Not Every Beam Is Oak

Restoring beams in Potton homes and softwood timber frames.

Most of what we write about is oak, because most period properties are oak. But a good number of self-builds and 1970s–1990s timber-frame houses were built with softwoods — Douglas fir, pine, spruce — and those beams don't behave the same way under treatment. Here's what's actually different.

Restored oak beam and post, Potton self-build showhome, Caxton

We've worked on the exposed oak frame in Potton's self-build showhomes at Caxton & Gransden, Cambridgeshire, for more than 20 years — the timber-frame construction Potton is known for. But "timber frame" and "self-build" cover a lot more than oak. Anyone with a 1970s–1990s character property, or a kit-built timber-frame house from that era, is more likely to be looking at Douglas fir, pine, or another softwood — and that changes how it should be treated.

Softwood isn't just "lighter oak"

Douglas fir and pine have a different grain structure to oak: softer fibre, more resin content, and a tendency to tear rather than release cleanly if the wrong technique is used. A method calibrated for hard, dense oak can be too aggressive for softwood, pulling up fibre and leaving a rough, uneven surface instead of a smooth one. Softwoods need a lighter touch and a process that respects how much more easily the surface responds.

What we're bringing out is different, too

Where the goal on oak is usually to brighten dark staining or paint back to a rich, warm brown, softwoods like Douglas fir and pine naturally sit in a lighter, honey-gold range. Stripping them back too hard — or with a method built for oak — tends to push them towards a harsh yellow or bleached-white finish that looks stripped rather than restored. The aim with softwood is the same as it is with oak: reveal what's actually there, rather than force a colour onto it.

Oak and softwood aren't the same problem with a different name. They need different judgement calls at every stage.

What stays the same regardless of timber

Whatever the species, our process is applied entirely by brush — nothing sanded, nothing blasted, nothing to clear up — water-based and non-hazardous, with no need to move out of the house while it's done. Whether it's oak in a Kent farmhouse or Douglas fir in a self-build timber frame, the same principle holds: the treatment works on the surface, not through it, so nothing structural is removed and any existing character in the wood is preserved rather than sanded away.

If you're not sure what you're looking at

Plenty of homeowners genuinely don't know whether their beams are oak, pine, Douglas fir, or something else — and it's a perfectly reasonable question to ask before doing anything. Send us a couple of photos by WhatsApp or email and we'll tell you honestly what timber you've likely got and what's realistic for it, including if the honest answer is that a different approach entirely is the right one.

Before you call

We will tell you if it is not worth doing.

We take few projects at a time, because each one is worked personally rather than scheduled around. That means an honest answer costs you nothing and saves us both a wasted visit.
