Rableyheath Fire Rated Sealant
Intumescent and fire-rated sealant around gaps, frames and service penetrations for homes and businesses in Rableyheath and across Hertfordshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Unsealed gaps where pipes and cables go through a wall
- New service routes left unsealed after building work
- Ordinary sealant used where a fire-rated product was needed
Fire rated sealant in Rableyheath, done properly
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. We work on door frames, pipe & cable gaps and plasterboard & masonry, and people most often call us about standard silicone or caulk in a fire-stopping gap and gaps where walls meet ceilings or slabs.
If you have holiday lets, a converted barn used for business or a community building near Rableyheath, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
There’s a 12-month guarantee on every job.

FAQs for Rableyheath
Is Rableyheath within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Knebworth station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. We use whichever the specification and tested details call for.
How we quote for fire rated sealant
Call for a quick quote. The main things that affect it are:
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Whether the work is at height
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- Where the job is, and your postcode
- A few pictures by email, if you can
- The type of property
Every job is quoted individually. Just call 0345 464 0079 or drop us an email with the details.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we are called out for in Rableyheath
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
Common reasons people contact us include:
- Standard silicone or caulk in a fire-stopping gap
- Cracked or shrunken fire-rated sealant
- Gaps where walls meet ceilings or slabs
- Gaps around pipes and cables through fire-resisting walls
Community buildings like Church of St Michael and All Angels are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Photograph sealed gaps before they’re covered up
- Store the list of sealed gaps with your building paperwork
- Look in service cupboards and ceiling voids from time to time
- Tell trades working in the building that fire seals must be put back
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
What the job involves on each surface
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified, flat by flat if needed.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Rableyheath, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on

Schools such as St Michael's Woolmer Green CofE VA Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
