Fire-rated sealant in Mackney, Oxfordshire

- Holes left by a change of layout
- Unsealed gaps around fire door frames
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Fire rated sealant in Mackney
Deciding which gaps need fire stopping isn’t our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Common call-outs are for open holes round services passing through fire walls and seals cut through by electricians, plumbers or data installers, across flats & HMOs, service penetrations and door frames.
Somewhere as small as Mackney, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
All of our work is guaranteed for twelve months.

Do you need fire rated sealant in Mackney?
In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
These are the problems we’re asked about most:
- Fire stopping disturbed by later work
- Old fire sealant that has split or come away
- Open holes round services passing through fire walls
- New service routes left unsealed after building work
If you look after a church, hall or community building such as Church of St Agatha, older buildings that have had new heating or wiring often have service gaps worth checking.

Mackney questions
Will you come out to Mackney?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Cholsey station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can ordinary silicone be used in a fire-stopping gap?
No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.
Do you take on fire stopping in schools and offices?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we will plan around it.
How do I get a quote for fire rated sealant in Mackney?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Where do you work from?
We’re based in Crawley, and we cover South East England, London and all of Scotland.

Why it’s worth doing now in Mackney
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 sealing itself is often a contained piece of work. Around Mackney, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Flag any open gap you spot round a pipe or cable
- Plan fire stopping into any work that goes through walls or floors
- Photograph sealed gaps before they’re covered up
- Ask every contractor to reseal any fire stopping they disturb
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t, so ask us which we used.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.
