How the job changes by surface
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and record where they are.
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size.
How we handle fire rated sealant in Tottenham Green
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. If you’re dealing with gaps filled with a product that isn’t fire-rated and door frames with gaps between frame and wall, we can put it right, on pipe & cable gaps, service penetrations and door frames alike.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Tottenham Green cannot close.
You get a 12-month guarantee, the same in Tottenham Green as everywhere else we work.

Why deal with it now?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Tottenham Green, the repair is bigger than the sealant job would have been.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

What else we do in Tottenham Green
Commercial buildings in Tottenham Green
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. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
For landlords with property near Seven Sisters station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of Holy Trinity are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes from a few hours to a few days, depending on the number of gaps and the access from start to finish. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Tottenham Green. It helps if you can point us to a visitor permit or a bay close to the door.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property

What we’re called out for in Tottenham Green
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where walls meet ceilings or slabs
- Open gaps behind door architraves
- Unsealed gaps where pipes and cables go through a wall
- Old fire sealant that has split or come away
Tottenham Green is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What your quote should include
- Whether they seal over old material or remove it
- The length of the guarantee
- What the quote includes, VAT included or not
- What product goes in the joint

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

Tottenham Green: your questions answered
Is parking an issue for fire rated sealant in Tottenham Green?
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 work for landlords with property near Seven Sisters station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
How long does the job take?
That depends on the amount of work, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We’ll give you a better idea when we quote.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
How much does fire rated sealant cost in Tottenham Green?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or email us and tell us what needs doing and where.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
