Why Garden Rooms Are at Risk of Wet Rot
Garden rooms, extensions, and outdoor timber buildings are increasingly popular in Southport homes. However, because these structures are more exposed to the elements, they are particularly vulnerable to wet rot.
Moisture from leaks, poor ventilation, or ground contact can quickly raise timber moisture levels, allowing fungi to attack and break down the wood.
How to Spot Wet Rot in Garden Room Timbers
Look out for:
✅ Soft, spongy, or crumbling wood
✅ Darkened or discoloured patches in the timber
✅ A damp, musty smell inside the garden room
✅ Cracking or shrinking around timber joints
✅ Peeling paint or finishes that won’t stick
Why It Happens
Common causes of wet rot in garden rooms include:
-
Poor roof coverings that allow leaks
-
Inadequate damp proofing where timbers meet the ground
-
Condensation build-up due to lack of ventilation
-
Guttering or drainage problems leading to water pooling
