What Teak Wants in a Costa Rican House

A piece of old teak has already survived more weather than any of us will. The tables and cabinets we brought back from Java were often eighty or ninety years old before they reached us, cut in the Dutch colonial decades, worked by hand in the joinery towns around Jepara and Surabaya. Wood that has held its shape through that many wet seasons on the island is not fragile. But it is alive, and it responds to where it lives. Costa Rica is not Java, and the first thing to understand is what the difference asks of the material.

What the wood already knows

Teak earns its reputation from the inside. The tree lays down natural oils and silica in the grain, and those oils are why a teak deck on a boat can go decades without rot. Reclaimed teak — the beams and floorboards and old furniture we sourced across Central and East Java — has usually spent its life reaching equilibrium with tropical air. It swelled in the rains and settled in the dry months, year after year, until the movement became small and predictable. That long seasoning is the reason old teak sits so quietly. New teak, kiln-dried and fast to market, has not learned this yet.

Suar, the wide monkeypod you see in single-slab tables, behaves differently. Its figure is dramatic, the sapwood pale against a dark chocolate heart, and it holds more water in its cells than teak does. A suar slab wants to move more, and it wants time. This matters the moment a piece changes climate. A cabinet that lived in the highlands above Ubud, cool and misted, and then travels to the Central Valley, is entering a new agreement with the air. Give it several weeks in the room before you judge it. A hairline gap that opens at the coast may close again in Escazú. The wood is negotiating, not failing.

The Costa Rican variable

The enemy here is rarely dryness. It is swing. A house open to the breeze in Guanacaste, or a beach property that runs the air conditioning hard for a weekend and then sits shut and humid for a week, forces the wood to expand and contract on a short cycle. That is what loosens a joint over years, not the humidity itself. Old Javanese furniture was built for movement — mortise and tenon, pegged, sometimes with breadboard ends that let a tabletop breathe across its width. Those joints work with the wood rather than pinning it. What they cannot tolerate is being asked to move fast and often.

So the care is mostly about steadiness. Keep pieces out of the path of direct afternoon sun, which will bleach the surface unevenly and drive one face of a panel drier than the other. Keep them off the vent of an air conditioner. In a coastal house, a slow ceiling fan does more good than a sealed, over-cooled room, because gentle air movement discourages the mildew that finds any still, damp corner in the green season. Dust with a soft dry cloth, and when you wipe a spill, dry it after. Standing water is the one thing old teak has not made peace with.

The oil question, and doing less

People reach for teak oil out of affection, and it is usually the wrong instinct indoors. Old teak that has developed a soft patina does not need to be fed. Oiling it too often builds a sticky film that traps dust and darkens unevenly, and in humidity that film can go tacky. A well-cared-for antique piece may want nothing more than a light paste wax once or twice a year, buffed by hand, on a dry day. That is the whole ritual. If a surface looks thirsty and grey, a single sparing application of a good furniture oil, wiped back hard so nothing remains on the surface, is enough — and then leave it alone.

Suar tables with an oil finish are the exception that proves the rule: they genuinely benefit from a thin refresh where the finish has worn at the elbows and edges. Even then, restraint wins. Most damage we see in the Central Valley comes not from neglect but from too much attention applied too anxiously.

The pieces we live with in Escazú have all made this crossing and settled. To understand how a ninety-year-old teak cabinet or a single suar slab actually reads in a Costa Rican room — the weight, the patina, the way the light finds the grain — the honest thing is to stand in front of one. We keep the collection in our showroom-home, and visits are by appointment.
