Reviews

What customers say about Lee.

Straight from people whose radiators Lee has sorted, in their own words.

“I thought we needed a new boiler as this is what we had been told by other engineers… but when Lee arrived to take a look he made it very clear that there was another way to go about it. Such a refreshing approach not to be sold the more expensive item purely in the interest of profit. A power flush has worked a treat and we now have 8 working radiators instead of 3, and such a cosy house.”

FAQ

Common questions.

What actually is a powerflush?

A pump goes onto your heating and pushes water and cleaning chemicals round the pipes, radiators and boiler at high flow. It shifts the black sludge, rust and scale that settle at the bottom of radiators and clog the boiler.

What happens on the day?

We scan your radiators with a laser thermometer first, so we can see the cold patches. Then the cleaning chemicals go round and each radiator is flushed on its own until the thermometer shows no cold spots. Last, the system is dosed with inhibitor, rebalanced and tested again with the thermometer, and you get a report at the end.

How long does it take?

For an average three-bed home with 8 to 10 radiators, 6 to 8 hours on site. Bigger systems can take a full day or two.

Will it make my pipes leak?

Not healthy pipework. A powerflush uses high flow, not high pressure, typically under 1 bar, which is less than your boiler runs at.

Do I need one before a new boiler?

Most manufacturers want the system cleaned to BS 7593 before a new boiler goes in, or the warranty is at risk. A powerflush does that properly, so the new boiler is not pumping old sludge round from day one. More on flushing before a new boiler.

Is the survey really free?

Yes. We look at the system, check the radiators and give you a quote. There is no obligation to go ahead.
