Fire rated sealant in Thorley Street, done properly
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. If you have gaps flagged on a fire risk assessment and old fire sealant that has split or come away, we can help.
For a small place like Thorley Street, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Commercial buildings in Thorley Street
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 work to the specification you’re given, installing the product to its tested details.
If you look after a church, hall or community building such as Parish Church of St James the Great, gaps around pipes and cables are worth checking after any building work there. Letting a property close to Bishops Stortford station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What happens if it’s left?
A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Where a wall is exposed, as many are in small places like Thorley Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
When it is not the sealant
Before you book, it’s worth knowing the limits too:
- Construction that doesn’t provide fire resistance on its own
- Openings too large for sealant, which need batts, boards or another system
- Certifying a building or signing off its fire safety
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- Flats & HMOs
- Service penetrations
- Pipe & cable gaps
- Linear gaps
- Plasterboard & masonry
- Door frames
What the job involves on each surface
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.

Questions from Thorley Street
Is Thorley Street within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Bishops Stortford station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
What fire rating will the seal have?
We don’t give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it with a record of each location.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Will we have a record of what was sealed?
Yes. You get a list of where we worked and what we used to keep with your fire safety documents.
Can you work in occupied buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.

Advice
Signs you need fire rated sealant in Thorley Street
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.
Keep an eye out for these signs:
- Fire seals that have cracked with movement
- Sealant items on a fire risk assessment action list
- Fire stopping disturbed by later work
- Standard silicone or caulk in a fire-stopping gap
For site and facilities teams at buildings such as Thorley Hill Primary School, service openings in fire-resisting walls need checking after any refurbishment.
What your quote should include
- What happens if the job turns out different
- Are they insured?
- How the surfaces are prepared before sealing
- The length of the guarantee
How to look after the new joints
Aftercare is simple:
- Flag any open gap you spot round a pipe or cable
- Make resealing part of every contractor’s brief
- File the fire-stopping record where your assessor can find it
- Never patch a fire seal with standard sealant
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot and we’ll tell you which one you have.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record.
