Minsted Fire Rated Sealant
Fire-stopping gaps in Minsted need attention? We remove the old material, prepare the joints and seal them properly.
- Old fire sealant that has split or come away
- Seals cut through by electricians, plumbers or data installers
- Gaps where walls meet ceilings or slabs
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. Older cottages and farmhouses around Minsted can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What affects the cost of fire rated sealant
There’s no set price list, because no two jobs are the same. What we look at:
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- Any mould that needs treating
- Which sealant suits the joint
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- Where the property is
We quote each job on its own. Simply phone 0345 464 0079 or send us an email and describe the job and send photos if you have them.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Minsted: your questions answered
Do you cover Minsted for fire rated sealant?
Yes. Our work covers London and the South East, and Minsted is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Is fire rated sealant in Minsted guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
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. The order of work and access are planned with you.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
What we do, step by step
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. In a small place like Minsted, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
How to prepare
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
- Tell us if parking is tricky

What fire rated sealant looks like in Minsted
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.
Managing a site like Stedham Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as The Parish Church of St James, gaps around pipes and cables are worth checking after any building work there.

Different surfaces, different methods
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Look in service cupboards and ceiling voids from time to time
- Do not paint over fire sealant until it has cured
- Allow for resealing whenever new services are run
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
