Getting started
Understanding the service
What fire-retardant treatment services do you provide?
We treat suitable curtains, fabrics, upholstery covers, artificial plants, dried flowers, untreated timber, props, displays, tents, marquees and other commercial materials. We also provide on-site curtain cleaning and fireproofing.
Do you cover the whole of the UK?
Yes. We provide nationwide commercial services from our base in Colchester, Essex. Quotations consider the project size, location and whether work is completed on-site or in-house.
How do I request a quotation?
Tell us what needs treating, the approximate dimensions or quantities and where it is located. If you have been given a specific requirement, include the wording.
How quickly can treatment be arranged?
Availability varies with location, project size and existing bookings. Fast turnarounds are often possible, but we confirm timing only after reviewing the material and drying requirements.
Standards and certificates
Understanding the paperwork
What certificate will I receive?
After treatment and payment, we issue a Certificate of Fire Retardant Treatment. It identifies the treated items, the site, the treatment completed and the confirmed standard for your records.
Is a treatment certificate the same as a laboratory fire-test report?
No. A treatment certificate records the work completed for your project, while a laboratory report records the performance of a tested product or system. If you have been asked for additional documents, send us the exact wording before treatment.
Which fire standard does my material need to meet?
Tell us what the material is and where it will be used. We will confirm the normal treatment standard and the certificate we can provide. If your venue, insurer or fire consultant has specified a requirement, send us the exact wording.
When will the certificate be issued?
The certificate is issued electronically after the treatment has been completed and payment has been received. It is supplied as a PDF for your fire-safety records.
When is retreatment required?
Your certificate and maintenance notes explain when retreatment is required. Timing depends on the material, treatment system, cleaning, washing and weathering. Curtain certificates state five years or five dry-cleaning cycles, whichever comes first.
Treatment suitability
Knowing what can be treated
Can every material be fire-retardant treated?
No. Suitability depends on absorbency, construction, existing coatings, condition, appearance requirements and the required standard. We’ll tell you before booking if the material is unsuitable.
Why might sample testing be recommended?
A sample helps assess absorption, drying, colour, feel and surface appearance before treating the full item. It is particularly useful for delicate, valuable, coated, brightly coloured or unfamiliar materials.
Can waterproof, stain-resistant or coated materials be treated?
These finishes can prevent normal absorption, so treatment may be ineffective or remain visible on the surface. Product information and sample testing are often needed. Polypropylene and other water-resistant materials require particular care.
Will treatment change the colour, feel or appearance?
Most suitable materials show little visible change once dry. Results vary by material and finish, and we will advise if a sample check is sensible before the full treatment.
Is shrinkage possible with water-based treatment?
Yes. Although many fabrics treat successfully, water-based application can cause temporary movement or permanent shrinkage in susceptible materials. This cannot be guaranteed against, so sample testing is recommended where dimensions are critical.
Drying and aftercare
Looking after treated materials
How long does treatment take to dry?
Drying depends on the material, application rate, temperature and ventilation. Many fabric projects need approximately 24 hours at room temperature. We confirm the practical drying arrangements for each project.
Can treated items be moved before they are fully dry?
Many absorbent treated items can be moved carefully after application, provided they are not folded, stacked or disturbed in a way that affects drying. Shiny plastics rely on surface drying and should normally remain in place until dry.
Does washing or cleaning remove the treatment?
Water washing and extraction cleaning can remove or reduce many applied treatments. Suitable fabric treatments generally allow up to five dry-cleaning cycles, but the precise aftercare depends on the material and treatment system.
When should materials be retreated?
Retreatment is required when the stated validity ends, the permitted cleaning limit is reached or the material has been washed, heavily cleaned, weathered, damaged or changed in a way that may affect performance.
Material guidance
Common questions by material
What standard normally applies to commercial curtains?
Curtains and drapes in public and commercial places are required to comply with BS 5867. Part 2 Type B is the normal requirement for most public-place curtains, with Type C applying where the higher performance level is specified. We provide the competent treatment and Certificate of Fire Retardant Treatment needed for your compliance records.
Do curtains need cleaning before fireproofing?
Not always. Cleaning is recommended where curtains are dusty, stained, affected by odours or heavily soiled. The combined service can normally clean and treat curtains on-site while they remain hanging.
Can treatment convert ordinary furniture into Crib 5 furniture?
No. This service treats suitable external textile covers to BS 5852 Part 1. It does not change or certify the foam, fillings, frame or complete item, and cannot convert furniture into Crib 5 furniture.
What timber can be treated to B-s2,d0?
Our impregnation route is for suitable raw, absorbent, untreated wood. It can be applied on site or before installation. Painted, varnished, sealed or non-absorbent timber is not suitable.
Can artificial plants and shiny plastic foliage be treated?
Many artificial plants can be treated to BS 5852 or BS 5867 where that standard is agreed for the decorative display. Post-treatment cannot provide BS EN 13501-1 Class B; only inherently fire-retardant plastic foliage can achieve this classification.
Can dried flowers, paper, cardboard and props be treated?
Dried flowers, grasses, foliage and many absorbent decorative materials can be treated. Send us the material details and we will confirm the suitable treatment. A sample check may be recommended for an unusual material or finish.
Which standard normally applies to tents and marquees?
BS 7837 is often requested for tents and marquees used for events. Send us the material details and the requirement you have received, and we will confirm whether treatment is suitable.
Arranging the work
Timing and payment
Can commercial customers send or deliver items for treatment?
Yes, suitable items can sometimes be treated in-house. Deliveries must be arranged in advance so handling, treatment space, drying and return collection can be planned.
How should the site be prepared?
We confirm requirements before arrival. These may include protection of nearby surfaces, suitable room temperature and ventilation, water or power where required and enough undisturbed space for treated materials to dry.
What payment methods do you accept?
Invoices are issued through QuickBooks and include payment options for debit or credit card, bank transfer and PayPal. The treatment certificate is issued after the completed work has been paid for.
