Fire stopping across Upper Halliford

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

How we handle fire stopping in Upper Halliford

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve fire-stopping items raised at inspection or handover and seals disturbed by maintenance and left open, on joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows. Facilities teams, main contractors and managing agents in Upper Halliford 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 Upper Halliford is usually planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

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

How the job changes by surface

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Share these points with them:

  • File the specified details where the next contractor can find them
  • Flag new cables with no seal around them
  • Foam or ordinary sealant is never a fire-seal repair
  • Arrange inspection before areas are covered up

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original, or a new specification from the designer.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.

When to call us in Upper Halliford

When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.

It’s worth sending us details if you spot any of the following:

  • Service penetrations left open after M&E works
  • Openings found when ceilings come down for a refit
  • Improvised or mixed-product fire seals
  • Fire-rated sealant that has cracked or shrunk back

For a building at a site such as Longwood Business Park, 0.6 miles to the south-east of Upper Halliford, a check of penetration seals after each fit-out is good practice.

Questions to ask before you appoint anyone

Leave it or put it right?

The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. One visit to deal with every failing joint makes more sense than several trips to a place like Upper Halliford. Send photos of each area and we will quote for the lot.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Why us?

  • Sealing commercial buildings since 2005
  • One contact handling all your sites

Your questions answered

Can work at a site such as St Mary's University fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you seal service penetrations in hotels around Upper Halliford?

Yes, where the specification calls for fire-rated sealant. Each seal follows the tested detail, and rooms are done in turn.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can staff carry on working while you are here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

What do you charge?

Every job gets its own fixed quote. To get one, ring 01277 525 020 or email the details over.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be 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 brings efficiency, a consistent finish and a 12-month guarantee.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Upper Halliford are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work
  • Make sure the joints can be reached
