At Kilat Kilat, we’ve handled our fair share of tough cleaning jobs. But nothing prepared us for the massive challenge that came with cleaning a 25,000 sq ft x 4-storey mansion in Klang. This blog is our way of sharing the real, behind-the-scenes experience of what goes into post-renovation deep cleaning on such a massive scale — the kind of job that truly tests your patience, your teamwork, and your passion for spotless results.
Here’s what really happened — from breakdowns to 3 AM shifts and scaffolding nightmares.
Week 1–2: A Rocky Start — Construction Chaos and Cleaning Clashes
We kicked off strong, sending up to 20 – 25 cleaning staff every single day. Everyone was hyped. Supervisors we appointed for the job , workers each are assigned with their individual part and assignment as a break town team. We thought its gonna be an easy ride based on the actual condition of the house.
But the excitement didn’t last.
What we didn’t expect was the ongoing renovation works still happening even after we started cleaning. Contractors were drilling, sawing, painting — basically undoing our work every day. We cleaned one area, only to see it dirty again hours later. Frustration levels skyrocketed. We say hundred of people are lingering around different area of the house and doing their part of work be it ceiling , painting contractor, cabinet designer, flooring polisher you name it. They are all around.
Our supervisor, Kak Lin, was caught between our team, the main contractor, and the owner’s demands. The stress became so overwhelming that one afternoon, she just couldn’t hold back her tears. Everyone tried to console her as everyone is in this difficult situation too. That moment reminded us: this wasn’t just a cleaning job, it was emotional labor too.
Moving Mountains (and People): Daily Ops Behind the Scenes
With such a big job, logistics were a daily puzzle. We arranged a van to ferry our team in batches, making sure each shift arrived and left on time. It wasn’t just about showing up — we needed our people energized, on-task, and ready to clean under very demanding conditions. There were days that cars broke down or delayed, it is not easy to get 25 people to a spot on the same time.
We also faced pressure to scale up. For exterior window cleaning, we were required to set up a massive scaffolding system on the 4-storey glass facade, while using a skylift for higher, more dangerous areas.
Safety checks, coordination with subcontractors, and even weather came into play. One slip could be costly — and unfortunately, it was.
Week 3–4: Setbacks, Sleepless Nights & One Costly Mistake
Midway through the project, we were forced to remove our internal scaffolding overnight due to a sudden demand by the scaffolding contractor. They wanted the space clear by 9 AM the next morning.
That meant only one thing: we had to start our final glass cleaning shift at 3 AM.
Yes, our team actually came in before dawn, worked under dim lights, and cleaned their hearts out just to meet the deadline. That was one of the proudest moments of the whole project. No complaints, just grit.
In another incident another day put a big slap on our budget
One of our staff accidentally dropped a tool from height, which cracked a section of the plaster ceiling. It was a genuine accident, but the contractor billed us a hefty repair fee and insisted we cover the cost. We took responsibility and paid — it’s part of being a professional and accountable cleaning company.
The Final Stretch: 1 Month and 7 Days Later
After over five weeks of intense daily work, constant coordination, last-minute demands, emotional pressure, and more than a few painful lessons, we completed the project.
The mansion? Sparkling. From marble floors to massive glass windows to every corner of the balustrade and balcony — our team made sure every inch shone.
We didn’t just leave the site clean. We left with stories, scars, and most importantly — the pride of knowing we handled one of the biggest residential cleaning projects in Klang.
Why This Story Matters
Post-renovation cleaning isn’t just about brooms and vacuums. It’s about coordination, communication, and commitment — especially when you’re dealing with large homes or mega projects.
If you’re planning a big home renovation or just got your dream house built, don’t underestimate post-construction cleaning. Hiring a team with experience in high-pressure, high-value cleaning jobs can make the difference between a chaotic handover and a perfect move-in day.
FAQ About Large-Scale Cleaning Projects
Q: How long does a cleaning job like this normally take?
A: For standard homes, it can take a few hours to a couple of days. But for massive projects like this 4-storey mansion, it took over 1 month and 7 days to complete thoroughly.
Q: What if other contractors are still working on-site during cleaning?
A: It’s best to coordinate your cleaning schedule after all major works are completed. If that’s not possible, expect to clean some areas more than once. Be flexible — or better yet, hire a team like Kilat Kilat that knows how to adapt.
Q: Can Kilat Kilat handle special equipment like scaffolding or skylift?
A: Yes! We’re equipped to handle both internal scaffolding and external skylift operations, especially for high glass facades and complex structures.
Q: Do you take responsibility if something goes wrong?
A: Yes, we believe in accountability and professionalism. While accidents can happen, we always strive to resolve them transparently — just like we did when we covered the ceiling repair.
