Identify the stain type
We determine whether the stain is from water, mould, smoke or age so it is treated correctly.
Ceiling Problems
Ceiling stains are usually a moisture mark, not just a cosmetic blemish. Renovix treats the cause and restores a clean ceiling.
What This Problem Means
A clear, honest explanation of what is happening so you know what you are dealing with.
A ceiling stain is a discolouration on the ceiling, most often a yellow-brown water mark, but it can also be a dark patch from mould, a damp spot, or a greyish area from old smoke or dirt. A water mark is the most common type and is a sign that moisture is coming through the ceiling from above. Left untreated, that moisture can spread, weaken the board and, in some cases, lead to a sag or a leak.
Ceiling stains are easy to ignore because they are often high up and out of the way, but they should not be painted over without finding the cause. If the underlying moisture is still present, the stain will bleed back through, the paint will bubble, or the damp will spread. A lasting fix finds and stops the moisture, then cleans and repaints the affected area.
The short answer
Ceiling stains are usually a moisture mark, not just a cosmetic blemish. Renovix treats the cause and restores a clean ceiling.
We explain the cause and the fix, not just the symptom.
Common Causes
Understanding the cause helps you know why it happened and what the right fix is.
A slow leak from a roof, pipe or fixture above the ceiling.
Condensation and humidity in a bathroom or kitchen ceiling.
Old water damage that was never fully treated or repainted.
Mould or mildew growing in the damp area.
Smoke or soot staining from a cooking or heating source.
Dirt and age discolouring the ceiling over time.
Warning Signs
Spotting these signs early can often prevent a small problem from becoming a larger repair.
A yellow-brown or dark patch on the ceiling that grows slowly.
The stain darkening or spreading after a heavy rain.
A stain accompanied by bubbling paint or a damp smell.
Multiple stains or a stain that is soft to the touch.

FAQs
Straight answers to the questions customers ask us most about this problem.
Not reliably. If the stain is from water, the moisture can still be present and the stain will bleed through. A stain blocker and stopping the cause give a lasting result.
That usually means there is still a moisture source feeding the stain. Painting over it repeatedly will not help — the leak needs to be found and fixed.
Most water-mark stains are, but stains can also come from mould, smoke or age. We identify the type so the right treatment is used.
An active stain tends to grow, darken or spread after rain or heavy use. If it feels damp or smells musty, the moisture is probably still there.
If the stain is properly treated and sealed and the moisture source is stopped, it should not show through. That is why we treat the cause, not just the surface.
