Our team is fully PAS 2030 compliant and provides PAS 2035 retrofit assessment and coordination, ensuring that every measure taken is suitable for your specific build.

By adhering to these rigorous standards, we ensure your home remains healthy, dry, and compliant with local planning authority requirements.

Frequently Asked Questions About Listed Building Insulation

Can I insulate my listed building without planning permission? Often, internal wall insulation can be installed without altering the external appearance, though we always recommend checking with your local planning authority. Our team can guide you through the consent process if external works are required. Will insulation cause damp issues? Traditional buildings need to breathe; we use specialist, moisture-permeable materials that prevent condensation while trapping heat. How do I get started? We begin with a professional retrofit assessment to identify the best strategy for your specific wall type and property condition.

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.
