Fire stopping in Tye Green

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. Site teams most often ask us about fire sealant pulled out of the opening and open linear gaps along the top of fire-resisting walls, across joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads. Looking for mastic applicators who cover Tye Green? We’ve been sealing commercial buildings since 2005.

Smaller places such as Tye Green still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Tye Green, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  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. We fit the backing the detail asks for, to the stated depth.
  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

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Tell us what induction or permit system the site runs

When to bring in a specialist

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. A poor seal in places like these tends to cost more to put right later.

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.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • File the specified details where the next contractor can find them
  • Settle who seals which penetrations at the start of a project
  • Get seals inspected before ceilings and boxing close
  • Brief every trade that openings they make must be sealed

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts.

Fire stopping in Tye Green: the local picture

The 2 miles around Tye Green include two care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Tye Green lies roughly 38 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.

In a school such as Cressing Primary School, fire-rated sealant goes in around service penetrations where it is specified. For a building such as St Barnabas, new heating or data runs are the usual reason penetrations need sealing.

Tye Green is about 2 miles south-east of Braintree, in Essex. Across the CM77 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 644 places across Essex fall within our area, Tye Green among them. For work in that direction, see our London page, about 38 miles away.

If you need fire stopping in CM77, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

What sets the cost

What shapes the price:

  • The site’s rules and procedures
  • Location, for remote and island sites
  • Access and working height
  • How much there is to seal

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • The site address and postcode
  • Whether the building will be occupied during the work
  • Access details, including height
  • The asbestos register, for older buildings

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send photos by email.

Questions we’re asked in Tye Green

Is hospital work, at somewhere like Braintree Community Hospital, something you do?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Does your area include sites such as Lanham Business Park, near Tye Green?

Yes. Estates, retail parks and business parks around Tye Green, Lanham Business Park among them, are all within reach. Photos and a short description are enough for a first look.

How long does a typical visit take?

It depends on the scope, but the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we’ll set out a timescale with the quote.

Which standards are fire seals tested to?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.

Do you cover Tye Green?

Yes. Tye Green is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or use the quote form.

Will you write the fire-stopping specification?

No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it and point out anything needing another product.

Are you insured?

Yes. We are fully insured, including public liability cover.

Common problems we fix in Tye Green

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it.

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

  • Non-fire-rated filler around services
  • Fire sealant pulled out of the opening
  • Penetration schedules that need working through
  • Seals that don’t match their tested detail

On a hospital site such as Braintree Community Hospital, 2.6 miles to the north-west of Tye Green, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

What we can’t put right

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Gaps in walls that were never built as compartment walls
  • Writing the fire-stopping specification
  • Signing off or certifying a building’s fire stopping

If you are not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

What we seal

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