About our fire rated sealant in Calbourne
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment. If you share the list, we can quote for the gaps that need fire-rated sealant. If you’re dealing with holes left by a change of layout and standard silicone or caulk in a fire-stopping gap, we can help, on flats & HMOs, door frames and service penetrations alike.
Somewhere as small as Calbourne, 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.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Quotes for fire rated sealant in Calbourne
There’s no set price list, because no two jobs are the same. The quote depends on:
- The size of the job
- Whether there’s mould to deal with
- How easy the joints are to reach
- Which sealant suits the joint
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
To make quoting easier, let us know:
- Any previous sealing or DIY work
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- The problem you’ve noticed
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
Aftercare tips
A little care helps the new joints last. Our advice:
- File the fire-stopping record where your assessor can find it
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Include fire stopping when you schedule refits
- Don’t paint over fire sealant until it has cured
Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
Why it’s worth doing now in Calbourne
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. In a small place like Calbourne, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why choose Mr Mastic in Calbourne

Signs you need fire rated sealant in Calbourne
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Any of these means the joints need attention:
- Gaps left after a refit or conversion
- Gaps around pipes and cables through fire-resisting walls
- Door frames with gaps between frame and wall
- Cracked or shrunken fire-rated sealant
If you look after a church, hall or community building such as All Saints' Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Workplaces and buildings in Calbourne
For seaside hotels, guest houses and holiday lets around Calbourne, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
In and around Calbourne, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
Questions from Calbourne
Is fire rated sealant in Calbourne guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Will you come out to Calbourne?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Do you take on fire stopping in schools and offices?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Calbourne.
Is standard sealant good enough for a fire gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
