Fire-rated sealant in Gravesend, Hertfordshire
Problem with your fire-stopping gaps in Gravesend? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Linear gaps at the head of walls
- Gaps left after a refit or conversion
- Sealant items on a fire risk assessment action list
What we are called out for in Gravesend
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.
If you can see any of these, it’s time to have the joints looked at:
- Cracked or shrunken fire-rated sealant
- New service routes left unsealed after building work
- Linear gaps at the head of walls
- Open holes round services passing through fire walls
For buildings such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking.

About our fire rated sealant in Gravesend
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That detail is what we take care over, one gap at a time. We work on flats & HMOs, door frames and linear gaps, and common reasons people get in touch are unsealed gaps where pipes and cables go through a wall and gaps left after a refit or conversion.
In a village or hamlet like Gravesend, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What else we do in Gravesend
What fire rated sealant looks like in Gravesend
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 work to the specification you’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Albury Church of England Voluntary Aided Primary School, fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Bishops Stortford station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Your questions about fire rated sealant in Gravesend
I let a flat near Bishops Stortford station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover smaller places like Gravesend?
Yes. Gravesend is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
How much does fire rated sealant cost in Gravesend?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Do you provide details of the products used?
Yes. When the job is done, we give you the locations and products. If you need pictures or a set layout, ask when you get a quote.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Do you guarantee your work?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
Honest limits
A few problems are outside what sealant work can do:
- Construction that doesn’t provide fire resistance on its own
- Doors that are not fire doors in the first place
- Deciding what fire stopping a building needs
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Gravesend 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 plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- 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
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children

Different surfaces, different methods
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment, flat by flat if needed.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required.
