How much would it cost to repoint these historical buildings

Repointing isn’t just for your average home; imagine if we could bring historical buildings back to life! We’ve done the maths and taken a look at how much it would cost to restore some of the world’s most historical buildings. From restoring the pyramids to a medieval makeover of Manchester Cathedral, here’s how much it would cost to repoint some of the world’s most iconic buildings.

These are just general estimates for a bit of fun and shouldn’t be taken too seriously. The actual costs of repointing such iconic buildings would be far more complicated, involving everything from materials to logistics, and of course, a whole lot of history!

So, while we’ve used Right Point’s pricing methodology to give you a rough idea, there’s no doubt the real costs would involve more than a few zeros! 😉

1. The Pyramids of Giza: Ancient Wonders in Need of Modern Care

Historical Background:
Built around 4,500 years ago, the Great Pyramid of Giza is one of the Seven Wonders of the Ancient World. Constructed using massive limestone blocks, its exterior was once encased in polished white limestone, giving it a smooth and gleaming surface that has largely worn away. The brickwork, made of large limestone blocks, would require specific care to preserve both the pyramid’s historical accuracy and structural integrity.

Repointing Costs:
While we’re all too aware that this colossal structure is more than a few metres of mortar away from a quick repointing job, we’ll calculate the cost based on modern-day pricing. With a surface area of over 50,000 square metres for the base, assuming a cost of £25-£30 per square metre for cement mortar, and perhaps double that for lime mortar, we’re looking at a theoretical total of around £1.5 million—though the actual cost would be far higher due to the complexity of the task! The Pyramids have endured a lot of weathering, graffiti and wear from tourists which would significantly age the look of the Pyramids.

Historical Construction Methods:
The pyramid’s original mortar would have been made from a mix of sand, water, and lime, and later versions of mortar were created using a more advanced mix of gypsum and clay to bond the massive limestone blocks.

2. The John Rylands Library (Manchester)

Historical Background:
Completed in 1900, the John Rylands Library in Manchester is a stunning example of Victorian Gothic architecture. Built with a combination of sandstone and brick, its intricate stonework and pointed arches are a true testament to the craftsmanship of the time.

Repointing Costs:
While the John Rylands Library is not nearly as large as the Great Pyramid, the complex brickwork of this building would require careful restoration. Using lime mortar would likely be the best option here to maintain the integrity of the historical fabric. With an estimated 10,000 square metres of brickwork, you could be looking at a cost of £400,000 - £500,000.

Historical Construction Methods:
The building’s brickwork features traditional Victorian Gothic construction techniques, with high attention to decorative details and the use of decorative stonework. The mortar was a lime-based mix to match the natural ageing of the building materials.

3. Leigh Town Hall (Leigh, Greater Manchester)

Historical Background:
Leigh Town Hall, designed by local architect James Caldwell Prestwich, was completed in 1907. The building is a fine example of Edwardian Baroque architecture, constructed from Darley Dale sandstone and Westmorland green slate.
Prestwich, born in nearby Atherton and educated at Leigh Grammar School, returned to leave a lasting architectural legacy in his hometown. The ground floor along the Market Street elevation originally housed a row of nine shops, adding a practical dimension to the civic structure.

Repointing Costs:
To repoint Leigh Town Hall’s sandstone exterior and preserve its historical charm, lime mortar would be essential to maintain its historic integrity. With an estimated 3,000 square metres of stonework, the cost could range between £120,000 and £150,000, depending on the complexity of the decorative features.

Historical Construction Methods:
At the time of its construction, the use of Darley Dale sandstone was a deliberate choice for its durability and elegance. Westmorland green slate is used on the roof for practicality but to also make for a visually striking appearance. The original mortar mix would have been lime-based, allowing the building to breathe and adapt to the natural weathering over time.

Recent Renovations:
Between 2019 and 2021, Leigh Town Hall underwent a major £1.3 million restoration funded by the National Lottery Heritage Fund and Wigan Council. An extensive archive in the basement now houses 800 years of local history, making it a vital resource for the community. The addition of a public archive search room and a conservation studio for digitising records ensures that the history of Leigh is more accessible than ever.

A Nostalgic Touch:
For us at Right Point, Leigh Town Hall isn’t just a landmark—it’s part of our heritage. I remember growing up playing outside the front of Leigh Town Hall, those warm summer, Sunday evenings when the town would be quiet.

4. Manchester Cathedral (Manchester)

Historical Background:
Manchester Cathedral, originally built in 1421, stands as a remarkable example of medieval architecture in the heart of the city. Constructed predominantly from local sandstone, its intricate stonework tells a story of craftsmanship and resilience. The cathedral has withstood centuries of weathering, urban development, and even bombing during World War II, making its preservation a vital part of Manchester’s heritage.

Repointing Costs:
Repointing a building of this historical importance would be a meticulous task, requiring lime mortar to maintain the structure’s integrity and authenticity. With an estimated 5,000 square metres of stonework, the cost for repointing could range from £200,000 to £250,000, depending on the level of detail required for the intricate carvings and weathered sections.

Historical Construction Methods:
The cathedral’s sandstone blocks were quarried locally, showcasing the natural materials of the area. Builders in the 15th century used lime mortar to bind the stones, which allowed the structure to breathe and adapt to the environment over time. This traditional construction method is why using modern cement-based mortar during restoration would risk damaging the delicate stonework. Lime mortar, with its flexibility and permeability, remains the best choice for maintaining the building’s historical integrity.

Can you repoint a listed building?

Yes, listed buildings can be repointed. Although it’s not as easy as just booking us for a local callout. Typically you’d have to obtain listed building consent from the local planning authority before carrying out any work. There’s a lot to consider when repointing a listed building, as pointing can significantly change the look and character of a building.

Key points to remember when repointing a building:

1. Choose the Right Mortar
   Not all mortar is created equal. For older or listed buildings, a traditional lime-based mortar is an absolute must. It allows the building to "breathe" by letting moisture escape, which prevents damage to the bricks or stonework. Matching the colour and texture to the existing mortar is just as important for a seamless finish.
2. Bring in the Experts
   Repointing isn’t just slapping on new mortar—it’s a skilled craft. Work with a qualified conservation specialist or a contractor experienced in heritage restoration (like us!) to get it right. A poorly done job can cause long-term damage and stick out like a sore thumb.
3. Assess the Existing Mortar
   Take a good look at what’s already there. Analysing the existing mortar’s composition helps ensure the new mix will be compatible. Using the wrong mortar can weaken the structure or accelerate decay.
4. Check with Your Local Planning Authority
   If you’re working on a listed or protected building, don’t skip this step. Your local planning authority needs to know about your plans. Some projects require consent, and it’s better to be safe than sorry when dealing with building regulations.
5. Prioritise Quality Materials
   This isn’t the time to cut corners. Invest in high-quality lime mortar and other materials that will stand the test of time. It’s worth it to preserve the character and structural integrity of the building.
6. Don’t Forget the Details
   Heritage buildings often have unique features—decorative brickwork, intricate stone carvings, or even inscriptions. Repointing these requires a steady hand and attention to detail, so make sure your contractor has the experience to handle it.
7. Think About the Weather
   Timing matters. Repointing should ideally be done in mild, dry weather to give the new mortar the best chance to cure properly. Extreme heat, frost, or heavy rain can affect the quality of the work.

By keeping these points in mind, you’ll not only protect the building’s history but ensure it remains standing tall for generations to come. At Right Point, we’ve got the expertise to handle every detail, so your restoration is done right the first time.
