How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of gaps, and longer for a whole building, and the area is left clean. In a small place like Compton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
How to prepare
- Tell us if parking is tricky
- Tell us about any water getting in
- Move anything stored near the joints

Fire rated sealant in Compton
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 service penetrations, door frames and flats & HMOs, and people most often call us about unsealed gaps around fire door frames and seals cut through by electricians, plumbers or data installers.
In a village or hamlet like Compton, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

What happens if it’s left?
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that doesn’t depend on other work. In a small place like Compton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Fire rated sealant around Compton
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’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Compton All Saints Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Church of All Saints, service openings in its walls need the right fire-rated sealant, as in any building.

Common questions in Compton
Is Compton within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Shawford station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Will you assess my building’s fire safety?
No. We work from the specification you give us.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.
Landlords, agents and businesses in Compton
Landlords and agents in Compton can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Aftercare tips
Looking after new joints is easy:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Flag any open gap you spot round a pipe or cable
- Keep the record of products and locations with your fire safety documents
- Plan fire stopping into any work that goes through walls or floors
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Do you need fire rated sealant in Compton?
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Keep an eye out for these signs:
- Standard silicone or caulk in a fire-stopping gap
- Damaged fire sealant left by other trades
- Holes left by a change of layout
- Gaps where walls meet ceilings or slabs
For landlords with property near Shawford station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
What your quote should include
- Whether they’re fully insured
- Whether all the old sealant comes out first
- How long the guarantee is
- How much experience the applicator has
Different surfaces, different methods
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.
