What is Crown Molding?
Crown molding is a type of decorative trim installed at the junction of walls and ceilings. It adds visual appeal and can range from simple, clean lines to intricate designs with multiple layers. Crown molding serves both aesthetic and functional purposes:
- Covers wall-to-ceiling transitions
- Hides minor drywall imperfections
- Adds value and sophistication to interiors
Common materials include MDF (medium-density fiberboard), wood, PVC, and polyurethane. It’s used in dining rooms, living rooms, bedrooms, hallways, and kitchens to enhance the space.
Why Use a Crown Molding Installation Cost Calculator?
Installing crown molding involves several cost variables, such as material type, room dimensions, labor rates, and the complexity of corners or ceiling height. A Crown Molding Installation Cost Calculator can help you:
- Estimate cost based on linear feet
- Choose between different molding materials
- Budget for labor or plan for DIY installation
- Avoid hidden costs like caulking, painting, or corner blocks
This tool is especially useful if you’re upgrading multiple rooms or comparing trim styles.
Average Cost to Install Crown Molding
On average, crown molding installation costs range from $5 to $15 per linear foot depending on material, finish, and labor. A 12×12 room (with ~48 linear feet) could cost:
- $250 to $700 for basic materials and installation
- $1,000+ for premium materials or complex designs
Here’s a general breakdown:
- Material: $1 to $8 per linear foot
- Labor: $2 to $7 per linear foot
- Painting/Finishing: $1 to $3 per linear foot (optional)
Crown Molding Cost Formula
Use this simple formula to estimate your total cost:
$$\text{Total Cost} = \text{Total Linear Feet} \times \text{Price per Linear Foot}$$
Example:
If you’re installing 100 linear feet of molding at $10 per foot:
100 × 10 = $1,000
This estimate includes materials and basic labor. Add painting or advanced finishes separately.
Factors That Affect Crown Molding Costs
1. Room Size and Shape
Total linear footage is calculated by measuring the perimeter of the ceiling. A simple square room has fewer cuts and corners, reducing labor time. Larger or oddly shaped rooms require more effort and increase total cost.
2. Material Type
| Material | Cost per Linear Foot | Pros | Cons |
|---|---|---|---|
| MDF | $1 – $3 | Inexpensive, easy to paint | Not moisture-resistant |
| Wood | $2 – $6 | Natural, classic appearance | May warp or crack |
| Polyurethane | $2 – $4 | Lightweight, flexible | Can dent easily |
| PVC | $3 – $5 | Moisture-resistant, durable | Limited styles and textures |
| Plaster | $5 – $15 | High-end, intricate designs | Expensive, heavy, fragile |
3. Ceiling Height
Rooms with ceilings over 9 feet often require scaffolding or ladders, which increases labor cost. Higher ceilings also require wider or more elaborate molding styles to remain proportionate.
4. Corners and Angles
Rooms with multiple corners, vaulted ceilings, or irregular angles require more precise cutting and fitting. Labor rates rise with each extra mitered corner or joint.
5. Finish Work
Crown molding may require:
- Painting or staining
- Caulking gaps
- Nail hole filling and sanding
These steps add about $1–$3 per linear foot if done professionally.
6. DIY vs. Professional Installation
DIY installation saves on labor but requires tools like:
- Miter saw
- Nail gun
- Ladder or scaffold
- Caulking and painting tools
Professional installers bring the tools and expertise but charge for labor.
Sample Installation Scenarios
Example 1: Single Room with MDF Crown Molding
- Room size: 12×12 (48 linear ft)
- MDF molding: $2/ft
- Labor: $5/ft
- Painting: $2/ft
- Total Cost = 48 × (2 + 5 + 2) = $432
Example 2: Entire First Floor with Wood Molding
- Total length: 250 linear ft
- Wood molding: $4/ft
- Labor: $6/ft
- Total Cost = 250 × (4 + 6) = $2,500
Example 3: DIY with Polyurethane Molding
- Length: 80 linear ft
- Material only: $3/ft
- Tools and supplies: $100 (one-time)
- Material Cost = 80 × 3 = $240
- Total = $340 (including tools)
Crown Molding for Different Spaces
| Room Type | Recommended Style | Cost per Room (avg) |
|---|---|---|
| Living Room | Layered or ornate | $400 – $1,200 |
| Bedroom | Smooth or traditional | $300 – $700 |
| Dining Room | Decorative with trim backing | $500 – $1,000 |
| Kitchen | Moisture-resistant material | $350 – $800 |
| Bathroom | PVC or polyurethane only | $250 – $600 |
When Should You Use the Cost Calculator?
Use the calculator when:
- Planning a renovation or trim upgrade
- Comparing materials and trim styles
- Creating a room-by-room cost estimate
- Deciding between DIY or hiring a pro
- Determining how much molding to buy
It’s especially helpful before hiring contractors or shopping for trim at a home improvement store.
How to Measure Crown Molding
To measure accurately:
- Measure each wall in the room
- Add all lengths together for total linear footage
- Add 10% extra for waste and corner cuts
- Round up to the nearest full foot for purchasing
Example:
A room with four 12-foot walls = 48 linear feet
Add 10% = 48 × 1.1 = 52.8 ft
Round up → 53 linear feet
Tips to Reduce Crown Molding Installation Costs
- Choose MDF or polyurethane for cost-effective options
- Install in fewer rooms or use accent walls
- Opt for simple profiles instead of ornate styles
- Do the painting yourself to cut labor fees
- Bundle with other trim work (baseboards, wainscoting) for contractor discounts
- Use corner blocks to reduce miter cuts and simplify DIY
