- Gaps flagged on a fire risk assessment
- Open gaps behind door architraves
- Linear gaps at the head of walls
Surface by surface
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point to make sure it suits the product.
Flats and HMOs
Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product.
How we handle fire rated sealant in Newbury
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you have gaps where walls meet ceilings or slabs and open gaps behind door architraves, we can help, on pipe & cable gaps, flats & HMOs and plasterboard & masonry alike.
For holiday lets, converted business premises or a community building near Newbury, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

When it isn’t the sealant
We won’t take on work that will not last, so these are the limits:
- Construction that does not provide fire resistance on its own
- Openings too large for sealant, which need batts, boards or another system
- Certifying a building or signing off its fire safety
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Flats & HMOs
- Plasterboard & masonry
- Service penetrations
- Linear gaps
- Pipe & cable gaps
- Door frames
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Tell trades working in the building that fire seals must be put back
- Keep the record of products and locations with your fire safety documents
- Look in service cupboards and ceiling voids from time to time
- Never patch a fire seal with standard sealant
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
Leave it or put it right?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. In a small place like Newbury, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

How we quote for fire rated sealant
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether the work is at height
- Any working-time requirements on site
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- A few photos by email, if you can
- The type of property
- How we’d reach the joints
- How many joints, rooms or windows are involved
If you are in Newbury and need fire rated sealant, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean. Somewhere like Newbury needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

Fire rated sealant around Newbury
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
Rented homes near Teynham station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of St Catherine are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Common questions in Newbury
Do you cover Newbury for fire rated sealant?
Yes, Newbury is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Teynham station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How much does fire rated sealant cost in Newbury?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Can you tell me which gaps need fire stopping?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Common problems we fix in Newbury
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common.
Signs it’s time to call us include:
- Ordinary sealant used where a fire-rated product was needed
- Sealant items on a fire risk assessment action list
- Cracked or shrunken fire-rated sealant
- Door frames with gaps between frame and wall
For site and facilities teams at buildings such as Rodmersham School, fire-stopping around service openings should be restored whenever new services go in.
