Fire stopping for commercial buildings in Rusthall

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. The enquiries we see most involve old intumescent sealant that has split away and open linear gaps along the top of fire-resisting walls, across cable penetrations, service gaps in risers and joints between fire-resisting walls and floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Rusthall, preparation and product choice get the time they need.

Around smaller places like Rusthall, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. 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.

Our workmanship is guaranteed for 12 months, in Rusthall as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Penetration seals near Rusthall

At about 29 miles from central London, Rusthall is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. Two care or nursing homes sit less than 2 miles from Rusthall. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.

For a building such as St Paul's Church Centre, new heating or data runs are the usual reason penetrations need sealing. Campus buildings at universities such as Canterbury Christ Church University - Salomons, 1.2 miles to the north-east of Rusthall, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Rusthall is about 2 miles west of Royal Tunbridge Wells, in Kent. We cover Rusthall, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Kent, 931 places are covered, Rusthall among them. There’s a separate page for Brighton, roughly 26 miles from Rusthall.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If neighbouring businesses or buildings around Rusthall need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Arrange parking or a loading space
  • Let us know about inductions and permits
  • Tell us your opening times and when work is allowed

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Signs you need fire stopping in Rusthall

Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access typically bring them to light.

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

  • Old intumescent sealant that has split away
  • Hidden openings found during inspections
  • Unsealed openings around new pipes and cables
  • Fire seals cut back for extra cables and never reinstated

Office fit-outs on sites such as Speldhurst Business Park (to the north-west of Rusthall) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

  • Their plan for phasing and protecting the area
  • Their public liability cover
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

Different surfaces, different methods

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.

Commercial clients in Rusthall

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Rusthall can form part of a wider programme.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Leave fire sealant to cure fully before covering it
  • Agree the fire-stopping specification before services go in
  • Check risers and ceiling voids after each round of works
  • Make fire stopping part of every scope that crosses a fire-resisting wall

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, by someone who knows the system.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Questions about Rusthall

Is Rusthall off your patch?

Not at all. Rusthall is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Is a hospital such as Tunbridge Wells Nuffield Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Will you write the fire-stopping specification?

No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months.
