Fire Rated Sealant in Mountfield
Our applicators work in Mountfield on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Gaps where walls meet ceilings or slabs
- Gaps around pipes and cables through fire-resisting walls
- Unsealed gaps around fire door frames
How we handle fire rated sealant in Mountfield
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. If you have new service routes left unsealed after building work and door frames with gaps between frame and wall, we can put it right, on linear gaps, door frames and service penetrations alike.
If you have holiday lets, a converted barn used for business or a community building near Mountfield, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
All of our work is guaranteed for twelve months.

What fire rated sealant looks like in Mountfield
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
If you look after a church, hall or community building such as The Parish Church of All Saints, gaps around pipes and cables are worth checking after any building work there. Managing a site like Vinehall School? Then service openings in fire-resisting walls need checking after any refurbishment.

Looking after it afterwards
Looking after new joints is easy:
- Photograph sealed gaps before they’re covered up
- Check risers, ceiling voids and cupboards during building checks
- Check whether a sealant can be painted before decorating over it
- Allow for resealing whenever new services are run
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we will tell you which one you have.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
FAQs for Mountfield
Can you do fire rated sealant in Mountfield?
Yes. We work across London and the South East, and Mountfield is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Is Mountfield within the area you cover?
Yes. Mountfield is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
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.
What fire rating will the seal have?
Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and giving you a record of where it went.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.

What else we do in Mountfield
What we’re called out for in Mountfield
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 after spotting something like this:
- Door frames with gaps between frame and wall
- Standard silicone or caulk in a fire-stopping gap
- Old fire sealant that has split or come away
- Fire stopping disturbed by later work
For landlords with property near Robertsbridge station, any gap left by new services in shared walls should be closed with a fire-rated product.
What to look for in a quote
- The length of the guarantee
- How the joint is cleaned and prepared
- How the colour is chosen
- What insurance they hold
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Landlord and commercial work in Mountfield
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Why act early in Mountfield
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In a small place like Mountfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Big openings where sealant alone isn’t the tested solution
- Issuing a fire rating or certificate for a building
- Deciding what fire stopping a building needs
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Flats & HMOs
- Plasterboard & masonry
- Service penetrations
- Door frames
- Linear gaps
- Pipe & cable gaps
The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. In a small place like Mountfield, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
Before we arrive
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
