What fire rated sealant looks like in St Mary Cray
Commercial buildings in London often have strict access rules and limited loading, 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, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
For buildings such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to St Mary Cray station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Fire rated sealant in St Mary Cray, done properly
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. If you are dealing with joints picked up in a fire-stopping survey and unsealed gaps where pipes and cables go through a wall, we can put it right, whatever the surface.
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 St Mary Cray.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
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.
What we do, step by step
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job usually takes from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. In St Mary Cray, 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.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

Advice
When to call us in St Mary Cray
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
Most people get in touch after spotting one of these:
- Gaps where walls meet ceilings or slabs
- Gaps left after a refit or conversion
- Open gaps behind door architraves
- Gaps filled with a product that is not fire-rated
As a London address, St Mary Cray can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- How long the guarantee is
- What happens if the job turns out different
- Which colour the sealant will be
- Whether all the old sealant comes out first
What happens if it’s left?
Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we’ll tell you. In a flat in St Mary Cray, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How the job changes by surface
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before we start.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.
Landlord and commercial work in St Mary Cray
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
