Why it’s worth doing now in Redbridge
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 will say so if a gap needs something other than sealant. Older cottages and farmhouses around Redbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Fire rated sealant for homes and businesses in Redbridge
We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. We work on door frames, service penetrations and flats & HMOs, and the jobs we see most are standard silicone or caulk in a fire-stopping gap and old fire sealant that has split or come away.
For a small place like Redbridge, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Workplaces and buildings in Redbridge
If you run a hotel, guest house or holiday let in a coastal place like Redbridge, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
If you let a flat or house near Redbridge station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

The process

The visit itself usually takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job.

- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- 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.
Getting ready for the visit

Advice
Redbridge questions
Do you work for hotels and guest houses in Redbridge?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Do you cover smaller places like Redbridge?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
How do I get a quote for fire rated sealant in Redbridge?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:
- Openings too large for sealant, which need batts, boards or another system
- Fire doors that need new seals, closers or hardware
- Certifying a building or signing off its fire safety
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
What we seal
- Linear gaps
- Plasterboard & masonry
- Pipe & cable gaps
- Service penetrations
- Door frames
- Flats & HMOs
How the job changes by surface
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment, flat by flat if needed.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
When to call us in Redbridge
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
It’s worth asking for a quote if you see:
- Unsealed gaps around fire door frames
- Fire seals that have cracked with movement
- New service routes left unsealed after building work
- Sealant items on a fire risk assessment action list
If you look after a building such as Redbridge Primary School, service openings in fire-resisting walls need checking after any refurbishment.
