- Linear gaps at the head of walls
- Gaps filled with a product that isn’t fire-rated
- Unsealed gaps where pipes and cables go through a wall
How to look after the new joints
So the new joints stay in good condition:
- Store the list of sealed gaps with your building paperwork
- Make resealing part of every contractor’s brief
- Flag any open gap you spot round a pipe or cable
- Allow for resealing whenever new services are run
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t, so ask us which we used.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.
About our fire rated sealant in Dagenham Green
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment for buildings in Dagenham Green. Send us the list or the survey and we will quote for the fire-rated sealant work on it. If you have fire stopping disturbed by later work and ordinary sealant used where a fire-rated product was needed, we can put it right.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Dagenham Green, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. 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.
- 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.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed

Advice
Commercial buildings in Dagenham Green
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. 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 work to the specification you’re given, installing the product to its tested details.
Schools such as Marsh Green Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. For landlords with property near Dagenham Dock station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Landmarks near Dagenham Green
Typical jobs here are in homes near Dagenham Park Community School, Cross Keys pub and Parsloes Park and the streets around them.

What happens if it’s left?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Dagenham Green, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Signs you need fire rated sealant in Dagenham Green
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
These are the problems we’re asked about most:
- Gaps where walls meet ceilings or slabs
- Door frames with gaps between frame and wall
- Gaps left after a refit or conversion
- Gaps filled with a product that is not fire-rated
Community buildings like St Martin's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
What your quote should include
- What insurance they hold
- The length of the guarantee
- How the joint is cleaned and prepared
- Who turns up on the day
Honest limits
We will not take on work that will not last, so these are the limits:
- Openings too large for sealant, which need batts, boards or another system
- Doors that aren’t fire doors in the first place
- Issuing a fire rating or certificate for a building
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.
Joints and surfaces we work on
- Plasterboard & masonry

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Common questions in Dagenham Green
Is parking a problem for a job in Dagenham Green?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you cover Dagenham Green for fire rated sealant?
Yes. Our work covers London and the South East, and Dagenham Green is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available and agree one before we start.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Do you provide details of the products used?
Yes. We record the locations we’ve sealed and the products used for your files.
What’s the difference between intumescent and fire-rated sealant?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all.
Do you work in flats, HMOs and commercial buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
