How we handle fire stopping in Chelsea Harbour
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. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. If you have improvised or mixed-product fire seals and openings left by services added after handover, we can help, whatever the surface. Whoever orders the work in Chelsea Harbour, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
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.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Keep general-purpose fillers away from compartment walls
- Look above ceilings when tiles are lifted for other jobs
- Flag new cables with no seal around them
- Make fire stopping part of every scope that crosses a fire-resisting wall
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.
When to call us in Chelsea Harbour
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.
Most enquiries start with one or more of the following:
- Head-of-wall gaps with no fire seal
- Fire-rated sealant that has cracked or shrunk back
- Hidden openings found during inspections
- Expanding foam used as fire stopping
In a retail centre such as Brompton Cross District Shopping Centre., 1.4 miles to the north-east of Chelsea Harbour, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

Common questions from Chelsea Harbour clients
How does the move away from BS 476 affect penetration seals in Chelsea Harbour?
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.
Do you seal service penetrations in hotels around Chelsea Harbour?
Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Issuing fire ratings or certificates for seals
- Fire doors, dampers or other fire safety equipment
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, phone 01277 525 020 or email the details over and we will say what we think.

How a job runs
We follow your site rules from the start: 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. 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.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Warn occupants and staff about the work
- Move anything stored against the joints
- Tell us which areas need to stay in use

Advice
Why act early in Chelsea Harbour
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Getting scaffold, permits or access booked in Chelsea Harbour takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why appoint us

Fire stopping in Chelsea Harbour: the local picture
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. Either way, we install the specified product to its tested detail. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
Hospital estates such as Chelsea and Westminster Hospital, 0.6 miles north of Chelsea Harbour, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Residences at universities like Royal College of Art, 0.6 miles to the north-east of Chelsea Harbour, have compartment walls that must be resealed whenever services change.
