A house, not a Swiss cheese
As Eichler do not have crawl space or attic, owners who needed to add phone and TV capacity had only one choice: to run the wires along the outside walls. After 30-40 years you can imagine why most Eichlers look like a Swiss cheese entangled in a web of cables…
One of the immediate reward of using structured cabling is that you don’t need anymore all these ugly cables that were running along the house. I took great pleasure in tearing them!
It makes a huge difference aesthetically (check out most Eichler homes - they are plagued with this mess of wires running outside), but it also closes the door to the hordes of ants, spiders and termites that were using these convenient access into your home. Granted, they will find other access but there is no reason to make it too easy on them!
