Unsealed gaps around doors, window frames, and floorboards allow precious heat to escape, forcing your heating system to work overtime. In many period properties across Caerdydd / Cardiff, such as Victorian or Edwardian homes with original sash windows, these drafts are a major contributor to thermal bridging. By addressing these weak points, we significantly reduce heat loss and help improve your home's EPC rating. Whether you are a landlord needing to meet current MEES compliance standards or a homeowner looking to lower carbon emissions, effective draught proofing is a vital step in upgrading your building's thermal performance.

We do not believe in a one-size-fits-all solution. As PAS 2030 accredited experts, we follow rigorous PAS 2035 retrofit standards to ensure that your home's ventilation remains balanced after our work is complete. Excessive sealing without proper airflow can lead to condensation and damp issues, which is why we assess your property as a whole system. Our team carefully identifies where unwanted air infiltration occurs and applies high-quality, long-lasting materials to seal your home effectively. This thorough process ensures that you achieve maximum energy efficiency without compromising the air quality or integrity of your property.

Sometimes, effective draught proofing requires more than just seals; it may involve minor structural adjustments or internal finishes. Because we work closely with our sister company, Global Plastering, we offer a complete, end-to-end service for our clients. If your project requires remedial plastering or surface repairs following the installation of insulation or draught-proofing materials, we handle every detail under one roof. This coordination saves you the hassle of hiring multiple contractors and ensures a high-quality finish that meets our strict standards of craftsmanship.
