Fire stopping in Sarisbury Green, done properly

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. Most enquiries involve open linear gaps along the top of fire-resisting walls and fire stopping installed outside its tested range, on pipe penetrations, cable penetrations and small duct penetrations where the tested detail allows. Whoever orders the work in Sarisbury Green, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Buildings in a smaller place such as Sarisbury Green that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email the details over and we will come back to it.

What we are called out for in Sarisbury Green

Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.

Common reasons buildings call us in:

  • Head-of-wall gaps with no fire seal
  • Unsealed openings around new pipes and cables
  • Non-fire-rated filler around services
  • Unsealed penetrations discovered above suspended ceilings

For a school such as Sarisbury Infant School, penetration sealing fits best at the end of the summer works.

What your quote should include

  • What site paperwork they can supply
  • Which product they’ll use, and why it suits the joint
  • What level of public liability insurance do they hold?
  • What the guarantee covers, and for how long

Our contractor checklist

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Large openings beyond what any sealant detail covers
  • Approving the work on behalf of building control

If you are not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

What we seal

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

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Commercial clients in Sarisbury Green

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Sarisbury Green can sit alongside others in a wider programme.

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Maintenance after handover

A few simple habits keep the new joints working:

  • Foam or ordinary sealant is never a fire-seal repair
  • File the specified details where the next contractor can find them
  • Flag new cables with no seal around them
  • Get seals inspected before ceilings and boxing close

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and installation follows the programme.

Compartments and services around Sarisbury Green

At about 68 miles from central London, Sarisbury Green 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. 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. We install whatever has been specified, to the product’s tested detail.

On a site such as Park Gate Business Centre (1.4 miles north-east of Sarisbury Green), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Large healthcare estates like Fareham Community Hospital (0.9 miles north-east of Sarisbury Green) change their services often, so penetration seals are worth checking after M&E work.

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Several jobs near Sarisbury Green can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. First we go through the drawings, schedule or specification for the seals 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. 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. If an opening needs something other than sealant, we tell you instead of improvising.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work
  • Explain the parking and delivery arrangements

Questions we’re asked in Sarisbury Green

Can you work at a site such as Park Gate Business Centre, by Sarisbury Green?

Yes, sites like Park Gate Business Centre are within our area, along with the rest of Sarisbury Green. A few photos and the unit address let us price the work.

Would you work within a site like Fareham Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Do you seal openings left by new services?

Yes, where there is a specification for those walls and floors. New services after M&E works often breach existing seals and we close them with the specified product.

Will you write the fire-stopping specification?

No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Is fire stopping in Scotland covered by different guidance?

Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor.
