There are a number of ways to bring a TV wire into a house. On a mature property, The Aerial Guys usually drill through an external wall with a 10mm drill, then run the aerial lead through a grommet on the internal wall and add sealant on the exterior. If you have wooden window frames, we can bring the aerial wire through the frame but, as the majority of properties now have uPVC frames, through the wall is normally the better option.
