Fire stopping for Bobbing sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What sets the cost

These are the things that shape the price:

  • Induction, permit and paperwork requirements
  • How much there is to seal
  • Whether the work must be split into stages
  • Removal of failed or old sealant

The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • Approximate linear metres or a joint schedule
  • A wide shot and a close-up of the area
  • What the building is and how it’s used
  • Specification clauses that apply

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

Fire stopping in Bobbing

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths 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. If you’re dealing with expanding foam used as fire stopping and seals that don’t match their tested detail, we can put it right, on joints between fire-resisting walls and floors, service gaps in risers and pipe penetrations alike. A single leaking joint is often how a building in Bobbing first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a smaller site near Bobbing, we plan to do all the penetrations in one go, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Fire-rated sealing for Bobbing buildings

There are a number of hotels within about 2 miles of Bobbing. 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. In England, Approved Document B covers fire stopping of openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.

Colleges such as Sittingbourne College, 1.3 miles to the south-east of Bobbing, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Theatres, wards and plant rooms at sites like Sittingbourne Memorial Hospital (1.9 miles south-east of Bobbing) all have compartment walls crossed by services.

Bobbing is about 2 miles west of Sittingbourne, in Kent. Our applicators travel to Bobbing for work on service penetrations, handled exactly as we handle every other area. 931 places across Kent fall within our area, Bobbing among them. There’s a separate page for London, about 36 miles away.

Anyone looking for fire stopping in ME9 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Streets here include Bobbing Hill, Cold Harbour Lane and Ladyfields Close, and sites on any of them can send details for a fixed quote. If your building is just outside Bobbing, we cover Keycol (1 mile west), Chestnut Street (1 mile south-west), Danaway (1 mile south-west), Newington (1 mile west) and Oad Street (2 miles south-west). Nearby towns on our patch include Maidstone (9 miles south-west), Gravesend (15 miles west), Whitstable (14 miles east), Faversham (8 miles east), Minster (7 miles north-east) and Kings Hill (14 miles south-west).

How the job changes by surface

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, along the full length of the run.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.

Questions about Bobbing

Will you plan work around the academic year at somewhere like Sittingbourne College?

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 take on work at healthcare sites like Sittingbourne Memorial Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

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.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

What will the job cost?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Maintenance after handover

For the best life from the joints:

  • File the specified details where the next contractor can find them
  • Arrange inspection before areas are covered up
  • Keep general-purpose fillers away from compartment walls
  • Flag new cables with no seal around them

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. 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 Bobbing can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Send any specification or drawings in advance
  • Agree which areas must stay open
  • Share the asbestos register for older buildings

Advice

Common problems we fix in Bobbing

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in and later need putting right.

Clients usually get in touch after noticing something like this:

  • Openings found when ceilings come down for a refit
  • Seals disturbed by maintenance and left open
  • Head-of-wall gaps with no fire seal
  • Builders’ foam or ordinary silicone in compartment walls

In a building such as Church of St Bartholomew, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • How they’ll work around occupants
  • What site paperwork they can supply
  • How long is the guarantee, and what does it include?
