About our fire rated sealant in Windsor
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We work on flats & HMOs, pipe & cable gaps and door frames, and people most often call us about open joints along the top of partitions and fire seals that have cracked with movement.
Commercial jobs in a town like Windsor range from shops and offices to schools and small business units. Each has washrooms, kitchens and service openings through walls that need the right sealant.
Your job is guaranteed for a year, as with all our work.

What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- A wall that isn’t a fire-resisting element to begin with
- Assessing a building’s fire safety
- Doors that aren’t fire doors in the first place
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal

Aftercare tips
After the cure time, these simple habits help:
- Ask every contractor to reseal any fire stopping they disturb
- Check risers, ceiling voids and cupboards during building checks
- Take photos of fire stopping before ceilings or boxing go back
- Get damaged fire seals looked at promptly
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.
What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. A visit in Windsor needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
How to prepare
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

How we quote for fire rated sealant
We quote each job individually. This is what makes a difference:
- The size of the job
- How easy the joints are to reach
- Mould in or behind the old joints
- Which sealant suits the joint
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- If someone has resealed it before
- What’s wrong with the joints now
- Photos by email, if that is easy

What else we do in Windsor
Windsor questions
Do you work for hotels and guest houses in Windsor?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you do fire rated sealant in Windsor?
Yes. Our work covers London and the South East, and Windsor is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
What fire rating will the seal have?
We do not certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and giving you a record of where it went.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before we start.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one option among several. We use whichever the specification and tested details call for.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How long does the job take?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we’re called out for in Windsor
In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.
Keep an eye out for any of the following:
- Linear gaps at the head of walls
- Cracked or shrunken fire-rated sealant
- Unsealed gaps around fire door frames
- Holes left by a change of layout
If you look after a building such as St Edward's Catholic First School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Fire rated sealant in Windsor: local notes
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. There are hotels and other places to stay in and around Windsor. Hotel work can be planned room by room, with out-of-hours working where needed.
If you look after a church, hall or community building such as All Saints Church, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Windsor & Eton Central station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

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 does not depend on other work. In a family home in Windsor, a failed seal around a bath or a frame lets water into places you cannot see, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
