Fire rated sealant in Alscot
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. We are often asked to deal with joints picked up in a fire-stopping survey and fire seals that have cracked with movement, across linear gaps, flats & HMOs and service penetrations.
For holiday lets, converted business premises or a community building near Alscot, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Big or small, it’s backed by our 12-month guarantee in Alscot and across Buckinghamshire.

How we quote for fire rated sealant
The price is agreed before any work begins. It takes into account:
- Any mould that needs treating
- Which sealant suits the joint
- The number of rooms or windows
- When we can work, for business premises
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What the problem is, such as mould, gaps, leaks or cracking
- A few photos by email, if you can
- Roughly how big the job is
- How we’d reach the joints
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, call 0345 464 0079 or email us.
Landlord and commercial work in Alscot
If you manage several properties in or around Alscot, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. Somewhere like Alscot needs a little journey planning: 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 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.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Getting ready for the visit
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
How to get a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Advice
What the job involves on each surface
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Doors that aren’t fire doors in the first place
- Large holes that need a different fire-stopping system
- Certifying a building or signing off its fire safety
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Service penetrations
- Pipe & cable gaps
- Plasterboard & masonry
- Door frames
- Linear gaps
- Flats & HMOs
Why it’s worth doing now in Alscot
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Older cottages and farmhouses around Alscot can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

How long does fire rated sealant take?
Typically it takes anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer.
Do you do fire sealant around door frames?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself.

No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Fire rated sealant in Alscot: local notes
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.
For buildings such as St Teresa's Church, gaps around pipes and cables are worth checking after any building work there. For landlords with property near Monks Risborough station, any gap left by new services in shared walls should be closed with a fire-rated product. Managing a site like Princes Risborough Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.
