Deck Railing Installation and Replacement
A wobbly or rotted railing is a safety problem, and an outdated one can make a whole deck look tired. We replace railings on existing decks and build new ones that meet today’s height and spacing rules.

How we approach deck railings
Most railing failures start at the posts. Posts notched and nailed to the rim joist, or bolted without blocking behind them, loosen a little every year until the whole section moves. When we replace a railing we fix the post connections first, with blocking and structural fasteners, so the new rail stays tight.
Style is your call. Wood and composite railings match a traditional deck and cost the least. Black or white aluminum is our most popular choice: slim, strong, and never needs paint. Cable and glass keep the view open on decks facing water or mountains and cost more per foot.
Code requires guards on decks more than 30 inches above grade, typically 36 inches tall with openings small enough that a 4-inch ball cannot pass. Stair railings need a graspable handrail. We build to those rules and to your city’s requirements.
What the job includes
- Removal and haul-away of the old railing
- Post connections checked and reinforced with blocking and structural fasteners
- New railing in wood, composite, aluminum, cable or glass
- Matching stair railings and graspable handrails
- Optional post-cap and under-rail lighting
