How we handle fire rated sealant in Muswell Hill
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We work on service penetrations, linear gaps and door frames, and the jobs we see most are gaps left after a refit or conversion and standard silicone or caulk in a fire-stopping gap.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Muswell Hill, we agree timings and access before anything starts.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Do you need fire rated sealant in Muswell Hill?
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
The problems people generally mention when they call include:
- Unsealed gaps around fire door frames
- Cracked or shrunken fire-rated sealant
- Fire stopping disturbed by later work
- Open holes round services passing through fire walls
If you let a flat or house near Alexandra Palace station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

The process
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work normally takes from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Muswell Hill. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
- Every location is recorded with the product used for your records.
Before we arrive
- Tell us if parking is tricky
- Clear the area around the work
- Let us know if you’ve seen damp or leaks

Different surfaces, different methods
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point against the product’s tested range.
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Construction that does not provide fire resistance on its own
- Large holes that need a different fire-stopping system
- Deciding what fire stopping a building needs
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

What fire rated sealant looks like in Muswell Hill
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For site and facilities teams at buildings such as Muswell Hill Primary School, service openings in fire-resisting walls need checking after any refurbishment. Muswell Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Why deal with it now?
Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In a flat in Muswell Hill, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
Why book with us
- Experience in homes, commercial sites and hotels
- We are fully insured
- We never seal over old sealant
- One-year guarantee on every job
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- File the fire-stopping record where your assessor can find it
- Report cracked or damaged seals as soon as you notice them
- Look in service cupboards and ceiling voids from time to time
- Ask which product was used before you paint
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Your questions about fire rated sealant in Muswell Hill
Do you work for landlords with property near Alexandra Palace station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Can parking be tricky for a visit in Muswell Hill?
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.
Can I use normal mastic around a pipe through a fire wall?
No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.
Are you insured?
Yes, we are fully insured for domestic and commercial work.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What affects the cost of fire rated sealant
For a quick quote, just ask. What matters most is:
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
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 we need extra access for height. We take all of that into account in your quote.
Helping us quote
When you call or email, it’s useful to know:
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- The problem you’ve noticed
- Any previous sealing or DIY work
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, ring 0345 464 0079 or drop us an email.
