Fire stopping for commercial buildings in Bayswater
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. We work on small duct penetrations where the tested detail allows, cable penetrations and pipe penetrations, and what we’re called in for most is old intumescent sealant that has split away and open linear gaps along the top of fire-resisting walls. A specialist sealant contractor works differently from a general builder: on jobs in Bayswater, preparation and product choice get the time they need.
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.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- Induction, permit and paperwork requirements
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Any dates the work must fit around
- How the joints are reached, and at what height
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or send photos by email if you’d rather talk the job through.
Surface by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening.
Questions about Bayswater
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.
Do you cover business parks and estates near Bayswater, such as Stable Way Industrial Estate?
Yes, sites like Stable Way Industrial Estate are within our area, along with the rest of Bayswater. Photos and a short description are enough for a first look.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see and we close them with the specified product.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How long does a job like this take?
That varies with the scale of the job, though a typical visit typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we will set out a timescale with the quote.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months on every job.
Can you tell us what fire stopping our building needs?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

Fire stopping around Bayswater: how the place shapes the job
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. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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.
For a hospital such as St Mary's Hospital (1 mile north-east of Bayswater), penetration sealing is usually phased ward by ward, with infection-control rules agreed first. Industrial units on estates such as Stable Way Industrial Estate, 1.3 miles west of Bayswater, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. For an estates team at a campus like Brigham Young University London Centre, less than half a mile to the north of Bayswater, summer M&E works are usually followed by a round of penetration sealing.
Bayswater is about 1 mile north-east of Kensington, in Greater London. We cover commercial sites throughout Bayswater, for single jobs and planned programmes alike. Bayswater is one of 764 places we cover in Greater London for service penetrations.
We take on service penetrations across the W2, W8 and W11 postcode area, for business premises of every kind. Buildings on Dukes Lane, Salem Road and Aubrey Road are within our area for service penetrations. Bayswater sits on or close to the A4204 and A4206, which helps when planning parking and deliveries for the job. Sites close to Bayswater are covered too, including Westbourne (1 mile north), Westbourne Green (1 mile north), Little Venice (1 mile north-east), Paddington (1 mile north-east) and Paddington Green (1 mile north-east).

Commercial clients in Bayswater
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Tell us what induction or permit system the site runs
- Point out any areas we must not close
- Share your working hours and any access restrictions

What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Deciding what a wall or floor needs, which belongs to the designer
- Openings that need collars, wraps, batts or boards rather than sealant
- Gaps in walls that were never built as compartment walls
If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.
Joints and surfaces we work on
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Pipe penetrations
