Fire stopping for businesses in Butler's Cross

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

Common problems we fix in Butler's Cross

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.

Look out for the following:

  • Hidden openings found during inspections
  • Expanding foam used as fire stopping
  • Open linear gaps along the top of fire-resisting walls
  • Snag lists that include open service penetrations

On a site such as Station Approach Business Park, 1.4 miles to the north-east of Butler's Cross, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

What your quote should include

  • How long is the guarantee, and what does it include?
  • Do they follow the manufacturer’s priming guidance?
  • Their plan for phasing and protecting the area
  • What site paperwork they can supply

Choosing a commercial sealant contractor

Fire stopping in Butler's Cross

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. We work to the product’s tested detail for every seal. We work on linear gaps at wall heads, pipe penetrations and service gaps in risers, and what we’re called in for most is damaged fire seals in risers and voids and head-of-wall gaps with no fire seal. Facilities teams, main contractors and managing agents in Butler's Cross tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A job near Butler's Cross is normally planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

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

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • Plastic pipes whose detail calls for a collar or wrap
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire doors, dampers or other fire safety equipment

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Surfaces we seal

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

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around Butler's Cross can be grouped with others nearby. A fixed quote is given before anything starts.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Explain the parking and delivery arrangements
  • Confirm the product named in the specification
  • Let building users know which areas are affected

Ask for a quote

Advice

Why deal with it now?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. Around Butler's Cross, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

A quote for service penetrations depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

Why us?

  • Failed material removed, not covered up
  • Our applicators hold CSCS cards
  • Work to your specification and the manufacturer’s guidance
  • CHAS accredited

Quoting for work in Butler's Cross

These are the things that shape the price:

  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first
  • Specialist products, such as fire-rated or hygienic sealants
  • Quantities, in metres or numbers

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • When you need the work done
  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • Where the site is, with the postcode

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, call 01277 525 020 or email us.

Maintenance after handover

For the best life from the joints:

  • Record which product was used where
  • Don’t let anyone top up a fire seal with the wrong product
  • Include service cupboards in routine inspections
  • Leave fire sealant to cure fully before covering it

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.
