Surface by surface
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
Fire rated sealant for homes and businesses in Braishfield
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. We’re often asked to deal with open joints along the top of partitions and fire stopping disturbed by later work, on plasterboard & masonry, pipe & cable gaps and linear gaps.
For a small place like Braishfield, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Braishfield questions
I let a flat near Romsey station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Will you come out to Braishfield?
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.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll say how long yours will take.
Where is Mr Mastic based?
We work from Crawley. We cover Braishfield and the rest of Hampshire.
Do you work in flats, HMOs and commercial buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Out-of-hours work can be arranged.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Do you offer different sealant colours?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Braishfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your files.
Getting ready for the visit
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

Advice
Commercial buildings in Braishfield
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 work to the specification you are given, installing the product to its tested details.
If you look after a building such as Braishfield Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Church of All Saints, gaps around pipes and cables are worth checking after any building work there.

What’s near Braishfield
Typical jobs here are in homes near The Romsey School and The Wheatsheaf pub and the streets around them. The nearest railway station is Romsey station, roughly 2.4 miles south-west. Well-known places in the area include King Johns House (2.7 miles south-west) and Romsey Community Hospital (2.2 miles south). Not far away are Emer Bog and Baddesley Common.
What happens if it’s left?
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we’ll tell you. Around Braishfield, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Common problems we fix in Braishfield
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.
These are the problems we are asked about most:
- Old fire sealant that has split or come away
- Sealant items on a fire risk assessment action list
- Linear gaps at the head of walls
- Ordinary sealant used where a fire-rated product was needed
Letting a property close to Romsey station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
How we quote for fire rated sealant
Jobs vary more than people expect. What affects the quote:
- The product the joint needs
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
Combining jobs into one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Any previous sealing or DIY work
- The problem you’ve noticed
- Where the job is, and your postcode
- The rough size of the job
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or send us an email.
When it isn’t the sealant
To be straight with you, there are a few things sealant won’t fix:
- Issuing a fire rating or certificate for a building
- Doors that are not fire doors in the first place
- Large holes that need a different fire-stopping system
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
