Has the plumbing industry changed much in the last few decades?
If we're talking about technology, then obviously it has. But Charlie Mullins, founder of Pimlico Plumbers, believes the biggest transformation has been a reputational one.
In an interview with Bdaily Business News, the entrepreneur - whose company is now the biggest plumbing group in London - said that in his 35 years working in the sector he has seen some major changes.
He explained that back in the late 1970s and early 1980s when he started out the industry had a "shocking reputation of having more cowboys than a spaghetti western".
Plumbers were seen to be overcharging their customers for poor levels of service and treating people's homes like building sites, showing little consideration when it came to mess.
"So part of cleaning up the industry was literally making it less messy," Mr Mullins stated.
Now, plumbers take much more care when working in residential properties, whether than means putting down dust sheers, removing rubbish or simply taking off their dirty boots.
But it's not just about the mess. It's also about treating customers as customers and making sure they are fully informed and involved in the work that's taking place in their homes.
Mr Mullins said plumbers are now talking to customers about what they want and, more importantly, are not assuming that anyone who isn't a plumber is completely clueless.
All of this has contributed to a much better image for the plumbing industry and has resulted in greater confidence among consumers, he insisted.
It's perhaps one of the reasons why plumbers were recently voted among the most trustworthy tradespeople in a study carried out by Helly Hansen Workwear.
