Fire rated sealant in Shirley
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on plasterboard & masonry, door frames and flats & HMOs, and common reasons people get in touch are holes left by a change of layout and joints picked up in a fire-stopping survey.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Where a building in Shirley needs to stay open, work can be planned outside normal hours.
Our work is backed for twelve months.

Why act early in Shirley
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

What else we do in Shirley
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Ask every contractor to reseal any fire stopping they disturb
- Report cracked or damaged seals as soon as you notice them
- Include fire stopping when you schedule refits
- Do not paint over fire sealant until it has cured
Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
Fire rated sealant in Shirley: local notes
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
Managing a site like Oasis Academy Shirley Park? Then gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as St George The Martyr Church, service openings in its walls need the right fire-rated sealant, as in any building. Shirley is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

When it isn’t the sealant
We’ll always be straight with you, so here’s what new sealant will not do:
- Big openings where sealant alone isn’t the tested solution
- Sign-off of the building, which sits with building control or your assessor
- Fire risk assessments, which need a qualified assessor

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours for a handful of gaps, and longer for a whole building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Keep children and pets away from the work area
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks

Shirley questions
Is Shirley in your area for fire rated sealant?
Yes, Shirley is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Elmers End station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you seal gaps around fire door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door, its seals and closer are for a door specialist.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Shirley, along with the rest of our area.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
