Doing it in-house
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. 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 West Grinstead
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. We work to the product’s tested detail for every seal. We work on pipe penetrations, cable penetrations and service gaps in risers, and the usual reasons a site gets in touch are openings found when ceilings come down for a refit and fire sealant pulled out of the opening. A specialist sealant contractor works differently from a general builder: on jobs in West Grinstead, preparation and product choice get the time they need.
For a smaller site near West Grinstead, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

What happens if it’s left?
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Around West Grinstead, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Questions we are asked in West Grinstead
Will you take on work at estates like Pondtail Farm (Business Park), close to West Grinstead?
Yes, sites like Pondtail Farm (Business Park) are within our area, along with the rest of West Grinstead. Photos and a short description are enough for a first look.
Is a smaller place like West Grinstead outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What we are called out for in West Grinstead
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in.
Things that usually lead to an enquiry:
- Seals that don’t match their tested detail
- Fire sealant pulled out of the opening
- Fire-stopping items raised at inspection or handover
- Non-fire-rated filler around services
For a building at a site such as Pondtail Farm (Business Park) (1.4 miles north-west of West Grinstead), a check of penetration seals after each fit-out is good practice.
Questions to ask before you book
- What level of public liability insurance do they hold?
- How long is the guarantee, and what does it include?
- Will CSCS-carded applicators be on site?
- Will failed sealant be removed rather than covered?

Fire stopping in West Grinstead: the local picture
Fire stopping of openings and penetrations in England falls under 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. Our part stays the same: the specified product, installed to its tested detail. At about 37 miles from central London, West Grinstead is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Older community buildings such as Shrine Church of Our Lady of Consolation and St Francis that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Honest limits
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Issuing fire ratings or certificates for seals
- Walls or floors that aren’t fire-resisting to begin with
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, call 01277 525 020 or email us and we’ll say what we think.
Surfaces we seal
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
Surface by surface
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers.
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
