Fire-rated sealant in Little Mill, Kent
Problem with your fire-stopping gaps in Little Mill? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.

- Gaps around pipes and cables through fire-resisting walls
Fire rated sealant in Little Mill, done properly
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’re dealing with gaps flagged on a fire risk assessment and seals cut through by electricians, plumbers or data installers, we can help, on flats & HMOs, pipe & cable gaps and door frames alike.
If you have holiday lets, a converted barn used for business or a community building near Little Mill, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Signs you need fire rated sealant in Little Mill
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.
People usually contact us when they notice one of these:
- Fire seals that have cracked with movement
- Holes left by a change of layout
- Gaps filled with a product that isn’t fire-rated
- Unsealed gaps around fire door frames
For buildings such as Church of the Holy Trinity, older buildings that have had new heating or wiring often have service gaps worth checking.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
The process
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Little Mill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Aftercare tips
To keep the joints looking good and working properly:
- Flag any open gap you spot round a pipe or cable
- Keep photos of seals that will be hidden
- File the fire-stopping record where your assessor can find it
- Allow for resealing whenever new services are run
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
What affects the cost of fire rated sealant
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
