Fire-rated sealant in Sudbury Hill, Greater London
Our applicators work in Sudbury Hill on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.
- Ordinary sealant used where a fire-rated product was needed
- Gaps where walls meet ceilings or slabs
- Unsealed gaps where pipes and cables go through a wall
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Openings too large for sealant, which need batts, boards or another system
- Sign-off of the building, which sits with building control or your assessor
- Problems with the door itself rather than the gap around the frame
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
Joints and surfaces we work on
- Pipe & cable gaps
- Door frames
- Service penetrations
- Linear gaps
- Flats & HMOs
- Plasterboard & masonry
Fire rated sealant in Sudbury Hill, done properly
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We are often asked to deal with new service routes left unsealed after building work and fire stopping disturbed by later work, across plasterboard & masonry, flats & HMOs and door frames.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Sudbury Hill, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Commercial buildings in Sudbury Hill
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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
For buildings such as Church of St Andrew, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Sudbury Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Your questions about fire rated sealant in Sudbury Hill
Do you work in hotels near Sudbury Hill?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Is parking a problem for a job in Sudbury Hill?
Parking in Sudbury Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
How long does the job take?
As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Larger jobs naturally take longer, and we will tell you how long to expect.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before work begins.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do you do fire sealant around door frames?
Yes, if the gap is within the product’s tested range. Our work is the gap around the frame.
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean. 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.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Preparing for the visit
- Mention any parking rules near the property
- Mention any tricky access
- Clear items away from the joints we’re working on

How the job changes by surface
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for the gap we are sealing.
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.
What happens if it’s left?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that does not depend on other work. In a flat in Sudbury Hill, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we will talk you through it.

When to call us in Sudbury Hill
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
Signs it’s time to call us include:
- Fire seals that have cracked with movement
- Joints picked up in a fire-stopping survey
- Open joints along the top of partitions
- Gaps around pipes and cables through fire-resisting walls
If you let a flat or house near Sudbury & Harrow Road station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
What your quote should include
- Whether VAT is included
- What preparation is included
- How hidden problems are handled
- The length of the guarantee
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What affects the quote in Sudbury Hill
The price is agreed before any work begins. It’s based on:
- The product the joint needs
- The old material and how stubborn it is
- Whether there’s mould to deal with
- The number of rooms or windows
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
When you call or email, it’s useful to know:
- If someone has resealed it before
- The problem you’ve noticed
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
