Fire stopping across Stoke Charity

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

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough, and we will never swap a specified collar for sealant.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork usually needs a different solution set by the designer.

Fire stopping in Stoke Charity, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. If you have improvised or mixed-product fire seals and fire-stopping items raised at inspection or handover, we can put it right, on joints between fire-resisting walls and floors, service gaps in risers and pipe penetrations alike. Whoever orders the work in Stoke Charity, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Stoke Charity, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Our workmanship is guaranteed for 12 months, in Stoke Charity as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about Stoke Charity

Is Stoke Charity off your patch?

Not at all. Stoke Charity is within our area. 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.

How does the move away from BS 476 affect penetration seals in Stoke Charity?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

How long will the new sealant last?

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

Can you work while the building is occupied?

Normally, yes. Phased work can be planned so areas stay in use.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Maintenance after handover

To get the most from the new sealant:

  • File the specified details where the next contractor can find them
  • Keep general-purpose fillers away from compartment walls
  • Have penetrations checked while they can still be seen
  • Flag new cables with no seal around them

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Issuing fire ratings or certificates for seals
  • Fire doors, dampers or other fire safety equipment
  • Openings that need collars, wraps, batts or boards rather than sealant

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think.

What we seal

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

Do you need fire stopping in Stoke Charity?

Openings in fire-resisting walls typically appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

It’s worth sending us details if you spot any of the following:

  • Fire-rated sealant that has cracked or shrunk back
  • Non-fire-rated filler around services
  • Improvised or mixed-product fire seals
  • Openings left by services added after handover

Older community buildings such as Church of St Michael that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

  • What level of public liability insurance do they hold?
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

Fire stopping around Stoke Charity: what changes locally

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. A number of hotels sit less than 2 miles from Stoke Charity. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Rural sites near Stoke Charity may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  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. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Point out any areas we must not close
  • Share the asbestos register for older buildings

Get a fixed quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

Cost factors for service penetrations

The price varies from site to site. Expect it to depend on:

  • Travel to remote or island sites
  • Working within restricted access windows
  • Removal of failed or old sealant
  • The total length or number of joints

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Sending details for a quote

Diagnosis starts before we arrive. Let us know:

  • When you need the work done
  • Whether an asbestos survey exists
  • Clear photographs of the problem areas
  • The product your specification calls for
