Borescope cavity inspection in Welling

For properties in Welling, a borescope inspection starts with a clear price and ends with a written record of what was found and done. A borescope inspection pushes a small camera through a hole about the size of a pencil into the cavity to see whether it is empty, partly filled or filled, what the fill is and whether there is debris.
