When a network misbehaves, the switch, the Wi-Fi or the computer usually takes the blame. Sometimes the problem is the cable. These are the signs we look for.
1. Drops and slowdowns nobody can explain
If a desk or a room loses its connection intermittently and new equipment does not fix it, the cable run or its terminations may be damaged, too long, or poorly made. Testing the run tells you for certain.
2. The cable is older than your equipment by a decade or more
Check the jacket: the category is printed on it. Cat 5 (not 5e) and older cable was not designed for today's gigabit and multi-gigabit connections.
3. You are upgrading Wi-Fi
New Wi-Fi 6, 6E and 7 access points can push more traffic than an old cable run can carry, and many take their power over the cable too. An access-point upgrade is a good moment to run Cat 6a to each one.
4. The telecom room looks like a bowl of spaghetti
Unmanaged patch cords make every move, add or change slower and riskier. If no one wants to touch the rack for fear of unplugging the wrong thing, it is costing you time on every service call.
5. Nothing is labeled
If nobody can tell which port serves which office, troubleshooting starts with tracing wire. A properly installed system is labeled at both ends and documented.
6. The ceiling is full of cable nobody uses
Years of moves leave dead cable behind. Besides crowding the pathways, the National Electrical Code requires accessible abandoned cable to be removed, and it adds fuel load in the plenum.
7. You are renovating or moving
Walls and ceilings are open, and the floor plan is changing. It is the cheapest time you will ever have to put in new cabling, and the most expensive time to discover you should have.
Repair it or re-cable it?
Not every one of those signs means pulling new cable through the whole building. The first step is to test the runs you have: a certification test on the existing links tells you which column you are in before you commit to a scope. Ask any contractor whether testing the existing links is included in the walkthrough or priced separately.
| What you are seeing | Usually a repair | Usually a re-cable |
|---|---|---|
| One desk drops out, the rest are fine | Re-terminate or replace that one run | |
| Several runs failing on the same floor, and the jacket says Cat 5 or nothing at all | Re-cable that floor | |
| The rack is a mess but every link tests clean | Clean-up: new patch cords, labels, cable management | |
| Links fail certification across the board | Re-cable | |
| New Wi-Fi 6E or 7 access points on Cat 5e | Add Cat 6a runs to the access point locations only; keep the desk cabling | |
| A renovation is opening the ceilings anyway | Re-cable while they are open | |
| Dead cable crowding the plenum | Remove the abandoned cable; the live runs can stay |
A rough rule of thumb: once about a third of a floor's runs need work, it is worth getting a re-cabling bid for the whole floor alongside the repair bid, because the mobilization and the telecom-room work are the same either way and a re-cable leaves you with one documented system instead of a patchwork. Compare the two bids rather than assuming; the right answer depends on the building. What drives the cost per drop explains why the fixed part of the job matters so much.
What a re-cabling project looks like
We start with a walkthrough, count the drops and check the pathways and telecom rooms, then give you a written bid. The new system is installed, terminated, labeled and tested, and J&M's workmanship carries a 1-year parts-and-labor warranty. See our structured cabling services.
