A marked wall, a yellowed ceiling, a stain that won't budge: the question comes up every time. Can it be cleaned, or does it need repainting? Getting it wrong is expensive both ways. Here's how to decide in five minutes.
The five-minute test
Take a clean cloth, warm water and a mild degreaser. Rub a small, discreet area for one minute — without forcing.
- The stain lightens noticeably → professional cleaning will handle the rest.
- Nothing moves, or the paint comes off with the stain → it needs repainting.
What cleaning actually fixes
- Kitchen grease on walls around the stove, even months old.
- Fingerprints around switches, handles and door frames.
- Built-up dust behind furniture and above cabinets.
- Shoe and furniture scuffs on baseboards.
- Cobwebs and dust in ceiling corners.
- Dried splashes in the bathroom and kitchen.
In all these cases, repainting would be wasted money. The wall is intact — it's just dirty.
What no amount of cleaning will fix
- Nicotine. The tar has soaked into the paint. Some comes off, but the yellowing and the smell return. Blocking primer, then paint.
- Water damage. The brown ring is in the material, not on it. Painted without special primer, it bleeds back through within weeks.
- Peeling or blistering paint. There's no surface left to clean. Scrape, sand, repair, repaint.
- Patched holes that still show. Plaster doesn't share the texture or sheen of paint.
- A ceiling yellowed by time. General yellowing isn't dirt — the paint itself has aged.
- Embedded furniture marks. Three years of a bed frame rubbing wears paint down to the substrate.
When cleaning must come before painting
There's a third answer, and it's often the right one: clean first, then paint what's left.
A greasy kitchen wall must never be painted directly — paint doesn't bond to grease and will crack or peel within months. The same applies to sanding dust after renovations, and to surface mould in a bathroom, which must be treated rather than covered.
That's exactly why we work in this order: we clean first, we paint when cleaning is no longer enough, we clean afterwards.
The cost comparison
- Deep cleaning one room, walls included: from about $90.
- Repainting one room, walls only: $275 to $425.
- Repainting one room, walls and ceiling: $425 to $575.
- Targeted touch-ups: $200 to $275.
Painting costs three to five times more than cleaning. The question isn't which is cheaper — it's which one will actually solve the problem. Cleaning a wall that needed paint means paying twice.
When in doubt
Send a photo. One image taken in natural light is usually enough to tell whether it needs cleaning, touch-ups or a full repaint — and to get a written price without a visit.
Our painting work is carried out by professional painters together with a contractor holding an RBQ licence. Our cleaning staff prepare the surfaces before and handle the cleaning after.
Key points
- The one-minute damp cloth test answers the question 80% of the time.
- Grease, fingerprints, dust, baseboards: cleaning is enough.
- Nicotine, water damage, peeling paint, yellowed ceilings: it needs paint.
- A greasy wall is never painted without degreasing first.
