About our fire rated sealant in Collier Row
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on, gap by gap. We work on door frames, linear gaps and pipe & cable gaps, and the jobs we see most are open holes round services passing through fire walls and gaps left after a refit or conversion.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Collier Row, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Leave it or put it right?
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 work involved is often modest. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Collier Row.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it 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 Collier Row. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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 and the gap 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.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

Surface by surface
Flats and HMOs
Conversions generally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required.
What we can’t put right
We will always be straight with you, so here’s what sealant can’t fix:
- A wall that isn’t a fire-resisting element to begin with
- Big openings where sealant alone is not the tested solution
- Certifying a building or signing off its fire safety
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.

Fire rated sealant around Collier Row
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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
For landlords with property near Romford station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Schools such as Rise Park Infant School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
