Why Traditional Properties Require Expert Retrofitting

Historic buildings, such as the beautiful Victorian and Edwardian homes found throughout Newport, often suffer from thermal bridging and significant heat loss due to their original solid wall construction. Unlike modern builds, these homes need specialised care to avoid moisture buildup and structural damage when insulation is introduced. Our PAS 2035 accredited team ensures that every intervention is moisture-breathable and appropriate for the building fabric. By opting for a professional heritage retrofit, you can reduce your carbon footprint and slash high energy bills without compromising the aesthetic character that makes your property special.

Our Approach to PAS 2035 Compliant Heritage Retrofit

We follow a rigorous, whole-house approach guided by PAS 2035 standards to ensure your property remains safe and compliant. Our process begins with a detailed assessment to identify the best materials and methods for your specific wall type, whether you require internal wall insulation or loft and roof upgrades. As a SWIGA-backed contractor, we provide industry-leading insurance-backed guarantees for your peace of mind. Our team works closely with you to navigate any planning permissions or local authority requirements, ensuring a seamless experience from start to finish.

Seamless Finishing with Global Plastering

One of the biggest concerns for owners of listed buildings is the quality of the internal finish after insulation is installed. We solve this through our partnership with our sister company, Global Plastering. While we handle the technical installation and thermal upgrades, their team ensures the final plastering work is completed to the highest traditional standard. This end-to-end service guarantees that your home is not only warmer and more energy-efficient but also retains its authentic interior character and beauty.

How can you improve an EPC rating in a listed building?

Many landlords and homeowners in Caerllion and Caerleon struggle to meet MEES requirements for rental properties due to the limitations of historic structures. We help you navigate these challenges by identifying compliant, non-invasive insulation methods that improve your EPC rating without needing drastic structural alterations. Whether you are dealing with a cold, damp Victorian property or an old stone-built cottage, our, professional, PAS 2030 compliant team provides the advice and installation expertise needed to bring your building up to modern standards. Reach out to our local experts today at 01443 809770 to book your comprehensive retrofit assessment.

Heritage Property FAQs

Frequently Asked Questions

Answers to common questions about breathable historic building insulation, thermal bridging solutions, and PAS 2035 compliance across South Wales and South West England and South Wales.

Do I need planning permission to insulate my listed building in Ferndale?

+

Yes, in most cases, you will need Listed Building Consent for internal or external wall insulation. Because these works change the thickness of the walls or the materials used, local planning officers want to see that the heritage of the building is being protected. We can help provide the technical details needed for your application.

Why shouldn't I use cheap foam insulation on an old stone wall?

+

Old buildings were designed to be "breathable." Moisture travels through the stones and mortar and evaporates. If you put non-breathable foam against the wall, you trap that moisture. This leads to "interstitial condensation," which rots floor joists and causes damp patches. We use breathable wood fibre or mineral wool to keep your walls healthy.

Will I lose the original features like my coving or skirting boards?

+

We do everything we can to preserve the character of your home. Sometimes this involves carefully removing and reinstating skirting boards or using thinner, high-performance insulation in areas with intricate decorative features. Our partnership with Global Plastering allows us to replicate traditional finishes so your home looks exactly as it should—only warmer.

How long does it take to insulate a period property?

+

Every building is unique, but a typical internal wall insulation project for a terraced house usually takes between one and two weeks. This includes the preparation, the insulation fixings, and the specialist lime plastering finish.
