What affects the cost of fire rated sealant

- Whether there’s mould to deal with
- How many areas need sealing
- Whether old sealant or filler has to be cut out

Fire rated sealant in Upper Farringdon
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, gap by gap. If you have seals cut through by electricians, plumbers or data installers and linear gaps at the head of walls, we can put it right, on service penetrations, linear gaps and pipe & cable gaps alike.
Somewhere as small as Upper Farringdon, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Every job is covered by a one-year guarantee, wherever you are in Hampshire.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Different surfaces, different methods
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Walls or floors that weren’t built to resist fire
- Certifying a building or signing off its fire safety
- Openings too large for sealant, which need batts, boards or another system
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Linear gaps
- Service penetrations
- Flats & HMOs
- Pipe & cable gaps
- Plasterboard & masonry
- Door frames
Fire rated sealant around Upper Farringdon
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.
Rented homes near Alton station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. Community buildings like Church of All Saints are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Upper Farringdon, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can

Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Take photos of fire stopping before ceilings or boxing go back
- Keep the record of products and locations with your fire safety documents
- Do not paint over fire sealant until it has cured
- Do not fill fire-stopping gaps with ordinary foam or silicone
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
