How we handle fire rated sealant in Forest Green
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. If you are dealing with cracked or shrunken fire-rated sealant and unsealed gaps where pipes and cables go through a wall, we can put it right.
In a village or hamlet like Forest Green, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Common questions in Forest Green
Do you cover Forest Green for fire rated sealant?
Yes. We work across London and the South East, and Forest Green is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Ockley station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Can you tell me how many minutes the seal will last?
That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
How long will you be here?
A typical job takes from a few hours to a few days, depending on the number of gaps and the access, including the preparation. Your quote will say how long we expect yours to take.
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.
How the visit works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Forest Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints
- Tell us about any water getting in

What else we do in Forest Green
What fire rated sealant looks like in Forest Green
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For landlords with property near Ockley station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Do you need fire rated sealant in Forest Green?
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.
The problems people usually mention when they call include:
- Open holes round services passing through fire walls
- Holes left by a change of layout
- Gaps where walls meet ceilings or slabs
- Fire stopping disturbed by later work
For buildings such as Holy Trinity, service openings in its walls need the right fire-rated sealant, as in any building.
Questions to ask before you book
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
- The length of the guarantee
- What happens if they find a problem under the old sealant
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

- The number of rooms or windows
- The size of the job
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

When something else is needed
It helps to know what we can’t do:

Aftercare tips
Aftercare is simple:
- Never patch a fire seal with standard sealant
- File the fire-stopping record where your assessor can find it
- Do not paint over fire sealant until it has cured
- Check risers, ceiling voids and cupboards during building checks
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
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.
