Common questions in Totteridge
Can parking be tricky for a visit in Totteridge?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you cover Totteridge for fire rated sealant?
Yes. Our work covers London and the South East, and Totteridge is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
How much does fire rated sealant cost in Totteridge?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one of the options. We use whichever the specification and tested details call for.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What should I tell you?
Tell us what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.
How we handle fire rated sealant in Totteridge
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. 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’re often asked to deal with gaps around pipes and cables through fire-resisting walls and ordinary sealant used where a fire-rated product was needed, on door frames, linear gaps and flats & HMOs.
In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in Totteridge, we agree timings and access before anything starts.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

What affects the cost of fire rated sealant
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
- The type of sealant required
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before work begins.
What we need to know
You do not need to know the technical terms. Just tell us:
- Where the job is, and your postcode
- Photos by email, if that’s easy
- Access, such as stairs, a lift or height
- The rough size of the job
Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or send us an email with the details and send pictures if you have them.
What the job involves on each surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and the locations noted.
How the visit works
The work is kept neat and contained to the joints we are treating. The job usually takes a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. In Totteridge, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive

Related advice
What happens if it’s left?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or email us and we will talk you through it.

Landlord and commercial work in Totteridge
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
When to call us in Totteridge
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
The problems people generally mention when they call include:
- Unsealed gaps where pipes and cables go through a wall
- Standard silicone or caulk in a fire-stopping gap
- Fire stopping disturbed by later work
- Linear gaps at the head of walls
Schools such as The Totteridge Academy are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
Questions to ask before booking
- Whether the sealant suits the joint
- How long the guarantee is
- What happens if the job turns out different
- How the joint is cleaned and prepared
Fire rated sealant in Totteridge: local notes
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’re given, installing the product to its tested details.
As a London address, Totteridge can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you look after a church, hall or community building such as St Andrew's Church, service openings in its walls need the right fire-rated sealant, as in any building.
