Fire-rated sealant in Inner Avenue, Southampton
We cover Inner Avenue for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.
- Gaps filled with a product that is not fire-rated
- Linear gaps at the head of walls
- Fire seals that have cracked with movement
Do you need fire rated sealant in Inner Avenue?
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
These are the problems we are asked about most:
- Fire stopping disturbed by later work
- Gaps left after a refit or conversion
- Open joints along the top of partitions
- Cracked or shrunken fire-rated sealant
Schools such as Bevois Town Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
Questions to ask before you book
- What product goes in the joint
- What guarantee comes with the work
- Which colour the sealant will be
- Who turns up on the day
Fire rated sealant in Inner Avenue
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That’s the part we focus on, one gap at a time. If you have old fire sealant that has split or come away and fire stopping disturbed by later work, we can put it right.
Commercial work around a smaller place like Inner Avenue normally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Fire rated sealant in Inner Avenue: local notes
If you run a hotel, guest house or holiday let in a coastal place like Inner Avenue, 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 work to the specification you’re given, installing the product to its tested details.
For landlords with property near St Denys station, any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Saint Mary's, older buildings that have had new heating or wiring often have service gaps worth checking.

Landmarks near Inner Avenue
Typical jobs here are in homes near St Anne's Catholic School, St Mary's Independent School and Rockstone Place Park and the streets around them.

Why deal with it now?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. Around Inner Avenue, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear quote before we start.

What affects the cost of fire rated sealant
We don’t publish a price list, because jobs vary so much. What we look at:
- Any working-time requirements on site
- The amount of work
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Whether it’s a home or a business
- Where the job is, and your postcode
- Roughly how big the job is
- How we’d reach the joints
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.
What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- Large holes that need a different fire-stopping system
- Problems with the door itself rather than the gap around the frame
- Issuing a fire rating or certificate for a building
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Joints and surfaces we work on

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. A visit to Inner Avenue is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- 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.
Preparing for the visit
- Tell us about any water getting in
- Tell us if parking is tricky
- Clear the area around the work

How the job changes by surface
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist, and we’ll say if we spot a problem with them.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each and we flag any that need another system.
Inner Avenue: your questions answered
Is Inner Avenue within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near St Denys station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before work begins.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Can you fill the gap behind a fire door frame?
Yes, if the gap is within the product’s tested range. Our work is the gap around the frame.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
