Does Your House Need Repointing? Here’s How to Tell

If you own an older property in Bath or the surrounding areas, there’s a good chance your home’s brickwork or stonework will eventually need repointing. Mortar naturally wears down over time due to weather exposure, moisture, frost and general ageing. Left untreated, damaged pointing can lead to much bigger structural and damp problems.

At Robinsons Building & Roofing, we regularly help homeowners identify early signs of mortar deterioration before it becomes a costly issue. Whether you’re searching for experienced builders in Bath or reliable roofers in Bath, understanding when repointing is needed can help protect your property for years to come.

What Is Repointing?

Repointing is the process of removing damaged or crumbling mortar from between bricks or stone and replacing it with fresh mortar. While the bricks themselves may still be in good condition, the mortar joints are often the first part of a wall to fail.

Good pointing acts as a weatherproof barrier, helping to keep moisture out and maintain the structural integrity of your home.

In areas like Bath, where many properties are built using traditional stone and older construction methods, proper repointing is especially important to preserve both appearance and durability.

Signs Your House May Need Repointing

1. Crumbling or Missing Mortar

One of the clearest signs is visible gaps or crumbling mortar between bricks or stonework. If you can scrape mortar away easily with a key or your finger, it has likely deteriorated beyond its useful life.

Missing mortar allows water to penetrate walls, which can lead to damp issues and frost damage during colder months.

2. Damp Patches Inside Your Home

Damaged pointing can allow rainwater to seep into external walls. This often appears internally as damp patches, peeling paint, mould or musty smells.

Many homeowners assume roof leaks are the only cause of damp, but faulty mortar joints are another common culprit. Experienced roofers in Bath and builders alike will often inspect both roofing and brickwork when investigating moisture problems.

3. Cracks Around Brickwork

Cracking in mortar joints may indicate movement or weather-related deterioration. Small hairline cracks can quickly worsen if water enters and freezes during winter.

If you notice stair-step cracks or widening gaps, it’s best to have the issue professionally assessed before it affects structural stability.

4. Loose Bricks or Stonework

When mortar fails completely, bricks or stones can become loose. This creates both a structural concern and a safety hazard, especially around chimneys, garden walls or higher areas of the property.

Loose masonry should always be repaired promptly to prevent further damage.

5. Weathered Appearance

Sometimes the signs are more visual than structural. If your brickwork looks heavily worn, patchy or uneven, repointing can restore the appearance of your property while also improving protection against the elements.

For period homes in Bath, sympathetic repointing using the correct mortar mix is essential to maintain the character of the building.

Why Repointing Matters

Ignoring deteriorating mortar can lead to several costly problems over time, including:

• Damp and mould growth
• Internal wall damage
• Reduced insulation efficiency
• Structural movement
• Frost damage to bricks and stone
• Chimney instability

Repointing is far more affordable than replacing damaged brickwork or dealing with major structural repairs later down the line.

How Often Does a House Need Repointing?

There’s no single answer, as it depends on the age of the property, exposure to weather and the quality of previous workmanship. However, mortar joints typically last anywhere from 25 to 50 years.

Homes exposed to strong winds and heavy rain may require attention sooner, particularly around chimneys and rooflines.

If you’re unsure, a visual inspection from experienced builders in Bath can help determine whether repairs are needed.

Can Repointing Be Done in Winter?

Repointing is best carried out during milder, drier weather conditions. Extremely cold temperatures can affect how mortar cures, while heavy rain can wash out fresh pointing before it sets properly.

Spring through early autumn is usually the ideal time for repointing projects in the UK.
