Fire stopping in South Stoke, done properly

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. We work on pipe penetrations, service gaps in risers and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are snag lists that include open service penetrations and openings found when ceilings come down for a refit. Looking for mastic applicators who cover South Stoke? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Smaller places such as South Stoke still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Settle who seals which penetrations at the start of a project
  • Foam or ordinary sealant is never a fire-seal repair
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Treat an open penetration as a priority repair

During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near South Stoke may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  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.

Preparing the site

  • Let us know about inductions and permits
  • Warn occupants and staff about the work
  • Have the specification and drawings to hand

Your questions answered

Is South Stoke off your patch?

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

Can you seal penetrations in a hotel in South Stoke after a refit?

Yes, where the specification calls for fire-rated sealant. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

When is resealing likely to be due?

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 checks let you plan resealing before leaks or damage.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Service penetrations in South Stoke buildings

A 2-mile radius around South Stoke takes in a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. South Stoke is about 45 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.

Older community buildings such as Church of St Andrew that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Holiday works at schools like South Stoke Primary School often leave service openings to seal before pupils return.

South Stoke is about 6 miles south-east of Didcot, in Oxfordshire. We cover commercial sites throughout South Stoke. 423 places across Oxfordshire fall within our area, South Stoke among them. Reading is covered too, around 10 miles from South Stoke.

Should maintenance staff do it?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What the job involves on each surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance.

When something else is needed

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

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Gaps in walls that were never built as compartment walls
  • Fire doors, dampers or other fire safety equipment

If in doubt, phone 01277 525 020 or send photos by email and we will say what we think before you book.

Joints and surfaces we work on

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

Why deal with it now?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Converted and older buildings near places like South Stoke tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
