From Zero to Hero: Nail Damage Repair – Electric Floor Heating Fix

When a radiant floor heating system suddenly stopped working, a full flooring replacement seemed inevitable. But thanks to skilled diagnostics and WarmlyYours field support, one PRO turned a hidden installation mistake into a fully restored floor—without ripping everything out.

The Challenge: Short Circuit and a Melting Wire

The homeowner reported a cold floor and an unresponsive system. When our technician arrived on site, the issue quickly escalated: after opening the thermostat box, a short on the white wire was discovered. Even more concerning—when a variac was connected to test further, the power wire nearly melted.

The original installer had already opened the wall to examine the power supply leads, but everything behind the wall was in working order. That pointed to one likely source: damage beneath the flooring itself.

The Investigation: A Hidden Threat at the Threshold

The next step was to lift the edge of the carpet in the threshold area between the tiled and carpeted rooms. Underneath, the technician found wood shims—used to smooth the flooring transition—secured in place with six nails.

Using an ohmmeter, the technician tested the area. The results were clear: four of the nails were in contact with the heating element, confirming that the mat had been punctured and was shorting out.

The Fix: Repair the damaged areas, one at a time.

With the damage isolated, the repair was straightforward—but precise:

• The tile was removed from the affected area and the thinset was cleared
• The damaged heating element was liberated and each damaged spot was cut open
• A repair was done to each spot
• Full resistance tests were performed
• Two tiles were replaced in this location

The heating system came back online immediately—without replacing the mat or damaging the floor. What could have been an expensive reinstallation became a textbook save.

The Result: A Fast Repair, a Warm Floor, and One Happy Homeowner

The floor was restored the same day, and the homeowner was thrilled. More importantly, the PRO was empowered to resolve the issue on-site with confidence—thanks to WarmlyYours support and a properly equipped toolkit.
