About our fire stopping in Basted
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you have unsealed penetrations discovered above suspended ceilings and snag lists that include open service penetrations, we can help. Searching for sealant specialists in Basted? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For a smaller site near Basted, 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.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

What the job involves on each surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Signing off or certifying a building’s fire stopping
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Surfaces we seal
- Linear gaps at wall heads
- Service gaps in risers
- Pipe penetrations
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors

What happens to BS 476 references for fire stopping in Basted?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Penetration seals near Basted
At about 23 miles from central London, Basted is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. For England, the fire stopping of penetrations is dealt with in 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. What we install is set by the specification, and it goes in to the tested detail.
At a healthcare site like Sevenoaks Hospital, 4.8 miles west of Basted, new services through compartment walls are a constant, and each needs the specified seal. In a building such as The Church of the Good Shepherd, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
What sets the cost
To price the job, we consider:
- The product specified
- Any access equipment needed
- Site requirements such as inductions and permits
- Phasing around occupants
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- The site address and postcode
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email drawings and photos.
When to call us in Basted
Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Look out for the following:
- Fire seals cut back for extra cables and never reinstated
- Openings left by services added after handover
- Improvised or mixed-product fire seals
- Builders’ foam or ordinary silicone in compartment walls
Tenant changes at parks like Bourne Enterprise Centre (1 mile north of Basted) bring new data and services, and openings through fire-resisting walls need the specified seal.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- How they handle RAMS and site documents
- Proof of insurance
- Whether their applicators hold CSCS cards
