Fire stopping in Dragons Green
Facilities managers in Dragons Green often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. Most enquiries involve fire-stopping items raised at inspection or handover and non-fire-rated filler around services, across linear gaps at wall heads, joints between fire-resisting walls and floors and pipe penetrations. A specialist sealant contractor works differently from a general builder: in Dragons Green, that means joint design, primers and backing rod as standard.
Smaller places such as Dragons Green still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What the job involves on each surface
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically and tell you about openings outside the list.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Construction that lacks the fire resistance the seal relies on
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
What we seal
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations
Common problems we fix in Dragons Green
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.
Any of the following is a good reason to get the joints checked over:
- Open linear gaps along the top of fire-resisting walls
- Hidden openings found during inspections
- Unsealed openings around new pipes and cables
- Fire sealant pulled out of the opening
For a school such as Shipley CofE Primary School, penetration sealing fits best at the end of the summer works.

Common questions from Dragons Green clients
What does the BS 476 change mean for fire-rated sealant in Dragons Green?
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.
Is a hospital such as Horsham Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Do you work in Dragons Green?
Yes. We cover Dragons Green. To discuss a job, give us a call on 01277 525 020 or email a schedule or drawings.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Service penetrations in Dragons Green buildings
Dragons Green is about 37 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. 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.
Halls and meeting rooms at places like The Church of St Mary the Virgin sometimes gain new services, and any compartment wall crossed needs the specified seal. For a hospital such as Horsham Hospital (5.4 miles north-east of Dragons Green), penetration sealing is usually phased ward by ward, with infection-control rules agreed first.
Dragons Green is about 5 miles south-west of Horsham, in West Sussex. Dragons Green sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 373 places in West Sussex, large and small. Our Brighton page has more on work in that area (16 miles or so).

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally 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. If others near Dragons Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Tell us your opening times and when work is allowed
- Share the asbestos register for older buildings
- Move anything stored against the joints
