When to call us in Four Elms
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe and the opening isn’t always resealed.
Most enquiries start with something like this:
- Penetration schedules that need working through
- Open linear gaps along the top of fire-resisting walls
- Fire seals cut back for extra cables and never reinstated
- Builders’ foam or ordinary silicone in compartment walls
Hotels such as Hever Hotel, 1.5 miles to the south-east of Four Elms, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Fire stopping in Four Elms
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on linear gaps at wall heads, pipe penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are unsealed joints where partitions meet the slab and old intumescent sealant that has split away. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Four Elms is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a smaller site near Four Elms, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, phone 01277 525 020 or send photos by email and we will arrange a return visit.

FAQs: Four Elms
Do you seal service penetrations in hotels around Four Elms?
Yes, where the specification calls for fire-rated sealant. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Four Elms?
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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
What the job involves on each surface
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and any bundle too large for sealant alone is flagged.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.

After the work
Problems stay small when the joints are checked regularly. In particular:
- Agree the fire-stopping specification before services go in
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Include service cupboards in routine inspections
- Get seals inspected before ceilings and boxing close
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match.
Where services cross fire walls in Four Elms
Central London is about 21 miles from Four Elms. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. There are a number of hotels within about 2 miles of Four Elms. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
Halls and meeting rooms at places like Congregational Church sometimes gain new services, and any compartment wall crossed needs the specified seal. Hospital estates such as Edenbridge and District War Memorial Hospital (2.3 miles south-west of Four Elms) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

- Openings are measured and grouped by detail.

Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
