Fire stopping for Bradville sites

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

After the work

After handover, a little attention goes a long way:

  • Get seals inspected before ceilings and boxing close
  • Foam or ordinary sealant is never a fire-seal repair
  • Settle who seals which penetrations at the start of a project
  • Check with the data sheet before painting over fire sealant

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.

Fire stopping in Bradville, done properly

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. Most enquiries involve unsealed joints where partitions meet the slab and non-fire-rated filler around services, across linear gaps at wall heads, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows. For commercial sealant work in Bradville, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around Bradville, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

How the job changes by surface

Cables and cable bundles

New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and any bundle too large for sealant alone is flagged.

Small ducts

Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking anything from one day to a planned run of visits, depending on the number of seals and the access. Work in places the size of Bradville is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  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. 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

  • Send your site hours and access windows
  • Agree which areas must stay open
  • Have the specification and drawings to hand

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Questions about Bradville

Do you work in occupied care homes around Bradville?

Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.

Is Bradville off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you hold third-party fire-stopping installer certification?

No. We don’t hold a third-party fire-stopping installer certificate. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we will say so straight away rather than waste your time.

How many days will you need on site?

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 will set out a timescale with the quote.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What does an EI 60 rating mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.

Can weather delay the job?

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. Inside work is seldom held up.

Owners, agents and contractors

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Bradville can sit alongside others in a wider programme across Milton Keynes.

Building owners and managing agents use us on everything from one building to a spread of sites around Bradville. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Where services cross fire walls in Bradville

The 2 miles around Bradville 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. We install fire-rated sealant to the tested detail where it is specified. In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail.

At a college such as Milton Keynes College, which lies south-east of Bradville, checking penetration seals after summer M&E works is good practice. Residences at universities like University of Bedfordshire Milton Keynes Campus (to the south-east of Bradville) have compartment walls that must be resealed whenever services change. Hospital estates such as Blakelands Hospital (2 miles north-east of Bradville) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
