Get matched with top wood stairs and railings installers and replacers in your area

Yes—if the railing is still structurally sound, you can leave it in place. Start by tightening any loose fasteners and repairing minor damage, then sand, paint, or refinish the surface for a fresh look. Updating instead of replacing keeps costs down, shortens the project timeline, and still lets you meet local building-code standards. Just be sure the handrail feels solid before you commit to cosmetic upgrades.

Reusing spindles is a smart, budget-friendly move as long as they’re in good shape. Tell your contractor up front so they can remove and store the pieces safely. Once the new railing is in, sand and repaint or stain the spindles to match. Keeping the originals cuts material costs, reduces waste, and preserves a cohesive look—just make sure each spindle still meets local code for strength and spacing.

Building codes follow the 4-inch sphere rule, so balusters need to sit no more than 4 inches apart—about three per linear foot. That spacing keeps a 4-inch object from passing through, protecting kids and pets and keeping the railing up to code. Always double-check local requirements before you start, but using the 4-inch guideline will keep you in the safe zone.

Local building codes require that handrails be installed on stairways with four or more risers, ensuring safety and strong support. Even on stairs with fewer than four steps, handrails are strongly recommended for added durability and secure accessibility. Homeowners must consult local regulations to verify that handrail design, height, and placement conform exactly to official safety standards.

To determine the correct handrail measurements, measure the complete nosing line along the top of your steps and then mark a point between 34 and 38 inches above the floor for proper placement. This measurement ensures that your handrail is securely positioned, meets building code requirements, and provides optimal support and safety along the entire length of the staircase.
