Your questions answered

Will you take on work at estates like Southwater Business Park, close to Brooks Green?

Yes. Our area takes in Brooks Green and its surroundings, with estates and business parks such as Southwater Business Park included. Photos and a short description are enough for a first look.

Do you take on work at healthcare sites like Horsham Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you have third-party installer accreditation for fire stopping?

No, and we’d rather be clear about that. Some clients require third-party installer schemes even though the law doesn’t, so check your contract first. Where it isn’t required, we install the specified sealant to the maker’s details.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

How do we ask for a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How we handle fire stopping in Brooks 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. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the failures we are asked to look at most are unsealed penetrations discovered above suspended ceilings and seals that don’t match their tested detail. Searching for sealant specialists in Brooks Green? We’ve been sealing commercial buildings since 2005.

Around smaller places like Brooks Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Work we carry out in West Sussex comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we will arrange a return visit.

Leave it or put it right?

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. One visit to deal with every failing joint makes more sense than several trips to a place like Brooks Green, rather than one at a time. Send photos of each area and we’ll quote for the lot.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Common problems we fix in Brooks Green

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.

These are often picked up first by site or facilities staff:

  • Snag lists that include open service penetrations
  • Openings found when ceilings come down for a refit
  • Non-fire-rated filler around services
  • Old intumescent sealant that has split away

Theatres, wards and plant rooms at sites like Horsham Hospital, 4.7 miles north-east of Brooks Green, all have compartment walls crossed by services.

What to look for in a quote

  • How the joint faces will be prepared and primed
  • What the guarantee covers, and for how long
  • Proof of insurance
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Fire stopping around Brooks Green: what changes locally

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Brooks Green is about 36 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.

On a site such as Southwater Business Park, 1.8 miles to the east of Brooks Green, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Holiday works at schools like Barns Green Primary School often leave service openings to seal before pupils return.

Brooks Green is about 5 miles south-west of Horsham, in West Sussex. Commercial clients in Brooks Green can call on us for service penetrations. Across West Sussex, 373 places are covered, including Brooks Green. Our Brighton page has more on work in that area (17 miles or so).

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a single visit for a short list of penetrations, or a phased programme for a whole building. For work around Brooks Green, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  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.

Getting the site ready

  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints

What sets the cost

What shapes the price:

  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • How much there is to seal

A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • Approximate linear metres or a joint schedule
  • The postcode of the building
  • Any specification or named product
  • When you need the work done

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

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, so we check before sealing.

Small ducts

Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer, and we will say if that applies.
