Fire-rated sealant in Kingston, Kent
Our applicators work in Kingston on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

Fire rated sealant for homes and businesses in Kingston
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We’re often asked to deal with open holes round services passing through fire walls and gaps filled with a product that isn’t fire-rated, on service penetrations, plasterboard & masonry and door frames.
Work in a small place like Kingston is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Landlords and agents in Kingston can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Why act early in Kingston
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that doesn’t depend on other work. Older cottages and farmhouses around Kingston 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 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 will explain the quote if you ask.

Do you need fire rated sealant 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.
Common reasons people contact us include:
- Door frames with gaps between frame and wall
- Unsealed gaps where pipes and cables go through a wall
- Cracked or shrunken fire-rated sealant
- Gaps filled with a product that isn’t fire-rated
Community buildings like Church of St Giles are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
Questions to ask before booking
- Who turns up on the day
- The length of the guarantee
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
What the job involves on each surface
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach and we will flag it.
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length leaving no stretch unsealed.
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Kingston, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- 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
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on

Advice
What sealant work cannot fix
Before booking, it’s worth knowing the limits:
- Issuing a fire rating or certificate for a building
- Fire risk assessments, which need a qualified assessor
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Where we work in Kingston
- Service penetrations
- Plasterboard & masonry
- Pipe & cable gaps
- Flats & HMOs
- Linear gaps
- Door frames
How to look after the new joints
After the cure time, these simple habits help:
- Tell trades working in the building that fire seals must be put back
- Check risers, ceiling voids and cupboards during building checks
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Take pictures of fire stopping before ceilings or boxing go back
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded.

We work to the specification you are given, installing the product to its tested details.
Rented homes near Adisham station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
