Fire rated sealant for homes and businesses in Upton
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That’s the part we focus on, one gap at a time. Typical jobs include fire seals that have cracked with movement and sealant items on a fire risk assessment action list, across service penetrations, flats & HMOs and linear gaps.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Upton.
Whatever the size of the job, you get the same 12-month guarantee in Upton and across Greater London.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Flag any open gap you spot round a pipe or cable
- Keep the record of products and locations with your fire safety documents
- Include hidden areas like risers in routine checks
- Include fire stopping when you schedule refits
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

The process
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work generally takes anything from a few hours to several days, depending on how many gaps there are. For a job in Upton, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.

Advice
Upton: your questions answered
Do you work in hotels near Upton?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Is parking a problem for a job in Upton?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What does intumescent mean?
An intumescent sealant expands when it gets hot. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Where do you work from?
Our base is Crawley. Our area covers South East England, London and Scotland.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Deciding what fire stopping a building needs
- Problems with the door itself rather than the gap around the frame
- Construction that does not provide fire resistance on its own
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.
What we seal
- Flats & HMOs
- Pipe & cable gaps
- Plasterboard & masonry
- Linear gaps
- Door frames
- Service penetrations
When to call us in Upton
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
Any of these means the joints need attention:
- New service routes left unsealed after building work
- Sealant items on a fire risk assessment action list
- Open holes round services passing through fire walls
- Fire stopping disturbed by later work
Managing a site like Upland Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.
Before booking anyone
- Are they insured?
- What product goes in the joint
- Whether all the old sealant comes out first
- How long to leave it before use

Different surfaces, different methods

Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.
