Fire stopping near Great Bookham

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

Building owners, agents and FMs in Great Bookham

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Fire stopping in Great Bookham, done properly

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Great Bookham. If you have fire seals cut back for extra cables and never reinstated and builders’ foam or ordinary silicone in compartment walls, we can help. Whoever orders the work in Great Bookham, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

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

Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email us and we will come back to it.

Why deal with it now?

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these. For buildings in places like Great Bookham, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Your questions answered

Is Great Bookham too far out for you?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Would you work within a site like Leatherhead Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can the sealant be colour-matched?

Often, 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.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

Will you sign off the seals for us?

No. Sign-off belongs to the designer or building control, not the installer. We will confirm the product and detail installed and agree any further records when we quote.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Brief every trade that openings they make must be sealed
  • Get seals inspected before ceilings and boxing close
  • Include service cupboards in routine inspections
  • Leave fire sealant to cure fully before covering it

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Service penetrations in Great Bookham buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Great Bookham lies roughly 19 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Hospital estates such as Leatherhead Community Hospital, 2.5 miles north-east of Great Bookham, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Schools such as The Dawnay School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Great Bookham is about 6 miles south-west of Epsom, in Surrey. We cover commercial sites throughout Great Bookham. Great Bookham is one of 379 places we cover in Surrey for service penetrations. Sites around London have their own page, roughly 19 miles from Great Bookham.

Signs you need fire stopping in Great Bookham

Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.

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

  • Improvised or mixed-product fire seals
  • Fire-stopping items raised at inspection or handover
  • Damaged fire seals in risers and voids
  • Head-of-wall gaps with no fire seal

In a building such as Church of St Nicolas, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • Will failed sealant be removed rather than covered?
  • Their pre-qualification and accreditations
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. If neighbouring businesses or buildings around Great Bookham need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. We read the specification, drawings or penetration schedule you send.
  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. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Agree which areas must stay open
  • Make sure the joints can be reached
  • Point out parking and an unloading spot

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
