Fire rated sealant in Mortlake
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you have fire stopping disturbed by later work and joints picked up in a fire-stopping survey, we can put it right, on door frames, flats & HMOs and service penetrations alike.
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 Mortlake, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Every job comes with our one-year guarantee.

What affects the cost of fire rated sealant
Jobs vary more than people expect. What affects the quote:
- When we can work, for business premises
- How easy the joints are to reach
- How many areas need sealing
- The size of the job
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
When you contact us, these details help:
- The rough size of the job
- Where the property is
- If someone has resealed it before
- How we’d reach the joints
For fire rated sealant in Mortlake, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and you’ll get a clear quote before work begins.
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Walls or floors that weren’t built to resist fire
- Certifying a building or signing off its fire safety
- Fire doors that need new seals, closers or hardware
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.
Surfaces we seal
- Linear gaps
- Door frames

- Service penetrations
The process
At the end, we look at the finished work together. The work normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the amount of work. In Mortlake, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks

Questions from Mortlake
Can you help a landlord with a rental near Mortlake station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is Mortlake in your area for fire rated sealant?
Yes, Mortlake is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What information do you need?
Tell us what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Do you have insurance?
Yes, we’re fully insured.
Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What we’re called out for in Mortlake
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
The most common problems we see are:
- Joints picked up in a fire-stopping survey
- Gaps left after a refit or conversion
- Gaps filled with a product that isn’t fire-rated
- Fire seals that have cracked with movement
Letting a property close to Mortlake station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

What the job involves on each surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.
What fire rated sealant looks like in Mortlake
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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Community buildings like All Saints' Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Mortlake is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
