Owning a historic building in Edinburgh is a privilege and a responsibility. The city's Georgian New Town and medieval Old Town together form a UNESCO World Heritage Site, and the listed sandstone tenements, townhouses and commercial buildings that line its streets need ongoing care to stay in good condition. This guide walks property owners through the key stages of heritage building restoration, what to expect, and how to choose the right specialist.
Edinburgh's buildings are mostly constructed from blonde or red sandstone quarried locally in the 18th and 19th centuries. Sandstone is porous and has a hardened outer skin that protects the softer stone beneath. Standard pressure washing or aggressive abrasive blasting can strip this protective skin, opening the stone up to accelerated weathering and structural decay.
Heritage building restoration is therefore as much about what you don't do as what you do. The right specialist will choose the least invasive method that achieves a high-quality result.
Property owners typically come to us with one or more of the following problems:
Many Edinburgh buildings still carry a layer of black sooty crusting from the coal-burning era. This isn't just unsightly; it traps moisture and accelerates stone decay. Removing it reveals the original colour of the sandstone, often surprising owners with how warm and golden the stone really is.
Through the 20th century, many sandstone buildings were painted with modern impermeable masonry paints. These paints trap moisture inside the stone, causing it to spall and crack from within. Removing them is essential but must be done with care to avoid damaging the substrate. Our paint removal services use soda blasting and DOFF cleaning to lift paint without harming the stone.
Moss, algae, lichen and ivy can root into the stone surface, holding moisture against the building and accelerating decay. North-facing elevations and areas shaded by trees suffer most.
Edinburgh's high-footfall city-centre buildings are regular targets. Removing graffiti from sandstone requires specialist techniques to avoid leaving ghost marks or damaging the case-hardened surface.
A typical heritage restoration project follows this sequence:
Depending on the building's size, a full external restoration can take anywhere from two weeks to several months.
If your property is listed (Category A, B or C) or sits in a conservation area, you will likely need consent before any cleaning or paint removal can take place. The City of Edinburgh Council expects detailed method statements that demonstrate the proposed work won't harm the historic fabric.
We work regularly with architects, surveyors and conservation officers and can supply all the documentation needed. Our experience with stone cleaning Scotland projects across Edinburgh, Fife and beyond means we know what local authorities expect.
Not every cleaning company is qualified to work on heritage buildings. When choosing a contractor, look for:
You can see examples of our work on historic Scottish buildings on our projects page, including Kinpurnie Castle, the Commando Memorial and Dunblane Cathedral.
Every building is different, but as a guide:
Scaffolding is usually the biggest variable and often the largest single line on the quotation.
