The process
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. In Richmond upon Thames, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start with the survey or action list, checking the size and surfaces of every gap.
- 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.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- Keep pets and children clear of the area while we work

About our fire rated sealant in Richmond upon Thames
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We are often asked to deal with ordinary sealant used where a fire-rated product was needed and gaps where walls meet ceilings or slabs, on service penetrations, linear gaps and door frames.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Richmond upon Thames, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Leave it or put it right?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Tell trades working in the building that fire seals must be put back
- Photograph sealed gaps before they’re covered up
- Include fire stopping when you schedule refits
- Look in service cupboards and ceiling voids from time to time
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Honest limits
To be straight with you, there are a few things sealant will not fix:
- Doors that aren’t fire doors in the first place
- Certifying a building or signing off its fire safety
- Fire risk assessments, which need a qualified assessor
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
