Selangor Electrical Inspection Service – Professional House Wiring & DB Box Upgrade for New Homes
Recently, we received a call from Mrs. Anna, a new homeowner who just bought her house in early 2025. She had heard worrying stories from her neighbour about power tripping whenever there was a thunderstorm. The neighbour’s foreign wireman kept saying it was just “lightning problem” and nothing could be fixed. Naturally, Mrs. Anna started to feel uneasy about her own home’s wiring, especially since she had also used a similar contractor recommended by the same neighbour.
Before moving in, she wanted peace of mind. That’s when she decided to request a whole house wiring inspection.
Why It Was Difficult to Find a Good Electrician
Mrs. Anna tried contacting several electrical companies, but most of them were not interested in providing inspection services. The reason is simple. Since the whole house was already wired, many contractors felt there was “no profit margin” in just doing an inspection.
Besides, a proper wiring check takes time, requires many different tools, and needs experienced technicians who know what to look for. Most contractors don’t want to spend the effort on this type of work, so they just reject the job.
Luckily, one of her colleagues recommended us, Mr Electrician, and she quickly got in touch with Alex from our team.

Why a Simple Test Pen Can’t Detect All Wiring Problems
We scheduled the appointment on Tuesday and arrived with our full set of inspection tools. Unlike what many homeowners believe, a simple test pen cannot detect all wiring issues. Every part of the electrical system needs proper testing equipment, from identifying broken wires, checking for short circuits, to verifying power point connections.
Mrs. Anna’s husband was surprised and impressed when he saw how well equipped we were. His previous contractor had told him that “a test pen is enough to check everything.” But as we showed him, proper tools and experienced technicians are essential for a safe and reliable inspection.
What We Found – Hidden Wiring Problems
Once we started, it didn’t take long before we discovered several hidden issues:
- Messy wiring above the ceiling – wires joined randomly and covered up to avoid detection.
- Different wire types and colours mixed together – a dangerous and unprofessional practice.
- Loose connections at power points – which could easily cause overheating or fire.
- DB box not properly fixed – compromising the overall safety of the system.
It was clear that the original contractor had rushed the job and tried to hide poor workmanship.

The Solution – Repair and Rewiring
After explaining the problems to Mrs. Anna and her husband, they agreed that some sections of the house needed to be rewired for safety. We carefully replaced faulty wiring, secured all loose connections, and properly fixed the DB box.
The process took time, but by the end of the job, the electrical system was safe, neat, and reliable. Most importantly, Mrs. Anna and her family could now move into their new home with confidence, knowing their wiring had been inspected and corrected by licensed electricians.
Electrical Safety First: The Importance of House Wiring Inspection
This case is a good reminder for all new homeowners:
- Don’t assume new wiring means safe wiring.
- Always have a qualified electrician perform a full electrical inspection.
- Using the right tools and experience makes all the difference.
- It’s always cheaper and easier to fix before the house is fully renovated and furnished.
At Mr Electrician, we believe prevention is better than cure. A thorough inspection today can save you from costly repairs – or even accidents – in the future.
