What we need to price the job
Diagnosis starts before we arrive. Tell us:
- Where the site is, with the postcode
- Whether the building will be occupied during the work
- Access details, including height
- A wide shot and a close-up of the area
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
How we handle fire stopping in Lympne
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in. Most enquiries involve seals that don’t match their tested detail and unsealed joints where partitions meet the slab, on linear gaps at wall heads, joints between fire-resisting walls and floors and service gaps in risers. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lympne is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Smaller places such as Lympne still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

From enquiry to sign-off
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Rural sites near Lympne may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- 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.
- Where the detail needs backing, it goes in at the stated depth.
- 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.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Point out any areas we must not close

General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Common questions from Lympne clients
Do you decide the fire-stopping details for buildings in Lympne?
No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.
What happens to BS 476 references for fire stopping in Lympne?
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.
What do you charge?
Each job is quoted on its own details. For yours, call 01277 525 020 or use the quote form with a description of the work.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.
Compartments and services around Lympne
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. Our part stays the same: the specified product, installed to its tested detail. Central London is about 57 miles from Lympne. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.
In a school such as Lympne Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified. Older community buildings such as Church of St Stephen that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Commercial clients in Lympne
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Lympne can form part of a wider programme.
Maintenance after handover
For the best life from the joints:
- Foam or ordinary sealant is never a fire-seal repair
- Brief every trade that openings they make must be sealed
- Arrange inspection before areas are covered up
- Check risers and ceiling voids after each round of works
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Issuing fire ratings or certificates for seals
- Plastic pipes whose detail calls for a collar or wrap
- Writing the fire-stopping specification
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
