Fire rated sealant in New Denham
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. Common call-outs are for holes left by a change of layout and unsealed gaps around fire door frames, across flats & HMOs, service penetrations and door frames.
Work in a small place like New Denham is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Our work is backed for twelve months, in New Denham and everywhere else we cover.

The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. In a small place like New Denham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- 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.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Tell us if parking is tricky

Why it’s worth doing now in New Denham
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Older cottages and farmhouses around New Denham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

When it is not the sealant
New sealant can’t fix everything, and we will tell you before work begins. Sealant will not put right:
- Big openings where sealant alone is not the tested solution
- Problems with the door itself rather than the gap around the frame
- Deciding what fire stopping a building needs
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Flats & HMOs
- Linear gaps
- Service penetrations
- Pipe & cable gaps
- Plasterboard & masonry
- Door frames
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 difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

What we’re called out for in New Denham
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.
It’s worth asking for a quote if you see:
- Damaged fire sealant left by other trades
- Gaps where walls meet ceilings or slabs
- Unsealed gaps around fire door frames
- Gaps around pipes and cables through fire-resisting walls
For buildings such as St Francis, service openings in its walls need the right fire-rated sealant, as in any building.

Workplaces and buildings in New Denham
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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 Denham station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as Hermitage Primary School, service openings in fire-resisting walls need checking after any refurbishment.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Report cracked or damaged seals as soon as you notice them
- Include hidden areas like risers in routine checks
- Store the list of sealed gaps with your building paperwork
- Plan fire stopping into any work that goes through walls or floors
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
What the job involves on each surface
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement.
