Fire rated sealant for homes and businesses in Marston
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. We seal them with a product tested for that kind of gap. We work on linear gaps, flats & HMOs and service penetrations, and the jobs we see most are ordinary sealant used where a fire-rated product was needed and fire stopping disturbed by later work.
For holiday lets, converted business premises or a community building near Marston, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

How the job changes by surface
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
Door frames
Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- File the fire-stopping record where your assessor can find it
- Take photos of fire stopping before ceilings or boxing go back
- Report cracked or damaged seals as soon as you notice them
- Include hidden areas like risers in routine checks
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.
When something else is needed
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant will not put right:
- Construction that does not provide fire resistance on its own
- Certifying a building or signing off its fire safety
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Joints and surfaces we work on

- Service penetrations
- Linear gaps
- Plasterboard & masonry
- Flats & HMOs
Do you need fire rated sealant in Marston?
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Any of these means the joints need attention:
- Fire stopping disturbed by later work
- Fire seals that have cracked with movement
- Gaps filled with a product that is not fire-rated
- Sealant items on a fire risk assessment action list
Managing a site like St Nicholas Primary School? Then fire-stopping around service openings should be restored whenever new services go in.
What your quote should include

- Whether all the old sealant comes out first
- How long the guarantee is
- What insurance they hold
Commercial buildings in Marston
There are hotels and other places to stay in and around Marston. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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’re given, installing the product to its tested details.
Letting a property close to Oxford station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a church, hall or community building such as Church of St Nicholas, service openings in its walls need the right fire-rated sealant, as in any building.

Marston questions
Do you work for hotels and guest houses in Marston?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Do you cover smaller places like Marston?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Marston, along with the rest of our area.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
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.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.
What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Marston, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Preparing for the visit
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
