Why Staircases Are Vulnerable
Staircases are one of the most important structural features in a home — but also one of the most overlooked when it comes to timber decay. In older Bolton properties, stair strings, treads, and risers are often made from softwood, which makes them a prime target for wood-boring beetles, commonly referred to as woodworm.
Signs of Woodworm in Staircase Timbers
If you’re concerned about your staircase, look out for:
✅ Tiny exit holes (1–2 mm in diameter) along the stringers or underneath treads
✅ Fine powdery frass (bore dust) collecting on steps or nearby floors
✅ Creaking or weakened steps when weight is applied
✅ Splitting or crumbling timber when inspected closely
✅ Adult beetles emerging during warmer months
These symptoms can indicate active or historic infestation — a professional inspection is the only way to be sure.
Risks of Ignoring the Problem
Staircases are load-bearing and take constant daily use. Left untreated, woodworm can weaken the structural integrity of steps and stringers, making them unsafe.
