Deck Railing Replacement Cost by Material
Deck railings typically cost $35–$210 per linear foot installed, depending on the material and style. Stairs, posts and code requirements affect the total.
Material options
| Material | Relative cost | Notes |
|---|---|---|
| Pressure-treated wood | Lowest | Needs sealing or paint; can split |
| Composite or vinyl | Middle | Low maintenance; often sold as kits |
| Aluminum | Middle to high | Low maintenance; slim profile |
| Cable | High | Open views; needs strong posts to hold tension |
| Glass panels | Highest | Unobstructed views; needs cleaning |
Overall range of $35–$210 per linear foot from our deck and patio cost guide. Prices vary widely by product.
Example budgets
| Railing length | At $35–$210 per linear ft. |
|---|---|
| 30 ft. | $1,050–$6,300 |
| 50 ft. | $1,750–$10,500 |
| 80 ft. | $2,800–$16,800 |
Stair railings are usually priced separately and cost more per foot because of the angles.
Code basics
Most U.S. building codes are based on the International Residential Code. Typical requirements include:
- Guards on decks more than 30 inches above the ground.
- Guards at least 36 inches high on most residential decks (some areas require 42).
- Openings small enough that a 4-inch sphere cannot pass through.
- Handrails on stairs with four or more risers.
Requirements vary by city and county, and many require a permit for railing replacement. Check with your local building department.
Check the posts
Railings are only as strong as the posts and how they attach to the deck framing. If posts are loose or rotted, they need replacing too. See deck resurfacing vs. replacement.
