Fire stopping for commercial buildings in Martins Heron
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. The enquiries we see most involve fire sealant pulled out of the opening and unsealed openings around new pipes and cables, on cable penetrations, pipe penetrations and joints between fire-resisting walls and floors. A specialist sealant contractor works differently from a general builder: on jobs in Martins Heron, preparation and product choice get the time they need.
In places the size of Martins Heron, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
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 spell out the cover before we begin.

Surface by surface
Risers and ceiling voids

Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness first.
Fire-rated sealing for Martins Heron buildings
Martins Heron sits in or beside Bracknell, a twentieth-century planned town. Decades of new cabling and pipework in planned-town buildings can leave openings in compartment walls to seal with the specified product. The area within 2 miles of Martins Heron holds a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
Hospital estates such as Heatherwood Hospital, 1.6 miles east of Martins Heron, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For an estates team at a campus like Imperial College Silwood Park Campus, 3.3 miles east of Martins Heron, summer M&E works are normally followed by a round of penetration sealing.
Martins Heron is about 1 mile east of Bracknell, in Bracknell Forest. Across the RG12 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

When to call us in Martins Heron
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access typically bring them to light.
Look out for the following:
- Fire stopping installed outside its tested range
- Unsealed penetrations discovered above suspended ceilings
- Non-fire-rated filler around services
- Service penetrations left open after M&E works
Hotels such as The Royal Foresters Hotel (0.7 miles east of Martins Heron) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
What to look for in a quote

Common questions from Martins Heron clients
What does the BS 476 change mean for fire-rated sealant in Martins Heron?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is a smaller place like Martins Heron outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Do you guarantee your work?
Yes. Workmanship is guaranteed for 12 months on every job.
How do you deal with asbestos in old sealant?
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 come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How do I request a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or use the quote form. Include photographs or drawings if you have them.

Keeping the joints sound
After handover, a little attention goes a long way:
- Check with the data sheet before painting over fire sealant
- Flag new cables with no seal around them
- Get seals inspected before ceilings and boxing close
- Foam or ordinary sealant is never a fire-seal repair
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and our waste is bagged and taken away as we go. Work in places the size of Martins Heron is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Share your working hours and any access restrictions
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Gaps in walls that were never built as compartment walls
- Openings that need collars, wraps, batts or boards rather than sealant
- Signing off or certifying a building’s fire stopping
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly.
Joints and surfaces we work on
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
