Fire stopping for Dagenham sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
About our fire stopping in Dagenham
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Dagenham and nearby. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations, and the usual reasons a site gets in touch are fire stopping installed outside its tested range and fire seals cut back for extra cables and never reinstated. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Dagenham, that means joint design, primers and backing rod as standard.
In a London area such as Dagenham, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

On site: what to expect
Occupied buildings need a little choreography. 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. All of Greater London is in the ULEZ, and kerbside space in Dagenham can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000
Ask for a quote
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 email drawings and photos to discuss it first.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Include service cupboards in routine inspections
- Put resealing into every M&E and fit-out package
- File the specified details where the next contractor can find them
- Don’t let anyone top up a fire seal with the wrong product
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.
FAQs: Dagenham
What does the BS 476 change mean for fire-rated sealant in Dagenham?
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.
Does your area include sites such as Merrielands Retail Park, near Dagenham?
Yes. We cover Dagenham and the area around it, including industrial estates, business parks and retail parks such as Merrielands Retail Park. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Are you insured?
Yes. We are fully insured, including public liability cover.
Do you offer coloured sealant?
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 will confirm the colours available for the specified product.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Signing off or certifying a building’s fire stopping
- Plastic pipes whose detail calls for a collar or wrap
- Writing the fire-stopping specification
If you’re not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Where we work in Dagenham
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
Why it’s worth doing now in Dagenham
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Fire stopping around Dagenham: points for this area
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. We install whatever has been specified, to the product’s tested detail. A 2-mile radius around Dagenham takes in a number of hotels. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.
Workshops and IT rooms at colleges like Barking and Dagenham College, 1.4 miles north of Dagenham, are re-serviced often, leaving penetrations to seal. Campus buildings at universities such as University of East London, 4.7 miles south-west of Dagenham, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Shop fits on retail sites such as Merrielands Retail Park (0.9 miles south-west of Dagenham) can bring new services through fire-resisting walls between units, to be sealed with the specified product.
Dagenham is about 3 miles south of Romford, in Greater London. Any commercial site in Dagenham is covered, for single jobs and planned programmes alike. Dagenham is one of 764 places we cover in Greater London for service penetrations. London is covered too, some 11 miles away.

Different surfaces, different methods
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.
