Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Fire rated sealant for homes and businesses in Little London
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. If you have gaps around pipes and cables through fire-resisting walls and gaps filled with a product that isn’t fire-rated, we can put it right.
For a small place like Little London, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
All our work comes with our 12-month guarantee, wherever you are in Hampshire.

Landlord and commercial work in Little London
Landlords and letting agents in Little London can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Different surfaces, different methods
Door frames
Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length so there are no open sections left.
Why it’s worth doing now in Little London
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. We’ll say so if a gap needs something other than sealant. Around Little London, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Common problems we fix in Little London
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
People generally contact us after spotting one of these:
- New service routes left unsealed after building work
- Ordinary sealant used where a fire-rated product was needed
- Fire seals that have cracked with movement
- Open holes round services passing through fire walls
Letting a property close to Bramley (Hants) station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Your questions about fire rated sealant in Little London
Can you help a landlord with a rental near Bramley (Hants) station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Little London?
Yes, Little London is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What fire rating will the seal have?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it, recording the locations and products.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
How long will you be here?
That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We’ll give you a better idea when we quote.
Is intumescent sealant the same as fire-rated sealant?
An intumescent sealant expands when it gets hot. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
What fire rated sealant looks like in Little London
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like Saint Stephen's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
