Good deck stairs and railings are the parts of a deck people grab and trust without thinking, so they get built to code and checked by hand.

Rail Styles
Wood rails match a wood deck and cost the least. Composite rails pair with composite boards and skip the sealing. Metal rails with thin balusters or cable keep the view open, which is nice on a raised deck that looks out over trees.
Steps That Feel Right
A stair where one step is taller than the rest trips people. We lay out the stairs so every step is the same, add a landing where a long run needs one, and give the bottom step a firm base so it does not sink.
Posts That Do Not Wobble
Most loose railings come from posts that were only nailed to the rim. We fasten rail posts with through bolts and blocking so they stay put. Cedar Park adopted the 2021 International Residential Code with local amendments. We build rails and stairs to that code.
Questions
Can you replace just the railing?
Yes, if the deck frame is sound. We check the rim and posts first, since a new rail is only as strong as what it bolts to.
What rail is best for a view?
Cable or thin metal balusters block the least. They cost more than wood.
Can you add stairs to an old deck?
Usually, yes. The deck has to be sound where the stairs attach.
