Fire rated sealant in Oakhanger, done properly
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. We work on door frames, pipe & cable gaps and flats & HMOs, and common reasons people get in touch are open holes round services passing through fire walls and gaps flagged on a fire risk assessment.
Somewhere as small as Oakhanger, 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.
There’s a 12-month guarantee on every job.

What happens on the day
We work through the job in order: 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 we leave things clean and tidy. For a village or hamlet like Oakhanger, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.

DIY sealant or a professional job?
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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Common problems we fix in Oakhanger
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried.
These are the problems we are asked about most:
- Open holes round services passing through fire walls
- Old fire sealant that has split or come away
- Gaps left after a refit or conversion
- Gaps where walls meet ceilings or slabs
Managing a site like Mill Chase Academy? Then fire-stopping around service openings should be restored whenever new services go in.
What your quote should include
- What product goes in the joint
- Whether VAT is included
- Who turns up on the day
- What the cure time is
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Include hidden areas like risers in routine checks
- Keep the record of products and locations with your fire safety documents
- Take photos of fire stopping before ceilings or boxing go back
- Get damaged fire seals looked at promptly
Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
What happens if it’s left?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. Older cottages and farmhouses around Oakhanger can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Will you leave a mess?

Workplaces and buildings in Oakhanger
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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
Letting a property close to Alton station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as St Mary Magdalene's Church, older buildings that have had new heating or wiring often have service gaps worth checking.
