About our fire rated sealant in Eynsford
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. We work on service penetrations, door frames and pipe & cable gaps, and people most often call us about open gaps behind door architraves and fire stopping disturbed by later work.
For a small place like Eynsford, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
There’s a 12-month guarantee on every job, whatever its size.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Why it’s worth doing now in Eynsford
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Where a wall is exposed, as many are in small places like Eynsford, wind-driven rain gets into any failed joint, 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. Call for a quick quote and we’ll explain what it covers.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Eynsford, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises

Related advice
Fire rated sealant in Eynsford: local notes
Eynsford has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like Church of Saint Martin are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as The Anthony Roper Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Include hidden areas like risers in routine checks
- Keep the record of products and locations with your fire safety documents
- Tell trades working in the building that fire seals must be put back
- Get damaged fire seals looked at promptly
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

What the job involves on each surface

Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Eynsford: your questions answered
Can you help a landlord with a rental near Eynsford station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do you work for hotels and guest houses in Eynsford?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Where do you work from?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Is standard sealant good enough for a fire gap?
No. It looks sealed but won’t perform as fire stopping. A tested fire-rated product is needed, or ask us to do it.
Will we have a record of what was sealed?
Yes. Locations and products are written up when we finish. If you need photos or a set layout, ask when you get a quote.
Do you certify the fire stopping?
Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
When it is not the sealant
Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Walls or floors that weren’t built to resist fire
- Fire doors that need new seals, closers or hardware
- Issuing a fire rating or certificate for a building
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.
