Fire rated sealant in Aperfield
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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. If you’re dealing with gaps left after a refit or conversion and open gaps behind door architraves, we can put it right.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Aperfield, and room-by-room programmes can be planned where needed.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Make resealing part of every contractor’s brief
- Keep the record of products and locations with your fire safety documents
- Allow for resealing whenever new services are run
- Keep pictures of seals that will be hidden
Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.
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.

What else we do in Aperfield
Commercial buildings in Aperfield
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. 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.
As a London address, Aperfield can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Rented homes near Oxted station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

Quotes for fire rated sealant in Aperfield
We quote each job individually. This is what makes a difference:
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- The number and length of the joints
- Any mould that needs treating
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
There’s no need for technical detail. Just tell us:
- If someone has resealed it before
- The type of property
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
We do not publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To get started, phone 0345 464 0079 or send us an email.
Landlord and commercial work in Aperfield
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a London area like Aperfield, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- 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
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
Related advice
What happens if it’s left?
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we will tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Aperfield, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear quote before work begins.

Aperfield: your questions answered
Can parking be tricky for a visit in Aperfield?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is Aperfield in your area for fire rated sealant?
Yes, Aperfield is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
When to call us in Aperfield
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.
It’s worth asking for a quote if you see:
- Standard silicone or caulk in a fire-stopping gap
- Sealant items on a fire risk assessment action list
- Open holes round services passing through fire walls
- New service routes left unsealed after building work
Community buildings like St Mark's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
