How we handle fire rated sealant in Sanderstead
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We work on linear gaps, door frames and flats & HMOs, and the jobs we see most are open holes round services passing through fire walls and unsealed gaps around fire door frames.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Sanderstead, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
There’s a 12-month guarantee on every job, large or small.

What we do, step by step
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a job in Sanderstead, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- 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.
- Any non-fire-rated filler is removed 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 tricky access

More services for Sanderstead
Signs you need fire rated sealant in Sanderstead
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Keep an eye out for any of the following:
- Unsealed gaps where pipes and cables go through a wall
- New service routes left unsealed after building work
- Damaged fire sealant left by other trades
- Joints picked up in a fire-stopping survey
If you let a flat or house near Riddlesdown station, any gap left by new services in shared walls should be closed with a fire-rated product.
Questions to ask before you book
- What happens if the job turns out different
- What product goes in the joint
- Whether VAT is included
- Is the old sealant removed completely?
Aftercare tips
Aftercare is simple:
- Don’t paint over fire sealant until it has cured
- Keep pictures of seals that will be hidden
- Tell trades working in the building that fire seals must be put back
- Store the list of sealed gaps with your building paperwork
Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.
What the job involves on each surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for each gap size.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required.
Workplaces and buildings in Sanderstead
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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.
Community buildings like Church of All Saints are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like Gresham Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

What happens if it’s left?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job that does not depend on other work. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Sanderstead, the repair is bigger than a sealant job.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Can parking be tricky for a visit in Sanderstead?
Parking in Sanderstead, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you come to Sanderstead?
We do. Our applicators work in Sanderstead, and the service is the same as everywhere else.
Is there a guarantee?
Yes. Every job comes with our 12-month guarantee.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product.
