If your timber floor feels bouncy, uneven, or soft underfoot, it’s a sign that something is wrong beneath the surface.
Across Bury, this is often caused by excess moisture in the sub-floor, leading to timber decay and structural weakening.
At Weather Wise Solutions, we carry out thorough inspections to identify the exact cause — whether it’s wet rot, poor ventilation, or hidden damp affecting the joists.
🔍 What Causes Timber Floors to Bounce or Sag?
Several issues can lead to unstable floors:
1️⃣ Wet Rot in Joists or Floorboards
Wet rot fungi thrive when timber moisture content rises above 20%.
It softens the wood, causing it to crumble or lose strength.
Common signs include:
-
Springy or spongy floorboards
-
Musty odour
-
Visible darkening or softness in joists
2️⃣ Poor Sub-Floor Ventilation
If air bricks are blocked, missing, or too small, moisture becomes trapped under the floor.
This increases humidity and leads to fungal decay, mould, and condensation in the void.
3️⃣ Rising Damp or Penetrating Damp Below Floor Level
Moisture entering from the walls, ground, or defective drains can saturate sub-floor timbers, accelerating decay.
4️⃣ Insect Attack (e.g., Wood-boring Beetles)
Timber weakened by damp becomes vulnerable to beetles, further reducing structural strength.
🧰 How We Fix Bouncy or Sagging Floors
At Weather Wise Solutions Limited, our inspection includes lifting floorboards (with permission) to check joists, wall plates, moisture levels, and ventilation.
Once we diagnose the cause, we may recommend:
✅ Replacing decayed timbers – only where structurally necessary
✅ Installing or restoring air bricks – to improve airflow and keep the void dry
✅ Treating rot and protecting remaining timber – using targeted biocides
✅ Addressing the moisture source – rising damp, leaks, or condensation
✅ Adding PIV or DMEV systems – to balance humidity throughout the home
We use trusted products from PAM Ties and Wycamol to ensure long-term protection.
