Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
On site: what to expect
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like Teston are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- 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.
Before we start on site
- Tell us your opening times and when work is allowed
- Arrange parking or a loading space
- Share the asbestos register for older buildings

About our fire stopping in Teston
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations, and the usual reasons a site gets in touch are seals that don’t match their tested detail and non-fire-rated filler around services. Searching for sealant specialists in Teston? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
For a smaller site near Teston, we plan to do all the penetrations in one go, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Fire stopping around Teston: how the place shapes the job
Central London is about 29 miles from Teston. Office refits around the commuter belt bring new cabling through fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Workshops and IT rooms at colleges like MidKent College Maidstone Campus, 2.5 miles to the east of Teston, are re-serviced often, leaving penetrations to seal. Tenant changes at parks like Mereworth Business Centre (to the west of Teston) bring new data and services, and openings through fire-resisting walls need the specified seal.
Teston is about 4 miles west of Maidstone, in Kent. Any commercial site in Teston is covered, whether it’s a single job or part of a planned programme. We work across 931 places in Kent. We also cover London, around 29 miles from Teston.

Nearby places we also cover include Red Hill (1 mile north-west), West Farleigh (1 mile south-east), Wateringbury (1 mile west), Barming Heath (1 mile east) and Hoppers Corner (1 mile east) for service penetrations.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Fire doors, dampers or other fire safety equipment
- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Pipe penetrations
- Linear gaps at wall heads
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Joints between fire-resisting walls and floors
Your questions answered
Do you take on work at healthcare sites like Maidstone Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What does the BS 476 change mean for fire-rated sealant in Teston?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
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. Work pauses if suspect material is found, until it has been tested.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Is Teston in your area?
Yes. Teston is in our area and the rest of Kent. To discuss a job, speak to us on 01277 525 020 or send details through our quote form.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.

What sets the cost
The price varies from site to site. Expect it to depend on:
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
- The product specified
- The size and state of each joint
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
What to include in your enquiry
Good information means a firmer quote. Helpful details to send:
- Photos of the joints, close up and from further back
- The postcode of the building
- Anything awkward about access or site hours
- Any dates the work must fit around
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Building owners and managing agents use us on everything from one building to a spread of sites around Teston. Several sites can go on one quote, so there’s one set of paperwork to deal with.
What we are called out for in Teston
Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access usually bring them to light.
Typical triggers for a call:
- Snag lists that include open service penetrations
- Seals that don’t match their tested detail
- Open linear gaps along the top of fire-resisting walls
- Fire-rated sealant that has cracked or shrunk back
Wherever services are added at a hospital such as Maidstone Hospital (2.3 miles north-east of Teston) the compartment line has to be made good with the specified product.
What to look for in a quote
- Whether primer will be used where the manufacturer specifies it
- Proof of insurance
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
