How we handle fire stopping in Malden Rushett
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. If you are dealing with open linear gaps along the top of fire-resisting walls and unsealed openings around new pipes and cables, we can put it right. Most enquiries from Malden Rushett start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Why deal with it now?
The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Surface by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Plastic pipes whose detail calls for a collar or wrap
- Signing off or certifying a building’s fire stopping
- Fire doors, dampers or other fire safety equipment
If you’re not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer before you book.
What we seal
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Pipe penetrations
- Cable penetrations
Maintenance after handover
A few simple habits keep the new joints working:
- Arrange inspection before areas are covered up
- Include service cupboards in routine inspections
- Foam or ordinary sealant is never a fire-seal repair
- Brief every trade that openings they make must be sealed
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.
Fire stopping in Malden Rushett: the local picture
A 2-mile radius around Malden Rushett takes in several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
Offices at parks like Silverglade Business Park (less than half a mile east of Malden Rushett) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Hospital estates such as West Park Hospital, 0.8 miles to the east of Malden Rushett, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

When to call us in Malden Rushett
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.
Typical triggers for a call:
- Openings found when ceilings come down for a refit
- Penetration schedules that need working through
- Service penetrations left open after M&E works
- Fire sealant pulled out of the opening
For a unit at a centre such as The Ashley Centre (2.2 miles east of Malden Rushett), penetration seals are worth checking after each shop fit.

Yes, sites like Silverglade Business Park are within our area, along with the rest of Malden Rushett. Photos and a short description are enough for a first look.
Is a hospital such as West Park Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Will you sign off the seals for us?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.
What do you charge?
There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is Malden Rushett in your area?
Yes. We take on work across Malden Rushett, with one number for every area we cover.
Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send 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.
- Foam, ordinary sealant and debris come out 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
- Flag any permit to work we’ll need
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
