About our fire rated sealant in Charlbury
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 are dealing with fire seals that have cracked with movement and fire stopping disturbed by later work, we can put it right, on linear gaps, plasterboard & masonry and pipe & cable gaps alike.
If you run a pub, café, guest house or shop in or near Charlbury, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Every job is covered by our one-year guarantee, wherever you are in Oxfordshire.

Signs you need fire rated sealant in Charlbury
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
These are the problems we are asked about most:
- Old fire sealant that has split or come away
- Gaps left after a refit or conversion
- Ordinary sealant used where a fire-rated product was needed
- Open holes round services passing through fire walls
Schools such as Charlbury Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:
- Fire risk assessments, which need a qualified assessor
- Issuing a fire rating or certificate for a building
- Construction that doesn’t provide fire resistance on its own
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Commercial buildings in Charlbury
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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Letting a property close to Charlbury station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like St Mary's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Charlbury questions
Do you cover smaller places like Charlbury?
Yes, Charlbury is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Charlbury for fire rated sealant?
Yes, Charlbury is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you have insurance?
Yes. We are fully insured.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Charlbury.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you work in occupied buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we will plan around it.
How the visit works
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a smaller place like Charlbury, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- On commercial sites, let us know about site rules

How we quote for fire rated sealant
There’s no set price list, because no two jobs are the same. What we look at:
- Working hours on commercial sites
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- Access, such as stairs, a lift or height
- Where the property is
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking

Other services in Charlbury
Different surfaces, different methods
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the sealant bonds.
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.
Why it’s worth doing now in Charlbury
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Around Charlbury, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why choose Mr Mastic in Charlbury
- Experience in homes, commercial sites and hotels
- Neat joints and a tidy finish
- 12-month guarantee on every job
- Any old sealant cut out fully, not covered over

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
