Skirting boards that are rotting, crumbling, or soft at the bottom are a common issue in Sale homes — and it’s rarely just a decorative problem. In most cases, rotting skirtings are a clear sign of ongoing moisture affecting the timber, often from below floor level or from prolonged condensation at low wall heights.
Replacing the skirting boards alone won’t solve the issue. Unless the moisture source is identified and controlled, the new timber will often deteriorate in the same way.
At Weather Wise Solutions — a family-run damp and timber specialist — we regularly inspect properties where skirting damage is the first visible sign of a wider moisture issue.
🪵 Why Skirting Boards Rot from the Bottom
1️⃣ Subfloor Moisture Beneath Suspended Floors
In many Sale properties, suspended timber floors rely on good airflow beneath the building. If subfloor ventilation is restricted, moisture can build up below the floor and affect the base of walls and skirting boards.
2️⃣ Condensation at Low Wall Level
Cold wall surfaces combined with poor airflow allow condensation to form repeatedly at skirting height. Over time, this persistent moisture can soak into timber and cause decay.
3️⃣ Bridging Plaster
Where internal plaster runs down to floor level or bridges the damp-proof course, moisture can transfer into the wall and directly into the skirting boards.
4️⃣ External Moisture Influencing Internal Timbers
Raised ground levels, defective pointing, or external defects can introduce moisture into the wall base, which then affects skirting boards internally.
5️⃣ Poor Air Circulation
Furniture placed tight against walls can restrict airflow at floor level, allowing moisture to linger around skirtings and timber edges.
🔍 How We Diagnose Rotting Skirtings in Sale
Our inspections focus on identifying where the moisture is coming from, not just the damaged timber. This includes:
-
Moisture testing at skirting and wall base level
-
Inspection of subfloor conditions and ventilation
-
Assessment for condensation patterns
-
Checks for bridging plaster or finishes
-
External inspection to rule out penetrating damp
This ensures the correct cause is identified before any repairs are recommended.
🛠️ How the Problem Is Properly Resolved
Depending on the findings, solutions may include:
✔ Improving Subfloor Ventilation
Restoring airflow beneath the floor to reduce moisture levels affecting timber and walls.
✔ Addressing Condensation
Improving ventilation and air circulation to prevent moisture settling at low wall heights.
✔ Removing Bridging Materials
Ensuring plaster and finishes do not bridge moisture into the skirting boards.
✔ Timber Repairs
Only once moisture is controlled are decayed skirtings repaired or replaced.
