Fire stopping for commercial buildings in Martin
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. The enquiries we see most involve unsealed joints where partitions meet the slab and penetration schedules that need working through, across pipe penetrations, service gaps in risers and cable penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Martin it comes down to the same thing: the right product in a properly prepared joint.
For a smaller site near Martin, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Different surfaces, different methods
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.
FAQs: Martin
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Martin?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Do you decide the fire-stopping details for buildings in Martin?
No, that sits with the designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
Can you work while the building is occupied?
Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.
On site: what to expect
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around Martin, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Send any specification or drawings in advance
- Make sure the joints can be reached
- Warn occupants and staff about the work

What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Deciding what a wall or floor needs, which belongs to the designer
- Construction that lacks the fire resistance the seal relies on
- Reviewing a building’s overall fire safety
If you are not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer.
Where we work in Martin

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
What we’re called out for in Martin
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position and has to be removed.
Common reasons buildings call us in:
- Unsealed joints where partitions meet the slab
- Expanding foam used as fire stopping
- Unsealed openings around new pipes and cables
- Unsealed penetrations discovered above suspended ceilings
Halls and meeting rooms at places like Church of All Saints sometimes gain new services, and any compartment wall crossed needs the specified seal.
What your quote should include
- Who will actually carry out the work
- Do they follow the manufacturer’s priming guidance?
- The named product and why it was chosen
- Their plan for phasing and protecting the area
Where services cross fire walls in Martin
In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Around Martin, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.
