Fire stopping for businesses in Langton Green

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

Doing it in-house

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

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.

How we handle fire stopping in Langton Green

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on joints between fire-resisting walls and floors, service gaps in risers and cable penetrations, and the usual reasons a site gets in touch are service penetrations left open after M&E works and improvised or mixed-product fire seals. A single leaking joint is often how a building in Langton Green first comes to us: we look at the rest while we are there and tell you what we find.

Around smaller places like Langton Green, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Where services cross fire walls in Langton Green

Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail. The area within 2 miles of Langton Green holds a good number of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

Older community buildings such as Church of All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Hotels such as The Spa Hotel (to the east of Langton Green) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Langton Green is about 2 miles west of Royal Tunbridge Wells, in Kent. Langton Green sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Langton Green is one of 931 places we cover in Kent. Our Brighton page has more on work in that area (26 miles or so).

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Approving the work on behalf of building control
  • Fire risk assessments, a job for a competent assessor
  • Deciding what a wall or floor needs, which belongs to the designer

Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly before you book.

Where we work in Langton Green

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

What affects the price in Langton Green

Each job is priced on its own details. The things that drive the figure:

  • The product specified
  • The site’s rules and procedures
  • Distance, for remote addresses
  • Working within restricted access windows

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Approximate linear metres or a joint schedule
  • Clear photographs of the problem areas
  • Asbestos survey details if the building is older
  • Any dates the work must fit around

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or send photos by email.

Common problems we fix in Langton Green

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

Clients usually get in touch after noticing one or more of the following:

  • Old intumescent sealant that has split away
  • Open linear gaps along the top of fire-resisting walls
  • Hidden openings found during inspections
  • Non-fire-rated filler around services

For a building at a site such as Speldhurst Business Park, 0.9 miles north of Langton Green, a check of penetration seals after each fit-out is good practice.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their pre-qualification and accreditations
  • Is the sealant right for the movement and the substrate?
  • Do they follow the manufacturer’s priming guidance?

How to choose a sealant contractor

Langton Green: questions and answers

Would you work within a site like Tunbridge Wells Nuffield Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Langton Green too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is the BS 476 change in 2029 relevant to fire stopping?

From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, subject to the Government’s transitional arrangements. The European route, BS EN 13501-2, then applies. Product selection stays with your designer.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Are you fully insured?

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

Do you guarantee your work?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. If neighbouring businesses or buildings around Langton Green need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  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. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Agree which areas must stay open
  • Let us know about inductions and permits
  • Have the specification and drawings to hand
