Fire-rated sealant in Kingston, Portsmouth
We cover Kingston for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Unsealed gaps where pipes and cables go through a wall
- Standard silicone or caulk in a fire-stopping gap
- Fire stopping disturbed by later work
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Fire rated sealant in Kingston
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you have fire seals that have cracked with movement and gaps where walls meet ceilings or slabs, we can put it right, whatever the surface.
In a smaller place like Kingston, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
You’re covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

How the job changes by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
Flats and HMOs
Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and record where they are.
Why deal with it now?
Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Around Kingston, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

What we do, step by step
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. In a smaller place like Kingston, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.

Advice
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Photograph sealed gaps before they’re covered up
- Never patch a fire seal with standard sealant
- Flag any open gap you spot round a pipe or cable
- Ask every contractor to reseal any fire stopping they disturb
Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
Workplaces and buildings in Kingston
For seaside hotels, guest houses and holiday lets around Kingston, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Kingston has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
If you let a flat or house near Fratton station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Church of St Cuthbert are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

When to call us in Kingston
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
Any of these means the joints need attention:
- Holes left by a change of layout
- Gaps flagged on a fire risk assessment
- Fire seals that have cracked with movement
- Standard silicone or caulk in a fire-stopping gap
For site and facilities teams at buildings such as Miltoncross Academy, gaps opened by contractors for new cabling are a common finding in schools and offices.
