5 Best Window Companies in Singapore (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 8 min read

An HDB resale flat with worn-out louvre windows, or a new BTO waiting on window and grille installation, both run into the same question: which window company in Singapore actually shows up on time and does clean work. The five companies below carry a combined total of over 5,200 Google reviews, and the busiest name has logged more than three times the reviews of the smallest, a real gap in scale worth knowing before you request quotes.

Short answer: For window installation, repair and film in Singapore, Zenith Window Films leads by a wide margin (4.9 stars, 2,773 reviews), specialising in heat and glare-reducing window film. For structural window replacement and grilles, Hands@Windows Servicing holds the top rating among installers at 4.9 stars and is HDB and BCA approved.

How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the company’s live Google star average. Review volume is how many customers have rated them, ranked against other Singapore window companies. Confidence weighs the rating by that volume, so a 4.9 from over 2,700 people carries more weight than a 4.9 from a few hundred. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much do windows cost in Singapore? (2026)

Costs vary significantly between window film, which is priced per panel or square footage, and full aluminium window and grille replacement, which is priced by unit size and material. BTO group-buy deals can reduce per-unit costs for new flat owners. Ask each company for a scoped quote based on your specific unit.

Across Singapore

The companies above serve HDB flats and private homes across Singapore, from Sin Ming and Admiralty to Woodlands and Kaki Bukit. Searching for a window company near me? Every listing shows a live phone number and website so you can request a quote.

What to ask before you hire a window company

Is your company HDB and BCA approved if I need compliance work for a flat sale?
Is the quote for window film, or full frame and glass replacement?
How long from measurement to completed installation?
Will you handle permit approval, or is that on me?
What warranty applies to the windows, grilles, or film installed?

Frequently asked questions

How did you choose these window companies?

We started from window installation, repair and film companies in Singapore with a public Google presence, then ranked by rating, review volume, consistency and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Do I need an HDB-approved contractor for window work?

Yes, if you are selling an HDB flat, window work often needs to meet Form B1 compliance requirements from an HDB and BCA approved contractor. Confirm this status before hiring for that purpose.

What is the difference between window film and window replacement?

Window film is applied to existing glass to reduce heat and glare, a faster and cheaper option, while full window replacement involves new frames and glass and is a larger project.

The bottom line

Zenith Window Films is the clear choice for heat and glare film given its scale and consistency, while Hands@Windows Servicing is the safest pick for HDB and BCA-approved repair work. For full-house replacement, At Aluminium and Ziam Gei Huat both stand out on speed and communication.
