We often associate damp with the obvious—dripping water or a flooded basement. However, in most homes across Wiltshire, damp is a “slow burn” problem. It starts small, often behind furniture or in corners that rarely see the light of day, and it can remain undetected until the damage becomes significant.

As independent surveyors, we see the consequences of missed warning signs every single day. Here is how you can spot damp before it turns into a major repair bill.

1. The “Musty” Smell

If you walk into a room and notice a lingering, earthy, or “musty” odour, don’t just reach for the air freshener. This is often the first indicator of hidden moisture or mould growth behind wallpaper or beneath floorboards. If the smell persists despite good ventilation, it’s time to investigate further.

2. Peeling or Bubbling Decor

Are your walls showing signs of peeling wallpaper, bubbling paint, or “tide marks” near the skirting boards? These are classic symptoms of dampness within the plaster. While it might look like a cosmetic issue, it is usually a sign that moisture is trapped in the structure of the wall.

3. Condensation on Windows

While condensation on your windows during a cold morning is common, it should clear quickly. If your windows are constantly “weeping” or if you see black spots of mould forming on window frames or in the corners of ceilings, you likely have a ventilation issue. If left untreated, this excess moisture can lead to serious respiratory issues and structural decay.

4. “Cold” Spots

Have you noticed that a particular wall or corner of a room feels significantly colder to the touch than the rest of the house? Damp materials conduct heat away from the surface much faster than dry ones. If you notice a “cold spot,” it could be a sign of moisture penetration.

Don’t Wait for the Damage to Grow

Many homeowners make the mistake of calling a “damp-proofing company” as soon as they see a mark on the wall. The problem? If that company is incentivized to sell you a chemical injection or a tanking system, they will likely tell you that you need one—even if the actual cause is something as simple as a broken gutter or a blocked air brick.
