Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping in Slaugham
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance in Slaugham and nearby. If you have fire sealant pulled out of the opening and head-of-wall gaps with no fire seal, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Slaugham, that means joint design, primers and backing rod as standard.
A job near Slaugham is typically planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Common questions from Slaugham clients
Do you take on work at healthcare sites like Crawley Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Slaugham too small for you to travel to?
No. Places such as Slaugham are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
How the job changes by surface
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 before sealing.
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 and we confirm each before sealing.
Fire stopping around Slaugham: points for this area
At about 32 miles from central London, Slaugham is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Either way, we install the specified product to its tested detail.
For a building such as St Mary's Church, new heating or data runs are the usual reason penetrations need sealing. At a healthcare site like Crawley Hospital, 5.4 miles north of Slaugham, new services through compartment walls are a constant, and each needs the specified seal.

Common problems we fix in Slaugham
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.
Common reasons buildings call us in:
- Hidden openings found during inspections
- Expanding foam used as fire stopping
- Fire seals cut back for extra cables and never reinstated
- Openings left by services added after handover
For a school such as Warninglid Primary School, penetration sealing fits best at the end of the summer works.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Issuing fire ratings or certificates for seals
- Large openings beyond what any sealant detail covers
- Reviewing a building’s overall fire safety
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly.
What we seal
- Pipe penetrations
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
Why act early in Slaugham
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Halls, stores and units around places like Slaugham may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Advice
Looking after the joints
Once the work is signed off, these steps help:
- Put resealing into every M&E and fit-out package
- Arrange inspection before areas are covered up
- Check risers and ceiling voids after each round of works
- Leave fire sealant to cure fully before covering it
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
