How to Choose a Reliable Formaldehyde Removal Company in Singapore

Introduction

In recent years, more homeowners in Singapore have become aware of indoor air quality issues—especially after CNA’s 2024 report highlighted the long-term health risks of formaldehyde. Post-renovation formaldehyde removal is no longer just “nice to have” but increasingly seen as a necessary step before moving in. However, with the rise in demand, many service providers have entered the market, making it harder to tell which ones are trustworthy.

So how do you choose a formaldehyde removal company that’s truly safe, effective, and professional?

1. Check the Products They Use – Safety First

Not all “formaldehyde removal sprays” are created equal. Some products—such as chlorine dioxide, urea, and hydrazide-based agents—may show quick results but can be harmful to human health and cause secondary pollution. In fact, some of these chemicals can pose a greater health risk than formaldehyde itself.

Also, formaldehyde is slow-releasing and will continue to off-gas from materials like carpentry and adhesives for years. Short-term treatments that mask the smell will not solve the underlying problem.

✅ Only choose companies that use Lab-Certified, non-toxic and long-lasting products, such as photocatalyst coatings or enzyme-based solutions.

2. Look at Their Testing Equipment – Cheap Meters Lie

A proper removal company should use professional-grade formaldehyde meters—many of which cost over SGD $2,000. Cheaper versions found online often give inaccurate readings that can underestimate the actual level of pollution.

In addition, many providers conduct a test immediately after spraying, which is misleading. Right after chemical treatment, readings often drop temporarily. But formaldehyde continues to release slowly over time.

✅ Best practice: Test before treatment, and again 7–14 days later to measure actual results after re-release begins.

3. Beware of “Cleaning + Formaldehyde Removal” Bundled Services

Some cleaning companies now offer add-on formaldehyde services. This may seem convenient, but it’s problematic. Cleaning agents can interfere with coating adhesion and reduce product effectiveness.

For example, photocatalyst coatings typically require 5–7 days to fully cure and bond to the surfaces. If a company applies the treatment, then immediately wipes or mops the room, the coating may not work at all.

✅ Make sure cleaning is done before any coating is applied. After application, avoid disturbing the surfaces during the curing period.

4. Watch for Improper Testing Protocols

Did the company test with windows open? Then the reading is meaningless.

Proper formaldehyde testing requires:

• Windows and doors to be closed for at least 2 hours before testing

• Air-conditioners turned off

• Testing in each room separately, not just one point

✅ A credible provider will explain this clearly, and give you before-and-after reports from the same enclosed conditions.

Conclusion

Choosing a formaldehyde removal company in Singapore isn’t just about price—it’s about protecting your family and making sure your home is safe to live in. Be wary of shortcuts or packages that sound too good to be true. Ask the right questions, check for testing standards, and insist on product safety.

When in doubt, look for providers with proven experience, Lab-Certified materials, and transparent post-treatment testing.
