Construction methods & mould

Severe mould growth forming on a damp interior wall caused by poor ventilation and hidden moisture.Why Portuguese Homes Are Prone to Mould

After inspecting countless homes across Cascais, Estoril, and Sintra, I’ve seen firsthand how Portuguese construction methods make mould more common.In South Africa, most homes are built with cavity walls, which provide an air gap that helps block moisture. In contrast, Portuguese homes typically use solid concrete block walls. While sturdy, they lack that protective air barrier - meaning moisture can easily seep through exterior paint and settle inside walls.

Key Insight: Paint alone doesn’t waterproof a house. Without a proper damp-proof layer, even freshly painted walls can absorb moisture and start showing mould over time.

How Mould Becomes a Problem

• DAMP, MOI STURE & MOULD Roof Leaks: Cracked tiles or faulty flashing allow rainwater to enter unseen.

• Plumbing Leaks: Hidden leaks inside walls or under sinks feed mould growth.

• Condensation: Poor insulation traps humid air indoors.

• Bathroom & Kitchen Steam: Daily moisture from showers and cooking accelerates mould formation.

  
  

Signs You May Need a Mould Inspection in Cascais

1. Musty smell that doesn’t go away.

2. Dark or discoloured patches on ceilings or corners.

3. Peeling paint or damp stains.

4. Health symptoms such as coughing, sneezing, or irritation that improve when you leave the room.

If you notice any of these, schedule a professional mould inspection Cascais homeowners trust.

How to Prevent Mould

• Control humidity: Use a dehumidifier during wet months.

• Ventilate: Open windows daily or install extractor fans.

• Fix leaks quickly: Don’t ignore slow drips or damp patches.

• Keep surfaces dry: Wipe down tiles and countertops after use.

• Improve insulation: Prevent condensation by insulating walls and ceilings.

Pro Tip: Cleaning visible mould won’t stop it from returning. You need to fix where the moisture is coming from.

Why Mould Shouldn’t Be Ignored

• Health concerns: Long-term exposure can trigger asthma and allergies.

• Structural damage: Mould weakens plaster, wood, and paint.

• Higher repair costs: The longer it’s left, the more extensive the repairs.

FREQUENTLY ASKED QUESTIONS

QUESTION: Why is mould so common in Cascais and coastal Portugal?

ANSWER: Coastal humidity, poor ventilation, single-skin concrete walls, and older waterproofing systems make homes in Cascais highly vulnerable to moisture buildup. Salt air also accelerates wall deterioration, allowing damp to penetrate.

QUESTION: What is the difference between mould and damp?

ANSWER: Damp is the moisture problem, while mould is the fungal growth caused by it. If you only clean mould but ignore the damp source, the mould returns every time.

QUESTION: How long does a professional mould inspection take?

ANSWER: Most inspections take 60–90 minutes, depending on the size of the home and how many rooms show signs of moisture or leaks.

QUESTION: Can thermal imaging really detect mould?

ANSWER: Thermal cameras do not detect mould directly but find the cold, damp areas where mould forms. This helps locate hidden leaks or trapped moisture inside walls.

QUESTION: What happens during a mould inspection by AllProperty?

ANSWER: We check humidity levels, scan walls with thermal imaging, test surfaces with moisture meters, check ventilation, assess leak risks, and provide a full report with recommendations.

QUESTION: Is mould worse in winter in Portugal?

ANSWER: Yes. Winter brings heavy rain, low ventilation, closed windows, and colder walls - all perfect conditions for mould growth in Portuguese homes.

QUESTION: Can mould spread through the house?

ANSWER: Absolutely. Spores travel through air, especially when humidity stays above 60%. If one room has mould, nearby rooms often follow unless the cause is fixed.

QUESTION: What makes AllProperty different from regular mould cleaning services?

ANSWER: We focus on diagnosis, not cosmetic cleaning. We identify the source - leaks, condensation, poor insulation, or rising damp - and help homeowners stop the problem
