The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Trotton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed

How we handle fire rated sealant in Trotton
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. Typical jobs include holes left by a change of layout and gaps flagged on a fire risk assessment, on linear gaps, flats & HMOs and plasterboard & masonry.
If you have holiday lets, a converted barn used for business or a community building near Trotton, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach 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’s fine. We cut it out and start again.
What we can’t put right
A few problems are outside what sealant work can do:
- Fire risk assessments, which need a qualified assessor
- Large holes that need a different fire-stopping system
- Fire doors that need new seals, closers or hardware
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Linear gaps
- Door frames
- Service penetrations
- Pipe & cable gaps
- Plasterboard & masonry
- Flats & HMOs
Why deal with it now?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. Older cottages and farmhouses around Trotton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Trotton: your questions answered
Is there a guarantee on fire rated sealant in Trotton?
All our work, in Trotton and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Will you come out to Trotton?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Where are you based?
Mr Mastic is based in Crawley. We cover Trotton and the rest of Hampshire.
Do you have insurance?
Yes. We are fully insured.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Do you work in flats, HMOs and commercial buildings?
Yes. Occupied flats, HMOs, offices and schools are all fine, with access planned around residents or staff. Early starts or out-of-hours work can be arranged if that suits the building.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What affects the quote in Trotton
Every job gets its own quote. This is what makes a difference:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- Whether there’s mould to deal with
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.
Asking for a quote
When you contact us, it’s useful to know:
- The problem you’ve noticed
- Photos by email, if that’s easy
- How we’d reach the joints
- Where the property is
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work before giving you a price.
What the job involves on each surface
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Don’t paint over fire sealant until it has cured
- Photograph sealed gaps before they’re covered up
- Include hidden areas like risers in routine checks
- Keep the record of products and locations with your fire safety documents
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
Workplaces and buildings in Trotton
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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
For site and facilities teams at buildings such as Stedham Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St George's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
