Upper Upnor Fire Rated Sealant
Fire-stopping gaps in Upper Upnor need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Gaps flagged on a fire risk assessment
- Holes left by a change of layout
- Seals cut through by electricians, plumbers or data installers
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- File the fire-stopping record where your assessor can find it
- Ask which product was used before you paint
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Flag any open gap you spot round a pipe or cable
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
About our fire rated sealant in Upper Upnor
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We are often asked to deal with unsealed gaps around fire door frames and standard silicone or caulk in a fire-stopping gap, on plasterboard & masonry, service penetrations and flats & HMOs.
Somewhere as small as Upper Upnor, 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.
Our work is backed for twelve months.

Upper Upnor: your questions answered
Do you work in hotels near Upper Upnor?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Will you come out to Upper Upnor?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Upper Upnor, along with the rest of our area.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you do fire sealant around door frames?
Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What the job involves on each surface
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run.
Why deal with it now?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. Around Upper Upnor, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Why us?
- Old sealant always removed completely
- Experience in homes, commercial sites and hotels
- Every job guaranteed for a year
- 20+ years of sealant experience

When to call us in Upper Upnor
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Look out for these signs:
- Open gaps behind door architraves
- Standard silicone or caulk in a fire-stopping gap
- Joints picked up in a fire-stopping survey
- Linear gaps at the head of walls
Community buildings like St Philip & St James are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
