How we handle fire rated sealant in London Docklands
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We’re often asked to deal with unsealed gaps around fire door frames and old fire sealant that has split or come away, on pipe & cable gaps, door frames and plasterboard & masonry.
In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in London Docklands, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
Our work is backed for twelve months.

How we quote for fire rated sealant
Call for a quick quote. What matters most is:
- The product the joint needs
- The old material and how stubborn it is
- Any working-time requirements on site
- How easy the joints are to reach
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before any work starts.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Any access issues, like height or stairs
- The type of property
- A few photos by email, if you can
- If someone has resealed it before
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes from a few hours to a few days, depending on the number of gaps and the access. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
How to prepare
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions

Why act early in London Docklands
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. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Surface by surface
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.

London Docklands: your questions answered
Do you work for hotels and guest houses in London Docklands?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can parking be tricky for a visit in London Docklands?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Where do you work from?
Mr Mastic is based in Crawley. We cover London Docklands and the rest of Greater London, along with the rest of our area.
Do you certify the fire stopping?
That isn’t 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.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Will you assess my building’s fire safety?
No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Do you cover London Docklands?
Yes, we do. Our applicators work in London Docklands.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Keep the record of products and locations with your fire safety documents
- Check whether a sealant can be painted before decorating over it
- Photograph sealed gaps before they’re covered up
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
Signs you need fire rated sealant in London Docklands
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
Signs it’s time to call us include:
- Unsealed gaps around fire door frames
- Gaps left after a refit or conversion
- Joints picked up in a fire-stopping survey
- Fire stopping disturbed by later work
If you look after a building such as Tower Hamlets College, fire-stopping around service openings should be restored whenever new services go in.
