Fire rated sealant for homes and businesses in Carshalton
We can work through a building room by room or floor by floor. It gives you a list to keep with the building’s fire safety documents. If you have cracked or shrunken fire-rated sealant and open holes round services passing through fire walls, we can help, whatever the surface.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Carshalton.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Carshalton: your questions answered
Do you cover Carshalton for fire rated sealant?
Yes. We work across London and the South East, and Carshalton is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
I let a flat near Carshalton station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before work begins.
Can you give us a record of the work?
Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.
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.
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are for a typical job. In Carshalton, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

Advice
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Never patch a fire seal with standard sealant
- Flag any open gap you spot round a pipe or cable
- Take pictures of fire stopping before ceilings or boxing go back
- Allow for resealing whenever new services are run
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record.

Workplaces and buildings in Carshalton
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Carshalton High School for Girls, fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Carshalton station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Do you need fire rated sealant in Carshalton?
Sometimes the wrong product was used from the start: 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.
Common reasons people contact us include:
- Standard silicone or caulk in a fire-stopping gap
- Damaged fire sealant left by other trades
- Joints picked up in a fire-stopping survey
- Linear gaps at the head of walls
Community buildings like Church of All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
What your quote should include
- Whether VAT is included
- Who does the work, and how experienced they are
- Which colour the sealant will be
- What preparation is included
What we cannot put right
A few problems are outside what sealant work can do:
- Sign-off of the building, which sits with building control or your assessor
- Large holes that need a different fire-stopping system
- Deciding what fire stopping a building needs
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
Where we work in Carshalton
- Pipe & cable gaps
- Linear gaps
- Flats & HMOs
- Plasterboard & masonry
- Service penetrations
- Door frames
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Why act early in Carshalton
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we will tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Carshalton, the repair is bigger than a sealant job.
