How the job changes by surface
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist and we’ll mention anything we notice.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.
Fire rated sealant in Wytham
Bigger jobs can be worked through in stages, flat by flat or floor by floor. It gives you a list to keep with the building’s fire safety documents. If you’re dealing with fire stopping disturbed by later work and cracked or shrunken fire-rated sealant, we can put it right, whatever the surface.
Somewhere as small as Wytham, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Our work is backed for twelve months, in Wytham and everywhere else we cover.

When to call us in Wytham
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
These are the problems we are asked about most:
- Damaged fire sealant left by other trades
- New service routes left unsealed after building work
- Cracked or shrunken fire-rated sealant
- Ordinary sealant used where a fire-rated product was needed
Letting a property close to Oxford Parkway station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
What to look for in a quote
- What the cure time is
- What insurance they hold
- Which colour the sealant will be
- Whether they seal over old material or remove it
Leave it or put it right?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a small place like Wytham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

DIY versus a professional finish
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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. For a village or hamlet like Wytham, 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.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed

Schools such as Oxford Academy are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Church of All Saints, service openings in its walls need the right fire-rated sealant, as in any building.

Common questions in Wytham
Is Wytham within the area you cover?
Yes, Wytham is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Wytham for fire rated sealant?
Yes, Wytham is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Do you seal gaps around fire door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product, to the product’s details. The door leaf and its hardware need a door specialist.
How long will you be here?
Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
Do you certify the fire stopping?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
Where do you work from?
Mr Mastic is based in Crawley. We cover Wytham and the rest of Oxfordshire.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
