Are you keeping your timber stocks dry?

Top tips on how to protect your timber and prevent wastage

The exceptionally wet start to 2026 has made one thing very clear for merchants: protecting timber stocks from moisture is more important than ever. Prolonged rainfall, saturated ground conditions and consistently high humidity have created a far more challenging environment for merchants and builders alike, with even short periods of exposure now capable of causing lasting damage to building materials.

Careful storage has always mattered when handling timber, but in prolonged wet weather it has taken on greater importance. Timber performs best when its moisture content remains stable, yet damp air and repeated wetting increase the risk of swelling, warping and fungal growth. Even well-graded timbers can quickly deteriorate if left exposed for too long, which is why checking moisture levels on delivery and maintaining control over storage conditions should be routine.

Indoor storage remains the safest option, provided the space is properly dried out and ventilated rather than affected by wet trades or uncured concrete. Where outdoor storage is unavoidable, it’s vital to get the fundamentals right. Packs should be raised on bearers, kept clear of standing water and protected with breathable waterproof covers that shield against rain while still allowing airflow. Small details such as avoiding trapped condensation or ensuring even support across a stack can make a noticeable difference.

More sensitive products, such as joinery items and sheet materials, require an added level of care. Keeping them flat, dry and in conditions that reflect their final environment helps to prevent movement after installation, while factory finishes should remain wrapped until needed to avoid unnecessary damage.

Transport is another point where problems can arise, with the risk of timber getting wet or damaged on its way to site. Timber should be loaded onto clean, dry vehicles, secured without excessive pressure and protected using breathable sheeting to guard against both rain and condensation.
After such a wet start to the year, consistent attention at every stage, from delivery through to installation, is what keeps timber in good condition and ready for use across the UK.
