DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, 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.
Fire rated sealant in Clapham Park, 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. We are often asked to deal with gaps where walls meet ceilings or slabs and door frames with gaps between frame and wall, across linear gaps, pipe & cable gaps and door frames.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Clapham Park, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

The process
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Clapham Park. 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.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height

Advice
Do you need fire rated sealant in Clapham Park?
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
Signs it’s time to call us include:
- Door frames with gaps between frame and wall
- Gaps left after a refit or conversion
- Ordinary sealant used where a fire-rated product was needed
- Fire stopping disturbed by later work
Clapham Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- How the colour is chosen
- How hidden problems are handled
- What insurance they hold
- Is VAT in the price?

Leave it or put it right?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

What we cannot put right
We will always be straight with you, so here’s what sealant cannot fix:
- Issuing a fire rating or certificate for a building
- Construction that does not provide fire resistance on its own
- Assessing a building’s fire safety
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

Your questions about fire rated sealant in Clapham Park
Can you help a landlord with a rental near Clapham High Street station?
Yes. We work for landlords and letting agents as well as homeowners. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Can parking be tricky for a visit in Clapham Park?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Can you work in occupied buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we’ll plan around it.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Where are you based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Do you do fire sealant around door frames?
Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Commercial buildings in Clapham Park
Clapham Park has hotels and guest accommodation in and around it. 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.
Schools such as Glenbrook Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. For landlords with property near Clapham High Street station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length leaving no stretch unsealed.
