Our approach to heritage retrofitting is rooted in the PAS 2035 framework, ensuring every installation is safe, efficient, and compliant. We focus on using high-quality, natural materials such as wood fibre and hemp boards. Unlike modern synthetic alternatives, these products allow your solid walls to breathe, managing condensation and preventing the damp issues often associated with older Victorian or Edwardian buildings. By working closely with local conservation standards, we ensure that thermal bridging is addressed while maintaining the aesthetic finish of your property.

When dealing with solid wall construction, using the wrong insulation can trap moisture, leading to internal mould and long-term damage to the masonry. Our breathable insulation systems are the ideal cold house solution for Treharris homeowners. These materials act as a thermal blanket, significantly reducing heat loss while allowing internal water vapour to escape. This is essential for improving your home's EPC rating and creating a consistent, comfortable temperature throughout the year, even during the coldest Welsh winters.

We take the stress out of home improvements by handling the complexities of building regulations and conservation requirements for you. As a PAS 2030 accredited company, our team is highly trained in whole-house retrofitting.
