Do you need fire stopping in Chilmington Green?

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.

Any of the following is a good reason to get the joints checked over:

  • Fire sealant pulled out of the opening
  • Fire seals cut back for extra cables and never reinstated
  • Openings left by services added after handover
  • Unsealed joints where partitions meet the slab

At a college such as Ashford College, which lies north-east of Chilmington Green, checking penetration seals after summer M&E works is good practice.

Questions to ask before you appoint anyone

Questions we’re asked in Chilmington Green

Can you work around term dates at a campus such as Ashford College?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is Ellingham Industrial Estate, near Chilmington Green, within your area?

Yes. We cover Chilmington Green and the area around it, including industrial estates, business parks and retail parks such as Ellingham Industrial Estate. A few photographs and the unit address let us price the work.

Will you sign off the seals for us?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Is Chilmington Green in your area?

Yes. We cover Chilmington Green, and the simplest way to start is to call the office on 01277 525 020 or email us.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How do I request a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

How the job changes by surface

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
