About our fire stopping in Snowdown

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, give us a call on 01277 525 020 or email us with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and openings left by services added after handover, on cable penetrations, service gaps in risers and joints between fire-resisting walls and floors. A specialist sealant contractor works differently from a general builder: in Snowdown, that means joint design, primers and backing rod as standard.

Around smaller places like Snowdown, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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

Compartments and services around Snowdown

For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Central London is about 60 miles from Snowdown. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.

Holiday works at schools like St Joseph's Catholic Primary School often leave service openings to seal before pupils return. In a building such as St Peter, any service penetration through a fire-resisting wall should be sealed to the specified detail. Industrial units on estates such as Aylesham Industrial Estate, 0.9 miles to the north-west of Snowdown, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Snowdown is about 7 miles north-west of Dover, in Kent. Commercial clients in Snowdown use us for work on service penetrations, as part of our coverage of Kent. Snowdown is one of 931 places we cover in Kent. Sites around London have their own page, roughly 60 miles from Snowdown.

Anyone looking for fire stopping in CT15 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. For a building on The Crescent, South Avenue and Weston Mews or nearby, send details and we will quote for service penetrations. Sites close to Snowdown are covered too, including Nonington (1 mile north-east), Woolage Village (1 mile south-west), Frogham (1 mile south-east), Ratling (1 mile north) and Barfrestone (2 miles south-east). A short drive away, we cover Canterbury (7 miles north-west), Margate (14 miles north-east), Dover (7 miles south-east), Folkestone (9 miles south), Ramsgate (12 miles north-east) and Broadstairs (14 miles north-east).

Honest limits

Honesty saves time and money. New sealant won’t cure:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Issuing fire ratings or certificates for seals
  • Construction that lacks the fire resistance the seal relies on

If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think.

Joints and surfaces we work on

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

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • Access and working height
  • The product specified
  • Phasing around occupants
  • Whether old sealant has to be cut out first

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • When you need the work done
  • The product your specification calls for
  • The site address and postcode
  • A wide shot and a close-up of the area

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Common questions from Snowdown clients

Is Snowdown off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Snowdown?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How much does the work cost?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

After the work

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Record which product was used where
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Agree the fire-stopping specification before services go in
  • Have penetrations checked while they can still be seen

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 report them promptly.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

From enquiry to sign-off

Tell us your site hours and access windows and we’ll plan around them. 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 Snowdown can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  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. 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. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Tell us your opening times and when work is allowed
  • Explain the parking and delivery arrangements
