Fire stopping in Stisted, done properly

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. 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, not a rule of thumb. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and cable penetrations, and the usual reasons a site gets in touch are unsealed openings around new pipes and cables and unsealed penetrations discovered above suspended ceilings. Whoever orders the work in Stisted, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

A job near Stisted is normally planned around one visit, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Cost factors for service penetrations

A fixed quote reflects the actual work. It takes account of:

  • Phasing around occupants
  • The site’s rules and procedures
  • Access and working height
  • Distance, for remote addresses

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Whether the building will be occupied during the work
  • Where the site is, with the postcode
  • Any specification or named product
  • How the joints are reached, and at what height

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email us.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Stisted, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  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. 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. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Have the specification and drawings to hand
  • Tell us what induction or permit system the site runs
  • Arrange parking or a loading space

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call the office on 01277 525 020 or email the details over.

Related advice

Do you need fire stopping in Stisted?

Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access usually bring them to light.

What tends to prompt an enquiry:

  • Open linear gaps along the top of fire-resisting walls
  • Builders’ foam or ordinary silicone in compartment walls
  • Fire stopping installed outside its tested range
  • Seals disturbed by maintenance and left open

For a building at a site such as Lanham Business Park, 2 miles south of Stisted, a check of penetration seals after each fit-out is good practice.

What to look for in a quote

  • Their public liability cover
  • How they’ll work around occupants
  • Which product they’ll use, and why it suits the joint
  • Their pre-qualification and accreditations

How to choose a sealant contractor

Compartments and services around Stisted

Stisted lies roughly 41 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Either way, we install the specified product to its tested detail.

Wherever services are added at a hospital such as St Michael's Hospital, 3.3 miles west of Stisted, the compartment line has to be made good with the specified product. Colleges such as Braintree College (to the west of Stisted) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Stisted: questions and answers

Is a hospital such as St Michael's Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Will you take on work at estates like Lanham Business Park, close to Stisted?

Yes. Our area takes in Stisted and its surroundings, with estates and business parks such as Lanham Business Park included. A few photos and the unit address let us price the work.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

What will the job cost?

Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or use the quote form.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

After the work

Once the work is signed off, these steps help:

  • Leave fire sealant to cure fully before covering it
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Agree the fire-stopping specification before services go in
  • Don’t let anyone top up a fire seal with the wrong product

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. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

When to bring in 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 where general trades tend to cut corners.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

How the job changes by surface

Linear joints

Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough.
