Common questions
Curtain fire-retardant treatment FAQs
Practical answers about on-site treatment, certificates, retreatment, timing and cleaning.
Ask about your curtainsAre curtains treated while they are hanging?
Yes. We treat curtains on site while they remain hanging, avoiding removal and reducing disruption.
When will I receive the fire-retardant certificate?
Your Certificate of Fire Retardant Treatment is issued after completion and payment and records BS 5867 Part 2 Type B treatment.
When is curtain retreatment required?
Our certificates state that retreatment is required after five years or five dry-cleaning cycles, whichever occurs first. Curtains must be retreated earlier if washing or another cleaning process removes the treatment.
How long will the work take?
Most jobs are completed within a few hours. Large theatre-style work is usually completed in up to four hours.
Will treatment damage or mark the fabric?
A professional water-based fire retardant is suitable for most fabrics. Sample testing is recommended for delicate or unusual materials.
Do domestic curtains require this treatment?
The service is intended for public and commercial spaces. Private domestic curtains do not normally require this treatment.
Do the curtains need cleaning first?
Dirty or dusty curtains should be cleaned before treatment. Cleaning and fireproofing can be arranged together.
