Fire stopping in Bunce Common

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. 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 rather than guesswork. Most enquiries involve penetration schedules that need working through and head-of-wall gaps with no fire seal, across pipe penetrations, cable penetrations and service gaps in risers. Whoever orders the work in Bunce Common, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural conversions around Bunce Common 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.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Commercial clients in Bunce Common

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Looking after the joints

Regular inspection catches problems early. In particular:

  • Include service cupboards in routine inspections
  • Keep product data and details in the fire safety file
  • Don’t let anyone top up a fire seal with the wrong product
  • Agree the fire-stopping specification before services go in

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail.

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.

Compartments and services around Bunce Common

Bunce Common lies roughly 22 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. 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.

Older community buildings such as Church of St Bartholomew that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Wherever services are added at a hospital such as Dorking Community Hospital, 2.7 miles to the north-west of Bunce Common, the compartment line has to be made good with the specified product.

Bunce Common is about 3 miles south-east of Dorking, in Surrey. Anywhere in RH2, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Bunce Common is one of 379 places we cover in Surrey. For work in that direction, see our London page, about 22 miles away.

We take on service penetrations across the RH2 and RH3 postcode area, for business premises of every kind. Streets here include Gadbrook Road, Leigh Road and Shellwood Road, and sites on any of them can send details for a fixed quote. Just outside Bunce Common, we also work in Dawesgreen (1 mile east), Strood Green (1 mile north), Leigh (1 mile east), Brockham (2 miles north) and Betchworth (2 miles north). Further afield, our area takes in Guildford (13 miles west), Woking (15 miles north-west), Epsom (9 miles north), Horley (5 miles south-east), Redhill (5 miles north-east) and Ewell (10 miles north).

Do you need fire stopping in Bunce Common?

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 what we find most often.

Site and facilities staff are often the first to spot these:

  • Improvised or mixed-product fire seals
  • Openings found when ceilings come down for a refit
  • Open linear gaps along the top of fire-resisting walls
  • Openings left by services added after handover

Office fit-outs on sites such as Chesterfield Business Park, 2.9 miles to the north-east of Bunce Common, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Whether old or failed sealant will be cut out, not overlaid
  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?

Choosing a commercial sealant contractor

Different surfaces, different methods

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • The site’s rules and procedures
  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants
  • How much there is to seal

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What we need to price the job

A few photos plus some basic facts will normally do. It helps to include:

  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available
  • The site address and postcode
  • The asbestos register, for older buildings

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Common questions from Bunce Common clients

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Bunce Common?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Can you work on a hospital site such as Dorking Community Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.

Do you cover Bunce Common?

Yes. Bunce Common is in our area and the rest of Surrey. For a quote, give us a call on 01277 525 020 or email us.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

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’ll price it properly.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking anything from one day to a planned run of visits, depending on the number of seals and the access. Rural sites near Bunce Common may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Point out any areas we must not close
  • Send your site hours and access windows

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send photos by email with what you know.
