Fire stopping in Tidworth

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Tidworth: questions and answers

Can you work at a site such as Castledown Business Park, by Tidworth?

Yes. Estates, retail parks and business parks around Tidworth, Castledown Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

Is Tidworth too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you work in Scotland as well as England?

Building standards in Scotland are separate from England’s, and England uses Approved Document B. Either way, we install the specified sealant to its tested detail.

Will you sign off the seals for us?

No. Approval sits with the designer, principal designer or building control. We’ll confirm the products and details used.

Do you have third-party installer accreditation for fire stopping?

No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t. Where it isn’t required, we install the specified sealant to the maker’s details.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

What does an EI 60 rating mean?

The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement and the installation has to match the test.

How we handle fire stopping in Tidworth

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail. Site teams most often ask us about seals that don’t match their tested detail and penetration schedules that need working through, on service gaps in risers, linear gaps at wall heads and cable penetrations. One point of contact handles commercial sealant work in Tidworth from the first photographs to the final walk-round, whether it’s one building or several.

Around smaller places like Tidworth, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Do you need fire stopping in Tidworth?

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

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

  • Penetration schedules that need working through
  • Unsealed penetrations discovered above suspended ceilings
  • Fire sealant pulled out of the opening
  • Service penetrations left open after M&E works

Office fit-outs on sites such as Castledown Business Park, 1.7 miles to the north-east of Tidworth, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

What your quote should include

  • How they’ll work around occupants
  • How joint depth will be controlled
  • What level of public liability insurance do they hold?
  • Health and safety accreditation such as CHAS

Choosing a commercial sealant contractor

Honest limits

We check first that sealant really is the fix. It isn’t the answer for:

  • Issuing fire ratings or certificates for seals
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Openings that need collars, wraps, batts or boards rather than sealant

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Where we work in Tidworth

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

Looking after the joints

After handover, a little attention goes a long way:

  • Keep product data and details in the fire safety file
  • Brief every trade that openings they make must be sealed
  • Include service cupboards in routine inspections
  • Arrange inspection before areas are covered up

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.

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

Fire-rated sealing for Tidworth buildings

At about 70 miles from central London, Tidworth is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Either way, we install the specified product to its tested detail.

Schools such as The Wellington 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 the Holy Trinity, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Why act early in Tidworth

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If neighbouring businesses or buildings around Tidworth need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  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. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints
  • Send any specification or drawings in advance

Advice

What the job involves on each surface

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables and we work within those limits.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.
