How we handle fire rated sealant in Felbridge
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. We are often asked to deal with door frames with gaps between frame and wall and gaps flagged on a fire risk assessment, across service penetrations, linear gaps and plasterboard & masonry.
In a village or hamlet like Felbridge, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Common problems we fix in Felbridge
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
If you can see any of these, it’s time to have the joints looked at:
- Gaps left after a refit or conversion
- Open holes round services passing through fire walls
- Standard silicone or caulk in a fire-stopping gap
- Cracked or shrunken fire-rated sealant
If you look after a church, hall or community building such as St John's Felbridge, older buildings that have had new heating or wiring often have service gaps worth checking.

Why deal with it now?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job. Around Felbridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Felbridge: your questions answered
Is Felbridge in your area for fire rated sealant?
Yes, Felbridge is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Do you work for landlords with property near East Grinstead station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will we have a record of what was sealed?
Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.
What does fire rated sealant cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you certify the fire stopping?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.
What sealant work can’t fix
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Fire risk assessments, which need a qualified assessor
- Openings too large for sealant, which need batts, boards or another system
- Construction that does not provide fire resistance on its own
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.
Surfaces we seal

Fire rated sealant around Felbridge
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 building such as Felbridge Primary School, fire-stopping around service openings should be restored whenever new services go in. For landlords with property near East Grinstead station, any gap left by new services in shared walls should be closed with a fire-rated product.

What else we do in Felbridge
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
Different surfaces, different methods
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each.
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Felbridge needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We plan the order of work and access, floor by floor or flat by flat.
- 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.
- We record what was done and flag anything that needs a different system.
How to prepare
- Mention any tricky access
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive

How to look after the new joints
To keep the joints looking good and working properly:
- Keep photos of seals that will be hidden
- Ask which product was used before you paint
- Flag any open gap you spot round a pipe or cable
- Store the list of sealed gaps with your building paperwork
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.
