Fire rated sealant in Bitterne Park
We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Typical jobs include gaps where walls meet ceilings or slabs and old fire sealant that has split or come away, across service penetrations, flats & HMOs and pipe & cable gaps.
If you run a pub, café, guest house or shop in or near Bitterne Park, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Surface by surface
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance so residents know what to expect.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

What we’re called out for in Bitterne Park
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Most people get in touch when they notice one of these:
- Open holes round services passing through fire walls
- Unsealed gaps around fire door frames
- Holes left by a change of layout
- Joints picked up in a fire-stopping survey
For landlords with property near Bitterne station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Leave it or put it right?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. In an older home around Bitterne Park, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
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’ll explain the quote if you ask.

What fire rated sealant looks like in Bitterne Park
If you run a hotel, guest house or holiday let in a coastal place like Bitterne Park, 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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Managing a site like St Mary's Independent School? Then fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Church of Ascension, older buildings that have had new heating or wiring often have service gaps worth checking.

Quotes for fire rated sealant in Bitterne Park
For a quick quote, just ask. The main things that affect it are:
- The old material and how stubborn it is
- The type of sealant required
- How easy the joints are to reach
- Mould in or behind the old joints
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- Where the property is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Plan fire stopping into any work that goes through walls or floors
- Tell trades working in the building that fire seals must be put back
- Keep photos of seals that will be hidden
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
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. In a smaller place like Bitterne Park, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Getting ready for the visit
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

Advice
Bitterne Park: your questions answered
I let a flat near Bitterne station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Bitterne Park?
Yes, Bitterne Park is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How long does fire rated sealant take?
A typical job takes a few hours for a handful of gaps, and longer for a whole building, including the preparation. Your quote will say how long we expect yours to take.
What does intumescent mean?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
Do you certify the fire stopping?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it, recording the locations and products.
Do you seal gaps around fire door frames?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself and we will tell you if we spot problems with the door.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
What does fire rated sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
