A wet carpet beside a radiator naturally directs attention to the nearest valve, yet a dry fitting does not settle the source. Water can arrive from pipework below, another room, a wall route or a non-heating cause. Leak detection in Sandhurst is more effective when the moisture boundary and heating conditions are documented before furniture or flooring is moved.
Map the moisture without spreading it
Photograph the whole wall and floor junction, then mark the outer damp edge on a sketch rather than on the carpet itself. Note whether the underlay, skirting or wall also feels affected. Avoid lifting fitted carpet when gripper rods, cables or weakened flooring may be hidden beneath.
Use clean absorbent paper at several labelled points to compare dampness, but do not press electrical meters or improvised probes into the floor. Record the room temperature, whether the heating was running and the time the area was first noticed.
Check the radiator as one possibility, not the conclusion
Inspect visible valves, bleed point and exposed pipe entries from a safe position while components are cool. Look for dried deposits, corrosion or a trail, and photograph rather than tighten. A leak below the floor may leave no water on the valve body, while condensation or a nearby wall leak can wet the same carpet edge.
Write down recent bleeding, decorating, flooring work or repeated boiler top-ups. Compare the patch after ordinary heating cycles; do not force the system to run or raise its pressure to provoke evidence.
Prepare a bounded investigation
Provide the moisture map, heating timeline and any pressure record to the professional handling leak detection in Sandhurst. The next step may be a plumbing check, heating-circuit assessment or building-fabric inspection. The evidence should determine which system is tested first.
Stop using the room if the floor becomes soft, water spreads rapidly or sockets are affected. Keep children and pets away from loose carpet. After repair, retain the original boundary sketch and photograph the same points during drying; a remaining stain is not automatically fresh leakage, while an expanding wet edge requires prompt review.
Protect the evidence during drying
Do not aim a portable heater directly at the patch or cover it with plastic to make it look unchanged. If a dehumidifier is used on professional advice, record its position and operating times because altered conditions affect later comparisons.
Keep damaged underlay, carpet samples or removed fittings until the responsible party says they are no longer needed. Label photographs before and after lifting. This creates a clear distinction between what was observed naturally and what became visible only during access.
