"The best fix is the one you never need. That's why I spend more time explaining systems to homeowners than most installers spend fixing problems. Understanding your home's infrastructure isn't just practical — it's the foundation of responsible ownership."
— Pieter van den Berg
Pieter grew up in Utrecht watching his father work as a building contractor. That early exposure shaped everything. While other kids were playing football, he was learning how pipes fit together and why electrical systems need respect. It wasn't glamorous work, but it was real.
After completing his Installatiemechanica certification at ROC Utrecht in 2008, he spent over a decade working on residential projects across the city. We're talking thousands of jobs — from simple tap replacements to complete system overhauls. He earned his VCA Safety Certification along the way because shortcuts aren't an option when you're working in people's homes.
What sets Pieter apart? He actually explains things. Most installers finish a job and leave. He takes time to walk homeowners through what they've got, why it matters, and what to watch for. That approach eventually led him to technical writing in 2018. If people deserve to understand their plumbing and electrical systems, they deserve clear, honest information about them.
