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.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail.
Fire rated sealant in Underriver
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on linear gaps, flats & HMOs and service penetrations, and common reasons people get in touch are sealant items on a fire risk assessment action list and open holes round services passing through fire walls.
If you have holiday lets, a converted barn used for business or a community building near Underriver, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Each job carries a 12-month guarantee, whatever its size.

Your questions about fire rated sealant in Underriver
I let a flat near Hildenborough station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Is Underriver within the area you cover?
Yes, Underriver is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Can you fill the gap behind a fire door frame?
Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door, its seals and closer are for a door specialist.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What affects the quote in Underriver
Some jobs are bigger than they look, and some smaller. The main factors:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Any working-time requirements on site
- Access and height
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Whether it has been sealed before
- The type of property
- Any access issues, like height or stairs
- The rough size of the job
Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or email us and describe the job.
When to call us in Underriver
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Most people get in touch when they notice one of these:
- Damaged fire sealant left by other trades
- Holes left by a change of layout
- Gaps filled with a product that isn’t fire-rated
- Fire seals that have cracked with movement
For buildings such as Church of St Margaret, older buildings that have had new heating or wiring often have service gaps worth checking.
What your quote should include
- What preparation is included
- Whether they seal over old material or remove it
- Is VAT in the price?
- How the colour is chosen
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Ask which product was used before you paint
- Take pictures of fire stopping before ceilings or boxing go back
- Check risers, ceiling voids and cupboards during building checks
- Never patch a fire seal with standard sealant
Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A wall that is not a fire-resisting element to begin with
- Issuing a fire rating or certificate for a building
- Openings too large for sealant, which need batts, boards or another system
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- Door frames
- Pipe & cable gaps
- Linear gaps
- Plasterboard & masonry

Fire rated sealant around Underriver

Letting a property close to Hildenborough station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
