Fire stopping across Maynard's Green

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How we handle fire stopping in Maynard's Green

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. 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. If you’re dealing with unsealed penetrations discovered above suspended ceilings and fire seals cut back for extra cables and never reinstated, we can help. One point of contact handles commercial sealant work in Maynard's Green from the first photographs to the final walk-round, for single jobs and planned programmes alike.

For a smaller site near Maynard's Green, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.

Work we carry out in East Sussex comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

What the job involves on each surface

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter and we work within those limits.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork usually needs a different solution set by the designer and we flag that rather than guess.

Signs you need fire stopping in Maynard's Green

Plenty of openings were simply never closed. They come to light during inspections, refits or when another trade lifts a tile.

Most enquiries start with something like this:

  • Hidden openings found during inspections
  • Fire-stopping items raised at inspection or handover
  • Fire stopping installed outside its tested range
  • Fire-rated sealant that has cracked or shrunk back

For a building such as Christ Church, new heating or data runs are the usual reason penetrations need sealing.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Is the sealant right for the movement and the substrate?
  • Are they CHAS accredited or on Constructionline?
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

From enquiry to sign-off

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Maynard's Green are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Tell us what induction or permit system the site runs
  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints

Advice

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Fire risk assessments, a job for a competent assessor
  • Plastic pipes whose detail calls for a collar or wrap
  • Gaps in walls that were never built as compartment walls

If you’re not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Where we work in Maynard's Green

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

What happens if it’s left?

Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed. Around Maynard's Green, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

A quote for service penetrations depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

Why appoint us

  • Constructionline member for supplier checks
  • Over 20 years of commercial sealing
  • Clear, fixed quotes
  • Failed material removed, not covered up

Your questions answered

Will you take on work at estates like Ghyll Road Industrial Estate, close to Maynard's Green?

Yes. Estates, retail parks and business parks around Maynard's Green, Ghyll Road Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is Maynard's Green off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you seal any opening with fire-rated sealant?

No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution, as set out by the designer.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Will you write the fire-stopping specification?

No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements, and tell you if a detail needs another product.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

What changes on 2 September 2029?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications. Scotland follows its own Technical Handbook, including clause 2.1.14 on service penetrations.

Compartment walls and floors in Maynard's Green

In England, Approved Document B covers fire stopping of 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. Either way, we install the specified product to its tested detail. Central London is about 41 miles from Maynard's Green. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Where a unit on an estate such as Ghyll Road Industrial Estate, which lies north of Maynard's Green, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Holiday works at schools like Maynards Green Community Primary School often leave service openings to seal before pupils return.
