About Our Decks: The Dec-Tec Difference

Want to know more about why Seattle homeowners love our decks so much? It’s because we rely on only the best decking manufacturers for every installation. We use Dec-Tec products because they’ve been providing the highest quality walkable deck solutions for more than 30 years.

Let’s look at exactly what they have to offer, and why they are our go-to product for every installation.

Dec-Tec Product Lines

Dec-Tec products are renowned for their waterproof properties, durable nature, and amazing warranties. Here are the three lines that we install:


Looking for a traditional esthetic that will go with just about any existing style or design? The Classic Line is for you. These come in neutral colors: bronze, granite, solid grey, and brick. And they work well for anything from a deck or patio to your boathouse. The Classic Line is the perfect combination of comfort, protection, and style.


Dec-Tec’s Natural Line is designed to look—well, natural! With patterns like Ivory Travertine, Kwila, and Southern Oak, your deck will be one with Mother Nature. Don’t let the organic beauty fool you, though. These decks are still sturdy enough for residential and commercial applications due to their unique Real Technology (patent pending) featuring UV protection and a fibreglass core.


Coolstep decks are ideal for pool decks or anywhere else you want to keep your bare feet from blazing on a hot summer day. It features light pattern membranes designed to reflect more solar rays than traditional decking. And it comes in 4 neutral patterns: Coolstep, Coolstep Copper, Coolstep Slate, and Coolstep Sandalwood.
