If you’ve noticed soft, flaky, or crumbling timber around your window frames in Rochdale, it’s a strong indication of wet rot caused by moisture ingress.
Timber windows can last for decades when maintained properly — but once water gets into the grain, decay can spread quickly, damaging not only the frame but also surrounding plaster and masonry.
At Weather Wise Solutions, we investigate the cause of timber decay and repair or replace affected frames using safe, long-lasting methods.
💧 What Causes Timber Window Frames to Rot?
Timber rot is caused by a combination of moisture exposure and poor protection. The most common causes include:
1️⃣ Failing Paint or Sealant
UV damage, weathering, and age can break down paint or mastic, allowing water to soak into the exposed timber beneath.
2️⃣ External Water Ingress
Cracked render, defective pointing, leaking gutters, or damaged sills can direct rainwater straight into the window frame.
3️⃣ Condensation on Internal Surfaces
Moisture inside the property can condense on cold window reveals, feeding fungal decay from the inside out.
4️⃣ Poor Drainage or Blocked Weep Holes
Older timber windows often rely on simple drainage channels. If these are blocked, moisture sits in the frame and accelerates rot.
🧰 How We Diagnose Timber Decay in Rochdale Homes
At Weather Wise Solutions Limited, we carry out a full inspection before recommending any repairs. This includes:
-
Checking moisture levels in the timber using approved testing equipment
-
Examining paint systems for breakdown or hairline cracks
-
Inspecting external masonry for pointing defects, render cracks, or failed sills
-
Assessing ventilation levels to rule out internal condensation issues
-
Distinguishing wet rot from dry rot, ensuring correct treatment
This ensures we treat both the timber decay and the moisture source causing it.
