“I’ve noticed cracks in the timber… should I be worried?”
This is something we get asked a lot in Burton-on-Trent — especially in older properties where timber has been in place for decades.
The truth is:
👉 Not all cracks in timber are a problem.
In many cases, cracking is completely natural.
But sometimes, it can be a sign of something more serious.
At Weather Wise Solutions — a family-run damp and timber specialist — we help homeowners understand the difference between harmless movement and genuine decay risk.
🪵 Why Timber Cracks in the First Place
Timber is a natural material, which means it responds to its environment.
Over time, it will:
- Expand when it absorbs moisture
- Shrink as it dries out
👉 This movement can cause cracking — especially in structural timbers.
✅ When Cracking Timber Is Nothing to Worry About
In many Burton-on-Trent homes, cracks are simply due to:
1️⃣ Natural Shrinkage
As timber dries over time, it can form:
- Long, straight cracks (known as checks)
- Surface splits that follow the grain
👉 These are very common and usually harmless.
2️⃣ Seasonal Movement
Changes in temperature and humidity can cause timber to:
- Expand in winter
- Contract in summer
This can lead to minor cracking that doesn’t affect strength.
3️⃣ Older Timber Settling
In older properties, timber has often already gone through decades of movement.
👉 What you’re seeing may have been there for years without issue.
⚠️ When Cracking Timber Might Be a Problem
This is where proper diagnosis matters.
Cracking becomes a concern when it’s linked to moisture and decay.
1️⃣ Soft or Spongy Timber
If the timber:
- Feels soft when pressed
- Can be easily indented
- Appears fibrous or crumbly
👉 This may indicate wet rot or fungal decay
2️⃣ High Moisture Levels
From a PCA perspective:
- Below ~16% WME → low risk
- 16–20% → at risk
- Above 20% → conditions suitable for decay
👉 Cracking combined with high moisture is a warning sign.
3️⃣ Irregular or Expanding Cracks
Cracks that:
- Widen over time
- Appear uneven or distorted
- Are accompanied by movement in the structure
👉 May suggest underlying structural or moisture issues.
4️⃣ Associated Signs of Damp
Look for:
- Damp smells
- Discolouration
- Mould growth nearby
- Poor ventilation
👉 These often point to the root cause rather than the crack itself.
🧠 The Key Principle
👉 Cracks don’t cause problems — the conditions around them do.
Timber decay is driven by:
- Moisture
- Lack of ventilation
- Sustained damp conditions
Not just the presence of cracks.
🔍 How We Assess Cracking Timber in Burton Homes
At Weather Wise Solutions, we don’t jump straight to treatment.
We assess:
- Timber moisture content
- Signs of fungal decay
- Ventilation around the timber
- Structural integrity
- Environmental conditions
Our surveyors are CPD qualified in Dampness in Buildings, with several holding Level 3 qualifications in damp and timber inspection, ensuring accurate and responsible diagnosis.
🛠️ What Actually Fixes the Problem
If there is an issue, the solution is usually:
✔ Removing the source of moisture
✔ Improving ventilation
✔ Allowing timber to dry naturally
✔ Only treating or replacing timber where necessary
👉 Over-specifying timber treatment is one of the most common mistakes in the industry.
