Fire-rated sealant in Upton, Greater London
Our applicators work in Upton on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.

- Gaps filled with a product that isn’t fire-rated
About our fire rated sealant in Upton
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We work on linear gaps, pipe & cable gaps and plasterboard & masonry, and the jobs we see most are linear gaps at the head of walls and gaps left after a refit or conversion.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Upton, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Different surfaces, different methods
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified room by room.
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Ask every contractor to reseal any fire stopping they disturb
- Keep photos of seals that will be hidden
- File the fire-stopping record where your assessor can find it
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are. In Upton, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Big openings where sealant alone isn’t the tested solution
- Walls or floors that weren’t built to resist fire
- Assessing a building’s fire safety
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
What we seal
- Door frames
- Flats & HMOs
- Service penetrations
- Linear gaps
- Plasterboard & masonry

- The old material and how stubborn it is
- The number of rooms or windows
- Mould in or behind the old joints
- How easy the joints are to reach

Common questions in Upton
Can parking be tricky for a visit in Upton?
Parking in Upton, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you work for landlords with property near Forest Gate station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you come to Upton?
Yes, we do. Upton is part of the area we cover.
How long does fire rated sealant take?
Most jobs take a few hours for a handful of gaps, and longer for a whole building. We will confirm how long when we quote.
How much does fire rated sealant cost in Upton?
Size, access and the old material all affect the cost. Ask us for a quote.
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.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Upton.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Commercial buildings in Upton
There are hotels and other places to stay in and around Upton. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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.
Community buildings like St Peter's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Rented homes near Forest Gate station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. As a London address, Upton can be tricky for parking: let us know about parking bays, permits or a driveway.
