Older homes have stood the test of time, but they still need the right protection to continue performing well for decades to come.
Across Bolton, many traditional brick and stone properties suffer from moisture penetration, frost damage and deteriorating masonry. While it's tempting to seal external walls with waterproof paints or coatings, using the wrong products can actually trap moisture inside the building.
That's why breathable masonry protection has become one of the most effective ways to protect older homes without compromising how they were built.
🏡 Why Older Homes Need To Breathe
Traditional properties were designed very differently to modern homes.
Solid brick and stone walls naturally absorb small amounts of moisture before allowing it to evaporate back out again.
This natural movement of moisture helps keep the building healthy.
If non-breathable coatings are applied, moisture becomes trapped within the wall, increasing the risk of:
- Blown plaster
- Frost damage
- Spalling brickwork
- Damp internal walls
- Salt contamination
- Masonry deterioration
💧 What Is Breathable Masonry Protection?
Breathable masonry protection creates an invisible water-repellent barrier on brickwork, stone and mortar.
Rather than sealing moisture inside the wall, it:
✔ Repels driving rain
✔ Reduces water absorption
✔ Allows water vapour to escape
✔ Helps walls dry naturally
This protects the building while maintaining its ability to breathe.
🌧️ Protecting Against Penetrating Damp
One of the most common causes of damp in older homes is wind-driven rain.
When masonry repeatedly becomes saturated, moisture can eventually penetrate through external walls and appear internally as damp patches.
Applying a breathable masonry cream helps reduce water penetration while allowing trapped moisture to evaporate naturally.
❄️ Reducing Frost Damage
During winter, absorbed water can freeze inside brickwork.
As frozen water expands, it places pressure on the masonry, eventually causing:
- Surface flaking
- Cracked bricks
- Spalling faces
- Damaged pointing
Reducing water absorption helps minimise freeze-thaw damage over time.
🧱 Extending The Life Of Pointing
Mortar joints are often the first part of a wall to deteriorate.
Breathable masonry protection helps reduce the amount of rainwater entering exposed mortar, extending its lifespan and reducing future maintenance.
🌬️ Why Breathability Matters
The best protection doesn't simply keep water out.
It also allows internal moisture to escape.
This balance is particularly important in older solid wall properties where natural evaporation forms part of the building's design.
🔍 How We Assess External Walls
At Weather Wise Solutions Limited, we don't recommend external wall treatments for every property.
During our survey, we inspect:
- Brickwork condition
- Mortar joints
- Existing coatings
- Cracks
- External defects
- Penetrating damp
- Moisture movement
Only once we've identified the cause do we recommend the most appropriate solution.
🛠️ Why We Recommend ProPERLA Masonry Cream
Where appropriate, we recommend ProPERLA Masonry Cream, a high-performance breathable water repellent designed to protect brickwork and masonry without trapping moisture.
Benefits include:
- Reduced penetrating damp
- Long-lasting weather protection
- Breathable technology
- Lower maintenance
- Improved energy efficiency by helping walls remain drier

❓ Frequently Asked Questions
Will breathable masonry cream stop penetrating damp?
It can significantly reduce water absorption where sound masonry is allowing rainwater to penetrate. However, external defects such as cracked pointing or leaking gutters should always be repaired first.
Can older brickwork still breathe?
Yes. Breathable masonry protection allows water vapour to escape while repelling rainwater.
Is masonry cream suitable for listed buildings?
Many breathable treatments are suitable for traditional buildings, but every property should be assessed individually.
How long does masonry protection last?
High-quality breathable masonry creams can provide many years of protection when correctly applied.
