Common questions from Ratling clients

Is Aylesham Industrial Estate, near Ratling, within your area?

Yes, sites like Aylesham Industrial Estate are within our area, along with the rest of Ratling. Send details of the unit and the work through our quote form for a quick quote.

What does the BS 476 change mean for fire-rated sealant in Ratling?

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.

How long do sealant joints last?

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 inspection is the best way to catch problems early.

Can you work while the building is occupied?

Typically, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member.

About our fire stopping in Ratling

No fire sealant works on its own: 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 have old intumescent sealant that has split away and seals disturbed by maintenance and left open, we can help, on cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads alike. One point of contact handles commercial sealant work in Ratling from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Barn and farm-building conversions near places like Ratling often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Large openings beyond what any sealant detail covers
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire risk assessments, a job for a competent assessor

Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly.

Joints and surfaces we work on

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

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

What we are called out for in Ratling

Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.

These are often picked up first by site or facilities staff:

  • Fire sealant pulled out of the opening
  • Fire-stopping items raised at inspection or handover
  • Hidden openings found during inspections
  • Expanding foam used as fire stopping

On estates like Aylesham Industrial Estate, which lies south-west of Ratling, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Do they follow the manufacturer’s priming guidance?
  • How long is the guarantee, and what does it include?
  • The named product and why it was chosen

Choosing a commercial sealant contractor

Fire stopping around Ratling: what changes locally

Ratling is about 59 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. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail.

Halls and meeting rooms at places like St Peter sometimes gain new services, and any compartment wall crossed needs the specified seal. Holiday works at schools like St Joseph's Catholic Primary School often leave service openings to seal before pupils return.

Ratling is about 6 miles south-east of Canterbury, in Kent. Anywhere in CT3, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Ratling is one of 931 places in Kent on our list for service penetrations. We also cover London, some 59 miles away.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If others near Ratling need work, visits can be combined. You will have a fixed quote before work starts.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned 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.

What we need from you

  • Let building users know which areas are affected
  • Flag any permit to work we’ll need
  • Point out parking and an unloading spot

Advice

Building owners, agents and FMs in Ratling

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Ratling can form part of a wider programme across Kent.

Why deal with it now?

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. Halls, stores and units around places like Ratling may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why us?

  • Health and safety: CHAS accredited
  • Clear, fixed quotes
