When we spoke with their team last month, they explained how their registered partners manage all statutory HDB submissions for casement setups. That takes a lot of stress off your shoulders during a renovation.
Plus, they provide both premium lines and budget-friendly options to match different wallet sizes.
Just keep in mind that you can’t simply walk in to view samples. Site visits are strictly by appointment only, so you must plan.

2. Sapphire Windows Pte Ltd
Website: https://sapphire.com.sg/
Address: 2 Loyang Drive
Contact: +65 6542 6616 / +65 8788 9616 / [email protected]
Hours: Monday-Friday, 9:00 AM – 5:30 PM
If you struggle with afternoon heat and traffic noise, Sapphire Windows manufactures local unplasticised polyvinyl chloride (uPVC) frames tailored for humid climates. Their durable material skips plasticisers to resist moisture and heavy temperature swings.
These uPVC profiles also deliver excellent acoustic insulation because the frame itself dampens sound alongside the glass pane. They even supply Red Dot Design Award-winning OTIIMA slimline aluminium systems with narrow 20 mm sightlines.
All these large glass panes are installed by their own in-house crew!
On the downside, their catalogue centres almost entirely on two frame systems. Homeowners seeking different frame materials will find fewer choices here.
Customer Reviews
Installation was well organised
The replacement window/door have made a whole world of difference and effectively shut out noise as well as dust coming from the outside. Installation was well organised and protective coverings supplied to reduce cleanup effort after completion. Recommended!

3. Ho Ho Engineering And Renovation Works
Website: https://www.hohodoorsingapore.com/
Address: 194 Pandan Lp
Contact: +65 6747 9019 / +65 9631 9288
Hours: Monday-Friday, 10:00 AM – 4:30 PM | Saturday, 10:00 AM – 2:00 PM
Operating since 1976, Ho Ho Engineering And Renovation Works has built a massive following across several generations of local homeowners. They fabricate their windows locally, allowing them to supply glass fixtures at direct factory rates.
With them, you’ll have the chance to choose from an impressive variety of designs, including casement, sliding, louvre, and vertical sliding units.
A close friend hired them for an older flat and praised how smoothly they handled the entire HDB permit process. They also assist private condo owners with Management Corporation Strata Title (MCST) guidelines.
However, they enforce strict panel-width limits on folding and casement units to protect the hinges. This cap might restrict your design if you have exceptionally wide structural openings.
4. Affordable Window Repair Singapore
Website: https://www.windowrepairsingapore.net/
Address: Tampines St. 21
Contact: +65 6432 8495 / [email protected]
Hours: Monday-Sunday, 8:00 AM – 10:00 PM
Urgent safety issues require quick action, and Affordable Window Repair Singapore stands out with emergency services running seven days a week. Their technicians can often repair damaged frames or cracked panels on the very day you reach out.
They handle complete residential window replacements and custom casement retrofits across flats and private properties.
When complete overhauls are unnecessary, they replace faulty latches, worn rollers, and corroded bolts with stainless-steel parts to meet safety guidelines.
For general home upkeep beyond window frames, you can also look into reliable handyman services.
The main trade-off is their repair-first policy for sliding setups. They only replace sliding systems when repairs are impossible, which may delay a full aesthetic overhaul.
5. Home Aluminium Metal Works
Website: https://homealuminiumsg.com/
Address: Singapore
Contact: +65 9003 6263 / [email protected]
Hours: Available 24/7
With more than 17 years in the industry since 2009, Home Aluminium Metal Works specialises in fast and dependable aluminium installations for local flats.
They make replacing old frames easier by completing standard 3-room and 4-room flats in just one full working day. They’ll even dismantle and dispose of your old frames at no extra charge.
On top of that, their itemised quotes come with no hidden fees, and there’s no Goods and Services Tax (GST) added to the bill. They’ll handle all mandatory Housing & Development Board (HDB) clearance paperwork before and after the job, too.
Once your new glass is in place, hiring the best window washers will keep everything sparkling.
The only downside is their strictly aluminium-only catalogue. Homeowners looking for composite or uPVC materials will need to look elsewhere.
