When to call us in Foster Street
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
Keep an eye out for any of the following:
- Door frames with gaps between frame and wall
- Gaps left after a refit or conversion
- Damaged fire sealant left by other trades
- Fire seals that have cracked with movement
Schools such as Henry Moore Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

About our fire rated sealant in Foster Street
Deciding which gaps need fire stopping is not our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on door frames, plasterboard & masonry and pipe & cable gaps, and common reasons people get in touch are open holes round services passing through fire walls and gaps flagged on a fire risk assessment.
Work in a small place like Foster Street is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
You get a 12-month guarantee, the same in Foster Street as everywhere else we work.

The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Foster Street needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Looking after it afterwards
So the new joints stay in good condition:
- Take photos of fire stopping before ceilings or boxing go back
- Ask which product was used before you paint
- Plan fire stopping into any work that goes through walls or floors
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.
Foster Street: your questions answered
Do you cover smaller places like Foster Street?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Foster Street in your area for fire rated sealant?
Yes, Foster Street is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
Will you assess my building’s fire safety?
No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Why act early in Foster Street
Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again when the building is next checked. Around Foster Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Why us?
- Anti-fungal silicone where joints get wet
- Arbo and Everbuild products

Other services in Foster Street
Workplaces and buildings in Foster Street
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 are given, installing the product to its tested details. Foster Street is part of Harlow, one of the post-war new towns. Harlow was planned with its own industrial and business areas, so workplaces sit close to the homes. Each has washrooms, kitchens and fire-rated joints to keep in order.
Letting a property close to Harlow Mill station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking.

Surface by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it.
Honest limits
A few problems are outside what sealant work can do:
- Assessing a building’s fire safety
- Issuing a fire rating or certificate for a building
- Fire doors that need new seals, closers or hardware
