Composite Decking and Cable Railings: Are They Right for Your Lake House?

Composite decking and cable railings have become one of the most popular combinations on lake houses, and it is easy to see why. Composite boards cut down on maintenance, while thin stainless steel cables keep the view of the water wide open. Before you upgrade, here is what to know about each.

Composite Decking

Composite boards are made from a blend of wood fibers and plastic, and most quality boards today have a protective cap layer. They do not need sanding or staining, they will not splinter, and they resist rot and insects.

What to Consider

• Upfront cost: composite costs more than pressure-treated pine, though you save on staining over time
• Heat: dark colors can get hot in full afternoon sun, so lighter colors are popular on south- and west-facing decks
• Cleaning: composite still collects dirt, pollen and mildew, especially in shaded or damp spots near the water
• Framing: composite boards are installed over a wood or steel frame, and that frame needs to be sound

Cable Railings

Cable railings use horizontal or vertical stainless steel cables in place of wood or metal balusters. On a lakefront deck they are all about the view: thin cables almost disappear when you look past them toward the water.

What to Consider

• Material: marine-grade stainless steel holds up best in humid lakeshore air
• Tension: cables must be properly tensioned and periodically checked so they stay tight
• Code requirements: railings must meet local building code for height and spacing, including the rule that a 4-inch sphere should not pass through the opening
• Posts: cable systems put a lot of tension on the end posts, so posts have to be strong and well anchored

Can You Mix Wood and Composite?

Yes. Many homeowners keep a solid wood deck and simply add cable railings, or refinish existing wood boards while upgrading the railing. If your deck frame is in good shape, refinishing the boards and upgrading the railing can give you a fresh look for far less than a full rebuild.

Is It Right for You?

If you want more time on the deck and less time maintaining it, and the view is a big reason you live on the lake, composite decking and cable railings are worth considering. If you love the warmth of real wood, a well-maintained cedar or hardwood deck with cable railings is a beautiful middle ground. Compare options in our guide to choosing the best deck materials.
