Fire stopping near Botany Bay
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Fire stopping in Botany Bay
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. Those on your schedule are closed with the specified product. If you are dealing with fire sealant pulled out of the opening and hidden openings found during inspections, we can help, on cable penetrations, pipe penetrations and small duct penetrations where the tested detail allows alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Botany Bay it comes down to the same thing: 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. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions about Botany Bay
Can you work around term dates at a campus such as Oak Hill College?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Does your area include sites such as Sopers Road Industrial Estate, near Botany Bay?
Yes. Estates, retail parks and business parks around Botany Bay, Sopers Road Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Do you approve fire stopping for building control?
No. Approval sits with the designer, principal designer or building control. We will confirm the products and details used, and you can tell us what other records you need at quote stage.
Do you have third-party installer accreditation for fire stopping?
No, and we won’t imply otherwise. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Do you offer coloured sealant?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Compartment walls and floors in Botany Bay
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
For a job in Botany Bay, we confirm the ULEZ-compliant vehicle, the loading arrangements and where materials go before we arrive. Hospital estates such as Chase Farm Hospital, 1.2 miles south-east of Botany Bay, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Botany Bay is about 3 miles south-east of Potters Bar, in Greater London. We cover commercial sites throughout Botany Bay. Botany Bay is one of 764 places we cover in Greater London for service penetrations. London is covered too, some 12 miles away.

Site staff or a sealant specialist?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Fire doors, dampers or other fire safety equipment
- Issuing fire ratings or certificates for seals
- Writing the fire-stopping specification
If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
Surfaces we seal
- Service gaps in risers
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Linear gaps at wall heads
Common problems we fix in Botany Bay
Openings in fire-resisting walls usually appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
It’s worth sending us details if you spot any of the following:
- Openings found when ceilings come down for a refit
- Seals that don’t match their tested detail
- Open linear gaps along the top of fire-resisting walls
- Builders’ foam or ordinary silicone in compartment walls
Industrial units on estates such as Sopers Road Industrial Estate, 2.2 miles north of Botany Bay, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
What your quote should include
- Their public liability cover
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Health and safety accreditation such as CHAS
- Whether old or failed sealant will be cut out, not overlaid
Leave it or put it right?
Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
A quote for service penetrations depends on how many there are, their condition and the access. Ask us for a fixed quote.

Diagnose, treat, sign off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. In Botany Bay, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
- Move anything stored against the joints
