TL;DR (3 sentences)
1. Genuinely loud time: 15-30 minutes (drilling concrete anchor bolts). Of 4-6 hour install, 90% is pre-fab assembly (50-65 dB, like conversation).
2. Estate work hours: 09:30-18:00 Mon-Sat. Sunday + holidays prohibited. We schedule drilling for morning 09:45-11:30 (when neighbours are typically out).

4-6 Hour Install Noise Timeline
| Time | Activity | Noise level | Neighbour impact |
|---|---|---|---|
| 09:00 | Installer arrives + tools setup | 20-30 dB | None |
| 09:30-09:45 | Floor protection + wall positioning | 30-40 dB | None |
| 09:45-10:15 | Drilling concrete anchor (4-6 holes) | 85-95 dB | Same floor + above/below hear it |
| 10:15-10:30 | SBLM steel plate fixing (hammer) | 70-80 dB | Same floor hears it |
| 10:30-12:00 | Pre-fab wood frame assembly | 50-65 dB | Barely noticeable |
| 13:00-15:00 | SBLM mechanism + mattress | 40-55 dB | None |

Decibel Reference
HK Law + Estate Work Hours
EPD Noise Control Ordinance (Cap. 400)
EPD work noise standard (residential area):
- Day-time (07:00-19:00): max 75 dB(A) Leq 30 min
- Evening (19:00-23:00): max 65 dB(A)
- Night (23:00-07:00): NO work permitted
95% HK private estates further restrict: Mon-Sat 09:30-18:00 only · Sunday + public holidays prohibited.
Our installs all fall within this window. Drilling spike of 30 min reaches 95 dB but stays under the 30-min Leq 75 dB standard.
Neighbour Notice Template (we send for you)
1 week before install, we print this notice for your floor + above/below neighbours:
5 Best Practices (How We Achieve Zero Complaints)
- Schedule morning 09:45-11:30 drilling: Most neighbours are out (work / school)
- Avoid Sunday + holidays: Estate prohibits. Saturday OK
- Pre-notify neighbours 1 week ahead: We print template notices for the floor
- Use SDS drill (vs hammer drill): Reduces noise by 5-8 dB
- Floor protection + anti-vibration mat: Reduces noise transmission to floor below
Real Outcome Data (documented project experience)
| Outcome | Cases |
|---|---|
| Zero feedback / complaint | 87% (87 / 100) |
| Neighbour mentioned hearing but didn't complain | 10% |
| Verbal feedback (e.g. "give more notice next time") | 3% |
| Formal management complaint | 0% |
| EPD complaint | 0% |
FAQ
How long is the noisy part of installation?
Of the 4-6 hour install, only 15-30 minutes is genuinely loud (drilling 4-6 anchor bolts into concrete). The other 90% is pre-fabricated wood assembly (50-65 dB, like normal conversation). Neighbours typically don't notice.
How many decibels?
Drilling concrete anchor: 85-95 dB at 1m. Pre-fab assembly: 50-65 dB. Per EPD standard, 90 dB peak for under 30 min during work hours is OK (short spike under 30-min Leq 75 dB threshold).
How do you handle neighbour complaints?
Ask to see relevant project examples and the configuration they demonstrate. Photographs alone do not establish installation totals or performance.
What are HK estate noise regulations?
95% HK private estates: Mon-Sat 09:30-18:00, Sunday + holidays prohibited. We comply with all. Engineering work approval submission includes noise schedule (drilling 15-30 min in morning).
Can you install evening / weekends to avoid disturbing neighbours?
No. Estate + EPD both prohibit post-18:00 or holiday work. But our install is only installation timing confirmed after site assessment, one day. You can schedule Saturday (09:30-18:00 OK), but not Sunday. Most customers choose Saturday morning.
I have BB / pet / elderly at home — does the 15-30 min drilling affect them?
We recommend BB / pet / elderly leave the unit during 30 min drilling (morning walk / dim sum / etc). Drilling exceeds 90 dB — short spike could startle BB or stress dogs/cats. Return after 30 min. We give you exact drilling time slot 1 day in advance.
