Our technicians use purpose-built vehicles with specialized injection systems. We drill a precise pattern of small holes (approx. 22mm) into the exterior mortar joints and inject a bead insulation and adhesive mix. This ensures the cavity is evenly filled without cold spots. Once finished, the holes are sealed with matching mortar, leaving them virtually invisible.

No. To prevent damp, we perform a mandatory ventilation survey as part of the installation. We ensure your home meets current building regulations for airflow. Furthermore, our EPS beads are designed not to absorb water, which eliminates the risk of moisture "bridging" across the cavity to your internal walls.

Most homes built between 1920 and 1990 are ideal candidates. You can often tell by your brickwork: if the bricks are all laid lengthways (stretcher bond), you likely have a cavity. If your walls are at least 50mm wide and in good structural condition, you are likely eligible for a full installation.

Because the drilling creates minor vibrations, we recommend removing fragile ornaments or pictures from external walls. Our technicians will need brief access inside to check heating appliances and ventilation, but 95% of the work is performed entirely from the outside with minimal disruption.

Every installation is covered by a 15-35 year Guarantee. This comprehensive warranty covers both the premium materials used and the professional workmanship, giving you long-term peace of mind that your home's thermal barrier is fully protected.
