Humphrey's Building Supply


Wood is the traditional choice for beautiful decking projects. Humphrey's stocks a fine selection of Garapa, Ipé and red Balau mahogany guaranteed to withstand Rhode Island's elements and provide outdoor enjoyment for years to come.


Garapa: The Gold Standard in Tropical Hardwoods
100% Clear All-Heartwood. Similar to Ipe in density and gold in color, Garapa decking is beautiful, very stable and highly durable, making it an ideal choice in wood decking. It is resistant to rot, decay, splinters and scratches– without chemical treatments. The warm golden tones make Garapa wood a lighter colored natural wood decking option.

Ipe Decking

Ipé Decking

Premium Ipé wood decking is the toughest, longest-lasting decking material available. Its natural oils and dense, tight grain repel rot, moisture, mold, decay and insect infestation while providing an extremely durable surface that resists scratches, slivers and slips. A beautiful rich brown with red and amber hues, Ipé is available in regular boards, tongue-and-groove and pre-grooved board profiles.

Red Balau Mahogany

Red Balau Mahogany is a popular type of decking wood used by most architects, builders and homeowners. It's a water-resistant, durable, sturdy wood and four times harder than the common redwood. It is resistant to decay, molds and insect attacks and extreme weather conditions, making it ideal for the construction of boat docks, bridges and ramps.


Accoya modified wood has become the timber industry benchmark when it comes to performance and sustainability. No other timber offers the same combination of durability, stability and versatility. Sustainably sourced, and with a low total lifetime carbon cost, Accoya actively contributes to a circular, bio-based economy and is one of the few truly sustainable building materials.

Pressure Treated

Pressure treated wood contains chemical preservatives to prevent rot and insect infestation for outdoor applications such as decks. It has a long and useful lifespan of up to 40 years and is much less expensive than alternatives. The treatment process involves placing a load of lumber in a cylindrical container and then forcing waterborne chemicals into the wood under pressure.
