Norcott Hill Fire Rated Sealant
Intumescent and fire-rated sealant around gaps, frames and service penetrations for homes and businesses in Norcott Hill and across Hertfordshire. Fully insured, ARBOMaster approved and guaranteed for a year.

When to call us in Norcott Hill
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
People generally contact us when they notice something like this:
- Cracked or shrunken fire-rated sealant
- New service routes left unsealed after building work
- Door frames with gaps between frame and wall
- Damaged fire sealant left by other trades
For landlords with property near Tring station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Fire rated sealant for homes and businesses in Norcott Hill
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. Typical jobs include unsealed gaps around fire door frames and holes left by a change of layout, on service penetrations, linear gaps and pipe & cable gaps.
Work in a small place like Norcott Hill is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Your job is guaranteed for a year, as with all our work.

What fire rated sealant looks like in Norcott Hill
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.
For buildings such as Church of Saint Mary, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as St Mary's CofE Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How to look after the new joints
After the cure time, these simple habits help:
- Keep the record of products and locations with your fire safety documents
- Include hidden areas like risers in routine checks
- Flag any open gap you spot round a pipe or cable
- Check whether a sealant can be painted before decorating over it
Don’t 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.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

What else we do in Norcott Hill
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. Somewhere as small as Norcott Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Mention any tricky access

Advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Norcott Hill: your questions answered
Will you come out to Norcott Hill?
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.
Is Norcott Hill in your area for fire rated sealant?
Yes. We work across London and the South East, and Norcott Hill is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you do fire sealant around door frames?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame, and we’ll mention anything we notice about the door.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do you certify the fire stopping?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it, recording the locations and products.
Why act early in Norcott Hill
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Where a wall is exposed, as many are in small places like Norcott Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What you get with us
- We leave the area clean and tidy
- Every job guaranteed for a year
- Quality sealants from Arbo and Everbuild
- Sanitary silicone with an anti-fungal additive in wet areas
