Fire-rated sealant in Upton, Southampton
Fire rated sealant across Upton and nearby, with old sealant always removed completely and a 12-month guarantee.
- Seals cut through by electricians, plumbers or data installers
- Standard silicone or caulk in a fire-stopping gap
- Fire seals that have cracked with movement
Fire rated sealant in Upton
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. If you have open gaps behind door architraves and damaged fire sealant left by other trades, we can put it right.
In a village or hamlet like Upton, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

How the job changes by surface
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for the gap we are sealing.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Why it’s worth doing now in Upton
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Older cottages and farmhouses around Upton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Allow for resealing whenever new services are run
- Make resealing part of every contractor’s brief
- Flag any open gap you spot round a pipe or cable
- Don’t paint over fire sealant until it has cured
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot, so ask us which we used.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded so the item can be closed.

Upton: your questions answered
I let a flat near Redbridge station. Can you help?
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 price.
Do you cover smaller places like Upton?
Yes. Upton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How do I get a quote for fire rated sealant in Upton?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
Can you tell me how many minutes the seal will last?
We do not certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and list the locations and products for you.
Fire rated sealant in Upton: local notes
If you run a hotel, guest house or holiday let in a coastal place like Upton, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 Nursling Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Church of St John, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Redbridge station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
