Questions we’re asked in Headcorn
Do you take on work at healthcare sites like Benenden Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
What happens to BS 476 references for fire stopping in Headcorn?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What if there’s asbestos in the old mastic?
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 work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
What will the job cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
How do we ask for a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.
Fire stopping for commercial buildings in Headcorn
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Headcorn. We work on linear gaps at wall heads, pipe penetrations and service gaps in risers, and the usual reasons a site gets in touch are unsealed openings around new pipes and cables and snag lists that include open service penetrations. Searching for sealant specialists in Headcorn? We have been sealing commercial buildings since 2005.
In places the size of Headcorn, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Every job we finish is backed by a 12-month workmanship guarantee, in Headcorn as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Openings that need collars, wraps, batts or boards rather than sealant
- Approving the work on behalf of building control
- Fire risk assessments, a job for a competent assessor
If you are not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer.
Surfaces we seal
- Linear gaps at wall heads
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Pipe penetrations

On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. What matters most for a job in Headcorn is a clear list of what needs doing. A fixed quote follows.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Point out parking and an unloading spot
- Point out any areas we must not close
- For older buildings, check the asbestos register before work

Advice
How the quote is worked out
To price the job, we consider:
- Whether old sealant has to be cut out first
- Quantities, in metres or numbers
- Whether the work must be split into stages
- Access and working height
A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
Details that help us quote
A few photos plus some basic facts will normally do. It helps to include:
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
- The postcode of the building
- Any specification or named product
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
Fire stopping around Headcorn: how the place shapes the job
Headcorn is about 39 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail.
Hospital estates such as Benenden Hospital (to the south of Headcorn) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a unit at a site such as Barradale Farm Industrial Estate, which lies north-west of Headcorn, new power or data runs between office and warehouse can breach a compartment wall. Schools such as Headcorn Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Different surfaces, different methods
Risers and ceiling voids
Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.
