Fire rated sealant for homes and businesses in Moreton
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. If you’re dealing with damaged fire sealant left by other trades and gaps where walls meet ceilings or slabs, we can put it right.
In a village or hamlet like Moreton, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
All our work is covered by our one-year guarantee, wherever you are in Oxfordshire.

Your questions about fire rated sealant in Moreton
Will you come out to Moreton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you take on hotel work around Moreton?
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.
Can you tell me which gaps need fire stopping?
No, assessment isn’t something we do. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job.

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Fire rated sealant around 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’re given, installing the product to its tested details. There are hotels and other places to stay in and around Moreton. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
If you look after a building such as Lord Williams's School, gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Haddenham & Thame Parkway station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Moreton is about 1 mile south-west of Thame, in Oxfordshire. Whether you are in the middle of Moreton or further out, we cover fire rated sealant for every kind of property. Moreton is one of 443 towns and villages in Oxfordshire where we work. Oxford is on our list too, around 10 miles away.

Signs you need fire rated sealant in Moreton
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
Look out for any of the following:
- Cracked or shrunken fire-rated sealant
- Open holes round services passing through fire walls
- Door frames with gaps between frame and wall
- Ordinary sealant used where a fire-rated product was needed
Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
Questions to ask before booking
- Who does the work, and how experienced they are
- How hidden problems are handled
- What preparation is included
- Whether the sealant suits the joint
Surface by surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for each gap size.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail.
Landlord and commercial work in Moreton
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What we do, step by step
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 from a few hours to a few days, depending on the number of gaps and the access, including the tidy-up. In a small place like Moreton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Getting ready for the visit
- Mention any tricky access
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

What happens if it’s left?
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. In a small place like Moreton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before we start.
