What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It 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 Streatham Park. It helps if you can point us to a visitor permit or a bay close to the door.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- 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.
Preparing for the visit
- Clear the area around the work
- Let us know about parking restrictions
- Mention any tricky access

Why it’s worth doing now in Streatham Park
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. 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 Streatham Park, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours for a handful of gaps, and longer for a whole building. We’ll give you a better idea when we quote.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.

Do you have insurance?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Doors that aren’t fire doors in the first place
- Issuing a fire rating or certificate for a building
- Construction that does not provide fire resistance on its own
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal
- Flats & HMOs
- Service penetrations
- Door frames
- Pipe & cable gaps
- Linear gaps
- Plasterboard & masonry
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What the job involves on each surface
Plasterboard walls
We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.
What we are called out for in Streatham Park
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
Any of these means the joints need attention:
- Fire stopping disturbed by later work
- Open gaps behind door architraves
- Sealant items on a fire risk assessment action list
- Cracked or shrunken fire-rated sealant
Community buildings like Parish Church of St Alban are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Fire rated sealant around Streatham Park
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. 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 work to the specification you’re given, installing the product to its tested details.
Schools such as St Leonard's Church of England Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. As a London address, Streatham Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
