The Coastal Deck Style Guide

The Coastal Color Palette

Everything starts with color.

Modern coastal spaces aren’t filled with bright blues and beach décor. Instead, they lean into warm neutrals, weathered wood, crisp whites, and muted blues that feel soft rather than bold.

Start with a Light, Natural Foundation

Every great outdoor space begins with the deck itself.

For a coastal-inspired backyard, lighter tones are your best friend. They reflect natural light, feel open and airy, and create the perfect backdrop for layered textures and soft colors.

At Weatherguard Decks, these are some of our favorite TimberTech® collections for achieving this look.

TimberTech® Harvest Collection – Coastline

If there were one decking color that perfectly captured this aesthetic, it would be Coastline.

Its soft gray-beige tones resemble weathered boardwalks and driftwood, creating a warm, relaxed foundation that feels equally at home beside a lake or in a suburban backyard.

It pairs beautifully with white railing, woven textures, hydrangeas, and classic blue-and-white textiles.

Best paired with:

• White Impression Rail

• Hydrangeas

• Teak furniture

• Navy striped cushions

• Linen umbrellas

TimberTech® Landmark Collection – Boardwalk

If your inspiration leans more toward charming New England cottages than polished beach houses, Boardwalk is a beautiful option.

Its natural color variation gives the impression of aged wood that’s been softened by years of sun and salt air. The result feels relaxed, welcoming, and full of character.

TimberTech® Vintage Collection – Weathered Teak

For homeowners who love the coastal look but want something a little more elevated, Weathered Teak offers incredible depth and realism.

Its rich wood grain adds warmth while still maintaining the soft, organic feel that defines coastal design.

Imagine the outdoor terrace of a luxury waterfront resort—that’s the feeling this color creates.
