Fire stopping for Stoke sites

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

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Plastic pipes whose detail calls for a collar or wrap
  • Reviewing a building’s overall fire safety
  • Deciding what a wall or floor needs, which belongs to the designer

If you’re not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer.

Where we work in Stoke

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

Fire stopping for commercial buildings in Stoke

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Stoke. If you have penetration schedules that need working through and unsealed penetrations discovered above suspended ceilings, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Stoke it comes down to the same thing: the right product in a properly prepared joint.

Rural conversions around Stoke can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Why it’s worth doing now in Stoke

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Older rural buildings around Stoke move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

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

Why us?

  • Constructionline member for supplier checks
  • Over 20 years of commercial sealing
  • Failed material removed, not covered up
  • Work to your specification and the manufacturer’s guidance

Building owners, agents and FMs in Stoke

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

We work for building owners and managing agents on everything from one building to a spread of sites around Stoke. Several sites can go on one quote, so there’s one set of paperwork to deal with.

What affects the price in Stoke

Your fixed quote is built from the real scope. It takes account of:

  • Working within restricted access windows
  • How accessible the joints are
  • How much there is to seal
  • Which sealant the job calls for

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • Approximate linear metres or a joint schedule
  • Your programme or deadline
  • The site address and postcode
  • Specification clauses that apply

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email us with what you know.

How the job changes by surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones normally call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.

Metal pipes

Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near Stoke need work, visits can be combined. A fixed quote is given before anything starts.

  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. 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.

Before we start on site

  • Make sure the joints can be reached
  • Agree which areas must stay open
  • Warn occupants and staff about the work

Ask for a quote

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, phone 01277 525 020 or email us.

Advice

Common questions from Stoke clients

Will you plan work around the academic year at somewhere like University of Greenwich - Medway?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work on a hospital site such as Medway Maritime Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

How long does a job like this take?

It depends on the scope, but the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you work in Scotland as well as England?

Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.

Fire stopping in Stoke: the local picture

Central London is about 31 miles from Stoke. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment 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.

At a university such as University of Greenwich - Medway, which lies south-west of Stoke, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Schools such as Stoke Primary Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. In a building such as Church of St Peter and St Paul, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Stoke is about 5 miles north of Gillingham, in Medway. Across the ME3 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 54 places in Medway, from busy centres to rural villages. Sites around London have their own page, roughly 31 miles from Stoke.

Postcode districts covered here: ME3. Buildings on Vicarage Lane and Vicarage Close are within our area for service penetrations. Just outside Stoke, we also work in Middle Stoke (1 mile east), Lower Stoke (1 mile north-east), North Street (1 mile south-west), Tunbridge Hill (1 mile south-west) and St Mary Hoo (1 mile north-west). Nearby towns on our patch include Gillingham (5 miles south), Chatham (7 miles south-west), Rochester (7 miles south-west), Rainham (6 miles south), Strood (7 miles south-west) and Luton (6 miles south-west).
