Fire Rated Sealant in St George's Hill
Intumescent and fire-rated sealant around gaps, frames and service penetrations for homes and businesses in St George's Hill and across Surrey. Fully insured, ARBOMaster approved and guaranteed for a year.
- Old fire sealant that has split or come away
- Door frames with gaps between frame and wall
- Gaps flagged on a fire risk assessment
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Do not paint over fire sealant until it has cured
- Include fire stopping when you schedule refits
- File the fire-stopping record where your assessor can find it
- Keep general-purpose foam and caulk away from fire-stopping gaps
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
About our fire rated sealant in St George's Hill
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We are often asked to deal with open joints along the top of partitions and gaps filled with a product that isn’t fire-rated, on pipe & cable gaps, plasterboard & masonry and service penetrations.
Commercial work around a smaller place like St George's Hill generally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Do you need fire rated sealant in St George's Hill?
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Common reasons people contact us are:
- Open gaps behind door architraves
- Fire seals that have cracked with movement
- Sealant items on a fire risk assessment action list
- Damaged fire sealant left by other trades
If you look after a church, hall or community building such as United Reform Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Leave it or put it right?
Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Around St George's Hill, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Fire rated sealant in St George's Hill: local notes
St George's Hill has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
If you let a flat or house near Weybridge station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Manby Lodge Infant School, fire-stopping around service openings should be restored whenever new services go in.

St George's Hill questions
Can you help a landlord with a rental near Weybridge station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you take on hotel work around St George's Hill?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is standard sealant good enough for a fire gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
Do you certify the fire stopping?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.
What does intumescent mean?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. A visit to St George's Hill is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Mention any tricky access
