- Gaps filled with a product that isn’t fire-rated

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Fire rated sealant in Leigh-on-Sea
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. If you have ordinary sealant used where a fire-rated product was needed and linear gaps at the head of walls, we can help, whatever the surface.
Commercial work around a smaller place like Leigh-on-Sea usually means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Common questions in Leigh-on-Sea
Can you do fire rated sealant in Leigh-on-Sea?
Yes, Leigh-on-Sea is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Leigh-on-Sea station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you provide details of the products used?
Yes. Every gap we seal is listed with the product used, so you have it on file.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Do you take on fire stopping in schools and offices?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Quotes for fire rated sealant in Leigh-on-Sea
Every job gets its own quote. These are the things that affect it:

What we need to know
To help us quote quickly, please include:
- Any previous sealing or DIY work
- Photos by email, if that is easy
- The address or postcode of the job
- How many joints, rooms or windows are involved
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.
Signs you need fire rated sealant in Leigh-on-Sea
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
Keep an eye out for any of the following:
- Joints picked up in a fire-stopping survey
- Door frames with gaps between frame and wall
- Open holes round services passing through fire walls
- Seals cut through by electricians, plumbers or data installers
Schools such as West Leigh Infant School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
Questions to ask before you book
- Whether all the old sealant comes out first
- What happens if the job turns out different
- How the surfaces are prepared before sealing
- What the cure time is
Why deal with it now?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. Around Leigh-on-Sea, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we’ll talk you through it.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Problems with the door itself rather than the gap around the frame
- Fire risk assessments, which need a qualified assessor
- Construction that does not provide fire resistance on its own
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
Where we work in Leigh-on-Sea
- Flats & HMOs
- Pipe & cable gaps
- Linear gaps
- Service penetrations
- Plasterboard & masonry
- Door frames
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Report cracked or damaged seals as soon as you notice them
- Store the list of sealed gaps with your building paperwork
- Check risers, ceiling voids and cupboards during building checks
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is usually a straightforward job.
Commercial buildings in Leigh-on-Sea
For seaside hotels, guest houses and holiday lets around Leigh-on-Sea, 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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For landlords with property near Leigh-on-Sea station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Church of St Margaret of Antioch, older buildings that have had new heating or wiring often have service gaps worth checking.
