Deck railings, stairs and landings in Rochester
Railings that don’t wobble and stairs that don’t rock, whether you are replacing old ones or building new.
Railings, or guards, keep people from falling off a raised deck, and stairs and landings connect it to the yard. If a Rochester-area deck has a loose rail, a rocking stair or a railing that won't pass a home inspection, we connect you with an independent contractor who rebuilds or upgrades them.
What do Rochester's rules say?
The City of Rochester's deck handout says guards are required at least 36 inches high on decks more than 30 inches above grade, and openings must be small enough that a 4-inch sphere can't pass through. Olmsted County's deck supplement adds that guards must withstand 200 pounds of applied force. Stairs follow the Minnesota Residential Code for rise, run and handrails; your contractor will draw them on the permit plans.
Railing materials
- Treated wood or cedar. Simple and affordable. Needs finish, and posts need solid blocking to stay tight.
- Aluminum. Thin balusters, powder-coated colors, no painting.
- Composite or vinyl. Pairs with composite boards; posts are thicker.
- Cable or glass. Keeps the view open toward the trees or a pond, but needs very stiff posts.
Why railings loosen
Every push on a top rail pries at the post's base. A post held by two nails or small lag screws loosens a little each year as the wood swells in wet weather and shrinks when it dries or freezes. Modern guard posts are typically through-bolted and tied into blocking or joists with hardware so they hold that 200-pound load year after year.
Stairs and landings in a snowy climate
With more than 50 inches of snow in a typical Rochester winter, deck stairs see shovels, ice melt and wet boots for months. Stringers should land on a concrete pad or a frost-protected footing rather than bare soil. A mid-height landing breaks up a tall run on a walkout lot, and a handrail on both sides helps on icy days.
What changes the cost?
- Length of railing and the system you choose
- Post reinforcement or new rim joists
- Number of stairs, landings and turns
- Gates, lighting and post caps
