Fire rated sealant for homes and businesses in Bow Common
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 apply it to the depth its tested detail calls for. We’re often asked to deal with gaps left after a refit or conversion and unsealed gaps around fire door frames, on service penetrations, plasterboard & masonry and door frames.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Bow Common needs to stay open, work can be planned outside normal hours.
All of our work is guaranteed for twelve months, in Bow Common and everywhere else we cover.

Why it’s worth doing now in Bow Common
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Bow Common, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

Questions from Bow Common
I let a flat near Limehouse station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Do you work in hotels near Bow Common?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you do fire sealant around door frames?
Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.
Will you assess my building’s fire safety?
No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.
What fire rating will the seal have?
We don’t certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
When to call us in Bow Common
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.
These are the problems we are asked about most:
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
- Gaps where walls meet ceilings or slabs
- Gaps left after a refit or conversion
As a London address, Bow Common can be tricky for parking: let us know about parking bays, permits or a driveway.
Comparing quotes
- How long to leave it before use
- The length of the guarantee
- Who turns up on the day
- Whether all the old sealant comes out first
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Different surfaces, different methods
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Flats and HMOs
Conversions generally leave a mix of old and new service holes. We seal the ones on your specification with a tested product.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Fire rated sealant around Bow Common
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 work to the specification you’re given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
If you let a flat or house near Limehouse station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like St Paul's Way Trust School? Then fire-stopping around service openings should be restored whenever new services go in.

Advice
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Fire doors that need new seals, closers or hardware
- Sign-off of the building, which sits with building control or your assessor
- Big openings where sealant alone is not the tested solution
