Maintaining airtightness in a building is essential for enhancing energy efficiency, thermal comfort, and indoor air quality. To ensure airtightness over time, meticulously seal the building envelope using flexible caulks and sealants, and improve window and door seals with draught-proofing strips. Properly sealing HVAC duct penetrations and insulating wall and ceiling breaches also contribute to reducing air leakage. Regular maintenance inspections, along with professional consultations, can help balance airtightness with effective ventilation, preventing the build-up of indoor pollutants and ensuring a healthier living environment.

When you build a new home, one of the key things you’ll need is something called an Energy Performance Certificate, or EPC. We help with this from start to finish, starting with SAP calculations, which are like a test on how well your home will use fuel and power. Once your build is complete, we check everything again and make sure your EPC gets logged properly. A good rating means lower bills and a cosier home, which is great for you or anyone looking to buy later. We’re here to help make the whole process simple and stress-free.
