Damp Proofing Solutions for Period Property

Damp Proofing Solutions for Period Property

Period properties, with their unique charm and character often suffer from damp issues. These issue are exacerbated by modern building techniques like cement-based mortars, renders paints and injection damp proofing.

These modern methods can choke the breathability of traditional buildings, trapping moisture and leading to damper, colder walls that deteriorate much faster than dry warm walls. At Moffatt Stoneworks, we specialise in the health of period properties. We understand that damp is as harmful to buildings as it is to its occupants.


Damp walls that can’t breathe will not only cause dangerous and unsightly mould inside the property but will promote accelerated damage to the wall itself. For example dry breathable stonework won’t freeze in sub 0 temperatures but damp areas behind painted stoneworks that can’t breathe will. As the wall freezes it begins to break apart and crumble. And will continue to do so until the paint is removed.
Trust us to apply our expertise in preserving the heritage of your home.

When evaluating older properties for damp problems, it’s essential to inspect both visible and concealed areas. Watch for indicators such as peeling paint, mold development, and deteriorating stonework—significant signs that moisture has breached. Focus on the state of windowsills, basements, and exterior walls, as these areas are frequently prone to dampness.

Take a look below at the main points for you to consider when undertaking an work on listed buildings. Understand and Respect Regulations Listed buildings are protected by strict regulations (e.g., the Planning [Listed Buildings and Conservation Areas] Act 1990). Any intervention must be authorised and should not permanently alter the building’s character. Accurately Diagnose the Damp Issue Identify the source of moisture—whether rising damp, penetrating damp, or condensation. A thorough investigation (including moisture mapping and surveys) is essential before any remedial works are planned. 3 Choose Sympathetic, Reversible Treatments Use techniques that can be removed or reversed without causing damage. For example, modern damp proof membranes or cavity drain systems are designed to be minimally invasive and reversible, preserving the historic fabric. Maintain Breathability of Building Materials Historic structures were built with "breathable" materials (such as lime mortars, stone, and brick). Remedial measures should not seal up the building, as trapping moisture can exacerbate decay. Engage Specialist Expertise Work with contractors and surveyors who have specific experience with historic or listed buildings. Their expertise ensures that the chosen solution is both effective and sympathetic to the building’s heritage. Plan a Comprehensive Conservation Strategy Damp proofing should be part of a wider programme of maintenance and conservation. This means addressing related issues (like inadequate ventilation or external water management) to prevent recurrence. Document and Monitor Interventions Keep detailed records of all diagnostic findings, interventions, and materials used. Regular monitoring after treatment will help identify any future issues early, ensuring the long-term preservation of the building. Consult with Conservation Officers Liaise with local heritage bodies or conservation officers to ensure that any proposed works meet both technical and heritage requirements, thereby avoiding any potential conflicts with preservation policies. Balance Preservation with Practical Performance While the primary goal is to protect and preserve historic fabric, the practical aspects of ensuring a dry, healthy, and safe building environment must also be met. Expertise from both conservation and building performance fields is key.
