The 5 Best Window Installers in Singapore for Better Home Comfort
Upgrading your home fittings is exciting, but finding the best window installers in Singapore can feel overwhelming with all the local building regulations. Windows keep out the rain, cut down street noise, and keep your family safe.
Poor installation can lead to leaks, high electricity bills, and costly legal penalties if parts fail. While minor latches might be solved by a handyman, full replacements demand certified specialists.
We researched and tested the top installers in the city to help you pick the right team for your property.

Established in 2010, Top 1 Singapore Safety Window brings over 15 years of hands-on experience to local residential and commercial projects.
They operate as an HDB and BCA-compliant installer, which takes the stress out of handling regulated window replacements.
You also get direct factory pricing without any middleman markups inflating your renovation bill.
When we talked to one of their reps about safety grilles, they clearly explained their pet-safe and invisible grille choices. They also provide a standard turnaround of 7 to 10 days for professional installation.
But keep in mind that this 7- to 10-day wait time means they aren’t set up for same-day emergency replacements.
2. Home Aluminium Metal Works

Contact: +65 9003 6263 | [email protected]
Schedule: Available 24/7
Home Aluminium Metal Works is a BCA-approved and HDB-licensed contractor that focuses heavily on public housing projects.
They manage all window production completely in-house, handling everything from cutting raw aluminium to polishing before setting up your panels.
Their team works on 3- to 5-room flats, resale properties, and Home Improvement Programme (HIP) upgrade jobs.
We really appreciate this team’s full replacements that include complete dismantling and disposal of your old frames. This initiative saves you from booking separate junk removal services.
It’s a bonus that their customer support is reachable around the clock for consultations.
On the downside, their service scope focuses on residential properties, so they don’t take on large commercial glass installations.

3. WSS Windows & Doors Pte Ltd

Website: https://wss.com.sg/
Address: 11 Senoko Drive
Contact: +65 8758 3131 | [email protected]
Schedule: Monday-Friday, 8:30 AM – 5:30 PM | Saturday, 8:30 AM – 12:30 PM
Operating out of a 22,000 square foot facility in Senoko, WSS Windows & Doors builds and installs everything in-house with zero middlemen. They hold HDB, BCA, ISO 9001, and bizSAFE Star credentials that give peace of mind to their clients.
They apply the same structural durability used in airport and major infrastructure projects to everyday Build-To-Order (BTO) flats and condominiums.
When we had them install replacement panels for my family home, their technicians carried out a thorough 10-point safety check. That covered rollers, alignment, and leak testing before leaving.
They also handle mandatory HDB paperwork on your behalf.
Just note that their Senoko location closes early on Saturdays and stays closed on Sundays, so weekend site visits are tight.
Customer Reviews
Early installation with excellent service
We spoken to the staff Chloe, who provided excellent customer service and was very attentive to our needs. We requested an early installation date, and they delivered on that request. The quality of the workmanship and the overall service were truly outstanding.This is highly recommended. From Eddie/MusLee

4. A&V Aluminium Contractor

Website: https://www.anvaluminium.com/
Address: 71 Woodlands Avenue 10 Unit 07-14
Contact: +65 9068 6501 | +65 8157 6772 | [email protected]
Schedule: Monday-Saturday, 9:00 AM – 5:00 PM
Homeowners dealing with street noise will appreciate A&V Aluminium Contractor for their specialised soundproof window systems and pet-proof grilles.
They offer standard sliding and casement setups, as well as combined designs that integrate louvres and top-hung vents.
This team provides a comprehensive window evaluation along with a free on-site assessment before giving you a quote. A technician inspects your wall openings and discusses potential installation hurdles directly with you.
However, booking that on-site visit is a mandatory requirement before you can receive an exact price quote. Plus, their classic soundproof window configuration opens inwards, which requires you to keep surrounding indoor ledge space clear.
Customer Reviews
Responsive after-sales window support
My windows were installed by Alex and HJ five years ago, and I recently had an excellent experience with their after-sales service. When one of the handles came off, I reached out to them and they responded on the very same day. They promptly arranged for someone to replace the handle free of charge. What impressed me even more was their professionalism — they also took the initiative to inspect the rest of the windows without us even asking. It’s rare to find such responsive and responsible service these days. Highly recommended!

Meticulous site visit and installation
Amazing work carried out by Alex and his team! Alex is meticulous. He did site visits to ensure that the window measurements are correct, communicated with us to find out our needs before proposing the suitable kinds of windows that would best fit our lifestyles. The entire process was a breeze for us due to Alex’s professionalism. We love the newly installed windows at our new home! Highly recommended Alex and his team 👍

5. Ziam Gei Huat Aluminium Pte Ltd

Website: https://zghaluminium.com/
Address: 39 Woodlands Close, MEGA@Woodlands #03-40
Contact: +65 6264 3088 | [email protected]
Schedule: Monday-Friday, 9:00 AM – 6:00 PM | Saturday, 9:00 AM – 5:00 PM
With 19 years of industry experience, Ziam Gei Huat Aluminium, a direct factory supplier, manufactures custom window systems tailored to exact site measurements. Direct factory supply can help keep prices lower by removing third-party retail markups.
They’re the sole maker of an exclusive swing-and-slide system, which slides sideways and rotates 180 degrees so you can clean exterior glass panes from indoors.
If you frequently book window washers for exterior panes, their rotating setup makes routine upkeep far simpler. Their installation teams cover BTO flats, private estates, and commercial spaces.
The only real trade-off is that their catalog focuses almost entirely on aluminium window frames rather than multi-material alternatives.
Customer Reviews
