Repair Damage of Leak in Dunmow

How does it work?

We’ll find your leak guaranteed

We know from experience how a leak will create water damage to your property so understand how important it is to quickly locate and fix the leak.

Often the first indication that there is a leak is a low boiler pressure or a constant need to top up the boiler, giving very little clue as to the location of the leak. Traditionally leaks are detected using a labour-intensive process of digging up floorboards and knocking holes in walls and ceilings to find where in a pipe the leak is. This old, outdated process can make finding a leak difficult as well as causing hundreds of pounds of un-necessary additional damage.

Finding a leak is a bit like being a detective and we have a number of different tools in our armoury to help us:

Thermal Imaging:– A thermal imaging camera measures the surface temperature of a material to produce a coloured thermal picture of the area. Escaping water from leaking pipes will change the temperature in the materials that surround them. Thermal imaging cameras identify changes in temperature on the surface of different materials, highlighting the warmer and the colder surface areas helping to provide evidence of where the leak is originating from.

Acoustics Listening Equipment:– Water escaping from pipes makes sounds on different frequencies depending on the material the pipe is made from and the size of the leak. Acoustics allows us to ‘hear’ leaks. Partially good in areas where there is minimal thermal transference.

Moisture meters:– Leaking pipes create moisture and meters can be used to moisture map an area to give us a picture of where the leak is and the spread of the damage it has caused.

Tracer Gas:– In extreme cases (1%) we may use tracer gas, where gas is pumped into the pipework and a sniffer used to locate the area where gas is escaping from the pipe.

Salts Tests:– At times we need to identify where the source of water is coming from, for this we use Salts tests. A positive Chlorides results tells us it’s from a Main Water source.; positive for nitrates, tells us its rising damp coming up through the ground/soil; if both tests are negative, then its freshwater from rainfall or an in-ground spring

Your questions answered

Yes, once we locate the leak, we’ll give you a price to repair the pipe.

Our specialist technicians can not only find and fix leaks, but we also have the latest drying machine so we can quickly and effectively dry the damaged area and then get it repaired to your specifications. You don’t need multiple contractors; we’ll do it all for you.

This is the sure sign of a leak, possibly a small, slow one that had been ongoing for some time. Unfortunately, these are the hardest to find and cause the most damage due to the length of time and amount of moisture that has escaped into the building fabric.

This is the 64-dollar question. It depends on where the suspected leak is within your property, how complex it is to find and fix and how much damage the water has been caused, But don’t worry, once we’ve quoted, your price will be fixed.
