Signs you need fire stopping in Hawthorn

Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.

Things that normally lead to an enquiry:

  • Unsealed openings around new pipes and cables
  • Unsealed joints where partitions meet the slab
  • Damaged fire seals in risers and voids
  • Expanding foam used as fire stopping

Theatres, wards and plant rooms at sites like Queen Victoria Memorial Hospital (to the west of Hawthorn) all have compartment walls crossed by services.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Do they follow the manufacturer’s priming guidance?
  • Their public liability cover
  • Whether their applicators hold CSCS cards

Our contractor checklist

About our fire stopping in Hawthorn

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal. Site teams most often ask us about non-fire-rated filler around services and fire-stopping items raised at inspection or handover, across pipe penetrations, linear gaps at wall heads and cable penetrations. A specialist sealant contractor works differently from a general builder: on jobs in Hawthorn, preparation and product choice get the time they need.

Smaller places such as Hawthorn 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.

Every job we finish is backed by a 12-month workmanship guarantee, in Hawthorn as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Where services cross fire walls in Hawthorn

Central London is about 56 miles from Hawthorn. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Two care or nursing homes sit less than 2 miles from Hawthorn. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail.

For a building at a site such as Eddington Business Park (2.2 miles west of Hawthorn), a check of penetration seals after each fit-out is good practice. In a school such as Reculver Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Hawthorn is about 2 miles east of Herne Bay, in Kent. Commercial clients in Hawthorn can call on us for service penetrations, as part of our coverage of Kent. Our Kent coverage takes in 931 places. London is covered too, around 56 miles from Hawthorn.

Postcode districts covered here: CT6 and CT3. We cover commercial and managed buildings on Campion Avenue, Sweechbridge Road and Heart in Hand Road and the roads nearby.

Questions we are asked in Hawthorn

Can you take on a job at a hospital such as Queen Victoria Memorial Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Hawthorn too small for you to travel to?

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.

What will the job cost?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or send photos by email with a description of the work.

Do you work in Scotland as well as England?

Building standards in Scotland are separate from England’s, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.

Do you certify or sign off fire stopping?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Are you members of a third-party fire-stopping installer scheme?

No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we will say so right away rather than waste your time.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Issuing fire ratings or certificates for seals
  • Gaps in walls that were never built as compartment walls
  • Reviewing a building’s overall fire safety

If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer.

Joints and surfaces we work on

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

Aftercare for building managers

A few simple habits keep the new joints working:

  • Keep product data and details in the fire safety file
  • Look above ceilings when tiles are lifted for other jobs
  • Report damaged or disturbed seals as soon as they’re spotted
  • Check with the data sheet before painting over fire sealant

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

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.

Why it’s worth doing now in Hawthorn

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Older rural buildings around Hawthorn move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Why us?

  • CSCS-carded applicators
  • Sealing commercial buildings since 2005
  • Products installed to the manufacturer’s instructions

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Hawthorn, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First we confirm the product and tested details named in the specification.
  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. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Let us know about inductions and permits
  • Arrange parking or a loading space
  • Tell staff and tenants when we’ll be in

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.

Owners, agents and contractors
