How we handle fire rated sealant in Bell Green
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. If you’re dealing with door frames with gaps between frame and wall and damaged fire sealant left by other trades, we can put it right.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Bell Green, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Bell Green questions
Can you do fire rated sealant in Bell Green?
Yes, Bell Green is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Can parking be tricky for a visit in Bell Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you certify the fire stopping?
Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, large or small.
Commercial buildings in Bell Green
Commercial buildings in London often have strict access rules and limited loading, 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a building such as Haseltine Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like St Michael's and All Angels are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What’s near Bell Green
Typical jobs here are in homes near Allenby Tutorial Trust, Mayow Park and Fellowship Inn and the streets around them. There’s a railway station in Bell Green itself: Lower Sydenham station. Other landmarks nearby include Lewisham Shopping Centre (2.3 miles north-east) and Horniman Museum and Gardens (1.4 miles north-west). Not far away are Dacres Wood and Knight's Hill.
The process
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Bell Green. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Getting ready for the visit
- Mention if the joints have been sealed before
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit

Advice
Different surfaces, different methods
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for the gap we are sealing.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep photos of seals that will be hidden
- Never patch a fire seal with standard sealant
- Keep the record of products and locations with your fire safety documents
- Plan fire stopping into any work that goes through walls or floors
Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. We can tell you which product we used.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Leave it or put it right?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

- Fully insured

What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- Issuing a fire rating or certificate for a building
- Deciding what fire stopping a building needs
- Problems with the door itself rather than the gap around the frame
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

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 be quoted together.
Common problems we fix in Bell Green
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 usually mention when they call are:
- Unsealed gaps around fire door frames
- Open joints along the top of partitions
- Gaps left after a refit or conversion
- Fire stopping disturbed by later work
For landlords with property near Lower Sydenham station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
