Questions from Shadwell
Do you work in hotels near Shadwell?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Is parking a problem for a job in Shadwell?
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 certify the fire stopping?
Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.
Is there a guarantee?
Yes. Every job comes with our one-year guarantee.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do you cover Shadwell?
We do. Our applicators work in Shadwell, and the service is the same as everywhere else.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Shadwell. It helps if you can point us to a visitor permit or a bay close to the door.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- 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.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can

What affects the cost of fire rated sealant
You will get a clear quote before any work starts. It’s based on:
- Whether there’s mould to deal with
- How much there is to do
- The type of sealant required
- The old material and how stubborn it is
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Helping us quote
You don’t need to know the technical terms. Just tell us:
- Any access issues, like height or stairs
- If someone has resealed it before
- What’s wrong with the joints now
- Pictures of the joints, sent by email
Every job is quoted individually. Simply ring 0345 464 0079 or email us and describe the job.
When it is not the sealant
Sealant is not the answer to every problem, and we will tell you before work begins. It won’t solve:
- A wall that is not a fire-resisting element to begin with
- Certifying a building or signing off its fire safety
- Fire risk assessments, which need a qualified assessor
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Where we work in Shadwell
- Plasterboard & masonry
- Flats & HMOs
- Door frames
- Pipe & cable gaps
- Linear gaps
- Service penetrations
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Include hidden areas like risers in routine checks
- Plan fire stopping into any work that goes through walls or floors
- Make resealing part of every contractor’s brief
- Report cracked or damaged seals as soon as you notice them
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

What else we do in Shadwell
Different surfaces, different methods
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each, and tell you if sealant alone isn’t the right fix.
Why act early in Shadwell
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Fire rated sealant around Shadwell
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. Shadwell has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
For buildings such as St Paul's Church, service openings in its walls need the right fire-rated sealant, as in any building. If you let a flat or house near Wapping station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Peter Hills with St Mary's and St Paul's CofE Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
