Fire rated sealant for homes and businesses in Ewell
We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. Common call-outs are for seals cut through by electricians, plumbers or data installers and new service routes left unsealed after building work, on plasterboard & masonry, service penetrations and pipe & cable gaps.
Commercial jobs in a town like Ewell range from shops and offices to schools and small business units. All of them have washroom and kitchen joints, and many have fire-rated joints around pipes and cables.
Each job carries a 12-month guarantee, large or small.

Do you hold any approvals?

No. We work neatly, protect the area around the joints and tidy up afterwards.
Do you have insurance?

Can you do several jobs on one visit?

Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Commercial buildings in Ewell
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 are given, installing the product to its tested details.
If you look after a building such as St Clement's Catholic Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Ewell West station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What else we do in Ewell
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on how many gaps there are. For a job in Ewell, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

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 against the product’s tested range.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach.
What affects the quote in Ewell
Call for a quick quote. What matters most is:
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- How many rooms, windows or areas are involved
- The product the joint needs
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
When you contact us, it’s useful to know:
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- Where the property is
- The type of property
We quote each job on its own. Just ring 0345 464 0079 or email us with the details, and pictures are welcome.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Plan fire stopping into any work that goes through walls or floors
- Keep the record of products and locations with your fire safety documents
- Don’t paint over fire sealant until it has cured
- Do not fill fire-stopping gaps with ordinary foam or silicone
Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.
Do you need fire rated sealant in Ewell?
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.
Look out for any of the following:
- Seals cut through by electricians, plumbers or data installers
- Unsealed gaps where pipes and cables go through a wall
- Ordinary sealant used where a fire-rated product was needed
- New service routes left unsealed after building work
Community buildings like St Mary's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Why it’s worth doing now in Ewell
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Black mould and gaps in sealant do not fix themselves, and in a busy home in Ewell they get worse with every use. Replacing the sealant now is the simplest fix.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
