How we handle fire rated sealant in Twitton
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through. If you have old fire sealant that has split or come away and sealant items on a fire risk assessment action list, we can put it right, whatever the surface.
Work in a small place like Twitton is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Different surfaces, different methods
Flats and HMOs
Conversions normally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and record where they are.
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.
What happens if it’s left?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. In a small place like Twitton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Advice
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Do you need fire rated sealant in Twitton?
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
Keep an eye out for these signs:
- Cracked or shrunken fire-rated sealant
- Joints picked up in a fire-stopping survey
- Gaps filled with a product that is not fire-rated
- Open gaps behind door architraves
Letting a property close to Dunton Green station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Include fire stopping when you schedule refits
- Check whether a sealant can be painted before decorating over it
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Make resealing part of every contractor’s brief
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
