Penetration seals near Romney Street
At about 18 miles from central London, Romney Street is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds 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. We install whatever has been specified, to the product’s tested detail.
For a hospital such as Sevenoaks Hospital, which lies south-west of Romney Street, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. For a building such as Church of Saint Mary the Virgin, new heating or data runs are the usual reason penetrations need sealing.

About our fire stopping in Romney Street
Facilities managers in Romney Street often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and cable penetrations, and the usual reasons a site gets in touch are fire-stopping items raised at inspection or handover and builders’ foam or ordinary silicone in compartment walls. For commercial sealant work in Romney Street, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Barn and farm-building conversions near places like Romney Street often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Signs you need fire stopping in Romney Street
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
If one of these sounds familiar, it’s time for a closer look:
- Expanding foam used as fire stopping
- Seals disturbed by maintenance and left open
- Seals that don’t match their tested detail
- Unsealed openings around new pipes and cables
For a unit at a site such as West Kingsdown Industrial Estate, which lies north-east of Romney Street, new power or data runs between office and warehouse can breach a compartment wall.
What your quote should include
- How joint depth will be controlled
- Can the work be phased to keep areas open?
- How the existing material will be dealt with
- Whether their applicators hold CSCS cards
Questions we’re asked in Romney Street
Is a hospital such as Sevenoaks Hospital somewhere you can work?
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 Romney Street?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
How much does the work cost?
Each job is quoted on its own details. For yours, ring 01277 525 020 or send photos by email.
Can the sealant be colour-matched?
It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
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 will confirm the curing time on the day.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Quoting for work in Romney Street
Each job is priced on its own details. The main factors are:
- How much existing material needs removing
- Location, for remote and island sites
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Whether an asbestos survey exists
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
- The product your specification calls for
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
What the job involves on each surface
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe. If the detail needs something beyond sealant, we tell you.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Writing the fire-stopping specification
- Issuing fire ratings or certificates for seals
- Fire risk assessments, a job for a competent assessor
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Pipe penetrations
