About our fire rated sealant in Preston Crowmarsh
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. If you have cracked or shrunken fire-rated sealant and sealant items on a fire risk assessment action list, we can put it right.
For a small place like Preston Crowmarsh, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
You get a 12-month guarantee, the same in Preston Crowmarsh as everywhere else we work.

Workplaces and buildings in Preston Crowmarsh
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 work to the specification you’re given, installing the product to its tested details. There are hotels and other places to stay in and around Preston Crowmarsh. Hotel work can be planned room by room, with out-of-hours working where needed.
For buildings such as Church of St Helen, service openings in its walls need the right fire-rated sealant, as in any building. For landlords with property near Cholsey station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Different surfaces, different methods
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each and we flag any that need another system.
When it isn’t the sealant
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
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
Where we work in Preston Crowmarsh
- Linear gaps
- Pipe & cable gaps
- Door frames
- Service penetrations
- Flats & HMOs
- Plasterboard & masonry
What happens if it’s left?
Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In a small place like Preston Crowmarsh, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

FAQs for Preston Crowmarsh
Will you come out to Preston Crowmarsh?
Yes. Preston Crowmarsh is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Cholsey station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Preston Crowmarsh, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
How to get a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
Advice
When to call us in Preston Crowmarsh
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Any of these means the joints need attention:
- Damaged fire sealant left by other trades
- Unsealed gaps around fire door frames
- Ordinary sealant used where a fire-rated product was needed
- Joints picked up in a fire-stopping survey
Managing a site like Benson Church of England Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.
