The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. In a London area like Tottenham, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- 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 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 files.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks

How we handle fire rated sealant in Tottenham
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on, gap by gap. We work on flats & HMOs, linear gaps and pipe & cable gaps, and the jobs we see most are open joints along the top of partitions and ordinary sealant used where a fire-rated product was needed.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Tottenham, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
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.

Your questions about fire rated sealant in Tottenham
Is parking a problem for a job in Tottenham?
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 Tottenham for fire rated sealant?
Yes, Tottenham is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
How long does the job take?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Is standard sealant good enough for a fire gap?
No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.
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.
Where do you work from?
Mr Mastic is based in Crawley. We cover Tottenham and the rest of Greater London.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Check risers, ceiling voids and cupboards during building checks
- Ask which product was used before you paint
- Take pictures of fire stopping before ceilings or boxing go back
- Get damaged fire seals looked at promptly
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Fire risk assessments, which need a qualified assessor
- Big openings where sealant alone isn’t the tested solution
- Doors that aren’t fire doors in the first place
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal

What else we do in Tottenham
Why act early in Tottenham
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. 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.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.
Why us?
- 12-month guarantee on every job
- 4.9 on Google from 180+ five-star reviews
- ARBOMaster approved applicator
- Full insurance on every job
Different surfaces, different methods
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.
Door frames
Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Quotes for fire rated sealant in Tottenham
We quote each job individually. These are the things that affect it:
- Whether the work is at height
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The product the joint needs
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- A few photos by email, if you can
- Where the property is
We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or drop us an email and describe the job and send photos if you have them.
Commercial buildings in Tottenham
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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Community buildings like Church of St Mary the Virgin are part of the picture too: gaps around pipes and cables are worth checking after any building work there. As a London address, Tottenham can be tricky for parking: let us know about parking bays, permits or a driveway. Managing a site like The Mulberry Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.
