What does a Vancouver Cumaru tropical hardwood deck cost?

A Cumaru tropical hardwood deck in Metro Vancouver typically costs $80-$120 per square foot installed, making it one of the most expensive but longest-lasting decking options available. For a standard 300 square foot deck, expect to invest $24,000-$36,000 including materials, labour, footings, framing, and basic railing.

Cumaru, also known as Brazilian teak, is an ultra-premium South American hardwood that rivals Ipe for density and durability while costing slightly less. In Metro Vancouver's persistently damp climate, Cumaru's natural oil content and extreme density make it virtually impervious to rot, mould, and insect damage. The wood is so dense that it sinks in water and can last 40-60 years with minimal maintenance — making it an excellent long-term investment despite the high upfront cost.

Installation complexity drives much of the cost. Cumaru is extraordinarily hard and heavy, requiring pre-drilling for every single fastener, carbide-tipped saw blades, and experienced installers who understand tropical hardwood behaviour. Many general contractors lack the specialized tools and experience needed for proper hardwood installation. The wood dulls standard blades quickly and can crack if not pre-drilled correctly. Labour rates for Cumaru installation run $35-$50 per square foot in Metro Vancouver, compared to $15-$25 for cedar or composite.

Material costs alone run $25-$40 per square foot for quality Cumaru decking boards, depending on grade and width. The wood is imported from sustainably managed forests in Brazil and Bolivia, and supply can be inconsistent. Premium clear grades with minimal knots cost significantly more than standard grades. Most Vancouver suppliers stock 1x6 and 5/4x6 profiles, with wider boards available by special order.

Cumaru performs exceptionally well in Vancouver's marine climate because its natural oils repel moisture and the density prevents water penetration. Unlike cedar, which requires annual staining in our wet climate, Cumaru can go 3-5 years between maintenance cycles. When left untreated, it weathers to an attractive silver-grey patina similar to aged teak. However, Cumaru becomes slippery when wet unless the surface is grooved or lightly sanded annually — an important safety consideration for Vancouver's rainy months.

Additional project costs include specialized fasteners (stainless steel screws are essential and cost more than standard deck screws), potential structural upgrades (Cumaru's weight may require closer joist spacing), and longer installation time. Building permits still apply for any deck over 600mm above grade, and some municipalities may require engineered drawings for the additional dead load.

Consider the total cost of ownership when evaluating Cumaru. While the initial investment is 2-3 times higher than cedar, the dramatically reduced maintenance requirements and 40+ year lifespan often make it cost-competitive over time. A cedar deck requiring annual staining at $3-5 per square foot adds up quickly over decades.

This is strictly professional installation territory. The specialized tools, experience with tropical hardwoods, and structural considerations make Cumaru unsuitable for DIY installation. Choose a contractor with specific tropical hardwood experience and ask to see photos of previous Cumaru or Ipe installations.
