How we handle fire rated sealant in Ditton Hill
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We are often asked to deal with gaps where walls meet ceilings or slabs and holes left by a change of layout, on door frames, linear gaps and pipe & cable gaps.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Ditton Hill.
There’s a 12-month guarantee on every job.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Issuing a fire rating or certificate for a building
- Fire risk assessments, which need a qualified assessor
- Problems with the door itself rather than the gap around the frame
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What else we do in Ditton Hill
Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. 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.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Fire rated sealant in Ditton Hill: local notes
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
For site and facilities teams at buildings such as Long Ditton Infant and Nursery School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there. Rented homes near Surbiton station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before work begins.
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.
What fire rating will the seal have?

Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Different surfaces, different methods
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
