Fire stopping for Little Baddow sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What the job involves on each surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail. We confirm material and size first and tell you if sealant isn’t the right product.

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Fire stopping for commercial buildings in Little Baddow

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. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are fire sealant pulled out of the opening and fire seals cut back for extra cables and never reinstated. Facilities teams, main contractors and managing agents in Little Baddow tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a smaller site near Little Baddow, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

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

General trades versus a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Questions about Little Baddow

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Little Baddow?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is Little Baddow too small for you to travel to?

No. Places such as Little Baddow are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How many days will you need on site?

That varies with the scale of the job, though a typical visit normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

What do you charge?

There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.

How the quote is worked out

A fixed quote reflects the actual work. It allows for:

  • Induction, permit and paperwork requirements
  • Any access equipment needed
  • The size and state of each joint
  • Whether the work must be split into stages

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Send us:

  • The product your specification calls for
  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • Your programme or deadline

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email us.

Work for main contractors and building owners

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

When to call us in Little Baddow

A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position, so it has to come out.

Typical triggers for a call:

  • Open linear gaps along the top of fire-resisting walls
  • Service penetrations left open after M&E works
  • Openings found when ceilings come down for a refit
  • Seals disturbed by maintenance and left open

On a hospital site such as Priory Hospital (3.7 miles west of Little Baddow), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

How to choose a sealant contractor

Service penetrations in Little Baddow buildings

Central London is about 33 miles from Little Baddow. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

Residences at universities like Anglia Ruskin University, 4.4 miles to the west of Little Baddow, have compartment walls that must be resealed whenever services change. In a building such as Church of St Mary the Virgin, any service penetration through a fire-resisting wall should be sealed to the specified detail.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Little Baddow are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Warn occupants and staff about the work
  • Flag any permit to work we’ll need
  • Move anything stored against the joints
