Workplaces and buildings in Wennington
Many London buildings have tight access and loading restrictions, 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.
Wennington is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Brady Primary School, fire-stopping around service openings should be restored whenever new services go in.

Fire rated sealant for homes and businesses in Wennington
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 service penetrations, plasterboard & masonry and flats & HMOs, and common reasons people get in touch are ordinary sealant used where a fire-rated product was needed and cracked or shrunken fire-rated sealant.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Wennington.
There’s a 12-month guarantee on every job.

When to call us in Wennington
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Look out for these signs:
- Ordinary sealant used where a fire-rated product was needed
- Door frames with gaps between frame and wall
- Fire stopping disturbed by later work
- Joints picked up in a fire-stopping survey
For landlords with property near Rainham (Essex) station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Wennington: your questions answered
Can you do fire rated sealant in Wennington?
Yes, Wennington is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Is parking a problem for a job in Wennington?
Parking in Wennington, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
How much does fire rated sealant cost in Wennington?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
Will we have a record of what was sealed?
Yes. We record the locations we’ve sealed and the products used for your files.
Do you seal gaps around fire door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant, to the product’s details. The door, its seals and closer are for a door specialist.
Can ordinary silicone be used in a fire-stopping gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.
How long will you be here?
That depends on the amount of work, but as a guide it takes from a few hours to a few days, depending on the number of gaps and the access. We’ll tell you when we quote.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.

There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes from a few hours to a few days, depending on the number of gaps and the access for a typical job.

Different surfaces, different methods
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run so there are no open sections left.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own and needn’t wait for anything else. 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.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Wennington
- Over 20 years’ experience
- Old sealant always removed completely
- We’re fully insured
- Neat joints and a tidy finish
See our cost guide or what customers say.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Doors that are not fire doors in the first place
- Fire risk assessments, which need a qualified assessor
- Sign-off of the building, which sits with building control or your assessor
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

What affects the quote in Wennington
The quote reflects the job in front of us. We take into account:
- The size of the job
- Any working-time requirements on site
- Which sealant suits the joint
- Whether the work is at height
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What we need to know
When you contact us, it’s useful to know:
- Pictures of the joints, sent by email
- The address or postcode of the job
- Roughly how big the job is
- Whether it has been sealed before
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
