How we handle fire rated sealant in Felsted
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. We work on flats & HMOs, plasterboard & masonry and service penetrations, and the jobs we see most are new service routes left unsealed after building work and fire seals that have cracked with movement.
For holiday lets, converted business premises or a community building near Felsted, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
All our work is covered by a 12-month guarantee.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Make resealing part of every contractor’s brief
- Keep the record of products and locations with your fire safety documents
- Plan fire stopping into any work that goes through walls or floors
- Take pictures of fire stopping before ceilings or boxing go back
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.
When it isn’t the sealant
We will not take on work that will not last, so these are the limits:
- Fire risk assessments, which need a qualified assessor
- Problems with the door itself rather than the gap around the frame
- Issuing a fire rating or certificate for a building
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Fire rated sealant in Felsted: 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’re given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of the Holy Cross, service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like Felsted Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

What the job involves on each surface
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.
Landlords, agents and businesses in Felsted
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
If you manage several properties in or around Felsted, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Felsted, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed

Advice
Why deal with it now?
Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. Around Felsted, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is usually more efficient than separate visits. We’ll give you a clear price for the lot.

What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
