Fire stopping for Chafford Hundred sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in Chafford Hundred

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. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and service gaps in risers, and what we are called in for most is seals that don’t match their tested detail and damaged fire seals in risers and voids. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Chafford Hundred is the same: the right product in a properly prepared joint.

Converted and extended buildings around places like Chafford Hundred can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How the job changes by surface

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.

Compartment walls and floors in Chafford Hundred

Fire stopping of openings and penetrations in England falls under Approved Document B. 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. We install whatever has been specified, to the product’s tested detail. A 2-mile radius around Chafford Hundred takes in several hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.

For a unit at a site such as Lakeside Shopping Centre, 1.2 miles west of Chafford Hundred, any new service through a fire-resisting wall should be sealed to the tested detail. Campus buildings at universities such as University of Greenwich (to the south-west of Chafford Hundred) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Hotels such as Europa Hotel, 0.7 miles north of Chafford Hundred, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Chafford Hundred is about 1 mile north-west of Grays, in Thurrock.

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Signing off or certifying a building’s fire stopping
  • Openings that need collars, wraps, batts or boards rather than sealant

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

Your questions answered

Do you cover business parks and estates near Chafford Hundred, such as Lakeside Shopping Centre?

Yes. Our area takes in Chafford Hundred and its surroundings, with estates and business parks such as Lakeside Shopping Centre included. Send details of the unit and the work through our quote form for a quick quote.

Is Chafford Hundred too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

How do we ask for a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email the details over. Include photos or drawings if you have them.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Chafford Hundred can sit alongside others in a wider programme across Thurrock.

What sets the cost

Before we quote, we look at:

  • Induction, permit and paperwork requirements
  • Working within restricted access windows
  • Backing rod, priming and other preparation
  • The product specified

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.

Before you send an enquiry

Whether it’s one area or a whole building, the same details help:

  • Any dates the work must fit around
  • The site address and postcode
  • Any specification or named product
  • Anything awkward about access or site hours

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

From enquiry to sign-off

Working in a building that stays open takes some planning. 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 site in Chafford Hundred, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Share your working hours and any access restrictions
  • Flag any permit to work we will need
  • Make sure the joints can be reached

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
