If you’ve noticed a damp smell under the stairs but nowhere else in the house, it can feel very specific and hard to explain.
Localised smells in enclosed spaces often point to hidden moisture in that area.
This is exactly where our Leak Detection service helps identify what’s happening behind the scenes.
What This Usually Means
Moisture is likely building up in that enclosed space, even if nothing is visible.
Smells often appear before visible damage.
Why This Happens
Enclosed areas trap moisture, making smells more noticeable.
