Brickwork is designed to withstand the British weather for many years, but the mortar holding those bricks together won’t last forever. Over time, exposure to rain, frost, wind and changing temperatures can cause mortar joints to crack, crumble and deteriorate.
At JK Brickwork NW, we know how important well-maintained brickwork is to the appearance, strength and long-term protection of a property. One of the most effective ways to maintain it is through professional repointing.
But what exactly is repointing, and why is it so important?
What Is Repointing?
Repointing is the process of removing damaged or deteriorated mortar from between bricks and replacing it with fresh mortar.
Mortar joints play an essential role in protecting a building. They help bind the brickwork together while providing a barrier against the elements.
When mortar begins to deteriorate, it can leave the property increasingly exposed to moisture and further damage.
Professional repointing restores these joints, improving both the condition and appearance of the brickwork.
Signs Your Property May Need Repointing
Mortar deterioration can happen gradually, so homeowners don’t always notice the problem straight away.
Some common warning signs include:
- Crumbling or powdery mortar
- Visible cracks within mortar joints
- Gaps developing between bricks
- Mortar becoming recessed from the brick face
- Loose sections of mortar
- Damp patches appearing internally
- Water penetration around external walls
- Brickwork beginning to look tired or weathered
If you can easily scrape mortar away from the joints, it’s worth having the brickwork professionally assessed.
Repointing Helps Prevent Water Penetration
One of the biggest reasons to maintain your property’s mortar is to help keep moisture out.
Damaged mortar joints can provide routes for rainwater to enter external walls. Once moisture gets into the brickwork, it can contribute to damp problems and further deterioration.
Repointing seals vulnerable joints and helps restore the external protection of your property.
Protecting Your Brickwork from Frost Damage
Water penetration can become particularly problematic during colder weather.
Moisture entering cracks and gaps can freeze when temperatures drop. As water freezes, it expands, potentially placing additional pressure on surrounding bricks and mortar.
Repeated freeze-and-thaw cycles can gradually make existing deterioration worse.
Keeping mortar joints in good condition helps reduce the opportunity for water to enter in the first place.
Maintaining Structural Integrity
Mortar isn’t simply there to make brickwork look neat. It forms an important part of the masonry structure.
If mortar deterioration becomes widespread, sections of brickwork can eventually become less stable. Addressing deteriorating joints early can help preserve the strength and integrity of walls while potentially avoiding more extensive repairs later.
Improving Your Property’s Appearance
Freshly repointed brickwork can make a dramatic difference to the appearance of a property.
Old, cracked and uneven mortar can make even otherwise good brickwork look neglected. Repointing creates cleaner, more consistent joints and can restore character to older properties.
The correct mortar colour, composition and pointing style should be selected to complement the existing brickwork, particularly when working with traditional or period buildings.
Repointing Can Help Prevent More Expensive Repairs
Small areas of deteriorating mortar can quickly become larger problems if they’re continually exposed to the weather.
Ignoring damaged pointing could eventually contribute to damaged bricks, water penetration and more extensive masonry repairs.
Professional repointing is therefore an important form of preventative property maintenance. Tackling deterioration at the right time can help extend the lifespan of your brickwork and reduce the likelihood of larger repair bills.
How Is Brickwork Repointed?
Professional repointing involves more than simply placing new mortar over the existing joints.
The damaged mortar needs to be carefully removed to an appropriate depth before the joints are cleaned and prepared. Fresh mortar can then be applied and finished to create strong, consistent joints.
Correct preparation is crucial. Simply covering deteriorated mortar without properly removing the damaged material underneath is unlikely to provide the same lasting result.
Why Professional Repointing Matters
The correct mortar and technique can depend on the age, condition and type of property.
Using an unsuitable mortar mix can potentially cause problems, particularly on older buildings where traditional materials may have originally been used.
Experienced brickwork specialists can assess the existing masonry and determine the most appropriate approach for the property.
