How to Change Stair Treads in Construction in the Netherlands

Stair treads play a crucial role in the safety, durability, and aesthetics of a staircase. Over time, due to wear and tear, structural damage, or design upgrades, it becomes necessary to replace stair treads in both residential and commercial buildings. In the Netherlands, where building codes (Bouwbesluit 2012) regulate stair construction, it is essential to follow proper procedures when changing stair treads.

This guide provides a detailed step-by-step process for removing and replacing stair treads, including materials, tools, regulations, and best practices to ensure a safe and efficient installation.

Understanding Stair Treads in Dutch Construction

A stair tread is the horizontal surface of a step where users place their feet. The thickness, material, and installation method depend on building regulations, staircase type, and usage requirements.

Common Stair Tread Materials in the Netherlands

• Wood (oak, beech, or pine) – Common in residential homes.
• Concrete – Used in commercial and industrial buildings.
• Metal (steel or aluminum) – Found in fire escapes and industrial settings.
• Glass or composite materials – Modern options for aesthetic staircases.

Before replacing stair treads, it is important to assess the structural integrity of the staircase and choose the appropriate material based on Dutch building codes and load-bearing requirements.

Tools and Materials Needed for Changing Stair Treads

Before starting the replacement process, ensure you have the following tools and materials:

Essential Tools

✔ Circular saw or jigsaw – For cutting new treads to size.
✔ Hammer and pry bar – For removing old treads.
✔ Measuring tape and level – Ensures precise alignment.
✔ Drill and screws – For securing new stair treads.
✔ Adhesive (construction glue or wood glue) – For extra stability.
✔ Clamps – To hold the treads in place during installation.
✔ Safety gear (gloves, goggles, and dust mask) – For protection during construction.

Materials Required

✔ New stair treads (wood, concrete, metal, or composite).
✔ Screws, nails, or anchors (depending on the material).
✔ Wood filler or sealant (for finishing wooden staircases).
✔ Anti-slip strips or coatings (for added safety).

Once all materials and tools are gathered, proceed with removal and installation.

Step-by-Step Guide to Changing Stair Treads

Step 1: Assess the Existing Staircase

Before removing old treads, inspect the staircase for:

• Structural damage (loose risers, weak framing, or cracked supports).
• Rot, warping, or termite damage in wooden staircases.
• Compliance with Dutch safety regulations (correct rise and run dimensions).

If major repairs are needed, fix the underlying stair structure before installing new treads.

Step 2: Remove the Old Stair Treads

• Use a pry bar and hammer to carefully lift the old tread without damaging the stringers or risers.
• If treads are nailed or screwed, remove them using a drill or crowbar.
• For concrete stairs, use a chisel and hammer to break apart the old tread.
• Clean the stair frame and remove debris, old adhesive, or nails before installing new treads.

Step 3: Measure and Cut New Stair Treads

• Use a measuring tape to determine the exact dimensions of the old tread.
• Cut the new treads to size using a circular saw or jigsaw.
• If replacing with concrete treads, ensure precise molding and curing before installation.

For wooden staircases, consider pre-finishing the treads with varnish or protective coatings before installation.

Step 4: Secure the New Stair Treads

Depending on the staircase type and material, follow the appropriate installation method:

✔ For Wooden Stair Treads:

• Apply construction adhesive to the stair frame.
• Secure with wood screws (countersink them to avoid protrusions).
• Use clamps to hold the tread in place while the adhesive sets.

✔ For Concrete Stair Treads:

• Use concrete anchors to fasten the treads.
• Apply a bonding agent to ensure adhesion to the staircase.

✔ For Metal or Composite Treads:

• Attach using bolts and metal brackets for stability.
• Ensure proper anti-slip coating for safety compliance.

Use a level to check alignment and make adjustments before securing the treads permanently.

Step 5: Finishing Touches

• Fill gaps with wood filler or sealant (for wooden stairs).
• Install anti-slip strips to enhance safety, especially for commercial buildings.
• Sand and paint for aesthetic finishing.
• Test stability by applying weight to ensure proper installation.

Regulations and Safety Standards for Stair Treads in the Netherlands

In the Netherlands, stair tread replacements must adhere to Bouwbesluit 2012 and NEN 3215 safety regulations. Key requirements include:

✅ Tread depth: Minimum 220 mm for residential buildings.
✅ Tread width: Must match the existing stair dimensions.
✅ Anti-slip measures: Required for commercial and public buildings.
✅ Fire resistance: Stair materials must comply with NEN-EN 13501 fire safety standards.
✅ Load capacity: Treads should support at least 2.5 kN per m².

Failing to comply with these regulations may result in fines or safety violations.

Common Mistakes to Avoid When Changing Stair Treads

🚫 Skipping structural inspection – Weak stringers or loose risers can lead to unstable stairs.
🚫 Using incorrect materials – Some woods are unsuitable for high-traffic areas.
🚫 Ignoring anti-slip coatings – Can cause safety hazards, especially in public spaces.
🚫 Failing to level the treads – Leads to uneven steps and discomfort.
🚫 Not securing treads properly – Loose treads increase accident risks.

Following best practices ensures a safe, durable, and code-compliant installation.

Conclusion

Changing stair treads in Dutch construction requires careful planning, compliance with building codes, and precise installation. Whether upgrading wooden, concrete, or metal staircases, ensuring proper material selection, accurate measurements, and secure fastening is essential for safety and longevity.

By following this step-by-step guide, homeowners and contractors can efficiently replace stair treads while meeting Dutch construction regulations and enhancing the functionality and aesthetics of the staircase.
