Moisture damage to walls and skirting can be caused by a number issues. It could be a water leak to your central heating system, hot/cold water service pipes or a waste/soil pipe. In older properties it could be rising damp.
Many insurers do cover Trace & Access (T&A). Firstly check your policy documents. T&A cover is a separate risk so will be listed as part of your buildings cover. If you are unsure call your insurer and ask.
If a pressurised system loses pressure you have a leak somewhere. Your system should hold pressure indefinitely & certainly between boiler services. Water is escaping from the system and may be damaging your property.
This is not unusual. The sound of a leak resonates along the pipework and through whatever material the pipe touches. Pinpointing a leak needs specialist electronic acoustic equipment.
Tracer gas is completely safe and harmless. The gas is 5% hydrogen and 95% nitrogen. It is odourless, non-toxic and inert. Hydrogen does not naturally occur in the atmosphere. We use a special "sniffer" to detect the leaking gas.
First check that the ballcock valve is not faulty. Note the timing between drips, tie the ballcock arm in the closed position for a couple of hours then untie it. If the drips are more frequent or the filler runs you have a leak.
Firstly, make sure that there is no known water consumption in your property. Check washing machines, dishwashers etc. Wait 30 minutes after flushing a toilet, sometime they take an age to finish filling. Find your boundary or meter box. Watch the fine movement cog or arm. This is very sensitive, even a dripping tap will make it move. Video your meter for 3 to 5 minutes and compare the starting and ending position of the fine movement cog/arm or the "100ml" clock (see picture). Any movement indicates water consumption or a leak. Turning off your internal stopcock and watching the meter again will tell you if the leak is internal or external - if there is still movement with the internal stopcock closed the leak is external.
A salts test is used to determine whether the source of the moisture in construction materials is from the ground or is "treated" water. The small container in the photo is the test for ground water. It will be RED if nitrates are present, nitrates come from the ground therefore the moisture has spent time in the ground and picked up the nitrates. This is "rising damp".
The larger contain is testing for chlorides. Chlorides are present in treated water that comes from your utility company's water supply (mains water). If the solution is YELLOW then chlorides are present, therefore the water has come from a water system supplied by mains water i.e. central heating system, hot or cold water supply or a waste/soil pipe.
The photo shows no nitrates and no chlorides so the test is "inconclusive". This usually means that the moisture is from pure uncontaminated water. This is possibly rain water or flood/run-off water that has not come from a mains supply in been in contact with the ground for any length of time.
This indicates that there is water soaking through your ceiling. You may not have a "wet room" (room supplied with water) directly above the stain however, water tracks along pipes, joists, beams and above plasterboard. We have endoscopes (small cameras) to access ceiling voids to trace the leak.
IF YOU HAVE WATER RUNNING THROUGH A LIGHT FITTING DO NOT USE THE LIGHTS UNTIL CHECKED BY AN ELECTRICIAN.
IF THE CEILING IS TEXTURED ("ARTEX") IT MAY CONTAIN ASBESTOS - DO NOT DISTURB IT.
