Only if a fault already exists, such as an existing leak, corroded valves, radiators or poor pipework.
Depending on your location, we normally arrive at your home between 8 am and 10 am - unless otherwise agreed. The complete process is normally completed in 3 to 7 hours depending up on the size of your heating system.
Always using the most appropriate cleaning chemicals, for your system and pipework.
On completion we add an inhibitor to continue protecting your whole heating system.
