The short answer is yes, you absolutely can! But, as with most renovations in HDB flats, there are some important rules you need to follow, especially if your BTO is brand new.
1) For Brand New BTO Flats
The 5-Year Lock-In Period
For new BTO flats, HDB has a crucial guideline: homeowners are not allowed to replace the full window set (this includes the frames and panels) for the first five years from the block’s completion date. So, if you were planning to hack out the existing windows and install a new set, you’ll have to wait.
But don’t worry, there is a solution to this.
The Best Solution For New BTOs: Secondary Glazing
Since you can’t remove the original windows, the most popular and HDB-compliant solution is secondary glazing.
What is it? It’s simply the installation of a second, separate window on the inside of your existing HDB window. Here’s why it’s a great option:
- It’s HDB-Compliant: You are not removing or altering the original window, so you don’t violate the 5-year rule. No special permit is usually required.
- Highly Effective: This method creates a large air gap between your original window and the new inner window. This gap is excellent at trapping sound waves, often providing better sound insulation than a single, double-glazed replacement window.
- Non-Destructive: The installation is done on your interior wall, leaving the original window untouched.
You can choose laminated glass for your secondary window to achieve maximum soundproofing results.
2) For BTO Flats After MOP (5 Years)
Once the 5-year MOP (Minimum Occupation Period) is over, you have the option to replace the entire window set. However, you must still follow HDB’s rules:
- Engage the Right People: You must hire a BCA-Approved Window Contractor who is also listed in the HDB Directory of Renovation Contractors.
- Maintain the Facade: The design and colour of your new window frames must match the original HDB windows. You cannot change the look of the building from the outside.
- Follow Safety Standards: The new windows must comply with all of HDB’s safety requirements, such as having safety stoppers for casement windows.

Conclusion
To put it simply:
- For BTOs under 5 years old: Your best and safest option is Secondary Glazing.
- For flats over 5 years old: You can opt for a Full Replacement, but you must use a BCA-approved contractor and adhere to HDB’s rules on appearance and safety.
A peaceful home is well within reach, even in a bustling city like Singapore. By understanding and working within HDB’s guidelines, you can effectively soundproof your BTO and enjoy the quiet you deserve.
