How we handle fire rated sealant in Broomhall
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’re often asked to deal with seals cut through by electricians, plumbers or data installers and standard silicone or caulk in a fire-stopping gap, across flats & HMOs, door frames and pipe & cable gaps.
If you run a pub, café, guest house or shop in or near Broomhall, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Big or small, you get the same 12-month guarantee in Broomhall and across Windsor and Maidenhead.

Workplaces and buildings in Broomhall
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 work to the specification you are given, installing the product to its tested details.
Community buildings like Holy Trinity Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. If you look after a building such as Sunningdale School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Landmarks near Broomhall
We work in homes and buildings around Charters School, Silwood Park and Holy Trinity CofE Primary School. There’s a railway station in Broomhall itself: Sunningdale station.

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 and needn’t wait for anything else. In an older home around Broomhall, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Landlords, agents and businesses in Broomhall

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Broomhall: your questions answered
I let a flat near Sunningdale station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Will you come out to Broomhall?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is standard sealant good enough for a fire gap?
No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Do you seal gaps around fire door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door leaf and its hardware need a door specialist.
Can you tell me how many minutes the seal will last?
That isn’t something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it, recording the locations and products.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Common problems we fix in Broomhall
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
The most common problems we see are:
- Holes left by a change of layout
- Joints picked up in a fire-stopping survey
- Open gaps behind door architraves
- Open joints along the top of partitions
For landlords with property near Sunningdale station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What affects the quote in Broomhall

- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What sealant work can’t fix
It helps to know what we cannot do too:
- Fire doors that need new seals, closers or hardware
- A wall that isn’t a fire-resisting element to begin with
- Big openings where sealant alone isn’t the tested solution
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a smaller place like Broomhall, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
