Fire rated sealant in St Margarets, done properly
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. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. If you’re dealing with unsealed gaps where pipes and cables go through a wall and damaged fire sealant left by other trades, we can put it right, whatever the surface.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in St Margarets cannot close.
Big or small, you get the same 12-month guarantee.

St Margarets questions
Do you work for landlords with property near St Margarets (London) station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you work for hotels and guest houses in St Margarets?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.

The process
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. In St Margarets, as in most of London, parking needs a little planning. 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.
- Old or unsuitable sealant is cut out and the gap 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.
- We record the locations and products used for your records.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive

How we quote for fire rated sealant
Every job gets its own quote. This is what makes a difference:
- The number of rooms or windows
- How much there is to do
- Whether there’s mould to deal with
- Whether the work is at height
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Where the property is
- Pictures of the joints, sent by email
- How we’d reach the joints
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved and send you a clear quote.
What sealant work can’t fix
Before booking, it’s worth knowing the limits:
- Issuing a fire rating or certificate for a building
- A wall that isn’t a fire-resisting element to begin with
- Doors that aren’t fire doors in the first place
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Linear gaps
- Plasterboard & masonry
- Pipe & cable gaps
- Door frames
- Service penetrations
- Flats & HMOs
Why it’s worth doing now in St Margarets
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we’ll tell you. 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 St Margarets, the repair is bigger than the sealant job would have been.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- Every job guaranteed for a year
- Full insurance on every job
- Over 20 years’ experience

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

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Check whether a sealant can be painted before decorating over it
- Get damaged fire seals looked at promptly
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Tell trades working in the building that fire seals must be put back
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.
When to call us in St Margarets
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 they leave doesn’t always get resealed.
The most common problems we see are:
- Seals cut through by electricians, plumbers or data installers
- New service routes left unsealed after building work
- Gaps around pipes and cables through fire-resisting walls
- Unsealed gaps around fire door frames
For landlords with property near St Margarets (London) station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
