Materials & Timber

Guides in this hub

• The label tells you the tree, not where it has been

  A timber label like "oak" or "pine" tells you the species, not the journey. A lot of stair timber is shipped abroad for processing before it returns as "product", so here is what to ask about where your timber was grown and processed, and why it matters.

• Glass balustrades: why the joinery and fixings matter more than the glass

  On a glass balustrade the glass is the easy part. What makes or breaks it is a dead-square, parallel frame (ideally tenoned and drawbored, not just screwed) and silicone bedding the glass so it is cushioned, held plumb and does not rattle.

• Which timber to choose for a staircase

  The best timber for a staircase depends on the part. Treads need a harder, wear-resistant wood like oak, ash or beech; handrails reward a timber that feels good in the hand; and paint-grade softwood is fine where it will be covered. There is no single best wood, and hardness is a guide, not a regulation.

• Metal spindles: cheaper than you think, and why simple lasts

  Metal spindles are more affordable than their reputation suggests, so they are worth a look on cost. But the more elaborate the design the faster it dates, so a simple, plain metal spindle tends to stay looking right far longer.

• Painting your stairs? What they should actually be made of

  If you are painting a staircase the material underneath still matters. Treads should be solid pine, never MDF. Risers are best solid, with plywood a sound second and MDF the one to avoid. Here is why paint hides the look but not how the material behaves.

• Is your timber sustainable? Legality, and what FSC or PEFC certified really means

  Legally sourced and sustainably sourced are not the same claim, and being FSC or PEFC certified is about audited paperwork, not a guarantee every board came from a certified forest. Here is what the labels really mean.

• Responsibly sourced timber: what actually stands up, and what is greenwash

  Beyond an FSC or PEFC label, a responsibly sourced claim only means something if it is specific and evidenced. Chain of custody to a named woodland, audited sawmills, Grown in Britain and reclaimed for non-structural parts stand up. Slow-grown-so-stronger and local-is-always-greener do not.

• Finishing a wooden staircase: oil, hardwax oil, varnish and lacquer

  For a natural-finish timber staircase the main choice is a penetrating oil or hardwax oil versus a surface film like varnish or lacquer. Oils are easier to repair in patches; films look harder but wear through at the nosings and have to be stripped to redo. Slip depends on the finished surface, not the type alone.

• Why timber stairs creak, gap and move, and how moisture content prevents it

  Timber moves as it gains and loses moisture, so a staircase can open small seasonal gaps and creak as the heating comes and goes. The prevention is fitting it at the right moisture content for a heated home, around 8 to 12 percent, and letting it acclimatise first, not the wood failing.

• Hardwood or softwood for a staircase: when each is the right choice

  Hardwood is not automatically better for stairs. The real choice is exposed versus covered: for a natural, on-show timber stair a hardwood like oak wears better, but for a painted or carpeted stair a good softwood is the right choice, not the lesser one.

• Carpet or exposed wood stairs? The practical difference

  Whether to carpet stairs or leave them as exposed wood is mostly a practical decision, not just a look. Carpet is quieter, warmer underfoot and more forgiving if you slip; exposed wood shows the timber and wears well but can be slippery and noisier. What the stair is made of underneath matters either way.
