Common questions in Fernhurst
Is Fernhurst within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do fire rated sealant in Fernhurst?
Yes. We work across London and the South East, and Fernhurst is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Do you do fire sealant around door frames?
Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
How long will you be here?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We’ll give you a better idea when we quote.
Where are you based?
We work from Crawley. Our applicators cover Fernhurst, along with the rest of our area.
Can I use normal mastic around a pipe through a fire wall?
No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed and we can apply it for you.
Fire rated sealant for homes and businesses in Fernhurst
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. We work on linear gaps, service penetrations and pipe & cable gaps, and common reasons people get in touch are gaps filled with a product that isn’t fire-rated and gaps flagged on a fire risk assessment.
For a small place like Fernhurst, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

The process
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. In a small place like Fernhurst, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any tricky access
- Tell us about any water getting in

What else we do in Fernhurst
What fire rated sealant looks like in Fernhurst
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a church, hall or community building such as The Parish Church of St Margaret, gaps around pipes and cables are worth checking after any building work there.

What we cannot put right
In fairness, some problems need a different trade:
- Problems with the door itself rather than the gap around the frame
- Issuing a fire rating or certificate for a building
- Fire risk assessments, which need a qualified assessor
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- Pipe & cable gaps
- Service penetrations
- Linear gaps
- Door frames

Aftercare tips
After the cure time, these simple habits help:
- Include hidden areas like risers in routine checks
- Store the list of sealed gaps with your building paperwork
- Allow for resealing whenever new services are run
- Ask every contractor to reseal any fire stopping they disturb
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
What the job involves on each surface
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.
DIY sealant or a professional job?
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.
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.
Why act early in Fernhurst
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. In a small place like Fernhurst, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Signs you need fire rated sealant in Fernhurst
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
If you can see any of these, it’s time to have the joints looked at:
- Gaps filled with a product that is not fire-rated
- Door frames with gaps between frame and wall
- Open holes round services passing through fire walls
- Open joints along the top of partitions
If you look after a building such as Fernhurst Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
