Fire rated sealant for homes and businesses in Hursley
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We work on linear gaps, door frames and pipe & cable gaps, and the jobs we see most are fire stopping disturbed by later work and unsealed gaps around fire door frames.
In a village or hamlet like Hursley, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
Big or small, you get the same one-year guarantee.

What the job involves on each surface
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Keep photos of seals that will be hidden
- Make resealing part of every contractor’s brief
- Keep the record of products and locations with your fire safety documents
- Check risers, ceiling voids and cupboards during building checks
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
What we can’t put right
A few problems are outside what sealant work can do:
- Issuing a fire rating or certificate for a building
- Deciding what fire stopping a building needs
- Doors that are not fire doors in the first place
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Plasterboard & masonry
- Service penetrations
- Door frames
- Linear gaps
- Pipe & cable gaps
- Flats & HMOs
What we do, step by step
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a small place like Hursley, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
- Mention any tricky access

Commercial buildings in Hursley
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
If you look after a building such as John Keble Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of All Saints, gaps around pipes and cables are worth checking after any building work there.

Do you need fire rated sealant in Hursley?
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
Most people get in touch after spotting something like this:
- Linear gaps at the head of walls
- Holes left by a change of layout
- Sealant items on a fire risk assessment action list
- Fire seals that have cracked with movement
Letting a property close to Shawford station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Hursley questions
Will you come out to Hursley?
Yes. Hursley is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

How do I get a quote for fire rated sealant in Hursley?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email and tell us what needs doing and where.
Where are you based?
Mr Mastic is based in Crawley. We cover Hursley and the rest of Hampshire, along with the rest of our area.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can I use normal mastic around a pipe through a fire wall?
No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service and we can apply it for you.
Can you tell me how many minutes the seal will last?
We don’t give ratings or certificates for our work. Your specification sets the requirement, and we fit a product whose tested details meet it, recording the locations and products.
Is there a guarantee?
Yes. All our work carries a one-year guarantee.
Why act early in Hursley
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Around Hursley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
