Fire rated sealant for homes and businesses in Hindhead
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. If you have gaps left after a refit or conversion and open joints along the top of partitions, we can help, whatever the surface.
In a village or hamlet like Hindhead, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- How many areas need sealing
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
There’s no need for technical detail. Just tell us:
- If someone has resealed it before
- A few photos by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will talk you through the work and give you a clear quote.
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Hindhead needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
Before we arrive
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on

Common questions in Hindhead
Can you help a landlord with a rental near Haslemere station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Will you come out to Hindhead?

Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can ordinary silicone be used in a fire-stopping gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Can you fill the gap behind a fire door frame?
Yes. The joint between frame and wall is sealed with a fire-rated sealant, to the product’s details. The door leaf and its hardware need a door specialist.

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Commercial buildings in Hindhead
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 St Luke, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as St Edmund's School, service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Haslemere station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Surface by surface
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size.
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Photograph sealed gaps before they’re covered up
- Include hidden areas like risers in routine checks
- Allow for resealing whenever new services are run
- Make resealing part of every contractor’s brief
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own. In a small place like Hindhead, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
