The United Kingdom is globally renowned for its historically significant architecture and cultural heritage. Across England alone, there are over 370,000 entries for listed buildings on the National Heritage List. In Scotland it is over 47,000 listed buildings, over 8900 In Northern Ireland and in Wales, over 30,000 listed buildings.
However, maintaining historic buildings also presents unique challenges in the form of age-related wear, structural issues, and environmental factors, as well as the responsibility to preserve the historical characteristics of the structure. If not addressed using specialist care and expertise, these challenges can affect the preservation of the building and cause permanent damage.
Whether you are a home owner, commercial property owner, landlord or preservation society, understanding the measures needed to preserve the integrity of historic buildings is crucial to sustaining our country’s rich history.
Understanding the challenges of preserving historic buildings
The natural ageing process of older buildings can cause original materials to deteriorate and decay over time. Without specialist care, this can increase the risk of structural issues or even structural failure.
The old construction methods and drainage systems previously used mean that historic buildings may be more susceptible to damage from adverse environmental and weather conditions. Traditional buildings tended to be built using permeable materials such as brick, stone and lime-based mortars, making them more susceptible to moisture ingress. During winter, trapped water can freeze and fracture stone. Water can also trigger mortar decay, causing cracks and gaps in masonry or brick displacement. This can ultimately compromise the integrity of the walls within a property.
In addition, during periods of wetter weather rainwater ingress and excess moisture can lead to damp and condensation in the property. Without treatment, significant damp can cause structural damage, such as weakened foundations and wet or dry rot in structural timbers. Decayed timber in the roof structure may also lead to a sagging, collapsed roof.
Navigating the regulatory landscape that governs listed buildings can also be a challenge. The regulations vary in each region of the UK and therefore requires close work between various stakeholders such as local authorities, conservation officers and sometimes national heritage organisations to obtain approvals for maintenance and repair projects. If the work to a listed building has not received consent, this is a criminal offence and owners can be prosecuted. The lack of consent may also be found when the property changes hands and can stop a sale. If unauthorised work is discovered, it can be requested to be reversed by the current or new owners, at their cost.
It must be remembered that virtually any work on the inside, outside and within the curtilage of a listed building (constructed before 1st July 1948), may require listed building consent, including fitting a new kitchen or bathroom. It is always best to discuss proposed work with conservation officers before work begins. Some people believe that only what is mentioned in the official listing is protected. But that is simply not true.
Historic buildings are typically more prone to heat loss due to the cracks, gaps and draughts which develop as building materials distort over time, however, difficulties may be faced when ensuring that historic buildings can be adapted to accommodate modern energy efficiency measures.
Understanding the stringent regulations when retrofitting these properties for better energy performance, whilst preventing harm to their appearance and character is key.
Practical maintenance tips for historic buildings
With all of this in mind, maintaining and preserving historic buildings is no mean feat. While it can be a daunting task, many practical steps can be taken to ensure you are equipped to deal with the challenges posed by historic buildings.
The key to early prevention and intervention is regular inspection and maintenance of your property. Regularly inspecting vulnerable areas such as roofs, gutters and foundations to identify any early signs of wear and tear, clearing gutters and downpipes to prevent water ingress and repairing minor issues promptly can prevent them becoming major ones.
If you are undertaking conservation repairs, where possible use traditional materials and techniques that align with the building’s original design. In some cases, alternative, modern materials may be appropriate but be sure to consider whether they are compatible with the building’s existing structure and if they have been tried and tested on historic buildings. They will also require confirmation by the conservation officer or parochial church council and listed building consent.
Effective damp management in historic buildings requires an understanding of their age, the materials used in the construction and how these materials interact with moisture. When implementing damp proofing measures such as chemical damp proof courses or specialist waterproofing systems, discuss with the listing officer at the earliest opportunity to ensure they are suitable and do not lead to excessive moisture accumulation in old walls.
Chemical damp proofing may not be acceptable to the listing authorities and other alternatives will be used. Improving ventilation and using dehumidifiers may be an alternative way of reducing indoor moisture levels, whilst also maintaining healthy indoor air quality.
