Fire stopping in West Ham, done properly
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, call 01277 525 020 or email drawings and photos with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on linear gaps at wall heads, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are fire sealant pulled out of the opening and service penetrations left open after M&E works. Whether you call it commercial sealant work, mastic application or joint sealing, the work in West Ham is the same: the right product in a properly prepared joint.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Penetration seals near West Ham
In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. Plenty of hotels sit less than 2 miles from West Ham. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
At a university such as University of East London (0.8 miles north-west of West Ham), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a unit at a centre such as Stratford Centre, 0.7 miles to the north-west of West Ham, penetration seals are worth checking after each shop fit. At a healthcare site like Newham University Hospital, 1.4 miles to the south-east of West Ham, new services through compartment walls are a constant, and each needs the specified seal.
West Ham is about 2 miles west of East Ham, in Greater London. Across the E15 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Greater London, 764 places are covered, including West Ham.
Work on service penetrations is covered throughout E15, E13 and E7, whatever the building. We cover commercial and managed buildings on Plaistow Grove, Willis Road and Moorey Close and the roads nearby.

Further afield, our area takes in London (5 miles south-west), City of Westminster (7 miles west), Marylebone (7 miles west), Kensington (9 miles west), St Pancras (6 miles west) and Shoreditch (4 miles west).

When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Openings that need collars, wraps, batts or boards rather than sealant
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Signing off or certifying a building’s fire stopping
If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.

Why deal with it now?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. Failed sealant in a building in West Ham can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

- CHAS accredited
- Joints cleaned back to sound surfaces

Common questions from West Ham clients
Can you take on a job at a hospital such as Newham University Hospital?
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 on fire-rated sealing in hotels in West Ham?
Yes, to the specification and the product’s tested detail. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months on every job.
What will the job cost?
There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
After the work
A few simple habits keep the new joints working:
- Settle who seals which penetrations at the start of a project
- Treat an open penetration as a priority repair
- Check risers and ceiling voids after each round of works
- Put resealing into every M&E and fit-out package
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Different surfaces, different methods
Small ducts
Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we will never swap a specified collar for sealant.
What else we do in West Ham
Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in West Ham can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Tell us which areas need to stay in use
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work
