About our fire rated sealant in North Warnborough
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We work on pipe & cable gaps, linear gaps and plasterboard & masonry, and common reasons people get in touch are standard silicone or caulk in a fire-stopping gap and gaps left after a refit or conversion.
For a small place like North Warnborough, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
Big or small, it’s backed by our 12-month guarantee.

FAQs for North Warnborough

Yes. Our work covers London and the South East, and North Warnborough is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
I let a flat near Hook station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Where are you based?
Mr Mastic is based in Crawley. We cover North Warnborough and the rest of Hampshire, along with the rest of our area.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How long will you be here?
It depends on the size of the job, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We will give you a better idea when we quote.
Do you take on fire stopping in schools and offices?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
What does intumescent mean?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

Why act early in North Warnborough
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. In a small place like North Warnborough, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email and we’ll talk you through it.

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 matched to the joint and its conditions, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
How the visit works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for a handful of gaps, and longer for a whole building. In a small place like North Warnborough, access is generally the main thing to plan. 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.
- 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.
Preparing for the visit
- Clear the area around the work
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Plan fire stopping into any work that goes through walls or floors
- Check whether a sealant can be painted before decorating over it
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Get damaged fire seals looked at promptly
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record.

How the job changes by surface
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist.
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment, flat by flat if needed.
What fire rated sealant looks like in North Warnborough
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
For landlords with property near Hook station, any gap left by new services in shared walls should be closed with a fire-rated product. Schools such as Robert May's School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

When to call us in North Warnborough
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.
Common reasons people contact us are:
- Gaps where walls meet ceilings or slabs
- Gaps flagged on a fire risk assessment
- Ordinary sealant used where a fire-rated product was needed
- Gaps around pipes and cables through fire-resisting walls
Community buildings like All Saints Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
