WHy is my boiler losing pressure?

If your boiler pressure is dropping, this may be the result of a hidden leak. To identify the source of the leak and fix the problem, Polygon uses non-destructive methods such as thermography. An in-depth thermographic survey of the property will highlight hot or cold spots which can then be used to pinpoint an area for further investigation. We may also conduct a moisture survey which will pick up signs of water damage and identify the escape of water.
