Standard insulation methods are often unsuitable for period properties, which is why we focus on breathable, non-invasive solutions. We typically utilise natural materials such as wood fibre or cork for internal wall insulation, which allow the building to breathe, naturally managing moisture and preventing the damp issues often associated with older walls. Our process begins with a professional, whole-house retrofit assessment. We carefully identify where heat loss occurs, ensuring our installation strategy respects the breathability of original stonework or timber frames.

Yes, through careful planning and the use of specialised techniques, your listed property can achieve significantly better energy performance. We navigate the complexities of listed building consent and conservation area rules for you, providing the technical evidence and compliance details required by local authorities in Caerphilly. By prioritising breathable insulation and traditional techniques, we help you eliminate cold spots and improve your EPC rating while maintaining the original look and feel of your building. Our approach ensures you avoid the condensation and thermal bridging risks that often plague traditional homes.

We know that the internal and external finish is just as important as the insulation itself. To provide a truly seamless service, we work closely with our sister company, Global Plastering. They offer traditional lime plastering and specialist finishing services, ensuring that once your insulation is installed, the aesthetic integrity of your walls remains perfectly intact. Whether you are dealing with uneven historic surfaces or requiring a specific period-appropriate texture, this end-to-end approach guarantees a beautiful, long-lasting finish that meets modern standards.
