Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. In Grays, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before work begins.

Fire rated sealant for homes and businesses in Grays
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We work on plasterboard & masonry, service penetrations and pipe & cable gaps, and common reasons people get in touch are unsealed gaps around fire door frames and unsealed gaps where pipes and cables go through a wall.
For anyone managing a school, care home, pub or office in Grays, the sealant in its washrooms and kitchens, and the fire-rated joints around its pipework, all need looking after. Work can be planned around opening hours where needed.
There’s a 12-month guarantee on every job, large or small.
Signs you need fire rated sealant in Grays
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
If you can see any of these, it’s time to have the joints looked at:
- Joints picked up in a fire-stopping survey
- Door frames with gaps between frame and wall
- Unsealed gaps where pipes and cables go through a wall
- Damaged fire sealant left by other trades
Community buildings like St John the Evangelist are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Ask which product was used before you paint
- Check risers, ceiling voids and cupboards during building checks
- Never patch a fire seal with standard sealant
- Take pictures of fire stopping before ceilings or boxing go back
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product 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 fire rated sealant looks like in Grays
For seaside hotels, guest houses and holiday lets around Grays, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a building such as Quarry Hill Academy, fire-stopping around service openings should be restored whenever new services go in. For landlords with property near Grays station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of gaps, and longer for a whole building, including the tidy-up. Parking in a town like Grays is generally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- 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.
Preparing for the visit
- Clear items away from the joints we are working on
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
How much does fire rated sealant cost in Grays?

Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What fire rating will the seal have?
We do not give ratings or certificates for our work. Your specification sets the requirement, and we fit a product whose tested details meet it with a record of each location.
How we quote for fire rated sealant
Jobs vary more than people expect. What affects the quote:
- Working hours on commercial sites
- Mould in or behind the old joints
- The number of rooms or windows
- How much there is to do
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.
Helping us quote
To make quoting easier, let us know:
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
