Define Your Needs and Preferences

What will you mainly be using your deck for? Your usage can impact the type of railing you choose. Also, consider the architectural style of your home and deck. Choose a railing that compliments the overall design, enhancing the visual appeal of your outdoor space.

If you have children or pets, think about the safety features of deck railings. Ensure that the spacing is narrow enough to prevent children or pets from slipping through them.

You should select durable and safe materials for deck railings. Aluminum railings are better for homes with kids or pets. Natural wood railings might not be the best option since they can splinter and crack after time if not properly maintained.


Caution

Wide gaps between deck railings are unsafe for children and pets. Verify the gap and height of the railing with your local code before installation.

​Research Local Building Codes

Check local building codes and regulations regarding deck railings. Make sure that the height, spacing and load-bearing requirements meet safety standards. Typical codes include a minimum height of 36 inches and baluster spacing no more than 4 inches.

Explore Different Railing Types and Materials

Research all types and materials for deck railings. Your first choice may not be the best option for your space. Think about how different materials reacts to various weather conditions and wear. For example, wood gives a natural and rich finish. However, aluminum, metal, and composites last longer and require less care. Choose the one that best matches your needs.

Match Your Budget

Evaluate the costs of different types of deck railings. Factor in if the material will require more care and possible replacement over time. Wood and vinyl are more budget-friendly. Metals, composite or aluminum may save you money overall.

Evaluate Aesthetic and Design Options

Select colors and finishes that enhance your home’s curb appeal. You can find many shades and styles to match your design choices. You should also factor in things like decorative balusters, post caps or lighting. These can boost the visual appeal and how your railing will look.

Consider Adding Deck Lighting

Adding built-in lighting features can add to the look of your deck in the evening. For example, solar LED post-cap lights or rope lights can add illumination is a subtle way. Make sure the lighting goes with the railing design, especially if it is hard-wired lighting. There should be enough brightness for safety without harming the ambiance.

Review and Finalize Your Decision

Review your options. Compare all materials for deck railings, costs and designs. Make sure your choice aligns with both your aesthetic preferences and practical needs. Once you’ve decided, Lowe’s is here to provide you with the selection and materials to make your project a success.

Things to Consider When Choosing Deck Railings

By considering the following factors outlined, you can enhance how your deck looks and increase its safety:

  • Safety Regulations: Most local building codes require a minimum railing height of 36 inches for decks. This height ensures safety and stops people from falling. The spacing between balusters (vertical posts within the railing) should not exceed 4 inches. It stops children or pets from squeezing through the gaps and falling off the deck. For example, aluminum or steel railings are strong enough to fight extra force levels.
  • Aesthetic Compatibility: Select a color that blends well with your deck. Match the railing style to your home's architecture (modern, traditional and rustic). Materials like wood and glass look the best. They add a sleek look that complements your deck and home.
  • Budget: Plan for both initial installation costs and long-term care expenses. Consider the lifespan of the railing relative to its cost. For example, vinyl and composite railings are low maintenance and offer good value for money.
  • Sustainability: Get eco-friendly stains and finishes with lower volatile organic compounds (VOCs) for wood railings. Look for the Forest Stewardship Council (FSC) certifications label. They make sure the wood is harvested in a responsible way. You can also opt for composite railings, which are made from recycled elements like sawdust, wood chips and wood shavings.
