Radiant Floor Leak Detection in British Columbia
Precise location of leaks in in-floor radiant heating systems without damaging finished flooring across BC homes and buildings.
Professional Radiant Floor Leak Detection Across BC
At LeakInspection.ca, we have developed specific protocols for radiant floor leak detection that address the unique characteristics of these systems. The process begins with a system assessment: we check the system pressure log, review the layout of the tubing loops, and identify which zone is losing pressure. Using thermal imaging, we scan the floor surface during a heat cycle — the warm water escaping from the leak creates a distinct hot spot on the floor that our high-resolution cameras capture, even through tile, hardwood, or engineered flooring. For systems where the leak is too small to create a clear thermal signature, we isolate the individual loop and perform a tracer gas test, injecting a hydrogen-nitrogen mixture and scanning the floor surface with a sensitive gas sniffer.
Our technicians understand the construction of the most common radiant floor systems found in BC: PEX tubing encased in lightweight gypcrete or concrete slabs (common in Vancouver condos and townhomes), staple-up systems in joist cavities (common in BC houses), and Uponor Wirsbo systems with the characteristic oxygen barrier layer. We are also experienced with electric radiant floor systems, though these present different failure modes. Our reports include precise leak location documentation, the system layout with the affected loop identified, and repair recommendations — typically involving either a localized access point for loop repair or loop abandonment with surface routing of a replacement line. We coordinate with your heating contractor to ensure the repair approach is compatible with the system design.
How Radiant Floor Leak Detection Works
System pressure and temperature log review to confirm active leak and affected loop
Thermal imaging scan of the floor during a heat cycle to identify leak hot spots
Individual loop isolation and tracer gas testing for small or intermittent leaks
Leak point marking and report preparation with access recommendations
Frequently Asked Questions
Can you find a radiant floor leak without damaging my finished floor?
Yes. Our primary detection method is thermal imaging, which can identify the warm water escaping from the leak through virtually any flooring material — tile, stone, hardwood, laminate, or carpet. In most cases, we locate the leak without removing any flooring. Only the repair access requires minimal floor removal, and we pinpoint it precisely.
What causes radiant floor leaks in BC homes?
Common causes include nail or screw punctures during flooring installation or subsequent renovations, manufacturing defects in PEX tubing (particularly in systems installed between 1998 and 2008 with certain production batches), chemical attack from floor leveling compounds that degrade the oxygen barrier, and stress fractures at manifold connections from building settlement.
How do you repair a radiant floor leak once located?
The repair approach depends on the system type and the leak location. For accessible leaks in joist cavities, the tubing can be cut and coupled. For slab-embedded leaks, the typical approach is to expose the tube at the leak point, install a repair coupling, and patch the slab. If the leak is in a location where access is extremely difficult, the affected loop may be abandoned and a replacement loop surface-routed.
Can radiant floor leaks cause mould problems?
Yes. A slow leak in a radiant floor system saturates the subfloor, underlayment, and flooring materials, creating an ideal environment for mould growth. The warmth of the system accelerates mould proliferation. If you suspect a radiant floor leak, prompt detection is essential to prevent extensive mould remediation and flooring replacement.
