Fire rated sealant for homes and businesses in North Hinksey
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on, one gap at a time. Typical jobs include gaps around pipes and cables through fire-resisting walls and unsealed gaps around fire door frames, across service penetrations, linear gaps and flats & HMOs.
Around a place like North Hinksey, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.
Big or small, you get the same one-year guarantee.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Tell trades working in the building that fire seals must be put back
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Include hidden areas like risers in routine checks
- Keep photos of seals that will be hidden
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
What happens if it’s left?
Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we’ll tell you. In an older home around North Hinksey, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit usually makes better use of the time than several visits. You’ll get one clear quote for the whole job.

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. A visit to North Hinksey is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- 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.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

North Hinksey questions
Will you come out to North Hinksey?
Yes, North Hinksey is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Oxford station. Can you help?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you tell me how many minutes the seal will last?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Where do you work from?
Mr Mastic is based in Crawley. We cover North Hinksey and the rest of Oxfordshire.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
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 fitted to the maker’s details.
Signs you need fire rated sealant in North Hinksey
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.
Keep an eye out for these signs:
- Open gaps behind door architraves
- Old fire sealant that has split or come away
- Standard silicone or caulk in a fire-stopping gap
- Open holes round services passing through fire walls
If you look after a church, hall or community building such as St Peter and St Paul, gaps around pipes and cables are worth checking after any building work there.

What the job involves on each surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length so there are no open sections left.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
