Fire rated sealant in Great Hollands, done properly
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. If you are dealing with holes left by a change of layout and cracked or shrunken fire-rated sealant, we can put it right, on service penetrations, linear gaps and flats & HMOs alike.
Around a place like Great Hollands, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

Why act early in Great Hollands
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In an older home around Great Hollands, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

What we are called out for in Great Hollands
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
The most common problems we see are:
- Cracked or shrunken fire-rated sealant
- Holes left by a change of layout
- Damaged fire sealant left by other trades
- Open holes round services passing through fire walls
Letting a property close to Bracknell station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

The process
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are for a typical job. A visit to Great Hollands is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your files.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each.
FAQs for Great Hollands
Do you cover smaller places like Great Hollands?
Yes, Great Hollands is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

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 remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Do you certify the fire stopping?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer.
What affects the cost of fire rated sealant
The quote reflects the job in front of us. We look at:
- The product the joint needs
- When we can work, for business premises
- Access and height
- Whether there’s mould to deal with
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it has been sealed before
- Pictures of the joints, sent by email
- Roughly how big the job is
- Whether it’s a home or a business
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Problems with the door itself rather than the gap around the frame
- Big openings where sealant alone isn’t the tested solution
- Walls or floors that weren’t built to resist fire
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Fire rated sealant in Great Hollands: local notes
Great Hollands is part of Bracknell, one of the post-war new towns. Bracknell was planned with its own industrial and business areas, so workplaces sit close to the homes. Each has washrooms, kitchens and fire-rated joints to keep in order. There are hotels and other places to stay in and around Great Hollands. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
If you look after a church, hall or community building such as St Michael and St Mary Magdalene's Church, service openings in its walls need the right fire-rated sealant, as in any building.

Looking after it afterwards
To keep the joints looking good and working properly:
- Include hidden areas like risers in routine checks
- File the fire-stopping record where your assessor can find it
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Plan fire stopping into any work that goes through walls or floors
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
