FAQs: Brompton
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Brompton?
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.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
What will the job cost?
Every job gets its own fixed quote. To get one, speak to us on 01277 525 020 or send details through our quote form.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
How we handle fire stopping in Brompton
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. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Brompton. If you are dealing with seals that don’t match their tested detail and fire-rated sealant that has cracked or shrunk back, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Brompton is the same: the right product in a properly prepared joint.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What sets the cost
What shapes the price:
- How accessible the joints are
- Travel to remote or island sites
- Which sealant the job calls for
- Removal of failed or old sealant
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- The type of building and who uses it
- Photos of the joints, close up and from further back
- Drawings or a marked-up plan, if available
- The postcode of the building
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email the details over.
How the job changes by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any that don’t are flagged.
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Let us know about inductions and permits
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000

When it isn’t the sealant
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Reviewing a building’s overall fire safety
- Writing the fire-stopping specification
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think.
Joints and surfaces we work on
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
Why it’s worth doing now in Brompton
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. In Brompton, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What you get with us
- One number for every site we cover
- A fixed quote before work starts
- Over 20 years of commercial sealing
- 12-month guarantee on workmanship

Fire stopping in Brompton: the local picture
The area within 2 miles of Brompton holds a good number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
For a unit at a site such as Brompton Cross District Shopping Centre., under half a mile west of Brompton, any new service through a fire-resisting wall should be sealed to the tested detail. Colleges such as St Mellitus Theological College (to the west of Brompton) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. For a hotel such as The Beaufort Hotel (under half a mile north of Brompton), penetration seals are worth checking after any refit or services upgrade.
