About our fire stopping in Hammersmith
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on pipe penetrations, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are service penetrations left open after M&E works and head-of-wall gaps with no fire seal. A specialist sealant contractor works differently from a general builder: in Hammersmith, that means joint design, primers and backing rod as standard.
In a London area such as Hammersmith, 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.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Cost factors for service penetrations
We price every job individually. The things that drive the figure:
- Removal of failed or old sealant
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- Whether the work must be split into stages
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- Clear photographs of the problem areas
- Drawings or a marked-up plan, if available
- Access details, including height
- Whether an asbestos survey exists
To get a fixed quote, speak to us on 01277 525 020 or email us. You can also send details through our quote form.

What else we do in Hammersmith
Why deal with it now?
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
What you get with us
- One phone line for London, the South East and Scotland
- Public liability insurance in place
- A Constructionline member, so easy to vet
- Joints cleaned back to sound surfaces
See what affects the cost and our accreditations and insurance.
What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Reviewing a building’s overall fire safety
- Gaps in walls that were never built as compartment walls
- Large openings beyond what any sealant detail covers
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.
Where we work in Hammersmith
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Hammersmith can sit alongside others in a wider programme across Greater London.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
Hammersmith: questions and answers
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry.
Will you take on work at estates like Berghem Mews Business Village, close to Hammersmith?
Yes. We cover Hammersmith and the area around it, including industrial estates, business parks and retail parks such as Berghem Mews Business Village. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Do the same rules apply to fire stopping in Scotland?
Building standards in Scotland are separate from England’s, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. In Hammersmith, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Agree which areas must stay open
- Arrange parking or a loading space
- Share your working hours and any access restrictions
Ask for a quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Agree the fire-stopping specification before services go in
- Include service cupboards in routine inspections
- Check with the data sheet before painting over fire sealant
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.
Compartments and services around Hammersmith
There are a good number of hotels within about 2 miles of Hammersmith. 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. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
At a university such as Polish University Abroad (under half a mile south-east of Hammersmith), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Office fit-outs on sites such as Berghem Mews Business Village, 0.5 miles north-east of Hammersmith, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. For a site team at a college like St Mellitus Theological College, 1.8 miles to the east of Hammersmith, fire-rated sealing is best scheduled after the summer works.
