How the job changes by surface
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
Fire rated sealant in Lower Cadsden, done properly
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. We work on linear gaps, service penetrations and door frames, and people most often call us about new service routes left unsealed after building work and ordinary sealant used where a fire-rated product was needed.
For holiday lets, converted business premises or a community building near Lower Cadsden, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Each job carries a 12-month guarantee, whatever its size.

Do you cover smaller places like Lower Cadsden?
Yes. Lower Cadsden is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Monks Risborough station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we will sort it.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Can you tell me how many minutes the seal will last?
We don’t give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.
Do you seal gaps around fire door frames?
Yes, if the gap is within the product’s tested range. Our work is the gap around the frame, and we’ll mention anything we notice about the door.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but won’t perform as fire stopping. A tested fire-rated product is needed.

Advice
Common problems we fix in Lower Cadsden
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, especially where it was squeezed in at the end of a project.
If you can see any of these, it’s time to have the joints looked at:
- Standard silicone or caulk in a fire-stopping gap
- Fire seals that have cracked with movement
- Gaps where walls meet ceilings or slabs
- Unsealed gaps where pipes and cables go through a wall
Schools such as Monks Risborough CofE Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Why deal with it now?
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 and needn’t wait for anything else. In a small place like Lower Cadsden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
