Fire rated sealant in Widford
We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. If you’re dealing with open gaps behind door architraves and gaps left after a refit or conversion, we can help.
Somewhere as small as Widford, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Looking after it afterwards
So the new joints stay in good condition:
- Check whether a sealant can be painted before decorating over it
- Photograph sealed gaps before they’re covered up
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Make resealing part of every contractor’s brief
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
Leave it or put it right?
Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Older cottages and farmhouses around Widford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What fire rated sealant looks like in Widford
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 site and facilities teams at buildings such as Mildmay Junior School, gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

How we quote for fire rated sealant
Every job gets its own quote. This is what makes a difference:
- The product the joint needs
- Access and height
- The old material and how stubborn it is
- Whether there’s mould to deal with
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- The address or postcode of the job
- The rough size of the job
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
To get a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll give you a clear quote before any work starts.
When to call us in Widford
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.
The problems people usually mention when they call are:
- Ordinary sealant used where a fire-rated product was needed
- Linear gaps at the head of walls
- Unsealed gaps around fire door frames
- Fire stopping disturbed by later work
Letting a property close to Chelmsford station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
What to look for in a quote
- What product goes in the joint
- How much experience the applicator has
- Are they insured?
- Is the old sealant removed completely?
What happens on the day
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Widford, 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.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
Preparing for the visit
- Clear the area around the work
- Tell us if parking is tricky

Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is the work guaranteed?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Can ordinary silicone be used in a fire-stopping gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.
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. The order of work and access are planned with you.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
DIY versus a professional finish
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 fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Surface by surface
Door frames
Frame gaps are generally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
