Lime mortar pointing
It is important to keep walls in good repair, particularly solid walls. Damaged lime mortar pointing can let damp through, causing deterioration to the building fabric.
Repointing in lime mortar may be needed if the original lime mortar has gradually degraded over time. This can be caused, for example, by leaking rainwater pipes or may simply be due to the age of the mortar.

The other common reason for needing to replace pointing is that the lime mortar has been replaced with inappropriate cement mortar.
Old stone buildings should always be pointed with lime mortar to allow them to breathe. This helps prevent damp problems and keeps the stone and mortar in good condition.
We are very experienced in pointing with lime mortar. Many conventional tradesmen prefer to use cement mortar because it is easier to use, but this can be very detrimental to your property. It can also be extremely difficult to remove, as it is so hard!
Lime Plastering
To ensure an old, solid-walled building can breathe, it is also important that lime plaster and breathable paint are used on the internal walls. If non-breathable plasters and paints are used, damp can’t pass through them, and you may be faced with the depressing sight of plaster and paint flaking off the wall.
If lime plasters are used, then a small amount of damp or condensation in your walls will not cause a problem, as the moisture can pass harmlessly into the air when conditions are right.
Lime plastering is quite an art, and is something we specialise in.
Lime Rendering
In many old buildings, the stone or brickwork was covered with a lime render, and often limewashed. Sometimes, unfortunately the old render has been replaced with a modern, cement based equivalent, causing breathability problems and damage to stone and brick work. There’s a common theme here, and if render is used on an old building, again it is vital that it allows the building to breathe, or problems are inevitable at some point.

Repointing in Lime Mortar: Why It Matters
What is Repointing in Lime Mortar?
Repointing in lime mortar is the process of renewing the mortar joints in masonry construction using lime-based mortar. This technique has been used for centuries to maintain and preserve buildings, especially those constructed before the widespread use of cement. Lime mortar is prized for its compatibility with historic bricks and stones, and for its unique properties that help buildings last for generations.
At Arcadian Restoration, we are specialists in lime mortar repointing, helping ensure your property remains structurally sound and visually appealing. When it comes to preserving the character and integrity of historic and traditional buildings, repointing in lime mortar is a crucial service. Unlike modern cement mortars, lime mortar is flexible and breathable, allowing moisture to evaporate naturally from the masonry. This reduces the risk of trapped damp, which can cause structural damage over time.
Repointing in lime mortar is not just about repairing or refreshing the look of your property. It is about safeguarding the building’s structure and health. Over time, mortar can deteriorate due to weathering, environmental factors, or inappropriate repairs with hard cement mortars.
When mortar breaks down, it can allow water to seep into the walls, causing further decay and potentially expensive damage. By repointing with lime mortar, you are choosing a solution that respects the original construction while providing needed protection.
The Benefits of Repointing with Lime Mortar
- Choosing to repair or maintain your masonry with lime mortar offers a range of important benefits that support both the longevity and authenticity of your property. Some of the most significant advantages include Breathability: Lime mortar allows masonry to “breathe,” preventing moisture buildup and decay.
- Because lime mortar allows masonry to breathe, it helps prevent common issues such as rising damp and salt deposits, which can lead to crumbling bricks and stones. This property is especially important for older buildings without modern damp-proof membranes. Flexibility: It accommodates the natural movement of buildings, reducing the risk of cracks and damage.
- With its ability to accommodate movement, lime mortar minimises stress on the building’s fabric. This can help prolong the life of both the mortar and the masonry units themselves, preventing the need for more extensive repairs in the future. Aesthetic Authenticity: Lime mortar matches the original appearance of period properties, maintaining their historic value.
- Lime mortar can be tinted and finished to match the existing mortar of your property, ensuring a seamless blend with original materials. This attention to detail is crucial for listed or conservation properties, where maintaining historic accuracy is often a legal requirement. Eco-Friendly: Lime is a sustainable material that absorbs carbon dioxide during curing.
Lime is a low-impact material, and using it in construction supports traditional skills and sustainable building practices. The environmental benefits also include improved energy efficiency for your property, as lime mortar can help regulate indoor humidity and temperature.
Our Approach to Lime Mortar Repointing
Our Process
Every property is unique, which is why our lime mortar repointing service begins with a thorough assessment. We evaluate the existing masonry, the type of brick or stone, and the condition of the mortar. Our team then selects the most appropriate lime mortar mix, often using local sands to ensure a perfect colour and texture match.
Once the preparation is complete, we carefully remove the old or damaged mortar by hand to avoid damaging the surrounding masonry. The new lime mortar is then applied in layers and finished to match the original joint style. Our skilled approach results in a repair that is both durable and visually sympathetic to your building’s heritage.
At Arcadian Restoration, our specialists use traditional techniques and carefully selected lime mortars to ensure the best results. We remove damaged or unsuitable mortar by hand, taking care to protect the surrounding brick or stonework. Our team then repoints using a suitable lime mortar mix, matched to the original materials and finish of your property.
Frequently Asked Questions About Repointing in Lime Mortar
How do I know if my building needs repointing?
Signs include crumbling or missing mortar, damp patches on interior walls, or visible gaps between bricks or stones. You may also notice areas where cement mortar has cracked or failed, which is particularly common in older buildings that were originally constructed with lime mortar.
Is lime mortar suitable for all types of masonry?
Lime mortar is ideal for most traditional brick and stonework, especially in historic or listed buildings. For modern masonry, an assessment will determine whether lime mortar or an alternative is best.
How long does lime mortar take to cure?
Unlike cement, lime mortar cures gradually through carbonation—a process where it absorbs carbon dioxide from the air. This can take several weeks, so we take care to protect the mortar from rapid drying or frost during the curing period.
What aftercare does lime repointing require?
After repointing, we recommend gentle cleaning and monitoring of the joints. Avoid harsh chemicals or pressure washing, which can damage the mortar.
