Fire stopping for Broughton sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Maintenance after handover

Once the work is signed off, these steps help:

  • Settle who seals which penetrations at the start of a project
  • Get seals inspected before ceilings and boxing close
  • Include service cupboards in routine inspections
  • Record which product was used where

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there instead of being left for someone else.

Fire stopping in Broughton, done properly

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. The enquiries we see most involve damaged fire seals in risers and voids and open linear gaps along the top of fire-resisting walls, across linear gaps at wall heads, joints between fire-resisting walls and floors and pipe penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Broughton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Broughton still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. 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, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire risk assessments, a job for a competent assessor
  • Approving the work on behalf of building control

If you are not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Broughton need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  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.

What we need from you

  • Tell us what induction or permit system the site runs
  • Point out parking and an unloading spot
  • Confirm the product named in the specification

Getting a fixed quote

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 will arrange a site visit if anything is unclear.

Related advice

Do you need fire stopping in Broughton?

Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.

Clients usually get in touch after noticing one or more of the following:

  • Service penetrations left open after M&E works
  • Damaged fire seals in risers and voids
  • Old intumescent sealant that has split away
  • Penetration schedules that need working through

On a site such as Vantage Business Park (0.9 miles south-east of Broughton), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • Will RAMS and insurance details be available?
  • Can the work be phased to keep areas open?
  • Will failed sealant be removed rather than covered?

Our contractor checklist

Compartments and services around Broughton

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. Broughton is about 67 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

Shop fits in centres such as Castle Quay Shopping Centre, 2.6 miles to the north-east of Broughton, can bring new services through fire-resisting walls between units, which then need the specified seal. For a site team at a college like Oxford and Cherwell Valley College, 1.9 miles north-east of Broughton, fire-rated sealing is best scheduled after the summer works.

Broughton is about 2 miles south-west of Banbury, in Oxfordshire. If you’re looking for fire stopping in Broughton, we can help, as we do across Oxfordshire. Broughton is one of 423 places we cover in Oxfordshire. There’s a separate page for Oxford, roughly 21 miles from Broughton.

If you need fire stopping in OX15, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Questions we’re asked in Broughton

Can work at a site such as Oxford and Cherwell Valley College fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is a smaller place like Broughton outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Do you approve fire stopping for building control?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Can you handle several sites?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Quoting for work in Broughton

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Joint width, depth and condition
  • How much existing material needs removing
  • Phasing around occupants
  • The site’s rules and procedures

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • Asbestos survey details if the building is older
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back
  • The type of building and who uses it

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email a schedule or drawings.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
