Installing custom stair railings can transform both the safety and style of your staircase. Whether you're enhancing a modern home or updating a traditional layout, properly installed railings add structure, elegance, and value to your space. At Demose, we specialize in custom stair solutions—including railings designed to meet your style, space, and safety needs.
In this guide, we walk you through how to install custom stair railings the right way.
Why Proper Stair Railing Installation Matters
Stair railings aren't just a design element—they're a safety feature. Improper installation can lead to wobbly supports, building code violations, and potential accidents. That's why every custom railing project from Demose is designed and engineered for:
Stability
Safety compliance
Visual harmony
Long-term durability
Even if you're a DIY enthusiast, having a clear, professional guide is key.
Tools and Materials You'll Need
Before you begin, make sure you have the following tools and materials ready:
Tools:
Measuring tape
Level
Drill and bits
Wrench set
Saw (if rail length adjustments are needed)
Screwdriver
Safety glasses and gloves
Materials (may vary by railing type):
Custom rail sections (wood, metal, or glass)
Posts or balusters
Handrail brackets
Mounting hardware (screws, anchors, bolts)
Adhesive (for certain systems)
Touch-up paint or finish (optional)
Step-by-Step Installation Guide
Step 1: Plan and Measure
Begin by measuring the length and angle of your stairs. Determine the number of balusters and posts needed based on local building codes (usually one every 4 inches).
Pro Tip: Custom railings from Demose are pre-engineered to match your measurements, saving time during installation.
Step 2: Mark Post Locations
Mark where each newel post (main support post) will go. Usually, one at the bottom and top of the stairs, plus any turns or landings.
Use a level to ensure all markings are vertical and aligned.
Step 3: Secure the Posts
Drill pilot holes and anchor the newel posts into the floor or stair tread using bolts or mounting plates.
Make sure the posts are perfectly vertical, as they set the foundation for the rest of the railing.
Step 4: Install the Handrail Brackets
Attach the handrail brackets to the wall or posts, according to your design. Brackets should be evenly spaced and installed at the height required by building codes (typically 34–38 inches above the stair nosing).
Step 5: Attach the Handrail
Mount the custom handrail onto the brackets. If needed, cut the railing to fit your measurements.
Secure the handrail using screws or bolts. For glass or metal railings, follow manufacturer instructions or consult with Demose's technical team for best practices.
Step 6: Install the Balusters or Infill
Install balusters (vertical rods or panels) between the handrail and stair tread, or add your chosen infill (like horizontal bars or glass panels). Spacing should meet safety standards.
Many Demose systems use concealed fasteners or easy-connect hardware to simplify this step.
Step 7: Final Adjustments and Touch-Ups
Check all components for stability and alignment. Make any necessary adjustments.
Finish by tightening all bolts and touching up with paint or polish, if needed.
