- Holes left by a change of layout
- Open joints along the top of partitions
The process
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. Somewhere as small as North Moreton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- 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.
Before we arrive
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

About our fire rated sealant in North Moreton
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. Common call-outs are for fire stopping disturbed by later work and open gaps behind door architraves, across flats & HMOs, service penetrations and plasterboard & masonry.
In a village or hamlet like North Moreton, 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.
Big or small, you get the same 12-month guarantee in North Moreton and across Oxfordshire.

Looking after it afterwards
After the cure time, these simple habits help:
- Keep pictures of seals that will be hidden
- Check whether a sealant can be painted before decorating over it
- Store the list of sealed gaps with your building paperwork
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
Leave it or put it right?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Where a wall is exposed, as many are in small places like North Moreton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

When to call us in North Moreton
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.
Most people get in touch after spotting one of these:
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
- Damaged fire sealant left by other trades
- Gaps where walls meet ceilings or slabs
Managing a site like South Moreton Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

Your questions about fire rated sealant in North Moreton
I let a flat near Didcot Parkway station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like North Moreton?
Yes, North Moreton is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can you fill the gap behind a fire door frame?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
What fire rated sealant looks like in North Moreton
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 are given, installing the product to its tested details.
For landlords with property near Didcot Parkway station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
