Why Bad Cabling Costs You for Years

Most network and AV problems trace back to the same place. Behind the walls. In the ceiling. Behind the rack. The cabling that nobody wants to think about, that nobody asks questions about during the proposal, and that nobody notices until something stops working.

We have spent twenty years cleaning up other people’s cabling. Sometimes the cleanup is just a few bad terminations. Sometimes it is years of small problems that all started with one shortcut. Either way, it costs more to fix than it would have cost to do right.

Here is what bad cabling actually causes, and what you should be looking for if you suspect your current setup is one of those years-of-small-problems situations.

Slow Networks

Your network speed is only as good as your weakest link. That includes the cable. A run of Cat5 in a building that should have Cat6A is going to bottleneck your entire network, no matter how fast your internet connection is or how new your switches are.

The same goes for fiber. Old fiber that was great when it was installed might not support the speeds modern equipment requires. We have seen offices spend money on new servers and network gear only to find out the bottleneck was the cabling installed fifteen years ago.

Random AV Problems

Audio that drops out. Video that flickers. Conference room cameras that lose signal in the middle of a meeting. All of these can be cabling issues. Loose terminations. Cables run too close to power lines. Cables damaged by being pulled too hard during install. Cables that were never tested before the contractor left.

The frustrating thing about these problems is they are intermittent. The system works most of the time. The issue only shows up at the worst possible moments. By the time the IT person or AV technician shows up to look, everything is working again.

Bad cabling causes the kind of problems that nobody can ever quite pin down.

Hard to Troubleshoot

A clean structured cabling install is labeled. Every cable. Every patch panel port. Every termination. When something breaks, anyone who walks in can identify the cable, trace it back to the source, and fix it.

A bad install is a tangled mess. No labels. Cables that disappear into ceilings without documentation. Patch panels where someone has to plug and unplug each connection one at a time to figure out which port goes where.

The labor cost of troubleshooting a bad cabling install can easily exceed the cost of redoing it correctly. We have done both. The cleanup is almost always more expensive than the right install would have been the first time.

Impossible to Scale

Adding desks to an office. Expanding a conference room. Putting in a new camera. Installing a new wireless access point. All of these depend on having capacity in your cabling infrastructure.

A bad install does not have capacity. Every new requirement means pulling new cable. Opening walls. Adding overhead runs. Working around the original mess instead of building on top of it.

A good structured cabling install plans for capacity. Extra runs left in place. Patch panels with room to grow. Conduit installed during construction that future cables can be pulled through without opening walls. This is the part that determines whether your building grows with your business or fights you every step of the way.

How to Tell If You Have a Cabling Problem

A few questions to ask. Do you have intermittent network or AV issues that nobody can quite explain? When something breaks, does it take hours to diagnose because nothing is labeled or documented? Have you been told you cannot add capacity without major work? Is there a tangle of cables behind your rack that nobody wants to touch? Did the original contractor disappear, leaving you with no documentation of the install?

Any of those answers being yes is a sign worth investigating.

Cabling is the foundation everything else sits on. Done right, it disappears. Done wrong, it never stops causing problems. If you suspect your cabling is one of those years-of-small-problems situations, we are happy to come take a look and tell you straight whether it is worth cleaning up or starting fresh.
