Here's what we were working with - an older weathered deck next to a pool that had seen better days on Cape Cod. The wood had gone gray and flat, and the whole space just wasn't doing the backyard justice. The homeowner wanted something that could take whatever Cape weather throws at it while still looking sharp enough to actually enjoy. That's where Cumaru comes in.
Cumaru is a South American hardwood - and it's one of the toughest decking materials you can put in the ground. It's denser than most domestic hardwoods, naturally resistant to rot and insects, and it holds up against moisture the way few other wood species can. For a pool deck on the Cape, where you're dealing with humidity, salt air, and freeze-thaw cycles, it's honestly one of the best choices you can make. The rich reddish-brown color right out of the gate doesn't hurt either.
What made this one interesting was the layout. The deck wraps around the pool area in a curved, free-flowing shape - which means a lot of angled cuts, mitered corners, and careful planning to get the boards to line up cleanly. You can see the chevron-style detail where two sections of the deck meet. That kind of joinery doesn't happen by accident. Every angle has to be thought through before a single board gets fastened down.
We also tied the deck into the existing front porch entry with new Cumaru steps and treads - clean white risers, tight mitered corners on the step nosing, all finished to match the main deck surface. The goal was to make the whole exterior feel like one cohesive design rather than a collection of separate add-ons. As a full exterior renovations crew, this is exactly the kind of scope we plan for from the start.
The difference between the old deck and the new one is night and day. What used to be a faded, tired surface is now the centerpiece of the backyard - something the homeowners are going to be proud of for a long time. Cumaru only gets better with age when it's maintained properly, and a deck like this is built to outlast most of the alternatives on the market.
