Common questions in Southsea
Do you cover Southsea for fire rated sealant?
Yes. We work across London and the South East, and Southsea is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Can you help a landlord with a rental near Fratton station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you certify the fire stopping?
We do not give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it.
Where do you work from?
We work from Crawley. We cover Southsea and the rest of Portsmouth.
Do you take on fire stopping in schools and offices?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
Can you tell me which gaps need fire stopping?
No. That’s for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before we start.
About our fire rated sealant in Southsea
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. If you are dealing with unsealed gaps around fire door frames and damaged fire sealant left by other trades, we can put it right, whatever the surface.
In a town like Southsea, commercial work can mean offices, shops, schools, surgeries or small business units. Each has washrooms, kitchens and service openings through walls that need the right sealant.
You get a one-year guarantee, the same in Southsea as everywhere else we work.

How the job changes by surface
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Never patch a fire seal with standard sealant
- Check risers, ceiling voids and cupboards during building checks
- Store the list of sealed gaps with your building paperwork
- Check whether a sealant can be painted before decorating over it
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Quotes for fire rated sealant in Southsea
There’s no set price list, because jobs vary so much. What we look at:
- Working hours on commercial sites
- Whether the work is at height
- Which sealant suits the joint
- The old material and how stubborn it is
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- The type of property
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or drop us an email.
Commercial buildings in Southsea
For seaside hotels, guest houses and holiday lets around Southsea, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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’re given, installing the product to its tested details.
Community buildings like St Margaret of Scotland are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Craneswater Junior School, service openings in fire-resisting walls need checking after any refurbishment.

What we do, step by step
Good joint work is mostly 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. For a job in Southsea, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Getting ready for the visit
- Let us know about stairs, lifts or work at height

Common problems we fix in Southsea
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Look out for these signs:
- Ordinary sealant used where a fire-rated product was needed
- Holes left by a change of layout
- Seals cut through by electricians, plumbers or data installers
- Joints picked up in a fire-stopping survey
Letting a property close to Fratton station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Why it’s worth doing now in Southsea
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. Around Southsea, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
