up the final price.

Cost to Install Crown Molding by Size

The width of the molding and the height of your ceilings play a major role in material expenses. Taller ceilings require wider molding profiles to look proportionate, which increases the price of the trim.

93–7.5$5–$30$4–$30
104–9$10–$35$6–$35
12+6–12+$10–$50$7–$50

Rooms with standard 8-foot ceilings use 2.5- to 6-inch molding, running $5 to $25 per linear foot. If your home features grand 12-foot ceilings, you need 6- to 12-inch molding, which costs $10 to $50 per linear foot.

Cost to Install Crown Molding by Material

The material you select impacts both the upfront supply price and the long-term durability of the trim. Some materials withstand the humid summers in St. Louis, MO, better than others.

MaterialLocal Cost to Install (Per Linear Foot)National Cost to Install (Per Linear Foot)
Solid wood$5–$30$3–$30
Polyurethane$5–$10$2–$10
Plaster$10–$20$6–$20
MDF$5–$10$1–$7
PVC$5–$5$1–$4
Foam$5–$5$1–$4
Metal$10–$30$10–$30

Polyurethane is a moisture-resistant option that costs $5 to $10 per linear foot. Plaster offers a high-end, traditional look but requires specialized skills, bringing the price to $10 to $20 per linear foot.

Solid Wood

Solid wood provides a classic, warm aesthetic that takes stain beautifully. The specific species of wood you choose determines the final material price.

Type of WoodExampleLocal Cost per Linear FootNational Cost per Linear Foot
Common softwood and young growthNew growth pine, maple, and aspen$5–$10$3–$10
Old-growth softwoodSeasoned, mature pine$10–$15$10–$12
Common hardwoodOak and mahogany$10–$15$10–$12
Exotic hardwoodBrazilian cherry, paduk, and ipe$15–$30$15–$30

Common softwoods like pine and aspen cost $5 to $10 per linear foot. Exotic hardwoods like Brazilian cherry or mahogany run $15 to $30 per linear foot due to their durability and rich grain patterns.

Polyurethane

Polyurethane molding resists rot and warping, making it an excellent choice for areas prone to moisture. It provides the look of wood without the susceptibility to humidity.

Expect to pay $5 to $10 per linear foot for polyurethane materials. This lightweight option installs quickly, keeping labor expenses on the lower end of the spectrum.

Plaster

Plaster molding delivers intricate, custom details ideal for historic homes. Because it is heavy and fragile, it requires a highly skilled professional to handle the installation.

Premade plaster molding costs $10 to $20 per linear foot. Repairing existing traditional plaster in an older home costs significantly more due to the specialized restoration techniques required.

MDF

Medium-density fiberboard (MDF) is a budget-friendly alternative to solid wood that takes paint exceptionally well. It is lightweight and straightforward to cut.

MDF crown molding runs $5 to $10 per linear foot. Keep MDF out of bathrooms or kitchens, as it absorbs moisture and swells in damp environments.

PVC

PVC molding is completely waterproof, making it the perfect solution for bathrooms or basements. It handles the extreme, unpredictable seasons in St. Louis, MO, without warping or degrading.

PVC molding costs a flat $5 per linear foot. It comes pre-finished in white and does not hold paint well, so it is best left in its original color.

Polystyrene Foam

Polystyrene foam is the lightest material available and cuts easily with basic hand tools. It works well for quick room updates where intricate detail is not a priority.

Foam molding costs $5 per linear foot. While it installs easily with adhesive, it dents easily and lacks the sharp, crisp edges found in wood or polyurethane.

Metal

Metal crown molding adds an industrial or modern touch to a room and stands up well to wear and tear. Aluminum, copper, and steel are the most common options.

Metal molding costs $10 to $30 per linear foot. Aluminum is particularly popular because it resists rust and remains lightweight during installation.

Additional Cost Factors of Installing Crown Molding

Beyond the length and material type, several other variables influence your final project price. Complex room layouts and custom finishes require more time and precision from your contractor.

Labor

Hiring a professional ensures precise cuts and seamless corners, preventing gaps and wall damage. Contractors factor in the time and difficulty of the job when setting their hourly or per-project rates. Standard rooms take two to three hours to complete, which directly impacts your final labor expenses.

Style or Custom Finish

Intricate molding profiles like Victorian or craftsman styles demand more precision than standard colonial designs. Custom-milled profiles designed to match historic trim increase both material and labor prices, as they require specialized fabrication and careful installation.

Installation Complexity

Rooms with multiple corners, alcoves, or uneven ceilings force the installer to make more complex cuts. Each additional cut takes time and increases the amount of scrap material generated. Complex layouts increase labor expenses significantly. To keep the project looking pristine, you also need to account for drywall repair costs if the walls require patching or smoothing before the molding goes up.

Door and Window Crown Molding

Adding matching crown molding above doors and windows creates a cohesive, high-end look throughout the room. This requires additional materials and precise miter cuts to fit the existing frames, adding to the overall project total. If you are updating the entire room, factor in baseboard installation costs to ensure the floor trim matches the new ceiling details.

Painting or Staining Crown Molding

Finishing the molding with paint or stain protects the material and ties it into your room's color palette. High-quality finishes ensure the trim looks fresh for years to come, but require additional labor and supplies. If you want to refresh the entire space, scheduling interior painting at the same time ensures a flawless transition between the walls and the new trim.
