How we handle fire rated sealant in North Sheen
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on linear gaps, door frames and service penetrations, and people most often call us about gaps where walls meet ceilings or slabs and gaps filled with a product that isn’t fire-rated.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in North Sheen, and room-by-room programmes can be planned where needed.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why deal with it now?
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in North Sheen, the repair is bigger than a sealant job.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

What affects the cost of fire rated sealant
Jobs vary more than people expect. The main factors:
- Working hours on commercial sites
- How many areas need sealing
- The size of the job
- The type of sealant required
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What we need to know
Before you ask for a quote, have a think about:
- Roughly how big the job is
- Where the property is
- Whether it has been sealed before
- Access, such as stairs, a lift or height
Asking for a quote is easy: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Your questions about fire rated sealant in North Sheen
Is parking a problem for a job in North Sheen?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work in hotels near North Sheen?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can you fill the gap behind a fire door frame?
Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.
Can you tell me how many minutes the seal will last?
We do not give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it with a record of each location.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed.
Do you need fire rated sealant in North Sheen?
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.
Most people get in touch after spotting something like this:
- Ordinary sealant used where a fire-rated product was needed
- Joints picked up in a fire-stopping survey
- Gaps where walls meet ceilings or slabs
- Open gaps behind door architraves
If you look after a building such as Kew Riverside Primary School, service openings in fire-resisting walls need checking after any refurbishment.
What your quote should include
- The length of the guarantee
- Whether VAT is included
- Is the old sealant removed completely?
- How hidden problems are handled
When something else is needed
A few problems are outside what sealant work can do:
- Sign-off of the building, which sits with building control or your assessor
- Problems with the door itself rather than the gap around the frame
- Fire risk assessments, which need a qualified assessor
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Pipe & cable gaps
- Door frames
- Flats & HMOs
- Linear gaps
- Plasterboard & masonry
- Service penetrations
Looking after it afterwards
Looking after new joints is easy:
- Check risers, ceiling voids and cupboards during building checks
- Keep the record of products and locations with your fire safety documents
- Keep photos of seals that will be hidden
- Don’t paint over fire sealant until it has cured
Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. In North Sheen, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

Service penetrations
New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth.
