Fire stopping near Allhallows-on-Sea

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

Quoting for work in Allhallows-on-Sea

These are the things that shape the price:

  • Joint width, depth and condition
  • How much existing material needs removing
  • Which sealant the job calls for
  • Quantities, in metres or numbers

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

However big the job, the same details help:

  • The product your specification calls for
  • The postcode of the building
  • Access details, including height
  • The type of building and who uses it

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email drawings and photos.

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, call 01277 525 020 or send details through our quote form with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. Most enquiries involve head-of-wall gaps with no fire seal and unsealed penetrations discovered above suspended ceilings, across linear gaps at wall heads, cable penetrations and pipe penetrations. Whoever orders the work in Allhallows-on-Sea, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Rural conversions around Allhallows-on-Sea can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Allhallows-on-Sea, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  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.

Before we start on site

  • Share your working hours and any access restrictions
  • Let us know about inductions and permits
  • Share the asbestos register for older buildings

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Where services cross fire walls in Allhallows-on-Sea

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. Central London is about 32 miles from Allhallows-on-Sea. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

Wherever services are added at a hospital such as Chartwell Private Hospital (to the north of Allhallows-on-Sea) the compartment line has to be made good with the specified product. Halls and meeting rooms at places like Church of All Saints sometimes gain new services, and any compartment wall crossed needs the specified seal.

Allhallows-on-Sea is about 4 miles south-east of Canvey Island, in Medway. We cover commercial sites throughout Allhallows-on-Sea, for single jobs and planned programmes alike. Allhallows-on-Sea is one of 54 places in Medway on our list. There’s a separate page for London, roughly 32 miles from Allhallows-on-Sea.

If you need fire stopping in ME3, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. We cover commercial and managed buildings on Avery Way, Queensway and Park End View and the roads nearby. Nearby places we also cover include Allhallows (1 mile south-west), Lower Stoke (1 mile south-west), Middle Stoke (2 miles south-west), Stoke (2 miles south-west) and St Mary Hoo (3 miles west) for service penetrations. Nearby towns on our patch include Gillingham (8 miles south-west), Chatham (10 miles south-west), Rochester (9 miles south-west), Rainham (8 miles south), Strood (9 miles south-west) and Luton (9 miles south-west).

Aftercare for building managers

A few simple habits keep the new joints working:

  • Flag new cables with no seal around them
  • Look above ceilings when tiles are lifted for other jobs
  • Arrange inspection before areas are covered up
  • Keep general-purpose fillers away from compartment walls

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.

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 instead of being left for someone else.

When to call us in Allhallows-on-Sea

Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

Typical triggers for a call:

  • Fire-rated sealant that has cracked or shrunk back
  • Improvised or mixed-product fire seals
  • Open linear gaps along the top of fire-resisting walls
  • Openings left by services added after handover

Holiday works at schools like Allhallows Primary Academy often leave service openings to seal before pupils return.

Allhallows-on-Sea: questions and answers

Can you take on a job at a hospital such as Chartwell Private 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.

How does the move away from BS 476 affect penetration seals in Allhallows-on-Sea?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Allhallows-on-Sea can sit alongside others in a wider programme.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Writing the fire-stopping specification
  • Walls or floors that aren’t fire-resisting to begin with

If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.

What we seal

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