The cost of getting it wrong

What contamination costs you

A surface can look clean and still carry the particles, microbes or moisture that cause batch rejection, failed audits, higher bacterial counts, poor indoor air quality and food safety risk. In controlled environments, visual cleanliness is not proof of control. SGH helps you measure it, control it and prove it.

Evidence, not appearance

We combine physical barriers, surface treatments and environmental monitoring so that hygiene in your critical areas is measured and documented, not assumed.

CC Matting

Stop contamination at the entrance

Reusable contamination-control matting for critical entry points. It captures foot- and wheel-borne particles at the door, before they ever reach your cleanroom or production floor, and it's cleaned by mopping and squeegee drying instead of being peeled off and thrown away.

  • Retains up to 99.9% of foot- and wheel-borne particles (per CC Matting information; performance depends on location, traffic and cleaning regime)
  • Up to 80% of contamination enters controlled environments at floor level, mainly through foot and wheel traffic
  • Expected lifespan about 4 to 5 years, fully recyclable
  • 100+ successful installations

Same corridor, controlled entry

The corridor above shows the same entry point before and after CC Matting was fitted at a hygiene-sensitive site. The mat sits flush at the threshold and is maintained in place, rather than replaced sheet by sheet.

Antimicrobial nano-coating

A surface treatment that keeps working between cleans

What it is: A non-toxic, alcohol-free antibacterial and antiviral surface treatment. It forms a protective layer that kills and decomposes bacteria, viruses and airborne mould spores on contact, tested and proven to last up to 6 months after a single application.

Who needs it: Hospitals, schools, hotels, offices and any high-traffic surface where you want protection between cleans, not just during them.

1

Assess

Assess the surface material and application environment.

2

Prepare

Clean and prepare the surface.

3

Apply

Apply the coating.

4

Verify

Verify the treated surface.

5

Maintain

Recommend a maintenance and reapplication schedule (actual service life depends on the surface, environment, cleaning frequency and chemical exposure).

What you get: Broad-spectrum antimicrobial and antiviral protection, deodorising and anti-allergen benefits, and fewer conditions for mould and fungus to spread, without repeat treatments every few weeks.

Cleanroom-style facility floor representing the controlled environments SGH assesses for indoor air quality
Indoor Air Quality (IAQ)

Assessment and monitoring for the air you can't see

What it is: Assessment of the environmental conditions inside your building, covering parameters such as temperature, humidity, carbon dioxide, particulate matter and other indoor air indicators, plus cleaning of the ventilation ducts that carry that air.

Who needs it: Facilities where visual cleanliness doesn't tell you what's in the air: offices, hospitals, hotels, manufacturing and any building where air-conditioning maintenance has been neglected.

1

Assess

Assess relevant IAQ parameters for your facility.

2

Identify

Identify potential IAQ issues, including duct insulation deterioration and stagnant airflow.

3

Clean

Clean and disinfect ventilation ducts using specialised tools.

4

Recommend

Recommend practical improvements.

5

Monitor

Set a monitoring or maintenance schedule.

What you get: Objective information on air you can't see, cleaner ducts that stop breeding bacteria and mould spores, improved airflow and HVAC efficiency, and fewer costly repairs from deferred maintenance.

Site assessments

Know before you clean

Visual cleanliness doesn't prove control. These assessments give you evidence instead of appearance.

Surface contamination analysis

Assesses particulate and microbiological contamination on surfaces that may look clean. Helps identify areas of concern and verify whether cleaning and contamination-control measures are working, including before-and-after testing for certain treatments.

Moisture and mould risk assessment

Identifies moisture intrusion, condensation, humidity and drying conditions that lead to mould, so you can act on risk conditions early, before a visible mould problem becomes extensive.

Ventilation and airflow evaluation

Examines how effectively air moves through a building or controlled environment, and recommends improvements where stagnant areas or uneven conditions are reducing environmental performance.

FAQ

Frequently asked questions

What is contamination control, and why is it important?
Contamination control is the systematic prevention, reduction and management of unwanted particles, microorganisms, moisture and other contaminants in an environment. It matters most where cleanliness and environmental control directly affect product quality, patient safety, manufacturing performance, regulatory compliance or operational reliability.
Can SGH assess contamination rather than simply clean it?
Yes. Our approach focuses on measurement, assessment and prevention, not just visual cleanliness. We assess surface contamination and environmental conditions to identify sources, establish baseline conditions and evaluate whether corrective measures are working.
What is antimicrobial nano-coating, and how long does it last?
It's a specialised surface treatment that forms a protective layer to inhibit microorganisms on suitable surfaces. Service life depends on the coating, the surface, the environment, cleaning frequency and chemical exposure; some applications hold up for several months. We assess your application and recommend an appropriate treatment and maintenance plan rather than assuming one coating suits every environment.
Can SGH assess indoor air quality?
Yes. We assess environmental conditions such as temperature, humidity, carbon dioxide and particulate matter to identify IAQ issues and give practical recommendations for improvement.
Can SGH identify moisture and mould risks before mould becomes a major problem?
Yes. We assess areas where moisture intrusion, condensation or inadequate drying may create conditions favourable to mould, so risk conditions can be caught and corrected early.
Does SGH only provide one-off services?
No. We provide both one-off assessments and planned hygiene programmes, with scheduled assessment, treatment, maintenance and follow-up for organisations with ongoing requirements.
