Fire rated sealant in Knowl Hill, done properly
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on, gap by gap. If you have seals cut through by electricians, plumbers or data installers and unsealed gaps around fire door frames, we can put it right, on plasterboard & masonry, door frames and flats & HMOs alike.
Somewhere as small as Knowl Hill, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
You get a 12-month guarantee, the same in Knowl Hill as everywhere else we work.

Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Deciding what fire stopping a building needs
- Large holes that need a different fire-stopping system
- A wall that isn’t a fire-resisting element to begin with
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Other services in Knowl Hill
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Landlords, agents and businesses in Knowl Hill
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Why deal with it now?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job that doesn’t depend on other work. Around Knowl Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and send you a clear quote before we start.
Why us?
- 20+ years of sealant experience
- Sanitary silicone with an anti-fungal additive in wet areas
- 12-month guarantee on every job
- We leave the area clean and tidy

How we quote for fire rated sealant
We quote each job individually. These are the things that affect it:
- How many rooms, windows or areas are involved
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- How we’d reach the joints
- Whether it has been sealed before
- Whether it’s a home or a business
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, ring 0345 464 0079 or email us.
The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on how many gaps there are for a typical job. Somewhere like Knowl Hill needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Before starting, we go through the specification or action list with you.
- 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 and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Tell us about any water getting in
How to get a quote
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we will come back to you with a quote.
Advice
What the job involves on each surface
Door frames
Frame gaps are generally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run so there are no open sections left.

I let a flat near Wargrave station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will you assess my building’s fire safety?
No, we do not assess buildings. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.
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. The old sealant has to come out completely.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Will we have a record of what was sealed?
Yes. We record the locations we’ve sealed and the products used to keep with your fire safety documents.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Commercial buildings in Knowl Hill
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 let a flat or house near Wargrave station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Saint Peter, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Knowl Hill Church of England Primary Academy, fire-stopping around service openings should be restored whenever new services go in.
