About our fire stopping in Durrant Green

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations, and the usual reasons a site gets in touch are openings left by services added after handover and penetration schedules that need working through. One point of contact handles commercial sealant work in Durrant Green from the first photos to the final walk-round, whether it’s one building or several.

Around smaller places like Durrant Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why act early in Durrant Green

A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Around Durrant Green, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Why us?

  • CSCS-carded applicators
  • Products installed to the manufacturer’s instructions
  • Health and safety: CHAS accredited
  • One number for every site we cover

See our cost guide and our accreditations.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Settle who seals which penetrations at the start of a project
  • Leave fire sealant to cure fully before covering it
  • File the specified details where the next contractor can find them
  • Have penetrations checked while they can still be seen

During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Service penetrations in Durrant Green buildings

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 44 miles from Durrant Green. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

Holiday works at schools like St Michael's Church of England Primary School often leave service openings to seal before pupils return. Office fit-outs on sites such as Business Park, 2.3 miles south-west of Durrant Green, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Halls and meeting rooms at places like Church of St Michael sometimes gain new services, and any compartment wall crossed needs the specified seal.

Durrant Green is about 8 miles west of Ashford, in Kent. Our applicators travel to Durrant Green for work on service penetrations. Across Kent, 931 places are covered, Durrant Green among them. Brighton is covered too, around 40 miles from Durrant Green.

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • Issuing fire ratings or certificates for seals
  • Plastic pipes whose detail calls for a collar or wrap
  • Deciding what a wall or floor needs, which belongs to the designer

Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly.

Where we work in Durrant Green

  • Joints between fire-resisting walls and floors
  • Cable penetrations
  • Linear gaps at wall heads
  • Small duct penetrations where the tested detail allows
  • Pipe penetrations
  • Service gaps in risers

Our process

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Rural sites near Durrant Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • For older buildings, check the asbestos register before work
  • Arrange parking or a loading space
  • Tell us what induction or permit system the site runs

Related advice

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Questions we are asked in Durrant Green

Is Durrant Green too far out for you?

No. Places such as Durrant Green are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

What happens to BS 476 references for fire stopping in Durrant Green?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

How long does a job like this take?

That varies with the scale of the job, though a typical visit typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Can you work while the building is occupied?

In the majority of cases, yes. We phase the work so most of the building stays in use.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
