Fire stopping in Rush Green, done properly

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Rush Green. Site teams most often ask us about expanding foam used as fire stopping and fire stopping installed outside its tested range, on pipe penetrations, joints between fire-resisting walls and floors and cable penetrations. Whoever orders the work in Rush Green, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Fire-rated sealing in a place like Rush Green is normally a single building at a time. Send the specification, drawings or photos of the openings and we’ll quote to suit.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Rush Green: questions and answers

Do you work on fire-rated sealing in hotels in Rush Green?

Yes, to the specification and the product’s tested detail. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Can you work at a site such as Newman Industrial Estate, by Rush Green?

Yes, sites like Newman Industrial Estate are within our area, along with the rest of Rush Green. A few photos and the unit address let us price the work.

Can weather delay the job?

For external joints, 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.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months on every job.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Compartment walls and floors in Rush Green

In England, Approved Document B covers fire stopping of 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. There are plenty of hotels within about 2 miles of Rush Green. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.

Large healthcare estates like Clacton Hospital (to the south-east of Rush Green) change their services often, so penetration seals are worth checking after M&E work. Where a unit on an estate such as Newman Industrial Estate, less than half a mile east of Rush Green, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Rush Green is about 1 mile south-west of Clacton-on-Sea, in Essex. Our applicators travel to Rush Green for work on service penetrations. Rush Green is one of 644 places in Essex on our list. For work in that direction, see our London page, about 56 miles away.

Work on service penetrations is covered throughout CO15 and CO16, for business premises of every kind. For a building on Leas Road, Ford Road and Cloes Lane or nearby, send details and we will quote for service penetrations. Close to Rush Green, our area also takes in Bocking's Elm (1 mile north), Clacton-on-Sea (1 mile north-east), Jaywick (1 mile south-west), St Osyth (2 miles west) and St Osyth Heath (2 miles north-west). A short drive away, we cover Colchester (12 miles north-west), Harwich (11 miles north-east), Camulodunum (13 miles north-west), Greenstead (11 miles north-west), Wivenhoe (9 miles north-west) and Brightlingsea (5 miles west).

What the job involves on each surface

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.

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.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements

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

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • Drawings or a marked-up plan, if available
  • A wide shot and a close-up of the area
  • Whether the building will be occupied during the work
  • Anything awkward about access or site hours

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or email a schedule or drawings.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. For a job in Rush Green, the main thing is a clear picture of the work. A fixed quote follows.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand
  • Move anything stored against the joints

Advice

Commercial clients in Rush Green

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Walls or floors that aren’t fire-resisting to begin with
  • 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 email us and we will give you a straight answer.

Joints and surfaces we work on

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

What we’re called out for in Rush Green

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.

If one of these sounds familiar, it’s time for a closer look:

  • Fire stopping installed outside its tested range
  • Fire sealant pulled out of the opening
  • Open linear gaps along the top of fire-resisting walls
  • Unsealed penetrations discovered above suspended ceilings

In a hotel such as Dudley's Hotel, which lies south-east of Rush Green, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Questions to ask before you book

  • What level of public liability insurance do they hold?
  • Who will actually carry out the work
  • How the existing material will be dealt with
  • Which product they’ll use, and why it suits the joint
