“If you think it’s expensive to hire a professional, wait until you hire an amateur.” This is a direct quote from a client that did not use the correct screening methods on a new hire. It was a plumbing job, and the way he told the story, even he couldn’t tell you why he risked it. Isn’t dirty water ruining everything the first thing that comes to mind?
In the end, while trying to save a buck or two he ended up paying way more in total. Plumbing is the kind of thing you would want a professional for. Some people even take these home improvement situations as an opportunity to learn, and while that is perfectly fine, it’s also about what you’re risking. Plumbing can go south really quickly, and turn into a downright out of control emergency. I wouldn’t suggest winging it there.
Some plumbing business will go above and beyond. The best plumbing company will wear shoe covers in to your home. I think it might just be that people assume the worst. As with vehicle repair, most people think there isn’t anything major wrong with your vehicle, that if you were a car mechanic it would be an easy fix, and that the shop you’re taking it to will just damage something else to keep you coming back. Sure, sometimes that could hold you back from hiring a professional but nowadays you can lookup user reviews, and those can shed light on previous customers’ bad experiences. It is safer than ever to hire a tried and true business.
In the end, it all comes down to your particular scenario. Weigh your options, consider what you’ve read here, and make your decision.
