Fire-rated sealant in Bletchley, Milton Keynes
Fire-stopping gaps in Bletchley need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Seals cut through by electricians, plumbers or data installers
- New service routes left unsealed after building work
- Linear gaps at the head of walls
What happens if it’s left?
Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again when the building is next checked. Around Bletchley, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Why us?
- We leave the area clean and tidy
- ARBOMaster approved applicator
- We are fully insured
- Anti-fungal sanitary silicone in wet areas

Fire rated sealant in Bletchley, done properly
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That’s the part we focus on, gap by gap. If you have gaps where walls meet ceilings or slabs and fire seals that have cracked with movement, we can help, whatever the surface.
Commercial jobs in a town like Bletchley range from shops and offices to schools and small business units. All of them have washroom and kitchen joints, and many have fire-rated joints around pipes and cables.
All our work comes with a 12-month guarantee, wherever you are in Milton Keynes.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Problems with the door itself rather than the gap around the frame
- Walls or floors that weren’t built to resist fire
- Issuing a fire rating or certificate for a building
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.

Fire rated sealant around Bletchley
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you let a flat or house near Bletchley station, 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 St. Mary's Church, service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Holne Chase Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Different surfaces, different methods
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing so the sealant bonds.
Service penetrations
New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth.
FAQs for Bletchley
Is there a guarantee on fire rated sealant in Bletchley?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you do fire rated sealant in Bletchley?
Yes, Bletchley is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.
How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We’ll give you a better idea when we quote.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you seal gaps around fire door frames?
Yes, if the gap is within the product’s tested range. Our work is the gap around the frame and we will tell you if we spot problems with the door.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.

How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Parking in a town like Bletchley is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We start with the survey or action list, checking the size and surfaces of every gap.
- 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.
- Locations and products are noted so you have them on file.
How to prepare
- Keep children and pets away from the work area
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
How we quote for fire rated sealant
We quote each job individually. These are the things that affect it:
- How many areas need sealing
- Mould in or behind the old joints
- The old material and how stubborn it is
- Whether the work is at height
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
When you contact us, these details help:
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
To get a quote, call 0345 464 0079 or email us with the location and a short description of the problem. You’ll have a clear quote before work begins.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
